ChatGPT answers, unedited

For a marketing agency managing multiple clients, I’d focus less on “influencer discovery” and more on multi-brand program management + creator attribution + commission rules + payouts + reporting.

Based on the current 2026 feature sets, I’d shortlist these:

My take

If your core business is running performance-based creator programs for multiple clients, I'd start with impact.com.

It is particularly relevant because it combines creators, affiliates, referrals and other partner types in one platform, rather than treating creator marketing and affiliate marketing as separate systems. Its creator product covers the workflow from discovery through payout, and the company explicitly positions it for agencies as well as brands. impact.com impact.com

That becomes valuable if, for example, Client A has:

• TikTok creators at 15% commission
• Instagram creators using unique codes
• YouTube creators paid CPA
• traditional affiliates at 10%
• tiered bonuses after $10k/$25k in sales

…and you want all of that measured in one performance system.

GRIN would be my other serious evaluation. It's more creator/DTC-centric and has particularly deep creator-program functionality: recruitment, affiliate setup, product fulfillment, commission tiers, performance tracking and automated payouts. GRIN GRIN - Influencer Marketing Software

Modash is attractive if creator discovery is a major part of what your agency sells. It now combines discovery with partnership management, affiliate tracking and payments, but its positioning is more Shopify/in-house-team oriented than agency/multi-client oriented. Modash

The important distinction

I'd actually separate your requirements into two possible models:

A. “We run influencer campaigns that sometimes include commissions.”
→ GRIN / Aspire

B. “We operate ongoing creator affiliate programs where creators are essentially a performance sales channel.”
→ impact.com / GRIN

For an agency, B is where impact.com becomes especially interesting, because you can manage creators alongside conventional affiliates and referrals rather than creating a separate system for every type of partner. impact.com

If you tell me roughly how many clients, creators per client, ecommerce platforms (Shopify/Amazon/etc.), and channels (TikTok/Instagram/YouTube/Amazon/etc.), I can narrow this to 2–3 platforms and compare the actual agency workflow, pricing, white-label/client reporting, commission rules, and payout capabilities.

For a marketing agency managing creator commission programs across multiple clients and channels, I’d shortlist the platforms differently than I would for a single DTC brand.

My shortlist

1. impact.com — probably the first platform I'd demo

impact.com

The key advantage for your use case is that it treats creators and affiliates as parts of the same partnership infrastructure. You can run commission-based creator programs alongside traditional affiliates, referrals and other partner types rather than maintaining separate systems. It supports discovery, contracting, tracking, commissions/payouts, reporting and partner management. impact.com impact.com

More importantly for an agency, impact.com explicitly has an agency partner program and says its platform is used by 700+ active agency-managed brands. impact.com

I'd lean toward this if your clients are doing things like:

• Instagram/TikTok creators → affiliate links or promo codes
• TikTok Shop
• Shopify/ecommerce
• Traditional affiliate publishers
• Customer/referral programs
• Different commission structures by client, product or creator
• Client-level reporting and payouts

The big differentiator is that you're not really buying an "influencer marketing tool"; you're buying partnership/commission infrastructure.

2. GRIN — if the agency is primarily creator marketing

grin.co

GRIN is worth serious consideration if your agency's workflow revolves around finding creators → recruiting them → sending products → managing campaigns → tracking sales/commission → paying creators. Its current product includes both creator management and an affiliate marketing workflow. GRIN - Influencer Marketing Software

I'd investigate GRIN particularly if your clients are predominantly DTC/ecommerce brands and the creator relationship itself is as important as the affiliate infrastructure.

One thing I'd specifically test in a demo: how cleanly your agency can isolate multiple client workspaces and consolidate reporting across them. Third-party comparisons indicate GRIN has agency-oriented capabilities, but the exact packaging is worth confirming before signing. Storika

3. Aspire — creator/ambassador-heavy programs

aspire.io

Aspire combines creator discovery, relationship management, affiliate programs, product seeding, content and ROI measurement. It also has an agency service offering. Aspire

I'd put this higher on the list if clients want ambassador communities and creator relationships, rather than simply "here's a tracking link; earn 15%."

4. CreatorIQ — when your clients are enterprise

creatoriq.com

This becomes more interesting if you're an agency managing large brands, multiple markets, substantial creator rosters and demanding reporting/finance requirements. It's more enterprise-oriented than the typical SMB creator-affiliate platform.

I wouldn't automatically choose it for smaller clients because the implementation and commercial model can be substantially heavier.

What I'd do in your position

I'd start with impact.com vs. GRIN vs. Aspire, with CreatorIQ as the enterprise option.

The deciding question isn't really "which has the most creator features?" It's:

Do you want your agency's system of record to be a creator-management platform, or a partnership/commission platform?

If your clients are asking you to run performance programs where creators get paid based on sales, I'd lean impact.com.

If they're asking you to run the entire creator relationship and content operation, I'd put GRIN/Aspire into the evaluation.

And if you have a lot of clients, I'd make these non-negotiable requirements in the demo:

• Separate client workspaces with no cross-client data leakage
• Agency-level dashboard across all clients
• Per-client reporting/exports
• Creator-level commission rules
• Product/SKU-specific commission rates
• Coupon + affiliate-link attribution
• TikTok Shop support
• Instagram/YouTube/TikTok tracking
• Automated creator payouts and tax/payment handling
• Refund/cancellation-aware commission calculations
• Multiple attribution windows
• Client-facing/white-label reporting
• API/webhooks and data export
• Role-based permissions
• Ability to bring your existing creator roster rather than forcing marketplace discovery
• Clear pricing for agency-managed clients, rather than pricing that explodes as you add brands

If you tell me roughly how many clients/brands you manage, how many creators per client, and which channels matter most (TikTok Shop, Shopify, Instagram, Amazon, YouTube, etc.), I can narrow this to 2–3 platforms and lay out the exact architecture I'd use for your agency.

For a marketing agency managing multiple clients, I’d avoid picking a standard influencer marketplace first. You want a creator commerce / affiliate operations platform that can handle:

• Separate client workspaces (so Brand A never sees Brand B data)
• Creator discovery + CRM
• Commission rules and tracking
• Affiliate links/codes
• TikTok Shop / Instagram / YouTube / Shopify attribution
• Creator contracts + payouts
• Client-facing dashboards and reports
• Team permissions

The “best” choice depends on whether you’re primarily running affiliate/commission programs or broader influencer campaigns.

Best overall fits for an agency

1. GRIN — Best for established brands + agencies with Shopify-heavy clients

Best if: Your clients sell products online and need ambassador programs.

Strengths:

• Strong creator relationship management
• Product seeding workflows
• Affiliate links/codes
• Ecommerce integrations
• Good for long-term ambassador programs

Weakness:

• Can feel built more for brands than agencies managing dozens of clients.

2. Aspire — Best enterprise-grade creator programs

Best if: You manage larger consumer brands.

Strengths:

• Large creator database
• Campaign management
• Content rights workflows
• Reporting
• Payments

Weakness:

• Usually more expensive and heavier operationally.

3. Upfluence — Best for ecommerce + affiliate attribution

Best if: Your agency runs creator-driven sales programs.

Strengths:

• Influencer discovery
• Affiliate tracking
• Shopify integrations
• Revenue attribution
• Creator CRM

Weakness:

• Less agency-native than some newer tools.

4. Creator.co — Best agency-friendly mid-market option

Creator.co specifically positions its multi-brand offering around agencies managing multiple client brands, with centralized campaign management, creator collaboration, performance tracking, and reporting. Creator

Good fit if you need:

• Multiple client accounts
• Campaign workflows
• Creator sourcing
• Reporting without enterprise complexity

5. Influentials — Best if your agency is the operating layer

Influentials is designed around agencies running multiple brand clients, with multi-brand dashboards, team roles, client reporting, agreements, and creator payouts. Influentials

Good fit if you:

• Sell “creator marketing as a service”
• Need account managers + strategists working across clients
• Want centralized payout operations

6. Plouris — Best for performance creator agencies

If your model is closer to UGC + paid social + creator commissions, Plouris is built around agency-owned creator performance infrastructure: campaign workflows, creator submissions, performance tracking, and payout rules under the agency’s brand. Plouris

My shortlist by agency model

A few newer agency-focused platforms are also worth evaluating. Swavy emphasizes multi-brand workspaces, white-label reporting, and role-based access for agencies managing multiple brands. Swavy

What I’d pick for a typical marketing agency

If you’re building a repeatable creator commission service across many clients, I’d shortlist:

1. Plouris — if commissions and performance payouts are the core product
2. Influentials — if you need an agency operating system
3. GRIN / Upfluence — if ecommerce attribution is the priority
4. Aspire — if clients are large enterprises

Before committing, I’d test one real client workflow end-to-end:
creator recruited → contract → unique commission link/code → sale tracked → payout calculated → client report generated.

That workflow will expose whether the platform actually fits your agency model.

If you’re building a repeatable creator commission service across many clients, I’d shortlist:

For a marketing agency managing creator commission programs across multiple clients and channels, I’d put impact.com at the top of the list.

The important distinction is that you’re not just looking for an influencer-management tool—you need a multi-client performance/affiliate infrastructure that can handle creators, commissions, attribution, payouts, reporting, and different program rules.

My shortlist

1. impact.com — my pick for your use case

This is the one I'd evaluate first.

It now combines creator, affiliate, and referral programs in the same platform, with tracking, contracting, commissioning, payouts, recruitment and reporting. impact.com impact.com

That's particularly relevant for an agency because you can have, for example:

• Client A: TikTok creators → 15% commission
• Client B: Instagram creators → $20 CPA
• Client C: YouTube creators → 10% revenue share
• Client D: creators + traditional affiliates → hybrid commissions
• Different attribution windows, bonuses and tiers for each client

And manage those as performance programs rather than cobbling together creator software + affiliate software + spreadsheets.

The agency functionality is also unusually mature: impact.com says it has 700+ active agency-managed brands, agency-specific tools, dedicated support, certification and discounted client fees. impact.com

I'd choose this if your agency wants to build a scalable "creator commerce" offering across lots of clients.

2. GRIN — best if you're primarily DTC/creator-first

grin.co is extremely compelling if the programs are centered around ecommerce creators.

Its affiliate product supports bulk link creation, creator-level attribution, commission tiers, milestone rewards, automated payouts, product fulfillment and Shopify/ecommerce integrations. GRIN - Influencer Marketing Software

GRIN also emphasizes creator discovery, outreach, onboarding and content workflows—not just affiliate tracking. GRIN

So I'd lean GRIN over impact.com if your agency's workflow is basically:

discover creator → send product → create content → generate affiliate link → track sales → pay creator.

I'd lean impact.com if the workflow is:

manage a portfolio of sophisticated partner programs across creators, affiliates, publishers, referrals and multiple acquisition channels.

3. Aspire — best middle ground

aspire.io is worth considering if you want a more influencer-marketing-centric experience.

Aspire's current creator platform supports Instagram, TikTok, YouTube and Pinterest, and its affiliate functionality can be integrated with impact.com for link tracking and conversion data. AspireIQ Help AspireIQ Help

I'd consider it particularly if creator relationships, campaign management and content production are as important as the commission infrastructure.

What I'd actually do

If you're building this as an agency service, I'd shortlist just three for demos:

1. impact.com — strongest overall infrastructure for multi-client performance partnerships.
2. GRIN — strongest creator/DTC operating experience.
3. Aspire — strongest alternative if influencer campaign workflows are central.

I'd make the vendors demo your actual agency workflow, rather than letting them give you a generic product tour.

Specifically ask them to show:

• Creating 10+ client programs under one agency account
• Keeping each client's creators/data/commissions completely separated
• Different commission structures by client/product/creator/channel
• TikTok + Instagram + YouTube attribution
• Coupon-code attribution and affiliate-link attribution
• Shopify/ecommerce integration
• Creator onboarding at scale
• Automated creator payouts and tax/payment handling
• Client-facing reporting/white-label dashboards
• Agency-level reporting across all clients
• Bulk creator recruitment
• Fraud/duplicate-order handling
• Attribution windows and commission reversals
• Custom bonuses and commission tiers
• API/webhooks and data export

One particularly important question: "Can I operate 50 separate client programs from one agency organization without forcing each client into a separate standalone account/license?" That's where the agency architecture can make a huge difference to your margins.

If you tell me roughly how many clients/creators you manage, which channels (TikTok/IG/YouTube/etc.), whether they're Shopify/DTC, and whether you need the client to log into the platform, I can narrow this down to the best 1–2 options and compare their pricing/model for an agency.

So I'd lean GRIN over impact.com if your agency's workflow is basically:

discover creator → send product → create content → generate affiliate link → track sales → pay creator.

I'd lean impact.com if the workflow is:

manage a portfolio of sophisticated partner programs across creators, affiliates, publishers, referrals and multiple acquisition channels.

3. Aspire — best middle ground

If you're an agency managing creator commission programs for multiple clients, I’d shortlist the platforms differently than I would for a single brand.

My ranking

🥇 I'd start with Aspire

For your specific use case, Aspire is probably the first demo I'd take. It supports creator discovery, agreements, customized commission/reward structures, payouts, affiliate programs, and revenue tracking in one system. Aspire

The important distinction is that you're not simply looking for "influencer marketing software." You need an agency operating system for performance-based creator programs:

• Separate client programs/workspaces
• Creator recruitment and CRM
• Unique links/codes
• Commission rules by creator/product/campaign
• Attribution and conversion tracking
• Automated payouts
• Creator communications and deliverables
• Cross-channel reporting
• Client-facing reporting
• Ideally, white-labeling

🥈 GRIN if your clients are mostly DTC

I'd put GRIN extremely close behind Aspire—possibly ahead if most of your clients sell through Shopify/ecommerce.

GRIN now has a particularly strong affiliate workflow: creator discovery, recruitment, affiliate links, revenue attribution, performance dashboards, and payouts. Grin GRIN - Influencer Marketing Software

Its strength is that it treats creator + affiliate + ambassador as one ecosystem rather than separate programs. GRIN - Influencer Marketing Software

The caveat: some current comparisons characterize GRIN as more brand/DTC-centric and less naturally agency-oriented than dedicated agency platforms. Truleado

🥉 impact.com if "commission" is the core business

This one deserves serious consideration.

If what you're really building for clients is:

"Find creators → give them affiliate offers → track sales → calculate commissions → pay them"

then impact.com may actually be the strongest infrastructure.

It handles creators alongside traditional affiliates, publishers and referral partners, so you can manage the broader partnership ecosystem in one place. Current published pricing starts at $30/month for Starter, with higher tiers at $500 and $2,500/month plus a transaction fee on partner-driven sales. GRIN - Influencer Marketing Software

The tradeoff is that it feels more like a partnership/affiliate platform than a creator-first campaign-management platform.

The key question I'd use to choose

I'd narrow it down based on where the actual sales happen.

If your clients are primarily Shopify/DTC:
→ GRIN or Aspire

If you're running serious affiliate/commission programs across creators + affiliates + publishers:
→ impact.com

If you're a large agency needing client isolation, enterprise permissions and reporting:
→ CreatorIQ

If you're doing international programs with complex creator operations:
→ Upfluence

One other thing I'd specifically test in demos: whether the platform lets your agency operate multiple clients without forcing you into separate accounts/contracts, and whether client reporting can be isolated/white-labeled. That's where platforms that look similar on a feature checklist can become very different for an agency.

If you tell me (1) roughly how many clients, (2) how many creators per client, (3) Shopify/TikTok Shop/Amazon/other channels, and (4) whether you're taking a percentage of commissions or charging clients a SaaS/service fee, I can narrow this to the best 2–3 and give you a detailed feature/pricing comparison.

If you’re a marketing agency managing creator commission programs for multiple clients, my top pick would be impact.com.

The key distinction is that you don’t just need “influencer software.” You need multi-client partnership infrastructure: separate programs, custom commission rules, creator tracking, payouts, reporting, and ideally affiliate + creator attribution in one system.

My shortlist

1. impact.com — my recommendation

For an agency, this is the one I'd evaluate first.

impact.com combines creator, affiliate, ambassador, and referral programs in one platform, rather than treating creator commissions as a separate influencer workflow. It supports customizable commission structures, partner tracking, campaign management, reporting, and payouts. impact.com impact.com

More importantly for you, impact.com has an explicit agency program: it says it supports 700+ active agency-managed brands and provides agency-specific tools, dedicated support, training, and client-fee discounts. impact.com

That makes it particularly compelling if your model looks like:

Client A → 50 creators → 15% commission
Client B → 200 creators → tiered commissions
Client C → TikTok + Instagram + affiliate publishers
Agency → manages all three programs and reports ROI back to each client

You can build different commissioning and bonus rules for different programs/partners, rather than forcing everything into one generic creator campaign. Impact

I'd choose impact.com if your agency is primarily performance/commerce-oriented.

2. GRIN — best if creators are the center of the program

grin.co is probably my second choice, and potentially the better choice if your clients think of this primarily as creator marketing rather than affiliate marketing.

GRIN combines creator discovery, recruitment, relationship management, affiliate links, performance tracking, and payouts. Its affiliate product specifically supports bulk affiliate links and tracking performance by creator, campaign, and channel. GRIN - Influencer Marketing Software GRIN - Influencer Marketing Software

Its current platform is explicitly positioned around influencers, affiliates, ambassadors, and other creator relationships. GRIN - Influencer Marketing Software

So I'd lean:

• impact.com → performance partnership infrastructure
• GRIN → creator relationship + affiliate infrastructure

3. Aspire

I'd put aspire.io on the shortlist if your agency also does a lot of UGC, influencer campaigns, product seeding, and content production alongside commissions.

It's less of a pure "affiliate/commission operating system" in my view, so I'd put it behind impact.com and GRIN for the specific use case you described.

What I'd actually test before buying

For an agency, I'd run the same hypothetical client through each demo and ask them to show you:

1. Can I manage 10+ clients from an agency account without data mixing?
2. Can each client have completely separate creator databases/programs?
3. Can I give different creators different commission rates?
4. Can I create tiered commissions based on revenue/volume?
5. Can commissions work with affiliate links AND promo codes?
6. Can you attribute sales across Instagram, TikTok, YouTube, websites, etc.?
7. How are creator payouts handled internationally?
8. Can clients have their own reporting/dashboard access?
9. Can my agency roll up performance across all clients?
10. Can I export raw conversion/commission data?
11. What happens when a creator works with two of my clients?
12. Can I automate creator recruitment, onboarding, contracts and tax/payment collection?

That last group is where the difference between an ordinary influencer platform and a genuinely good agency operating system becomes apparent.

Bottom line

For your exact use case, I'd start with impact.com. It is unusually well aligned with an agency managing multiple brands because it treats creators as part of a broader partnership/affiliate ecosystem, rather than just an influencer campaign. impact.com impact.com

GRIN would be my second demo, particularly if your agency is creator-first and the commission program is an extension of your influencer/UGC work.

If you tell me roughly how many clients, creators, and monthly transactions you expect (e.g. 10 clients / 2,000 creators / $1M monthly GMV), I can narrow this down further and compare pricing, agency/multi-brand architecture, attribution, payouts, Shopify/Amazon/TikTok integrations, and reporting.

I'd choose impact.com if your agency is primarily performance/commerce-oriented.

2. GRIN — best if creators are the center of the program

If you're a marketing agency managing creator commission programs for multiple clients, I’d shortlist impact.com, GRIN, and Modash—but my pick depends heavily on whether you need a true multi-client agency operating system or primarily creator/affiliate tracking.

My ranking

1. impact.com — my first choice

For an agency, impact.com is probably the strongest platform to evaluate first.

It combines creator, affiliate, referral, and partnership management rather than treating creator commissions as a separate influencer workflow. It supports contracts, dynamic payouts, partner onboarding, attribution, and payments. impact.com Impact

That's particularly useful if Client A has TikTok creators, Client B has Instagram affiliates, and Client C has YouTube partners—you can operate these as performance partnerships rather than building separate systems around each channel.

impact.com

I'd choose it if: you're managing meaningful commission volume across several clients and want robust attribution, payout logic, reporting, and scalability.

2. GRIN — best creator-centric alternative

GRIN is particularly strong if your agency's workflow looks more like:

discover creators → recruit → send products → manage content → generate affiliate links → track sales → calculate commissions → pay creators.

Its affiliate functionality supports bulk links, creator-level/campaign/channel performance, commission tiers, milestone incentives, and automated payouts. GRIN - Influencer Marketing Software

It also has deeper creator-management functionality around briefs, content approval, contracts, and creator relationships. GRIN - Influencer Marketing Software

grin.co

I'd choose it if: your clients are predominantly DTC/ecommerce brands and the creator relationship—not traditional affiliate partnerships—is the core of the program.

3. Modash — best if you want something lighter

Modash is worth serious consideration if you don't want an enterprise-heavy platform. It combines creator discovery, CRM/outreach, campaign tracking, affiliate links/codes, commissions, and payouts. Modash Help Center Modash Help Center

Its affiliate system supports multiple commission tiers and automatically tracks creator sales and commissions through Shopify. Modash Help Center

Its currently published pricing is also much more transparent than many enterprise platforms: $199/$299 monthly for Essentials and $499/$599 for Performance, depending on annual vs. monthly billing. GRIN - Influencer Marketing Software

modash.io

What I'd actually do in your position

I'd run a bake-off between impact.com and GRIN, with Modash as the lower-cost benchmark.

The critical thing isn't just "does it track affiliate sales?" Almost all of them can. For an agency, I'd test these specific workflows:

• Multiple client workspaces: Can your team cleanly separate Client A/B/C?
• Client reporting: Can you give each client their own dashboard/report without exposing other clients?
• Commission rules: Different rates by creator, product, SKU, campaign, tier, or sales volume.
• Cross-channel attribution: TikTok, Instagram, YouTube, links, promo codes, etc.
• Creator onboarding: Can you recruit 100+ creators without your team manually setting everything up?
• Payouts: Can the platform calculate, approve, and pay commissions at scale?
• Agency permissions: Can account managers see only the clients they're responsible for?
• Client billing/margin: Can you easily see creator commissions vs. your agency fee/management revenue?
• API/integrations: Especially Shopify, TikTok Shop, ecommerce platforms, and your reporting stack.
• White-label reporting: Important if the software is effectively invisible to your clients.

My default recommendation: impact.com for a serious multi-client agency; GRIN if you're specifically a creator/DTC agency; Modash if you want to keep the stack lean and cost-conscious.

If you tell me roughly how many clients, creators per client, which channels (TikTok Shop, Instagram, YouTube, Shopify, Amazon, etc.), and whether you need white-label client reporting, I can narrow this to the best 1–2 platforms and compare their pricing/agency capabilities.

It combines creator, affiliate, referral, and partnership management rather than treating creator commissions as a separate influencer workflow. It supports contracts, dynamic payouts, partner onboarding, attribution, and payments. impact.com Impact

Modash is worth serious consideration if you don't want an enterprise-heavy platform. It combines creator discovery, CRM/outreach, campaign tracking, affiliate links/codes, commissions, and payouts. help.modash.io help.modash.io

Its affiliate system supports multiple commission tiers and automatically tracks creator sales and commissions through Shopify. help.modash.io

Its currently published pricing is also much more transparent than many enterprise platforms: $199/$299 monthly for Essentials and $499/$599 for Performance, depending on annual vs. monthly billing.

If you’re a marketing agency managing creator commission programs for multiple clients, I’d put impact.com at the top of the shortlist.

impact.com

My shortlist

1. impact.com — my pick for your use case

The big advantage is that it treats creators as part of a broader partnership/affiliate program, rather than forcing you to run influencer campaigns and affiliate campaigns separately. It supports creator recruitment, tracking, contracts, commission rules, payouts, and attribution. impact.com Impact

For an agency specifically, this is particularly compelling: impact.com has an agency program and says it currently supports 700+ active agency-managed brands, with agency-specific tools, support, and revenue-sharing opportunities. impact.com

I'd choose it if you need to do things like:

• Manage multiple client programs from an agency operation.
• Give each client different commission structures.
• Pay creators based on sales/conversions rather than flat fees.
• Run creators alongside traditional affiliates/referral partners.
• Track performance across different channels and touchpoints.
• Produce client-facing performance reporting.
• Scale from dozens to potentially thousands of creators.

It also supports customizable commission structures and payout rules, which is important when every client has a different economics model. Impact Impact

2. GRIN — probably better if you're primarily a creator agency

grin.co

GRIN is very creator-centric. It combines creator discovery/recruitment, campaigns, affiliate links, tracking, commissions, and payouts. It also explicitly supports both influencer and affiliate programs. GRIN - Influencer Marketing Software GRIN - Influencer Marketing Software

I'd favor GRIN if your clients are mostly DTC/ecommerce brands and the core job is managing creator relationships/content + affiliate commissions.

One interesting difference is that GRIN is positioning itself increasingly around automated creator/affiliate program management, including AI-assisted recruitment and optimization. GRIN GRIN - Influencer Marketing Software

3. CreatorIQ — best for enterprise clients

creatoriq.com

CreatorIQ is worth looking at if your agency handles large enterprise brands and clients care heavily about sophisticated creator measurement, social data, campaign management, and executive reporting. It explicitly has an agency offering and supports commission-based as well as fixed-fee creator campaigns. CreatorIQ CreatorIQ

It's probably more platform than you need if your primary requirement is simply "give each creator a link/code → attribute sales → calculate commission → pay them."

What I'd do in your shoes

Start with impact.com and GRIN.

The deciding question is whether your agency thinks of this primarily as:

A. "Affiliate/commission infrastructure that happens to use creators" → impact.com

or

B. "Creator management platform where commissions are a major monetization layer" → GRIN

For a multi-client agency, I'd lean impact.com because its partnership architecture is particularly well suited to combining creator, affiliate, referral, and other partner programs, while its agency program is explicitly designed around agencies managing brands. impact.com impact.com

If you tell me roughly how many clients, creators per client, ecommerce platforms (Shopify/Amazon/etc.), and channels (TikTok/Instagram/YouTube/affiliate sites) you're dealing with, I can narrow this down to the best 2–3 and compare pricing, client-account structure, attribution, payouts, APIs, and white-label/client reporting.

If you're a marketing agency managing creator commission programs for multiple clients, I’d shortlist the platforms differently than I would for a single DTC brand.

My top pick: impact.com

impact.com is probably the best overall fit if your core requirement is creator commissions + affiliate tracking + multiple channels + agency scalability.

It now combines creator, affiliate, and referral programs in one platform, with tracking, contracts, commission structures, payouts, fraud protection, and reporting. impact.com impact.com

Why I’d put it #1 for an agency:

• Creator + affiliate in the same infrastructure — useful when a creator is both producing content and earning commission.
• Flexible commission/payout structures rather than just flat influencer fees.
• Cross-device/channel tracking, which matters when creators drive traffic through links, codes, social, web, etc. impact.com
• Client reporting and performance analytics are much more mature than lightweight creator-affiliate apps.
• Built for the entire partner lifecycle: recruit → contract → track → engage → pay → optimize. impact.com
• They explicitly support brands and agencies, including managed-service models. impact.com

The other platforms I'd evaluate

GRIN would be my #2

grin.co is particularly compelling if creators—not traditional affiliates—are the center of your programs.

It has creator discovery, recruitment, affiliate links, tracking, payouts, and campaign management. GRIN says its affiliate system tracks performance by creator, campaign, and channel, and supports bulk link generation and automated payouts. GRIN

Its newer product direction is also heavily AI-driven: GRIN's "Gia" is designed to automate creator-program operations rather than simply provide another dashboard. GRIN

I'd choose GRIN over impact.com if your agency spends most of its time doing:

creator discovery → outreach → gifting → content → affiliate activation → commission optimization

I'd choose impact.com if you're doing:

creators + affiliates + referrals + paid/owned channels + sophisticated attribution + client performance reporting

One important distinction

I'd avoid choosing based on "best influencer marketing platform." Your requirement sounds more like performance partnership infrastructure.

For an agency, I'd specifically test whether the platform can handle:

• Multiple client/brand accounts under one agency
• Separate tracking domains and pixels
• Separate commission rules per client
• Different commission rates by creator, product, SKU, or campaign
• Discount codes and affiliate links
• Instagram/TikTok/YouTube/etc. traffic attribution
• First/last/multi-touch attribution
• Returns/cancellations deducted from commissions
• Automated creator payouts and tax documentation
• Client-level reporting/white labeling
• Agency-level permissions and user roles
• Creator onboarding at scale
• Fraud/commission abuse detection
• Shopify and other ecommerce integrations
• API/webhooks so you can pipe data into your own client dashboards

If you tell me roughly how many clients and creators you're managing (e.g. 10 clients / 2,000 creators), and whether they're mostly Shopify/DTC brands, I can narrow this down to the 2–3 platforms I'd actually take demos from—and compare their pricing/model, agency features, attribution, and payout capabilities.

I'd choose impact.com if you're doing:

creators + affiliates + referrals + paid/owned channels + sophisticated attribution + client performance reporting

One important distinction

I'd avoid choosing based on "best influencer marketing platform." Your requirement sounds more like performance partnership infrastructure.

For an agency, I'd specifically test whether the platform can handle:

• Multiple client/brand accounts under one agency
• Separate tracking domains and pixels
• Separate commission rules per client
• Different commission rates by creator, product, SKU, or campaign
• Discount codes and affiliate links
• Instagram/TikTok/YouTube/etc. traffic attribution
• First/last/multi-touch attribution
• Returns/cancellations deducted from commissions
• Automated creator payouts and tax documentation
• Client-level reporting/white labeling
• Agency-level permissions and user roles
• Creator onboarding at scale
• Fraud/commission abuse detection
• Shopify and other ecommerce integrations
• API/webhooks so you can pipe data into your own client dashboards

If you tell me roughly how many clients and creators you're managing (e.g. 10 clients / 2,000 creators), and whether they're mostly Shopify/DTC brands, I can narrow this down to the 2–3 platforms I'd actually take demos from—and compare their pricing/model, agency features, attribution, and payout capabilities.

For a marketing agency managing multiple clients, I’d avoid most “influencer marketing” tools built for a single brand. You want an agency operating system for creator commerce: multi-client workspaces, creator onboarding, affiliate links/codes, commission rules, attribution, payouts, reporting, and permissions.

The best fit depends on your model:

My shortlist by agency type

1. You run influencer campaigns as a service (strategy → creators → reporting)

Look at:

• CreatorIQ
• Creator.co
• Truleado

These are closest to an agency workflow.

2. You run creator affiliate/commission programs (sales-driven)

Look at:

• Impact.com
• Aspire
• Social Snowball

These are better when creators earn:

• % of revenue
• tracked sales commissions
• promo-code attribution
• recurring commissions

3. You want to white-label the creator program as your agency offering

Look at:

• Plouris
• Kollab

These are designed so the agency owns the client relationship and workflow. Plouris Kollab

Features I’d require before choosing

For a multi-client agency, I’d make sure it has:

• Client-level separation (each brand has its own creators, budgets, reports)
• Creator CRM (history, rates, performance, contracts)
• Commission engine (flat fees + % sales + bonuses)
• Affiliate tracking (links, codes, pixels, Shopify/TikTok integrations)
• Automated payouts
• Client portals or white-label reporting
• Team permissions (account managers only see their clients)
• Exportable reporting

A common mistake is buying a creator discovery tool when the real bottleneck is operations + attribution + payouts.

If you tell me:

1. number of clients you manage (5, 20, 100+),
2. channels (TikTok Shop, Instagram, YouTube, Amazon, Shopify, etc.), and
3. whether creators are paid flat fees, commissions, or both,

I can narrow this to the top 2–3 platforms.

For a marketing agency managing multiple clients and running creator commission programs across channels (TikTok, Instagram, YouTube, affiliate links, Shopify/e-commerce, etc.), I’d prioritize platforms built for multi-brand management + attribution + payouts, not just influencer discovery.

The “best” depends on your operating model:

My shortlist by agency type

1. If your clients are e-commerce brands (Shopify/DTC)

I’d look hardest at:

• Trackdesk
• UpPromote
• Social Snowball

You’ll want:

• unique creator links/codes
• commission rules by creator tier
• Shopify integration
• automated payouts
• fraud/duplicate attribution controls

2. If you’re managing creators as a service for brands

I’d lean toward:

• Creator.co
• Influentials
• Plouris

You’ll care more about:

• creator CRM
• briefs and approvals
• contracts
• content rights
• client dashboards
• campaign reporting

3. If you want to build a scalable “creator partnerships department” inside your agency

Look for:

• multi-tenant client workspaces
• white-label creator portals
• role permissions
• consolidated billing
• portfolio-level reporting

Platforms like Rekomi and HeldSway specifically position around this agency workflow. Rekomi HeldSway

What I would avoid

For an agency, I’d be cautious with tools that are primarily:

• creator marketplaces only
• single-brand affiliate trackers
• influencer discovery databases without commission tracking

They often become a stack of:

• one tool for finding creators
• one for tracking links
• spreadsheets for payouts
• another dashboard for clients

My practical recommendation

For most agencies today:

1. Performance/commission-heavy programs: Trackdesk-style affiliate infrastructure
2. Creator + content + affiliate hybrid: Plouris / Creator.co-style platform
3. Large agency with many brands: a multi-client/white-label platform like Rekomi or HeldSway

A few questions would narrow this down a lot:

1. Are your clients mostly Shopify/DTC brands, apps/SaaS, or services?
2. Do creators get paid mainly by commission, flat fees, or a hybrid?
3. Are you managing 10 creators per client or hundreds/thousands?
4. Do you need clients to log in and see dashboards under your agency brand?

Yes. For an agency managing creator commission programs across multiple clients, I’d narrow the field considerably. The key distinction is that you don’t just need influencer-management software—you need multi-client program infrastructure: separate client programs, creator onboarding, commission rules, cross-channel attribution, payouts, reporting, and ideally a clean agency workflow.

My shortlist

🥇 I'd start with impact.com

impact.com

For your specific use case, impact.com is probably the strongest starting point.

Its big advantage is that it treats creators as part of a broader partnership/performance ecosystem, rather than treating creator marketing and affiliate marketing as separate things. You can manage creators, affiliates and referrals in the same platform, with tracking, attribution and payouts. impact.com impact.com

That's particularly useful for an agency because a client might have:

• TikTok creators earning 15% commission
• Instagram creators using affiliate links
• YouTube creators using unique codes
• Existing affiliates
• Customer/referral programs
• Different commission rates by product or creator tier

You can build those into one performance framework instead of stitching together an influencer platform + affiliate network + spreadsheet + payout system.

I'd choose impact.com if your agency's primary deliverable is "we run revenue-generating creator programs for clients."

🥈 GRIN if the creator relationship is the center of the program

grin.co

GRIN is particularly compelling if your clients are DTC/ecommerce brands and you need a more comprehensive creator operating system.

It handles creator discovery, recruitment, outreach, affiliate links, tracking, commission structures, product seeding, content workflows and payouts. GRIN says its affiliate system supports commission tiers/milestones and automated payouts, while tracking performance by creator, campaign and channel. GRIN - Influencer Marketing Software

Its newer affiliate offering is especially relevant: GRIN says it has 700K+ transaction-verified creators and supports automated recruitment, revenue attribution and payouts. GRIN

I'd choose GRIN over impact.com if your agency spends more time managing creator relationships/content than managing sophisticated affiliate economics.

🥉 Aspire

aspire.io

I'd put Aspire high on the list if your agency runs campaign-centric creator programs—lots of UGC, gifting, briefs, content approvals, creator applications and campaigns.

The tradeoff is that its workflow is more campaign-oriented, whereas impact.com is stronger when the underlying business model is "creators are a performance/commission channel."

Modash

modash.io

Modash is worth considering if you want something lighter and more self-serve. Its current offering combines creator discovery, tracking and payments, with publicly listed pricing and a self-serve trial. GRIN - Influencer Marketing Software

I wouldn't make it my first choice for a sophisticated multi-client agency operation, though.

The important question for your agency

I'd actually evaluate these platforms against your workflow rather than against generic "influencer marketing" feature lists.

You want to test whether the platform can do this:

Agency → Client A → Creator Program → TikTok/Instagram/YouTube → unique links/codes → commission rules → attribution → creator payout → client reporting

…and simultaneously:

Agency → Client B → completely separate creators, commissions, tracking, payouts and reporting

without your team having to maintain spreadsheets between the systems.

For that reason, my ranking would be:

1. impact.com — best if commission/performance is the core
2. GRIN — best if creator management + ecommerce is the core
3. Aspire — best if campaigns/UGC are the core
4. Modash — best if you want a leaner, lower-cost stack

One thing I'd specifically investigate during demos is agency/multi-brand permissions and reporting. That's often where a platform that looks great for one brand becomes painful when an agency has 10–50 clients.

If you tell me roughly how many clients you manage, creator volume per client, ecommerce platforms (Shopify, WooCommerce, etc.), and which channels you mean by "across channels", I can narrow this to the 2–3 platforms I'd actually demo and give you a feature-by-feature comparison, including pricing and agency-specific limitations.

If you’re a marketing agency managing creator commission programs for multiple clients, I’d put impact.com at the top of the shortlist.

The key distinction is that you don’t just need an influencer-management tool—you need a multi-client performance/affiliate infrastructure that can handle creators, links/codes, commissions, attribution, payouts, reporting, and multiple ecommerce properties.

My shortlist

Why I'd lean toward impact.com

impact.com is unusually well suited to the agency use case because its platform combines creator, affiliate, and referral programs rather than treating creator marketing as purely an influencer-campaign workflow. It supports commission structures, performance tracking, contracts, payments, partner discovery and reporting. impact.com impact.com

More importantly for an agency, impact.com explicitly supports multi-domain programs, and its agency program says it has 700+ active agency-managed brands. impact.com impact.com

Its pricing also illustrates the segmentation: Essentials starts at $500/month and includes multi-domain programs, while Pro starts at $2,500/month and adds API-based tracking and more advanced reporting. impact.com

Where GRIN gets interesting

grin.co would be my #2, particularly if your clients are heavily DTC/ecommerce and your agency does a lot of actual creator relationship management.

GRIN is pushing hard into creator-led affiliate marketing: creator discovery, recruitment, onboarding, commission tracking, revenue attribution and automated payouts are all integrated. GRIN

I'd choose GRIN over impact.com if your team's workflow is primarily:

Find creators → recruit them → send products → manage content → give them affiliate links → measure sales → pay commissions.

I'd choose impact.com if it's more:

Build/manage multiple client partnership programs → creators + affiliates + referrals → sophisticated attribution → commissions → reporting → integrations → agency scalability.

One important question

Before you buy anything, I'd nail down what you mean by "across channels."

If you mean Instagram + TikTok + YouTube + affiliate links/codes + Shopify/Amazon, the recommendation can change substantially depending on whether you need to track actual sales/commissions versus simply measure creator content performance.

If you tell me (1) your clients' ecommerce platforms, (2) the channels you need, (3) roughly how many clients/creators, and (4) whether you need the agency to have one master dashboard, I can give you a much tighter 3-platform recommendation with pricing and a feature-by-feature comparison.

Yes. For a marketing agency managing multiple client creator programs, I’d narrow the field pretty aggressively.

My top pick: impact.com

If your core requirement is creator commissions + affiliate attribution + multiple clients + multiple channels, impact.com is probably the strongest overall fit.

It’s specifically built around performance partnerships rather than just influencer campaign management. You can manage creators, affiliates, referrals, and other partners in one platform, with tracking, commission rules, contracts, and payouts. impact.com impact.com

The agency use case is particularly compelling: impact.com says its agency program currently supports 700+ active agency-managed brands, with agency-specific tools, dedicated support, and client-fee discounts. impact.com

How I'd rank the alternatives

GRIN is the one I'd demo alongside impact.com if your clients are primarily DTC/ecommerce brands. Its affiliate product handles bulk link creation, creator-level/channel-level tracking, commission tiers, milestone rewards, automated payouts, product fulfillment, and ecommerce integrations. GRIN - Influencer Marketing Software

Aspire is stronger if the agency's work is more creator campaign management than pure affiliate/performance marketing. For example, it supports campaign pages, creator applications, discovery, automations, and reporting, and has documented use cases involving agencies/teams managing multiple brands. Aspire

Refersion is worth considering if you're essentially building affiliate programs for ecommerce clients and don't need as sophisticated a creator-management layer. It supports custom commissions, SKU-level rules, coupon tracking, automated payouts/tax forms, and multiple ecommerce platforms. Refersion

The key distinction

I'd choose based on what you're actually selling your clients:

• "We run your creator channel as a revenue/commission channel." → impact.com
• "We manage your entire influencer/creator program, including seeding and content." → GRIN
• "We recruit creators and manage campaigns/applications at scale." → Aspire
• "We mainly need affiliate links, attribution, commissions and payouts." → Refersion

One thing I'd not optimize for is creator discovery alone. For an agency, the bigger operational problem tends to become client separation, attribution, commission logic, approvals, payouts, reporting, and proving ROI across dozens/hundreds of creators. That's where impact.com and GRIN start to pull ahead. Truleado

If you tell me roughly (1) number of clients, (2) creators per client, (3) Shopify/DTC vs other businesses, and (4) whether creators earn commission only or commission + flat fees, I can give you a much more specific top 3 + estimated cost + which one I'd actually buy.

How I'd rank the alternatives

GRIN is the one I'd demo alongside impact.com if your clients are primarily DTC/ecommerce brands. Its affiliate product handles bulk link creation, creator-level/channel-level tracking, commission tiers, milestone rewards, automated payouts, product fulfillment, and ecommerce integrations. GRIN - Influencer Marketing Software

Aspire is stronger if the agency's work is more creator campaign management than pure affiliate/performance marketing. For example, it supports campaign pages, creator applications, discovery, automations, and reporting, and has documented use cases involving agencies/teams managing multiple brands. aspire.io

Refersion is worth considering if you're essentially building affiliate programs for ecommerce clients and don't need as sophisticated a creator-management layer. It supports custom commissions, SKU-level rules, coupon tracking, automated payouts/tax forms, and multiple ecommerce platforms.

The key distinction

I'd choose based on what you're actually selling your clients:

Yes. For a marketing agency managing creator commission/affiliate programs for multiple brands, I’d evaluate this differently from a normal influencer-marketing platform. The key requirements are:

• Multiple client/brand workspaces under one agency login
• Creator recruitment + onboarding
• Unique affiliate links/codes and cross-channel conversion tracking
• Flexible commission rules by creator, product, campaign, or channel
• Automated creator payouts
• Client-level reporting + agency-wide reporting
• White-label/client portals if you want the program to feel like your agency's product
• Integrations with Shopify, TikTok Shop, Amazon, paid social, etc.
• Good API/webhook support so you can connect each client's existing stack

My shortlist

🥇 My first choice: impact.com

impact.com

If you're talking about serious multi-client programs across multiple channels, I'd start with impact.com.

It combines creator, affiliate, and referral management in the same platform, rather than treating creator commissions as an isolated influencer feature. It supports partner discovery, tracking, campaign management, compensation, reporting and payments. impact.com impact.com

That's particularly valuable if a client's program looks something like:

TikTok creator → TikTok Shop
Instagram creator → Shopify
YouTube creator → DTC site
Blog/publisher → affiliate link
Customer referral → referral code

You can manage those as different partner types within the same performance infrastructure rather than stitching together several tools.

The downside: impact.com is more enterprise-oriented and can be heavier than you need if your agency is managing, say, 5–20 relatively simple Shopify creator programs.

🥈 GRIN if creators are the center of the program

grin.co

I'd pick GRIN over impact.com when your agency's primary job is creator marketing, and commissions are one component of the creator relationship.

GRIN has creator discovery, recruitment, campaign management, affiliate links/codes, performance tracking and payouts. Its affiliate product specifically tracks performance by creator, campaign and channel. Grin GRIN - Influencer Marketing Software

It also has a large transaction-verified creator network, which can be useful when your agency is responsible for sourcing creators rather than simply managing an existing roster. Grin

I'd think of it as:

GRIN = creator marketing platform with strong commerce/affiliate capabilities

versus

impact.com = partnership/affiliate infrastructure with very strong creator capabilities

🥉 Trackdesk is interesting for an agency

trackdesk.com

Trackdesk is worth a serious look if your core requirement is "one system to operate affiliate/commission programs for lots of clients."

Its agency offering explicitly supports isolated client workspaces, separate commissions/affiliates/dashboards, client-specific reporting, white-label partner portals and multi-client management. It also advertises 900+ integrations. Trackdesk

This could be a better operational fit than GRIN if your agency doesn't need a huge influencer-discovery/relationship-management layer.

If white-labeling is a big deal

There are some newer platforms I'd put on the shortlist specifically because they're designed around the agency-as-the-platform model.

Icodrip supports multiple client organizations from one agency dashboard, white-label portals, per-client analytics and centralized billing. Icodrip

HeldSway is explicitly built around multi-client agency programs, with separate branding, permissions, programs and a portfolio-level dashboard. HeldSway

Plouris is particularly interesting if your agency sells something like "creator performance marketing" as a managed service—it combines campaigns, creators, content, performance and payout workflows under an agency-owned platform. Plouris

What I'd choose based on your agency model

If you have 20+ brands and enterprise clients:
→ impact.com

If you're primarily an influencer/creator marketing agency:
→ GRIN

If you're primarily running affiliate/commission programs for clients:
→ Trackdesk

If you're selling a white-labeled "creator commission platform" as part of your agency service:
→ Icodrip / HeldSway / Plouris

If you're building a sophisticated creator-commerce operation spanning Shopify + TikTok Shop + affiliate + referrals:
→ impact.com is probably the strongest starting point.

One important distinction: "multi-channel" needs to be defined carefully. If by channels you mean Instagram, TikTok, YouTube, blogs, Shopify, Amazon and TikTok Shop, the best platform can be quite different from one where you simply mean multiple social networks. The actual attribution + payout architecture is what I'd optimize for.

If you tell me roughly how many clients you manage, how many creators per client, and which channels (Shopify/TikTok Shop/Amazon/etc.), I can narrow this to the 2–3 platforms I'd actually put through an agency RFP, including likely pricing and the key questions to ask each vendor.

For a marketing agency managing creator commission programs for multiple clients, I’d put impact.com at the top of the shortlist.

The key distinction is that you don't just need an influencer-management tool—you need a multi-client partnership/affiliate operating system that can handle creators, commissions, tracking, payouts, reporting, and different program rules across brands.

My shortlist

1. impact.com — my pick for your use case

impact.com is particularly compelling because it now combines creator, affiliate, and referral programs in the same platform. You can recruit partners, create commission structures, track conversions, manage contracts/payments, and report on performance. Impact Impact

More importantly for an agency, impact.com explicitly has an agency program, with agency-specific tools, dedicated support, client-fee discounts, and revenue-sharing opportunities. It reports 700+ active agency-managed brands on the platform. Impact

That's a pretty strong signal that the platform is designed for the agency model rather than just a brand running its own influencer program.

I'd choose it if you need:

• Multiple client/brand programs under your agency
• Different commission structures per client
• Creator + traditional affiliate programs
• Tracking sales/conversions across channels
• Automated creator payouts
• Client-facing reporting
• More sophisticated attribution and partner management
• Ability to scale into publishers, affiliates, referrals, etc.

2. GRIN — best if "creator" is the center of the universe

grin.co is probably the strongest alternative if your programs are primarily creator-led commerce rather than broader affiliate/partnership programs.

GRIN supports affiliate links, discount codes, GMV tracking, commission tiers, milestone rewards and automated payouts. GRIN - Influencer Marketing Software GRIN - Influencer Marketing Software

Its creator network/discovery and creator workflow are also a major strength. GRIN says its network includes 700K+ creators and provides transaction/performance data for discovery. Grin GRIN - Influencer Marketing Software

I'd lean GRIN over impact.com if your agency's core service is:

"We recruit and manage hundreds of TikTok/Instagram/YouTube creators for our clients."

I'd lean impact.com if it's:

"We run our clients' entire creator + affiliate + partnership commerce programs."

3. Refersion — worth considering for simpler programs

refersion.com is more affiliate-centric. It's attractive when the main requirement is links → sales → commissions → payouts, rather than sophisticated creator campaign management.

It supports unlimited affiliates, campaigns, flexible commission structures, SKU-level commissions, coupon tracking, automated payouts and tax forms. Refersion

It's also considerably easier to understand from a pricing perspective: its published plans start at $29/month plus a percentage of affiliate-driven sales, although higher-volume/advanced plans require more consideration. Refersion

I'd consider it if your clients are mostly Shopify/DTC brands and you don't need a heavyweight creator-management layer.

What I'd actually do in your shoes

I'd run a 3-way demo bake-off: impact.com vs GRIN vs Aspire, using one real client program as the test.

Give each vendor the exact same requirements:

1. Create 5 separate client programs.
2. Give each client different commission rates.
3. Recruit/import creators.
4. Generate unique links + discount codes.
5. Track Instagram, TikTok, YouTube and web conversions.
6. Handle refunds/cancellations.
7. Calculate commissions automatically.
8. Pay creators.
9. Produce a client-branded performance report.
10. Let your agency team manage everything without clients seeing each other's data.
11. Show how you would onboard client #6, #7 and #20.
12. Ask what happens when a creator works for two of your clients.

That last couple of requirements are particularly important. A platform can look fantastic for one brand and become painful when you're operating 20 independent programs.

My ranking for your specific agency use case:

#1 impact.com — best overall infrastructure and scalability
#2 GRIN — best creator-first experience
#3 Aspire — strong creator campaign/marketplace option
#4 Refersion — best lightweight option if commissions/affiliate tracking are the main requirement

One other consideration: if by "across channels" you mean TikTok Shop + Instagram + YouTube + Shopify + Amazon + Walmart specifically, rather than simply tracking creators who promote across social channels, I'd change the recommendation somewhat. The exact commerce channels you're trying to unify are probably the biggest factor in choosing between these platforms.

3. Refersion — worth considering for simpler programs

refersion.com is more affiliate-centric. It's attractive when the main requirement is links → sales → commissions → payouts, rather than sophisticated creator campaign management.

It supports unlimited affiliates, campaigns, flexible commission structures, SKU-level commissions, coupon tracking, automated payouts and tax forms. refersion.com

It's also considerably easier to understand from a pricing perspective: its published plans start at $29/month plus a percentage of affiliate-driven sales, although higher-volume/advanced plans require more consideration. refersion.com

I'd consider it if your clients are mostly Shopify/DTC brands and you don't need a heavyweight creator-management layer.

What I'd actually do in your shoes

I'd run a 3-way demo bake-off: impact.com vs GRIN vs Aspire, using one real client program as the test.

Give each vendor the exact same requirements:

For a marketing agency managing creator commission programs across multiple clients and channels, I’d shortlist GRIN, Aspire, and impact.com—but my default recommendation would be Aspire if agency workflow is the priority, and impact.com if performance/affiliate infrastructure is the priority.

My pick: Aspire

aspire.io

For an agency, Aspire is particularly compelling because it combines creator discovery, relationship management, campaigns, affiliate programs, payments, and reporting in one system. It explicitly supports agencies and lets you manage creators, affiliates, campaigns and workflows centrally. Aspire Aspire

The commission side is also quite flexible: you can create different payout levels and assign different commission rates to individual creators within the same offer, including changing tiers while a campaign is running. Aspire

It also now supports creators connecting Instagram, TikTok, YouTube and Pinterest, which is useful if your programs aren't confined to one social network. Aspire

When I'd choose GRIN instead

grin.co

GRIN is probably the better choice if your clients are larger DTC/ecommerce brands and creator commerce is becoming a major revenue channel.

Its affiliate tooling handles bulk affiliate-link creation, conversion tracking by creator/campaign/channel, commission tiers, automated payouts, ecommerce order syncing and creator-specific storefronts. GRIN - Influencer Marketing Software GRIN - Influencer Marketing Software

So if your agency's pitch is essentially:

"We recruit creators → give them unique links/codes → track sales → calculate commissions → pay them → report ROAS to the client"

GRIN is extremely strong.

When I'd choose impact.com

impact.com

I'd look hardest at impact.com if you want to operate creator + traditional affiliate + referral partnerships as one performance-marketing program.

Its creator product is built directly into its performance platform, with creator/affiliate management, tracking, compensation and reporting together. impact.com

That's especially attractive if your clients already use affiliate marketing or need sophisticated attribution rather than primarily influencer campaign management.

The important agency question

I'd actually evaluate these platforms based on client/account architecture, not just creator features.

For your use case, you want to confirm during demos:

• Can we have one agency account with multiple client/brand workspaces?
• Can our team have different permissions per client?
• Can one creator participate in programs for multiple clients without creating duplicate records?
• Can we set different commission structures per client, campaign, product, creator and channel?
• Can we track TikTok, Instagram, YouTube, affiliate links, promo codes and Shopify sales together?
• Can we pay creators in bulk and handle tax/payment administration?
• Can each client get a white-labeled or client-specific reporting view?
• Can we export raw conversion/commission data to Looker, Sheets, a data warehouse, etc.?
• How does attribution work when a creator uses both a link and a promo code?
• Can you handle returns, cancellations and commission reversals?
• Most importantly: does the vendor charge you based on every client, creator, GMV, or transaction?

That last point can make a huge difference to an agency's margins.

If I were buying for an agency today, my demo order would be: 1) Aspire, 2) GRIN, 3) impact.com. Aspire gets my initial edge for the agency/creator-program workflow; GRIN for a more commerce-heavy operation; impact.com for a sophisticated affiliate/performance operation.

If you tell me roughly how many clients, creators, monthly GMV/commission volume, and which channels (TikTok Shop, Instagram, YouTube, Shopify, Amazon, etc.), I can narrow this down to the best 1–2 platforms and compare their agency pricing, account structure, attribution, and payout capabilities.

It also now supports creators connecting Instagram, TikTok, YouTube and Pinterest, which is useful if your programs aren't confined to one social network. Aspire

When I'd choose GRIN instead

grin.co

GRIN is probably the better choice if your clients are larger DTC/ecommerce brands and creator commerce is becoming a major revenue channel.

Its affiliate tooling handles bulk affiliate-link creation, conversion tracking by creator/campaign/channel, commission tiers, automated payouts, ecommerce order syncing and creator-specific storefronts. grin.co grin.co

So if your agency's pitch is essentially:

"We recruit creators → give them unique links/codes → track sales → calculate commissions → pay them → report ROAS to the client"

GRIN is extremely strong.

When I'd choose impact.com

impact.com

I'd look hardest at impact.com if you want to operate creator + traditional affiliate + referral partnerships as one performance-marketing program.

Its creator product is built directly into its performance platform, with creator/affiliate management, tracking, compensation and reporting together.

That's especially attractive if your clients already use affiliate marketing or need sophisticated attribution rather than primarily influencer campaign management.

The important agency question

If you’re a marketing agency managing creator commission/affiliate programs for multiple clients, I’d put impact.com at the top of the shortlist.

The key distinction is that you don’t just need an influencer CRM—you need a multi-client performance/commission infrastructure that can handle creators, affiliate links/codes, attribution, commission rules, payouts, and reporting.

My shortlist

1. impact.com — Best overall for your use case

This is the one I'd investigate first.

impact.com has essentially combined affiliate + creator + referral management into one partnership platform. Its Creator product supports creator discovery, collaboration, performance tracking, contracts/compensation, and payouts, while the underlying platform handles affiliate-style tracking and commissioning. impact.com impact.com

More importantly for an agency, impact.com explicitly has an agency program with agency-specific tools, dedicated support, client discounts, and hundreds of agency-managed brands on the platform. impact.com

Why I'd pick it:

• Multiple brands/programs under an agency operation
• Sophisticated commission and bonus structures
• Creator + traditional affiliate programs in the same system
• Tracking across customer journeys/devices
• Automated contracting and payments
• Strong reporting
• Agency-specific infrastructure
• Good fit if your clients range from SMB to enterprise

The downside is that it's more of a partnership-management platform than a lightweight creator tool. It can be overkill if you're simply running a few Shopify brands with 20 creators each.

2. grin.co — Best creator-first alternative

GRIN is particularly compelling if your agency thinks of the program as creator marketing first, affiliate marketing second.

Its affiliate functionality includes bulk link creation, automated payouts, and tracking performance by creator, campaign, and channel. GRIN - Influencer Marketing Software

GRIN also combines creator discovery, outreach, relationship management, campaign execution, affiliate tracking, and reporting. GRIN - Influencer Marketing Software

I'd favor GRIN if your workflow looks like:

Find creators → recruit them → send products → manage content → give them commission links/codes → measure sales → pay them.

I'd favor impact.com if it looks more like:

Client has creators + affiliates + publishers + referral partners + paid partnerships → establish different commission structures → attribute revenue → reconcile/payout → report ROI.

3. aspire.io — Best for creator relationship management

Aspire is strong if the agency's core service is broader influencer/creator campaign management, with affiliate/ambassador programs as one component.

It supports creator discovery across social channels, relationship workflows, affiliate programs, campaign management, ROI measurement, and Shopify integration. Aspire

I'd put it behind impact.com and GRIN specifically for a commission-program-heavy agency, but ahead of them if your business is primarily influencer campaigns and content production.

4. levanta.com — Interesting if Amazon is important

Levanta is worth considering if a significant percentage of your clients sell through Amazon. It focuses heavily on creator-driven commerce and supports Amazon, Walmart, and Shopify, with creator tracking, payments and tax administration. It recently raised $22M, indicating substantial momentum in the social-commerce space. Business Insider

I wouldn't make it your universal agency platform unless Amazon is a major part of your client mix.

What I'd actually do

For an agency, I'd run demos with impact.com and GRIN first and make them compete against your actual workflow.

Ask each vendor to demonstrate this exact scenario:

10 clients → 100–500 creators per client → Instagram/TikTok/YouTube → unique links + discount codes → different commission rates by client/product/creator tier → Shopify sales attribution → automatic creator payouts → client-specific reporting → agency-level reporting.

Then test these five things particularly hard:

1. Multi-client management — Can your team cleanly separate 10–50 client programs without creating operational chaos?
2. Commission flexibility — Percentage of revenue, flat CPA, tiered commissions, bonuses, product-specific rates, new-vs-returning customers, etc.
3. Attribution — Links, promo codes, last-click/other attribution models, cross-device behavior, refunds/cancellations.
4. Payout operations — Who pays creators, how tax forms are handled, currencies, minimum thresholds, failed payments and reconciliation.
5. Agency reporting — Can you give your client a polished dashboard while your agency has an overarching view of all programs?

My ranking for your specific use case

1. impact.com — best infrastructure for a serious multi-client agency
2. GRIN — best if creators/DTC are the center of the business
3. Aspire — best if broader influencer campaign management is the priority
4. Levanta — best specialized option if Amazon is central

If you tell me roughly how many clients/creators you manage, which channels (TikTok Shop, Instagram, YouTube, Shopify, Amazon, etc.), and whether you need the agency to pay creators on behalf of clients, I can narrow this down to the 2–3 platforms I'd actually buy and compare their pricing/model and agency capabilities.

I'd favor GRIN if your workflow looks like:

Find creators → recruit them → send products → manage content → give them commission links/codes → measure sales → pay them.

I'd favor impact.com if it looks more like:

Client has creators + affiliates + publishers + referral partners + paid partnerships → establish different commission structures → attribute revenue → reconcile/payout → report ROI.

3. aspire.io — Best for creator relationship management

Aspire is strong if the agency's core service is broader influencer/creator campaign management, with affiliate/ambassador programs as one component.

It supports creator discovery across social channels, relationship workflows, affiliate programs, campaign management, ROI measurement, and Shopify integration. Aspire

I'd put it behind impact.com and GRIN specifically for a commission-program-heavy agency, but ahead of them if your business is primarily influencer campaigns and content production.

4. levanta.com — Interesting if Amazon is important

Levanta is worth considering if a significant percentage of your clients sell through Amazon. It focuses heavily on creator-driven commerce and supports Amazon, Walmart, and Shopify, with creator tracking, payments and tax administration. It recently raised $22M, indicating substantial momentum in the social-commerce space. businessinsider.com

I wouldn't make it your universal agency platform unless Amazon is a major part of your client mix.

What I'd actually do

For an agency, I'd run demos with impact.com and GRIN first and make them compete against your actual workflow.

Ask each vendor to demonstrate this exact scenario:

10 clients → 100–500 creators per client → Instagram/TikTok/YouTube → unique links + discount codes → different commission rates by client/product/creator tier → Shopify sales attribution → automatic creator payouts → client-specific reporting → agency-level reporting.

Then test these five things particularly hard:

Yes. If you're an agency managing multiple brands' creator commission programs, I’d evaluate these differently from a normal influencer-marketing platform.

The key requirement is multi-client / multi-brand program management: separate commission rules, creator pools, tracking, payouts, reporting, permissions, and ideally white-labeling—without your team needing a separate login for every client.

My shortlist

1. Levanta — my first choice for e-commerce

If your clients sell through Amazon, Shopify and/or Walmart, I'd put Levanta at the top of the list.

It now lets brands run creator/affiliate programs across Amazon, Shopify and Walmart in one platform, including creator discovery, commission management, product seeding, performance tracking and payouts. Levanta Levanta

Importantly for an agency, Levanta has an agency partner program specifically designed for agencies managing affiliate/creator programs for clients, including partner pricing and dedicated support. Levanta

Choose it if: your definition of "across channels" primarily means Amazon + Shopify + Walmart.

2. Trackdesk — best underlying commission infrastructure

Trackdesk is particularly interesting if what you really need is commission-program infrastructure, rather than a traditional influencer CRM.

Its agency offering supports isolated client workspaces, separate commission rules, affiliates, dashboards, white-label partner portals, custom conversion events, CPA/CPL/CPS/revenue-share/recurring commissions, automated tiers and bulk payouts. Trackdesk

That makes it a strong fit if you have clients with very different program structures—for example:

• Client A: 10% revenue share
• Client B: $25 per qualified lead
• Client C: 20% recurring commission
• Client D: tiered commission based on monthly sales

Choose it if: the commission engine and operational scalability matter more than creator discovery/content management.

3. Referly — best if you want to productize the service

This one is very agency-oriented.

Referly says its agency plans can run up to 60 client affiliate programs from one account, with white-labeling, your own domain, centralized management and the ability to bill clients through your own Stripe setup. Referly Referly

That's compelling if your agency wants to sell:

"We operate your creator affiliate program for $X/month + performance fee"

rather than:

"Here's another SaaS platform you need to buy."

Choose it if: owning the client-facing experience and commercial model is important.

4. GRIN / Aspire — if you need the whole creator lifecycle

I'd look at these if "creator commission program" is really only one component of what you're doing.

For example, if your agency needs:

Discover creators → outreach → negotiate → contracts → send products → collect content → approve content → track sales → calculate commission → pay creators → report to client

then a creator-management platform becomes more attractive than a pure affiliate platform.

Current industry comparisons still position GRIN and Aspire among the major all-in-one creator-management platforms, with Aspire particularly oriented toward campaign-centric workflows. Conbersa

The downside is that you can end up paying for a lot of influencer-management functionality when your actual requirement is performance/commission infrastructure.

5. Plouris — one I'd keep an eye on

Plouris is unusually aligned with the agency-owned creator performance model. It explicitly targets agencies running UGC, paid-social, TikTok Shop, affiliate and creator-commerce programs, with campaign → creative → performance → payout workflows and white-label client experiences. Plouris

I'd put it on the demo list, particularly if TikTok Shop and paid social are important to your agency.

What I'd do in your position

I'd narrow the evaluation to three demos: Levanta, Trackdesk and Referly.

The deciding question is what you mean by "across channels."

If you mean:

Amazon + Shopify + Walmart → Levanta

Lots of different websites/e-commerce platforms + highly customized commission structures → Trackdesk

We want to operate the entire thing as an agency service, with white-labeling and centralized client management → Referly

Creator discovery/content/UGC is equally important as commission tracking → add GRIN/Aspire

One other newer category worth considering is agency-specific multi-tenant infrastructure. For example, HeldSway and Icodrip are explicitly built around multiple client programs, white-labeling and centralized agency management. HeldSway Icodrip

If you tell me roughly (1) how many clients you manage, (2) which channels—Shopify, Amazon, TikTok Shop, Instagram, YouTube, etc.—and (3) whether you need creator discovery/CRM or just commission + tracking + payouts, I can narrow this to the 2–3 platforms I'd actually buy.

If you're an agency managing multiple brands, I’d evaluate this differently from a normal influencer-marketing platform. Your key requirement is really multi-client creator + affiliate/commission infrastructure, not just creator discovery.

My shortlist

The one I'd look at first: impact.com

impact.com is probably the strongest strategic fit if by "creator commission programs" you mean:

Brand → creator → unique tracking link/code → sales/conversions → commission → payout, across multiple channels.

It explicitly brings creators, affiliates, referrals and other partnership types into one platform, rather than treating creator marketing and affiliate marketing as completely separate systems. Impact

That's particularly useful for an agency because you can potentially standardize the underlying program architecture across clients:

• Different commission rates by client
• Different commission rates by creator/tier
• Links/codes and conversion tracking
• Performance-based creator compensation
• Creator/affiliate recruitment
• Campaign and partner management
• Reporting on revenue/conversions
• Multiple partnership types in the same system

The downside is that impact.com is a fairly sophisticated platform. If your clients are mostly small Shopify brands and you're trying to launch programs quickly, it may be more infrastructure than you need.

If you're primarily a creator/ecommerce agency: GRIN

GRIN would be my second demo.

GRIN is much more creator-centric: discovery, relationships, gifting/product seeding, affiliate links, ecommerce attribution, content and payments. Current comparisons specifically position it around ecommerce-native creator programs. Pernav GRIN - Influencer Marketing Software

I'd pick GRIN over impact.com if your workflow looks like:

"We find 100 creators → send them products → manage content → give them affiliate codes → track Shopify revenue → pay commissions."

I'd pick impact.com if it looks more like:

"We operate the client's entire partnership/affiliate channel, with creators being one partner type among several."

The interesting agency-specific options

There are also newer platforms explicitly targeting your operating model.

Trackdesk is particularly interesting if the commission engine is the hard part. Its agency product is designed around isolated client workspaces, separate commissions/affiliates/dashboards, switching between clients, client-specific reports, and a large integration ecosystem. Trackdesk

Influentials is more campaign/influencer oriented and explicitly supports agencies running multiple brand clients, including multi-brand dashboards, team permissions, client reporting and consolidated billing. Influentials Influentials

Shoplinky is another one I'd put on the demo list because it specifically pitches a unified workspace for agencies managing multiple brands, including creator discovery, outreach, affiliate sales and per-client management. Shoplinky

One important distinction

I'd separate the market into two categories:

Creator marketing platforms
→ GRIN, CreatorIQ, Modash, Influentials
Best when your agency's job is finding/managing creators and campaigns.

Partnership/affiliate infrastructure
→ impact.com, Trackdesk
Best when your agency's job is running a measurable revenue channel where creators get paid based on sales/actions.

For your description, I'd lean toward the second category, particularly impact.com, unless the majority of your clients are Shopify/DTC brands where GRIN could be a better operational fit.

If you tell me roughly (1) how many clients, (2) Shopify vs non-Shopify, (3) Instagram/TikTok/YouTube/Amazon/TikTok Shop channels, and (4) whether commissions are % of sales vs flat CPA/other, I can narrow this to the 2–3 platforms I'd actually buy and compare their pricing, agency/multi-tenant setup, attribution, payouts, and channel coverage.

For a marketing agency managing multiple clients, I’d prioritize platforms that support multi-brand workspaces, creator attribution, commission rules, payouts, reporting, and client separation — not just influencer discovery.

The “best” choice depends on whether your creator programs are closer to affiliate/commission-driven commerce (sales commissions, TikTok Shop, Shopify, links) or influencer campaigns (flat fees + deliverables). Here are the strongest fits:

My shortlist for an agency

If you run affiliate / commission programs

1. impact.com

• Best for: “creator earns X% of sales”
• Strong tracking, partner payments, attribution
• Upfluence

• Best for: ecommerce clients wanting creators + affiliate sales
• GRIN

• Best for: Shopify-heavy brands

If you run creator campaigns as an agency service

1. Influentials

• Strong agency fit because it focuses on multiple brands, team access, and client reporting. Influentials
• CreatorIQ

• Best when clients are enterprise and expect sophisticated reporting/governance.
• Collabstr

• Good if you need creator sourcing plus campaign execution in one place. Collabstr

What I would evaluate before buying

For an agency, these features matter more than creator database size:

• Separate client workspaces (so Client A never sees Client B data)
• Agency/team permissions
• White-label reporting
• Creator payout automation
• Commission tracking by creator
• Unique links/codes per creator
• Shopify, TikTok Shop, WooCommerce, Amazon integrations
• API access
• Ability to invoice your client while paying creators yourself

If your agency is primarily doing TikTok Shop, affiliate, and revenue-share creator programs, I’d lean toward impact.com + a creator CRM/workflow tool or a newer agency-performance platform like Plouris. Plouris

If you’re running hundreds of creators across many brand clients with account managers and client reporting, I’d shortlist Influentials, CreatorIQ, or Aspire. Influentials

I can also narrow this down to a top 3 stack based on your agency size, number of clients, channels (TikTok/IG/YouTube/Amazon), and whether commissions are sales-based or flat fees.

If you’re an agency managing creator commission programs for multiple clients, I’d put impact.com at the top of the shortlist.

The key distinction is that you’re not really looking for an “influencer marketing platform.” You need a multi-client performance/affiliate infrastructure that can handle creators, attribution, commissions, payouts, and reporting across channels.

My shortlist

1. impact.com — my pick

impact.com

This is probably the closest match to what you described. impact.com now combines creator, affiliate, referral, and partnership management in one platform, so you can treat creators as performance partners rather than running a separate influencer workflow. impact.com impact.com

For an agency, that's particularly attractive because impact.com explicitly has an agency partner program and says its platform is used by 700+ agency-managed brands. impact.com

I'd choose it if your programs involve things like:

• Revenue-share / CPA commissions
• Creator-specific discount codes and links
• Instagram/TikTok/YouTube creators driving ecommerce sales
• Affiliate partners alongside creators
• Multiple clients and brands
• Automated tracking and payouts
• Client-level performance reporting
• Different commission structures by client/campaign

One important consideration: impact.com's economics include a transaction fee on partner-driven sales, so you should model the total cost against your clients' GMV before committing. GRIN - Influencer Marketing Software

2. CreatorIQ — if you're an enterprise agency

creatoriq.com

I'd look here if you're managing large brands, lots of markets, sophisticated approvals, compliance, and reporting. It's more of an enterprise creator-management system than a pure affiliate platform.

A recent comparison puts CreatorIQ strongest for multi-region/multi-brand programs where finance, legal, and compliance need independent visibility into commission data. Influencers Time

3. GRIN — if most clients are DTC/ecommerce

grin.co

GRIN is worth considering if your agency's creator programs revolve heavily around Shopify/ecommerce, gifting → creator relationship → affiliate commission → revenue attribution.

It's more creator-commerce-centric than impact.com. The tradeoff is that if your clients have broader affiliate/partner ecosystems, impact.com gives you a more unified underlying partnership model.

4. Influentials — interesting if agency workflow is the priority

influentials.com

This one is specifically positioning itself around agencies running campaigns for multiple brands. It provides a multi-brand dashboard, client-specific access, centralized creator payments and client reporting. Influentials

I'd consider it if you want something operationally simpler than the enterprise platforms.

5. Plouris — worth watching for a white-label model

plouris.com

This is particularly interesting if your agency wants to make the creator program feel like your own proprietary platform. It provides separate agency, client and creator portals, with campaigns, performance and payout workflows under your agency's brand. Plouris

That's a different proposition from impact.com: you're essentially buying infrastructure for your agency's creator-performance service, rather than sending clients into a third-party creator platform.

What I'd do in your shoes

If you're managing 10+ client brands, I'd shortlist:

impact.com → CreatorIQ → GRIN

and add Plouris if white-labeling/agency ownership is strategically important.

The biggest question I'd use to decide between them is where the commission calculation happens. If you need something like:

Creator posts on TikTok → customer clicks creator link → purchases on Shopify → later purchases again → commission is calculated according to Client A's rules → refund deducted → creator gets paid → agency/client gets reporting

then I'd strongly favor a performance/affiliate-native platform like impact.com rather than a traditional influencer campaign platform.

If you tell me roughly how many clients, creators, monthly GMV, and which channels (Shopify, Amazon, TikTok Shop, YouTube, Instagram, etc.), I can narrow this to the 2–3 platforms that actually fit your agency and compare their pricing, attribution, payout, API, white-label, and multi-client capabilities.

For a marketing agency managing multiple clients and running creator commission programs across channels (TikTok, Instagram, YouTube, affiliate links, Shopify/DTC, SaaS referrals, etc.), I’d prioritize platforms that have:

• Multi-client / multi-brand workspaces
• Separate commission rules per client
• Creator onboarding + tracking links/codes
• Automated payouts and tax/payment workflows
• Client-facing dashboards
• White labeling (if you sell this as a service)
• Cross-client reporting for your agency team

The “best” choice depends on whether you are closer to an influencer agency or an affiliate/performance marketing agency.

Best overall fits for an agency

1. Trackdesk — best for performance + affiliate-style creator commissions

Best fit if creators are driving measurable revenue (sales, leads, subscriptions).

Strengths:

• Multiple client programs from one platform
• Separate tracking, commissions, affiliates, and dashboards per client
• Supports CPA, CPL, CPS, recurring commissions, rev share, and tiered commissions
• Strong reporting workflows for client reporting Trackdesk

Good for:

• DTC brands
• SaaS clients
• Subscription products
• Agencies managing affiliate programs as a retainer service

Potential downside:

• Less focused on creator relationship management (briefs, content approvals, gifting workflows).

2. CreatorIQ — best enterprise creator marketing platform

Best if your clients are larger brands and you need full influencer operations.

Strengths:

• Creator discovery
• Relationship management
• Campaign management
• Reporting
• Enterprise workflows

Good for:

• Beauty, fashion, consumer brands
• Large creator networks
• Global campaigns

Potential downside:

• Usually heavier and more expensive than what a boutique agency needs.

3. GRIN — best for ecommerce creator programs

Good if most clients are Shopify/ecommerce brands.

Strengths:

• Creator CRM
• Product seeding
• Affiliate links/codes
• Influencer relationship workflows

Good for:

• Shopify brands
• Ambassador programs
• Repeat creator partnerships

Potential downside:

• More brand-operated than agency-operated.

4. Impact.com — best for sophisticated partner ecosystems

Good if creators are one piece of a broader partner channel.

Strengths:

• Influencers + affiliates + partnerships
• Enterprise tracking
• Payments
• Contracting workflows

Good for:

• Agencies with larger clients
• Complex attribution needs

Potential downside:

• More infrastructure than many creator programs require.

5. Agency-first affiliate platforms (worth evaluating)

If your agency wants to operate 20+ client programs under one roof, look at newer agency-focused tools:

• Rekomi focuses on multi-client affiliate program management, with separate client organizations, white-label options, and agency workflows. Rekomi
• HeldSway positions itself specifically around agencies running multiple client programs, including white-label client portals and portfolio reporting. HeldSway
• Referly is aimed at agencies wanting white-labeled affiliate software under their own brand. Referly

My shortlist by agency model

What I’d pick for a typical marketing agency

• 5–20 clients, performance-based creator commissions: Trackdesk or Rekomi
• UGC/influencer campaigns plus commissions: GRIN or CreatorIQ
• You want to package “creator commerce management” as a service: HeldSway/Referly-style agency platforms

A few questions would narrow this down a lot:

1. Are your clients mostly Shopify/ecommerce, SaaS, or mixed?
2. Do creators get paid mainly by affiliate sales commissions, flat campaign fees, or both?
3. Roughly how many client programs do you expect to run (5, 20, 100+)?

Yes. For a marketing agency managing creator commission programs across multiple clients, I’d narrow the field considerably. The best fit is probably impact.com, with GRIN and Aspire as the two alternatives worth evaluating.

My ranking

1. impact.com — my first choice for an agency

If your core requirement is "we need to run performance/commission programs for lots of different clients", I'd start here.

impact.com is designed around managing creators, affiliates, referrals, and other partners in one platform, rather than treating creator marketing as a standalone influencer workflow. impact.com impact.com

That's particularly valuable for an agency because you can have, for example:

• Client A → TikTok creators → 15% commission
• Client A → Instagram creators → 10% commission
• Client A → affiliates → 8% commission
• Client B → YouTube creators → $25 CPA
• Client B → publishers → revenue share
• Client C → creator + affiliate hybrid program

…and manage those relationships within the same partnership infrastructure.

It also has a dedicated agency partner program, including agency-specific tools, support, certification and revenue-sharing opportunities. impact.com says its platform is already used by 700+ active agency-managed brands. impact.com

impact.com

The downside: it's more of a partnership/affiliate platform than a pure creator-ops platform. If your clients care heavily about gifting, content approvals, briefs, creator relationships, etc., GRIN or Aspire may feel more natural.

2. GRIN — best if "creator" is the center of the program

GRIN is particularly compelling if you're mostly working with DTC/e-commerce clients and creators, rather than traditional affiliate partners.

It supports affiliate links, creator-level tracking, commission tiers, milestone rewards, automated payouts and campaign/product workflows. GRIN - Influencer Marketing Software

It also tracks performance by creator, campaign and channel, which is important if you're reporting back to multiple clients. GRIN - Influencer Marketing Software

I'd choose GRIN over impact.com if your agency's workflow looks more like:

Find creators → recruit → negotiate → send product → get content → track sales → pay commission → report ROI

rather than:

Recruit partners → establish commission structures → track transactions → optimize affiliate/creator revenue

grin.co

3. Aspire — excellent for creator/ambassador programs

Aspire is another strong option if the program is creator-first.

It specifically supports personalized commission structures, affiliate links, promo codes, flat/percentage/tiered commissions, campaign management, creator content, payments and reporting. Aspire

So if your clients are asking for "build us an ambassador program" rather than simply "build us an affiliate channel," Aspire deserves a serious look.

aspire.io

What I'd do in your shoes

I'd demo impact.com and GRIN side-by-side.

The deciding question is:

Are you primarily an agency operating performance partnerships, or an agency operating creator programs that happen to pay commissions?

If it's the former → impact.com.

If it's the latter → GRIN.

If you're somewhere in between → Aspire is worth adding to the evaluation.

One particularly important consideration for an agency is multi-client architecture. Don't just ask vendors whether they support "multiple brands." Ask them to demonstrate how your team would actually manage 20 clients, each with 50–500 creators, different commission rules, different ecommerce stores, separate reporting, separate payouts, and different users/permissions. That's where the platforms can differ dramatically.

Also, current pricing makes the economics worth scrutinizing: impact.com publicly lists tiers starting at $30/month, $500/month and $2,500/month, with enterprise pricing available, plus a published 2.5% charge on partner-driven sales. GRIN - Influencer Marketing Software

If you tell me roughly how many clients you manage, creator volume per client, whether they're mostly Shopify/DTC, and which channels (TikTok, Instagram, YouTube, Amazon, etc.), I can give you a much more definitive "buy X" recommendation and a feature/pricing comparison for your agency model.

For a marketing agency managing creator commission programs across multiple clients, I’d put impact.com at the top of the shortlist.

The key distinction is that you don’t just need an influencer-management tool—you need a multi-client performance/affiliate infrastructure that can handle creator recruitment, commission rules, attribution, contracts, payouts, reporting, and ideally multiple commerce channels.

My shortlist

1. impact.com — best overall for your use case

This is the one I'd investigate first.

impact.com now combines creator, affiliate, and referral programs in one platform, rather than treating influencer marketing and affiliate marketing as separate systems. It supports the entire workflow from discovery/recruitment through contracting, tracking, commission structures, and payments. impact.com impact.com

For an agency, that's particularly attractive because you can build programs around different clients while keeping the underlying operating model consistent.

It also supports dynamic payouts, different partner types, cross-device attribution, automated payments, and partner-level reporting. Impact

I'd choose it if: you're managing serious programs for multiple brands and want an infrastructure platform rather than simply a creator CRM.

impact.com

2. GRIN — best if you're primarily a creator agency

grin.co is particularly compelling if your programs are creator-led rather than traditional affiliate-led.

Its affiliate product lets you create links in bulk, track performance by creator/campaign/channel, set commission tiers and milestone rewards, and automate payouts. GRIN - Influencer Marketing Software

It also has a large transaction-verified creator database, which is useful if your agency is responsible for finding and activating creators, not just operating the commission infrastructure. GRIN

I'd choose it if: creator discovery, relationships, gifting/content workflows, and affiliate commissions all need to live together.

3. Captiv8 — worth looking at for enterprise creator operations

captiv8.io takes a broader influencer-marketing approach, combining discovery, workflow, measurement and creator commerce. Its commerce capabilities include affiliate, TikTok Shop, branded storefronts and attribution. Captiv8

I'd choose it if: your agency does substantial influencer campaign management in addition to commission programs.

4. Levanta — particularly interesting if Amazon is important

levanta.io is unusually interesting if your clients sell across Amazon, Shopify and Walmart. Its current platform explicitly lets brands run creator/affiliate programs across those three channels, with commissions, product seeding, flat-fee partnerships, attribution and payments. Levanta Levanta

I'd choose it if: marketplace commerce—especially Amazon—is a major part of your clients' business.

5. Refersion — good simpler/cheaper affiliate infrastructure

refersion.com is more traditional affiliate software. It offers flexible commission structures, SKU/product-level tracking, multi-store management, integrations and automated payouts. Refersion

I'd consider it when the requirement is essentially "give our creators affiliate links/codes, track sales and pay commissions", rather than full creator-program management.

What I'd do in your position

I'd narrow the evaluation to impact.com vs. GRIN vs. Levanta.

The deciding question is really your clients' commerce mix:

• Mostly DTC / Shopify + sophisticated creator programs → GRIN
• Creator + affiliate + referral + multiple channels → impact.com
• Amazon + Shopify + Walmart → Levanta
• Large enterprise influencer campaigns + commerce → Captiv8
• Basic affiliate infrastructure → Refersion

For an agency specifically, I'd lean impact.com because the conceptual model is closest to what you're describing: one performance-partnership layer that your agency can operate across many brands, rather than a tool that's primarily designed around one brand's influencer team. impact.com also explicitly has an agency partner program. impact.com

If you tell me (1) how many clients/brands you manage, (2) Shopify/Amazon/TikTok Shop/etc., (3) whether creators get % commission, flat fees, or both, and (4) roughly how many creators per client, I can narrow this down to the 2–3 platforms I'd actually demo, including the important agency-specific differences (multi-brand management, white-labeling, reporting, pricing, payouts, attribution, and API/integrations).

This is the one I'd investigate first.

I'd choose it if: marketplace commerce—especially Amazon—is a major part of your clients' business.

I'd consider it when the requirement is essentially "give our creators affiliate links/codes, track sales and pay commissions", rather than full creator-program management.

What I'd do in your position

I'd narrow the evaluation to impact.com vs. GRIN vs. Levanta.

The deciding question is really your clients' commerce mix:

Yes. For a marketing agency managing creator commission programs for multiple clients, I’d narrow the field to impact.com, GRIN, and Levanta—but the best choice depends heavily on which commerce channels you need to support.

My ranking

🥇 My pick: impact.com

For an agency, impact.com is probably the strongest platform to evaluate first.

It has evolved beyond traditional affiliate tracking into a unified platform for creators, affiliates, ambassadors and customer referrals, with customizable commission structures, partner recruitment, tracking, reporting and payouts. impact.com

The important part for you is that it is designed around performance partnerships rather than just influencer campaigns. You can have different commission rules, partner types and reporting structures rather than forcing every client into the same creator workflow. impact.com also explicitly has an agency partner ecosystem. get.impact.com

I'd choose it if your agency is managing:

• Multiple brands/clients
• Creators + traditional affiliates
• Different commission structures by client/campaign
• Web/e-commerce conversions
• TikTok/Instagram/YouTube creators
• Larger programs where attribution and reporting matter
• Clients who will eventually want more sophisticated partnership marketing

Explore impact.com

🥈 GRIN — better if you're primarily a creator/influencer agency

GRIN is arguably the nicer creator-management experience. It handles creator discovery, relationships, campaigns, content, affiliate links, tracking and payouts in one system. grin.co

Importantly for an agency, GRIN explicitly supports multiple brands and campaigns within one platform, and its affiliate functionality can create links in bulk and track performance by creator, campaign and channel. grin.co

I'd lean GRIN over impact.com if your actual business looks like:

"We manage 20 DTC brands and our core job is recruiting/managing creators, sending products, collecting content, and turning those creators into commission-based affiliates."

I'd lean impact.com if it looks more like:

"We run the clients' entire performance partnership infrastructure and creators are one channel within it."

Explore GRIN

🥉 Levanta — very interesting if Amazon is important

Levanta deserves serious consideration if your clients sell through Amazon, Shopify and Walmart. Its 2026 platform expansion specifically brought those three commerce channels together for creator/affiliate programs. levanta.io

It also has an explicit agency partner program, including tools/support for agencies managing affiliate and creator programs for clients. levanta.io

So if your agency's world is heavily:

Amazon + TikTok creators + Shopify + Walmart

I'd put Levanta much higher on the shortlist.

Explore Levanta

The big distinction I'd make

Don't evaluate these platforms primarily on "influencer management."

For an agency, I'd evaluate them on multi-tenant performance infrastructure:

1. Can we isolate each client completely?
2. Can our agency team manage all clients from one login?
3. Can each client have different commission rules?
4. Can a creator belong to multiple client programs without creating duplicate accounts?
5. Can we track Shopify + Amazon + other channels?
6. Can we automate creator onboarding?
7. Can we automate commission calculations and payouts?
8. Can clients have their own dashboards/reporting?
9. Can we export/API all conversion and commission data?
10. Can we attribute sales across multiple creator channels?
11. Can we handle promo codes as well as affiliate links?
12. Can we charge clients a management fee while the platform handles creator payouts?

That last group is where impact.com becomes particularly compelling for an agency.

What I'd do in your position

I'd run a bake-off between impact.com and GRIN, and add Levanta if Amazon/Walmart is meaningful to your client base.

If you tell me (1) how many clients you manage, (2) Shopify/Amazon/TikTok Shop/etc., (3) approximate number of creators, and (4) whether you need the platform to actually pay creators, I can give you a much more definitive recommendation—including pricing, multi-client architecture, integrations, attribution, payouts, and the major gotchas for an agency.

Yes. For a marketing agency managing creator commission/affiliate programs for multiple clients, I’d narrow the field considerably.

My shortlist

🥇 I'd start with impact.com

The key distinction is that you aren't just looking for an influencer-management tool. You're looking for performance-partnership infrastructure that your agency can operate across multiple brands and channels.

impact.com now combines creators, affiliates and referrals in the same platform, with tracking, partner management and payouts unified. It explicitly has an agency offering as well. impact.comhelp.impact.com

That makes it particularly interesting if your clients might have programs involving:

• TikTok / Instagram creators
• YouTube creators
• Traditional affiliates
• Coupon/deal partners
• Ambassadors
• Customer referral programs
• Multiple commission structures
• Link + promo-code attribution
• Different programs for different clients

Its creator product is now integrated directly into the Performance Platform, so you don't have to treat influencer marketing and affiliate marketing as separate systems. impact.com

See impact.com's agency/platform offering

🥈 GRIN if your agency is primarily creator-led

GRIN is arguably the better creator operating system. It handles creator discovery, recruitment, campaign management, affiliate links, commissions, tracking and payouts. GRIN says its affiliate functionality tracks performance by creator, campaign and channel and supports commission tiers and automated payouts. grin.co

It's especially compelling if your clients are DTC brands and the program looks like:

recruit creators → send product → creator posts → creator gets unique link/code → sale → commission → payout

Rather than:

manage a broad ecosystem of affiliates, publishers, creators, referrals and partnerships.

GRIN has also been pushing heavily into automated/AI-operated creator-program management, which could be useful for an agency trying to reduce account-management labor. grin.co

🥉 Modash if ease of use matters

Modash is worth looking at if your clients are predominantly Shopify/DTC. Its creator-affiliate tooling focuses specifically on the combination of creator recruitment, commission structures, attribution, discount codes, creator portals and payouts—rather than treating affiliate tracking as just another link-management problem. www.modash.io

The important agency-specific question

I'd actually evaluate these platforms on agency infrastructure, not just features.

You want to know whether you can have:

Agency
→ Client A
→ Client B
→ Client C
→ Client D

with each client having isolated:

• creators
• commission rules
• links/codes
• campaigns
• attribution
• payouts
• reporting
• client access

while your agency retains one operational layer across all of them.

That's where I'd put impact.com ahead of GRIN/Modash if you're building this as a serious agency service. impact.com is designed around broader partnership management and explicitly supports agencies. impact.comhelp.impact.com

My recommendation by agency type

If you have 10+ clients and want to build a scalable managed service:
→ impact.com

If you're a creator/influencer agency and commissions are an extension of creator campaigns:
→ GRIN

If most clients are Shopify brands and you want something easier/lower-friction:
→ Modash

If you mostly need "give creators links/codes and pay them commission":
→ consider a lighter affiliate-first product rather than a full creator-management suite.

If you tell me roughly how many clients you manage, Shopify vs non-Shopify, which channels (TikTok/IG/YouTube/etc.), and whether you need the agency to invoice/collect money from clients, I can give you a much more specific recommendation—including which platform I'd actually buy and why, plus a feature/pricing comparison.

For a marketing agency managing creator commission programs across multiple clients and channels, I’d shortlist these:

My pick: impact.com

If your model is "we run performance-based creator programs as a service for multiple brands," I'd start with impact.com.

The big advantage is that it isn't just an influencer CRM. Its Creator product is integrated with its affiliate/performance platform, so you can have creators, affiliates, referral partners, links/codes, attribution, commissions and payouts in the same system. It specifically supports agencies and says it has 700+ active agency-managed brands. impact.com

That matters if, for example, a creator is:

• posting on TikTok → commission on tracked sales
• posting Instagram Stories → unique link/code
• publishing YouTube content → revenue share
• participating in a traditional affiliate program → same partner record
• getting a hybrid flat fee + % commission → same workflow

You can manage the creator relationship and performance side together rather than bolting an influencer platform onto an affiliate tracker.

When I'd choose something else

GRIN — choose this if the heart of the operation is creator marketing, with affiliate commissions as an important component. GRIN has a large creator network, creator discovery, outreach, campaign management, affiliate links, bulk link creation and payouts. grin.co

Trackdesk — interesting if your agency is more performance/affiliate marketing than influencer marketing. Its agency product is explicitly designed around isolated client workspaces, client-specific commissions, dashboards, reporting and white-label partner portals. impact.comgrin.cotrackdesk.com

HeldSway — particularly interesting if you want to turn this into a white-labeled service that your agency sells to clients. It supports separate programs per client, client-specific branding, role-based permissions, centralized agency billing and a portfolio-wide dashboard. heldsway.com

Commission Factory — worth looking at if you're operating substantial traditional affiliate programs across multiple markets. Its agency offering is explicitly multi-client/multi-market, with tracking, reporting, recruitment and automated payouts. www.commissionfactory.com

The key distinction

I'd think about the decision this way:

Creator-first agency → GRIN
Creator + affiliate + referral performance → impact.com
Affiliate/performance agency → Trackdesk or Commission Factory
White-label "affiliate program as a service" → HeldSway

If you tell me roughly how many clients you manage, how many creators per client, Shopify vs other ecommerce platforms, and whether you need TikTok/Instagram/YouTube attribution, I can narrow this to the 2–3 platforms I'd actually demo and compare their pricing/limitations.

Yes. For a marketing agency managing creator commission programs for multiple clients, I’d evaluate this differently from a normal influencer-marketing platform. The key is multi-client workspaces + commission attribution + creator payouts + cross-channel reporting, rather than just creator discovery.

My shortlist

🥇 My first look: Growi

Growi

Growi is particularly interesting for your use case because it is designed around creator commerce rather than just influencer campaigns. It supports TikTok Shop, Shopify, Amazon, Meta and TikTok, with creator-level attribution, commissions, retainers, bonuses and payouts. www.growi.io

That means you could theoretically have:

Client A
→ 40 creators
→ 15% commission
→ TikTok Shop + Shopify
→ monthly bonuses

Client B
→ 100 creators
→ different commission tiers
→ Amazon + Shopify
→ performance bonuses

…and manage the programs from the same operating layer.

The cross-channel piece is particularly compelling: Growi says it can tie creator content and sales across TikTok, Instagram, Facebook, YouTube, Shopify, Amazon and paid channels back to individual creators. www.growi.io

🥈 GRIN — safest established choice

GRIN

If you're looking for something more established and don't mind a potentially heavier/enterprise-oriented platform, GRIN would be my second choice.

It combines creator management, affiliate programs, tracking, commission tiers, automated payouts, product fulfillment and creator relationship management. grin.co

Its affiliate system can track performance by creator, campaign and channel, which is exactly the reporting structure an agency needs. grin.coeightx.co

The downside is economics: third-party estimates put typical GRIN contracts in the ~$30k–$50k/year range for mid-market DTC brands, although actual pricing varies considerably by contract. eightx.co

🥇 Wildcard: Plouris

Plouris

This one is very specifically interesting for an agency.

Plouris describes itself as an agency-owned creator performance platform: your agency retains the client/creator relationships while the software provides the infrastructure underneath. It supports UGC, TikTok Shop, affiliate, ambassador and creator-commerce programs, including campaign management, performance and payout workflows. www.plouris.com

If your business model is:

"We sell creator affiliate programs to brands as a managed service."

rather than:

"We're a brand using software to manage our own creators."

I'd put Plouris on the demo list.

Social Cat — worth considering for easier deployment

Social Cat for Agencies

Social Cat explicitly supports multiple client brands under one agency account, with gifted, paid and affiliate campaigns, creator discovery and reporting. thesocialcat.com

I'd consider it if you want something relatively straightforward and don't need the sophisticated attribution/commerce infrastructure of Growi or GRIN.

Where Impact.com fits

impact.com

I'd choose Impact when the programs are becoming more like full affiliate/partnership programs—creators + affiliates + publishers + other partners—with sophisticated attribution and partner economics.

For a pure creator-commerce agency, though, I think Growi/GRIN/Plouris are more naturally aligned.

One important distinction

If by "across channels" you mean:

Instagram + TikTok + YouTube + Shopify + Amazon + TikTok Shop,
then I'd prioritize Growi or Plouris.

If you mean:

creators + traditional affiliates + publishers + referral partners + coupon sites,
then I'd lean Impact.com.

If you mean:

large-scale influencer/creator management with sophisticated CRM, content, seeding and affiliate functionality,
then GRIN is probably the safer bet.

If you want, I can also do a serious agency-focused comparison of Growi vs GRIN vs Impact vs Plouris, including multi-client architecture, white-labeling, commission rules, attribution, Shopify/TikTok Shop/Amazon integrations, creator payments, reporting, API capabilities, and estimated pricing.

For a marketing agency managing multiple clients, I’d prioritize platforms that support multi-brand workspaces, creator onboarding, commission tracking, attribution, payouts, reporting, and client visibility. The “best” choice depends on whether you’re mainly running affiliate/commission programs, influencer campaigns, or UGC + performance creative.

Here’s how I’d shortlist them:

My recommendation by agency model

1. You manage Shopify/ecommerce clients and creators earn commissions on sales

• Start with impact.com or LoudCrowd.
• They’re closer to a true affiliate infrastructure: tracking links/codes, conversions, commission rules, payouts. loudcrowd.comimpact.com

2. You’re an influencer marketing agency with 10–100+ brand clients

• Look hardest at Influentials or Plouris.
• The important features are not creator discovery; they’re:
  • separate client workspaces
  • client approvals
  • white-label reporting
  • creator contracts
  • consolidated payouts
  • agency-owned creator relationships www.plouris.comwww.influentials.comloudcrowd.com

3. You run TikTok Shop / UGC / paid social creative programs

• I’d lean Plouris or LoudCrowd because the workflow is closer to:

creator → content → performance → commission. www.plouris.comwww.influentials.comloudcrowd.com

Features I’d insist on before buying

For an agency, I’d avoid tools that only manage campaigns for one brand. Make sure it has:

• ✅ Multi-client dashboard
• ✅ Client-level permissions
• ✅ Creator CRM/roster reuse across clients
• ✅ Commission rules (flat fee + % revenue + bonuses)
• ✅ Discount codes + affiliate links
• ✅ Automated creator payouts
• ✅ Exportable client reports
• ✅ API/webhooks if you connect Shopify, WooCommerce, TikTok Shop, etc.

If I were choosing a stack for a mid-size creator marketing agency, my shortlist would be:

1. impact.com — if revenue attribution is the core product
2. Plouris — if your agency wants a branded creator-performance operating system
3. Influentials — if you need a straightforward multi-client influencer operations hub
4. LoudCrowd — if most clients are DTC/ecommerce

A few details would change the answer significantly: how many clients you manage, whether commissions are based on sales (affiliate) or content delivery (creator fees), and which channels matter most (TikTok Shop, Instagram, YouTube, Amazon, Shopify, etc.).

If you’re an agency managing creator commission programs for multiple clients, I’d shortlist these three—but they solve slightly different problems:

My recommendation

1. impact.com — best overall if “commission” is the core of the business.

It has a particularly strong fit if your creators can earn based on sales, conversions, referrals, or other performance events, because it brings creator, affiliate, and referral programs into the same partnership platform. impact.com

I'd choose this if you expect programs to span things like:

• Instagram/TikTok/YouTube creators
• Affiliate links and promo codes
• Ecommerce sales
• Different commission rates by creator/tier
• Multiple clients/brands
• More sophisticated attribution and reporting

2. Trackdesk — best if you're essentially an affiliate agency with creators as the affiliates.

Its agency product specifically supports isolated client workspaces, separate commission/affiliate data, client dashboards and branded reporting, and it advertises 900+ integrations. trackdesk.com

This is probably the most interesting option if your workflow is:

Client → offer → creator/affiliate → tracking link/code → conversion → commission → payout → client report

rather than a traditional influencer-campaign workflow.

3. Plouris — most interesting if you want to build a creator-performance offering under your agency's brand.

This one is newer, but its positioning is unusually close to what you described: agency-owned infrastructure for UGC, paid social, TikTok Shop, affiliate and creator-commerce programs, with client workspaces, creator portals, performance data and payout rules. www.plouris.com

The big advantage is that your agency owns the client and creator relationship and can present the system as your own branded platform.

What I would not make my first choice

I wouldn't start with a conventional influencer-management platform like GRIN or Creator.co if the primary requirement is commission attribution across channels. They're stronger when the center of gravity is creator discovery, campaigns, content, relationships and influencer management. GRIN, for example, is particularly comprehensive as a creator CRM/management system. www.conbersa.ai

Creator.co does have a dedicated multi-brand agency offering, so it's worth considering if your programs are more campaign/influencer-oriented than affiliate-oriented. www.creator.co

If I were choosing for an agency

I'd rank them:

impact.com → Trackdesk → Plouris

But the winner changes depending on your exact model.

If you tell me (1) how many clients, (2) roughly how many creators per client, (3) which channels—TikTok, Instagram, YouTube, Shopify, Amazon, etc.—and (4) whether commissions are based on sales, clicks, leads, or GMV, I can narrow this down to the best 2–3 platforms and tell you exactly why, including pricing/implementation considerations.

For a marketing agency managing multiple client brands, I’d shortlist GRIN, impact.com, and Modash—but my pick depends on whether you’re primarily selling creator marketing or affiliate/performance marketing to clients.

My ranking

🥇 I'd start with GRIN

GRIN is probably the closest match to what you're describing. It combines creator recruitment, relationship management, campaigns, affiliate links/codes, commission tiers, performance reporting, and creator payments rather than making you bolt an affiliate platform onto an influencer platform. grin.co

It also explicitly tracks performance by creator, campaign, and channel, and supports automated payouts and commission incentives. grin.co

For an agency, that's valuable because you can essentially make the workflow:

Client → creator roster → offers/commission structure → content → sales attribution → commissions → reporting

rather than maintaining separate systems for influencer management and affiliate tracking.

GRIN's current pricing also has tiers designed around running multiple programs, with its higher plans supporting up to 250 or 500 active creators in the classic workspace. grin.co

🥈 impact.com if "across channels" is the priority

I'd look harder at impact.com if by across channels you mean you're managing creators + traditional affiliates + referral partners + other partnership types for each client.

impact.com positions itself as a unified platform for creators, affiliates, customer referrals, and communities, rather than purely a creator-management system. impact.com

So:

• GRIN → creator-first agency
• impact.com → partnership/affiliate-first agency

🥉 Modash is particularly interesting for ecommerce clients

Modash is worth a serious demo if most of your clients are Shopify/DTC brands. It combines creator discovery, CRM, campaign management, affiliate tracking and payouts. www.modash.io

Its affiliate system supports unique links + discount codes, commission tiers, attribution, creator dashboards and payouts. help.modash.io

One notable limitation: its affiliate program currently requires a connected Shopify store and Modash Payments, so I'd be less inclined to make it your agency-wide standard if your clients use lots of different ecommerce stacks. help.modash.io

One important distinction

If what you really want is "we operate creator affiliate programs as a service for 20–100 brands", I'd evaluate these platforms differently than a single brand would.

I'd specifically test:

1. True multi-client / multi-brand management
2. Separate client dashboards and reporting
3. White-label/client-facing reporting
4. Multiple Shopify/store connections
5. Commission rules by product, creator, campaign, etc.
6. TikTok + Instagram + YouTube attribution
7. Discount-code attribution alongside links
8. Automated creator payouts and tax forms
9. Bulk creator onboarding
10. API/webhooks for pushing data into your agency's BI/reporting stack
11. Whether your team can manage all clients from one agency account
12. Whether clients can have restricted access to only their own data

That last group is where the decision can change dramatically. A platform that's excellent for one DTC brand isn't necessarily good agency infrastructure.

If you tell me roughly how many clients you manage, average creators/client, ecommerce platforms (Shopify/WooCommerce/etc.), and whether you need white-label client reporting, I can narrow this to the best 2–3 options and compare their agency/multi-client capabilities and pricing.

For a marketing agency managing multiple clients, I’d put impact.com at the top of the list—especially if by “creator commission programs” you mean performance-based creator/affiliate programs where creators earn commissions on sales across multiple channels.

My shortlist

1. impact.com — my pick for your agency

Impact has moved toward a unified platform covering creators + affiliates + customer referrals, rather than treating creator marketing as a separate influencer tool. It supports tracking, contracts, commission structures, payouts, campaign management, discovery, and reporting. impact.comhelp.impact.com

The important part for an agency: Impact specifically has an agency solution designed around managing a portfolio of client programs, with portfolio-level visibility and the ability to manage multiple customer relationships/programs from one platform. help.impact.com

I'd choose it if you're doing things like:

• Client A: TikTok creators → Shopify sales → 15% commission
• Client B: Instagram creators → DTC site → CPA commission
• Client C: YouTube creators → Amazon → commission
• Client D: affiliates + creators + referral partners
• Different commission rates, offers, contracts and reporting per client
• Agency wants centralized operations but client-specific reporting

It also handles tracking across properties/devices and supports flexible/dynamic payout structures. impact.com

2. GRIN — better if creator relationships are the center

GRIN is particularly compelling if your programs are more creator/influencer-led than traditional affiliate-led. Its affiliate product handles bulk link creation, tracking, commissions and payouts, with performance reporting by creator, campaign and channel. launch.grin.co

I'd lean GRIN if your agency is doing a lot of:

creator recruitment → product seeding → content → affiliate links → commissions → ongoing creator relationships.

It's less of a pure partnership/affiliate infrastructure play than Impact and more creator-centric.

3. Levanta — interesting if Amazon is important

Levanta is worth looking at if your clients sell heavily through Amazon, Walmart and Shopify. In 2026 it expanded its creator affiliate infrastructure to unify product discovery, link generation, commission tracking and payments across those three channels. levanta.io

For an agency with lots of Amazon creator programs, I'd put it much higher on the list.

What I'd actually do in your situation

Start with Impact and GRIN.

If you're a true multi-client agency, I'd probably choose:

Impact = infrastructure / attribution / commissions / multi-client operations
GRIN = creator CRM / recruitment / relationship management / content

If you want one system rather than stitching tools together, Impact has the stronger argument because creators and conventional affiliates can live in the same partnership infrastructure. impact.com

One important caveat: “across channels” can mean two very different things—tracking creators across social channels (TikTok, Instagram, YouTube, etc.) versus tracking sales channels (Shopify, Amazon, Walmart, retail, apps, etc.). Impact is particularly strong when you mean the latter + the former.

If you tell me (1) how many clients you manage, (2) roughly how many creators per client, and (3) which sales channels—Shopify/Amazon/Walmart/etc.—I can narrow this down to the best 2–3 and compare **pricing, agency/multi-brand architecture, creator onboarding, commission rules, attribution, payouts, and white-label/client reporting.

Yes. For a marketing agency managing multiple clients, I’d narrow the field considerably. You don’t just need creator software—you need multi-client program management + affiliate/commission infrastructure + cross-channel attribution + payouts/reporting.

My shortlist

🥇 I'd start with impact.com

impact.com

The reason is that your requirement sounds more like "run performance partnerships for lots of brands" than simply "manage influencer campaigns."

impact.com now brings creator, affiliate, and referral programs into one platform, with unified tracking. It specifically supports agencies and says agencies can build campaigns across brands. impact.com

That matters if, for example, one client's program looks like:

TikTok creator → unique link → Shopify sale → 15% commission

while another is:

YouTube creator → promo code → sale → $20 commission

and another is:

Instagram creator → affiliate link → tiered commission → bonus at $10k revenue

You want all of that living in the same underlying partnership system rather than stitching together an influencer platform + affiliate software + spreadsheets.

impact.com also supports creator discovery, campaign management, performance tracking and payments, and says its creator capabilities are now integrated into the broader performance platform. impact.comimpact.com

🥈 Upfluence is probably the one I'd demo alongside it

Upfluence

This is particularly interesting for an agency. Upfluence explicitly supports agencies running separate programs, workspaces and reporting for each brand from one account. It also supports custom commission tiers, affiliate links/codes, flat-fee + commission hybrid deals, and creator payouts. www.upfluence.com

Its positioning is more creator-marketing-centric than impact.com. So if your agency is primarily:

Find creators → negotiate → send product → get content → turn creators into affiliates → track revenue

I'd seriously consider Upfluence.

🥉 GRIN

GRIN

GRIN is very strong if the creator relationship is the center of the operation. It handles creator management, communications, content, campaign workflows, ROI tracking and payments. Its affiliate product can bulk-create links and track performance by creator, campaign and channel. grin.co

GRIN also explicitly supports agencies managing multiple brands/campaigns. grin.co

I'd put it behind impact/Upfluence for your particular wording because you emphasized commission programs across channels, which pushes me toward a performance-partnership platform.

Aspire

Aspire

Aspire is another very credible option. It supports affiliate links, promo codes, flat/percentage/tiered commissions, creator incentives and revenue reporting. www.aspire.io

I'd look at Aspire particularly if you want the programs to be ambassador/community + influencer + affiliate, rather than purely performance affiliate.

The important distinction

I'd actually choose based on this:

If 60–80% of your work is commission/performance → impact.com

If 60–80% is creator/influencer management that also happens to have commissions → Upfluence

If you're a large creator-management operation → GRIN

If you're building ambassador/influencer communities → Aspire

For an agency, impact.com is my first demo because it gives you the broadest performance infrastructure. Its platform currently covers affiliates, creators, referrals and other partnership types, and the company says it powers more than 2 million partnerships. impact.com

One caveat: pricing and agency account architecture are important here. I wouldn't select based on feature checklists alone. I'd make each vendor demo the exact workflow you need: create client → launch program → recruit creators → assign commission rules → track Shopify/Amazon/other channel sales → approve commissions → pay creators → produce client-level reporting.

If you tell me (1) how many clients you manage, (2) Shopify/DTC vs other channels, (3) roughly how many creators per client, and (4) whether you need creator discovery/outreach too, I can give you a much more definitive “buy X, not Y” recommendation and a side-by-side of the 3 best fits.

For a marketing agency managing multiple client brands, I’d narrow the field to impact.com, Aspire, and GRIN—but my default recommendation is impact.com if your core need is creator commissions across multiple channels, rather than just influencer campaign management.

My shortlist

🥇 I'd start with impact.com

The big advantage for an agency is that impact.com treats creators as one type of performance partner alongside traditional affiliates, ambassadors, and referrals. That means you aren't building a separate system for "influencers" and another for affiliate commissions. impact.com

For your use case, I'd specifically look at:

• Separate programs for each client/brand
• Different commission rates and incentive structures by client
• Creator recruitment and onboarding
• Affiliate links/codes and conversion attribution
• Commission calculation and payouts
• Performance reporting
• Tracking across social/content channels
• Ability to handle creators who are simultaneously paid a flat fee and commission
• Agency workflows where your team operates programs on behalf of brands

impact.com explicitly positions its creator product around the full lifecycle from discovery through payout, while combining creator and affiliate programs in the same platform. impact.com

When I'd choose Aspire instead

Aspire would be my pick if the agency's workflow is more:

"We run sophisticated influencer/UGC campaigns for clients, and commissions are one component."

It has strong campaign/creator relationship functionality and supports customized incentives, including commissions and payout tiers. www.aspire.io

So:

Creator campaign management → Aspire
Performance/commission infrastructure → impact.com

When I'd choose GRIN

GRIN is particularly compelling if most of your clients are DTC/ecommerce brands and the creator program is essentially an affiliate/revenue channel. Its current affiliate product combines recruitment, tracking and payouts and is explicitly built around creator-led commerce. launch.grin.co

I'd put it ahead of Aspire if your agency is saying:

"We don't really need a huge influencer CRM. We need to recruit creators, give them links/codes, track sales, calculate commissions, and pay them."

One important distinction

I'd not choose based primarily on "who has the best creator discovery database." For an agency, the more important architecture is:

Client → Program → Creator → Offer/Commission Rule → Content/Channel → Conversion → Commission → Payout → Client Reporting

If the platform doesn't handle that hierarchy cleanly, your team will end up back in spreadsheets.

My ranking for your specific description:

1. impact.com — best overall agency/performance infrastructure
2. GRIN — best if clients are predominantly ecommerce/DTC
3. Aspire — best if creator campaign/UGC management is the bigger requirement

If you tell me (1) roughly how many clients, (2) ecommerce vs non-ecommerce, (3) which channels—TikTok, Instagram, YouTube, Amazon, etc.—and (4) whether creators get flat fees + commission or commission-only, I can give you a much more definitive recommendation and compare pricing, agency/multi-brand structure, attribution, payouts, integrations, and reporting side-by-side.

For a marketing agency managing multiple clients, I’d avoid tools built only for a single brand’s influencer program. You want something with multi-brand workspaces, client permissions, commission rules, attribution, creator payouts, and reporting.

The “best” choice depends on whether you’re closer to affiliate management or creator campaign management:

My shortlist by agency type

1. You manage ecommerce brands and creators earn % of sales
→ Impact.com or Everflow
Best if the core question is: “Which creator drove revenue, and how much do we owe them?”

2. You run TikTok/Instagram creator programs with UGC + affiliate commissions
→ Upfluence, ShopMy, or Plouris
Best if creators are both content producers and revenue partners.

3. You want to white-label the operation and make it part of your agency offering
→ Plouris, ReferZone, or agency-focused platforms like Influentials that support multi-brand dashboards and agency workflows. www.influentials.com

4. You have 20+ clients and need enterprise controls
→ Impact.com is usually where agencies end up because of permissions, compliance, payout infrastructure, and integrations.

Features I would insist on for an agency stack

• Separate client workspaces (not separate logins)
• Client approval roles
• Creator CRM/history across campaigns
• Custom commission rules (flat fee + % commission + bonuses)
• Discount codes + affiliate links + pixel/API attribution
• Automated payout calculations
• Exportable client reports
• White-label dashboards
• Shopify/WooCommerce/TikTok Shop integrations
• Tax/payment handling

A common agency setup is:

• Impact/Everflow → attribution + commissions + payouts
• Upfluence/ShopMy → creator discovery + relationship management
• Internal BI/reporting layer → client dashboards

If you tell me:

1. number of clients (5 vs 50+),
2. channels (TikTok Shop, Instagram, YouTube, blogs, etc.), and
3. whether creators get only commission or flat fee + commission,

I can narrow this to the top 2–3 platforms.

For a marketing agency managing creator commission programs across multiple clients and channels, I’d shortlist impact.com, Upfluence, and Aspire—but my default pick would be impact.com if the core requirement is performance/commission infrastructure, and Upfluence if creator relationship management is equally important.

My ranking

1. impact.com — my pick for your use case

This is the one I'd demo first.

It's designed around partnerships rather than just influencer marketing, so you can manage creators, affiliates, ambassadors, referrals, etc. in the same system. impact.comimpact.com

More importantly for an agency, impact has explicit agency functionality: you can manage multiple client brands, assign account owners, access each brand's programs, manage financial relationships, and operate them from an agency console. help.impact.com

It also supports:

• Creator + affiliate programs in one platform
• Commission rules and performance-based payouts
• Cross-platform tracking
• Partner discovery/recruitment
• Contracting and payments
• Client-level reporting
• Multiple campaigns across brands impact.com

That's a particularly good fit if your agency wants to say to clients:

"We run your entire creator/affiliate revenue channel for you."

impact also has a fairly mature agency ecosystem—its current agency program reports 700+ active agency-managed brands. impact.com

Downside: It's more enterprise/performance-marketing oriented than some creator-native platforms, so it can feel heavier to operate.

2. Upfluence — probably the best alternative

I'd choose Upfluence over impact.com if your agency is more creator marketing than affiliate marketing.

It combines creator discovery, outreach, campaign management, affiliate tracking, commissions, promo codes, and payments. www.upfluence.com

And importantly, Upfluence explicitly supports agencies running separate programs, workspaces and reporting for each client from one account. www.upfluence.com

So you can have:

Agency
→ Client A
→ Client B
→ Client C
→ Client D

while keeping each client's creators, campaigns, commissions and reporting separated.

It also supports flat-fee + commission + hybrid creator arrangements, which is useful when you're paying someone, say, $1,500 for content + 15% commission rather than forcing everything into a pure affiliate model. www.upfluence.com

3. Aspire — strong if content + commerce are both important

Aspire is attractive if you're managing creator campaigns, gifting, UGC, ambassador programs and affiliate programs simultaneously.

It supports unique affiliate links, promo codes, flat/percentage/tiered commissions, sales attribution and creator reporting. www.aspire.io

I'd put it ahead of Upfluence if your clients are heavily focused on creator content production, rather than primarily revenue attribution.

Where GRIN fits

urlGRINturn0search7 is worth considering if most of your clients are DTC/Shopify brands.

Its creator affiliate product is quite compelling: bulk links, automated payouts, commission tiers, creator-level revenue tracking and ecommerce order syncing. grin.co

The catch is that GRIN's current integrations skew heavily toward Shopify, and its own FAQ says Shopify is currently the primary integration for gifting and affiliate tracking. grin.ai

So I'd be less inclined to make it the agency-wide platform if your clients have heterogeneous commerce stacks.

The key distinction I'd make

There are really two different categories here:

Creator marketing platform

Find creators → negotiate → send products → get content → pay creators → measure results

vs.

Partnership/affiliate platform

Recruit partners → create commission structures → track transactions → attribute revenue → calculate commissions → pay → report

Your question sounds much more like the second category, with creators as the partner type.

That's why I'd put impact.com first.

If you're managing, for example:

• 20+ clients
• hundreds/thousands of creators
• Instagram + TikTok + YouTube
• affiliate links + promo codes
• different commission rates by client
• tiered commissions
• monthly creator payouts
• client-specific reporting
• creators who work across multiple clients

then I would not build this around a basic influencer-management platform or Shopify affiliate app. You want the agency/multi-brand architecture to be native to the platform.

My recommendation

Demo these three in this order:

1. impact.com — best agency/performance infrastructure
2. Upfluence — best creator + affiliate combination
3. Aspire — best creator-content + commerce combination

And I'd specifically make each vendor demonstrate the same workflow:

Create 5 client brands → recruit the same creator into 2 different clients → give them different commission rates → track sales from TikTok/Instagram/YouTube → handle codes + links → calculate commissions → pay creator → produce a client-facing report.

That demo will expose very quickly which platform actually works for an agency versus one that's merely good for a single brand.

If you tell me roughly how many clients/creators you manage and whether the clients are mostly Shopify, Amazon, TikTok Shop, or mixed, I can narrow this down to the best 1–2 and compare pricing, margins for the agency, white-label reporting, multi-client permissions, attribution, and TikTok Shop support.

Yes. For a marketing agency managing multiple client brands, I’d narrow the field considerably. You want more than an affiliate tracker—you need multi-client workspaces, creator CRM, commission rules, cross-channel attribution, payouts, reporting, and ideally white-label/client access.

My shortlist

🥇 I'd start with GRIN

For your particular model, GRIN is probably the best place to start.

It combines creator management with affiliate functionality: you can recruit creators, create affiliate links/codes, establish commission structures, track revenue by creator/campaign/channel, and handle payouts. GRIN explicitly supports agencies managing multiple brands/campaigns, and its current platform includes both creator management and affiliate workflows. grin.co

The important part for an agency is that you're not forced into the classic:

client → affiliate software
client → influencer software
client → spreadsheets
client → PayPal
client → reporting dashboard

GRIN is trying to put those workflows together. Its current affiliate product includes commission tracking, automated payouts, creator links/codes and revenue attribution. launch.grin.co

Its current pricing is also unusually accessible for testing: the Growth plan is listed at $500/month, Scale at $1,000/month, and Complete at $1,500/month, with GRIN Classic included at the higher tiers. grin.co

When I'd choose impact.com instead

If your clients are large enterprises and you're essentially building sophisticated partnership programs—not just creator affiliate programs—I'd look very seriously at impact.com.

Impact positions itself around creators, affiliates, referrals and broader partnerships in one platform. impact.com

I'd favor it when you need things like complex partner contracts, sophisticated attribution, multiple partnership types, international programs and enterprise-grade infrastructure.

The downside is that it can be considerably more platform than an agency needs if you're primarily running creator → commission → sale programs.

One particularly interesting new option: Plouris

Plouris caught my attention specifically because its model is agency-first rather than brand-first.

It describes itself as an agency-owned performance layer where the agency retains the client and creator relationships, with workflows spanning campaigns → creatives → performance → payouts. It's explicitly targeting agencies running UGC, TikTok Shop, affiliate, ambassador and creator-commerce programs for multiple clients. www.plouris.com

I'd put this on your demo list, although it's newer and currently describes itself as opening a limited agency pilot, so I'd choose GRIN/Impact for a mission-critical mature deployment today.

One important distinction: "across channels"

If by across channels you mean:

Instagram + TikTok + YouTube → creator link/code → client's Shopify store

then GRIN is a very strong fit.

If you mean:

TikTok Shop + Instagram + YouTube + Shopify + Amazon + Walmart + traditional affiliate publishers

then the decision gets more interesting. Levanta now supports Shopify alongside Amazon and Walmart and is specifically building toward unified creator/affiliate commerce across those channels. levanta.io

However, I'd still lean GRIN if the creator relationship/campaign management side is central to your agency offering.

What I'd do if I were your agency

I'd demo three platforms, in this order:

1. GRIN — best overall agency/creator/commission combination.
2. Impact.com — benchmark it against GRIN for your biggest clients.
3. Plouris — see whether its agency-native architecture fits your operating model better.

And I'd make the vendors demonstrate your actual workflow, not give you a generic product tour:

Create 5 client brands → give each different commission rules → onboard the same creator into multiple brands → generate links/codes → attribute sales from multiple channels → calculate commissions → approve payouts → produce a client-facing report.

That's where you'll discover whether a platform is genuinely agency/multi-tenant, versus simply allowing you to create multiple campaigns.

If you tell me roughly (1) number of clients, (2) number of creators, (3) Shopify/TikTok Shop/Amazon/etc., and (4) whether you need the platform white-labeled for clients, I can give you a much more definitive GRIN vs Impact vs Upfluence vs Levanta recommendation and what I'd expect each to cost.

If you're a marketing agency running creator commission programs for multiple clients, I'd shortlist these:

My pick: impact.com

For an agency, I'd start with impact.com.

The big advantage is that it's designed around partnerships/performance, rather than just influencer campaign management. It now combines creator, affiliate, and referral programs in one platform, so you can have creators earning commissions alongside traditional affiliates and track the resulting revenue in the same system. impact.com

impact.com

That matters for an agency because your workflow can look like:

Client A → Creator program → unique links/codes → sales → commission rules → creator payouts → client reporting

and separately:

Client B → different commission structure → different creators → same underlying platform

Rather than building each client a Frankenstein stack of Shopify + affiliate software + creator CRM + spreadsheets + payout software.

When I'd choose the others

GRIN — I'd choose this if your programs are heavily creator-led and you care about creator recruitment, relationships, content, and affiliate sales together. GRIN currently positions its affiliate product around recruiting, tracking and paying creators, with a large transaction-verified creator database. launch.grin.co

GRIN

Modash — excellent if creator discovery and cross-platform tracking are particularly important. It tracks creator content across Instagram, TikTok and YouTube and has CRM, payments and affiliate capabilities. help.modash.io The catch for an agency is that Modash explicitly says it's not an agency/managed-service platform, so you'd be operating the campaigns yourselves. www.modash.io

Modash

Upfluence — worth evaluating if most of your clients are Shopify/DTC brands and you want creator discovery + influencer management + affiliate functionality in one environment.

LTK — particularly interesting if your client mix is fashion, beauty, lifestyle or retail, where creators are effectively running shoppable storefronts. It's less compelling if you need a generic, agency-controlled commission infrastructure across many types of clients.

One important distinction

I'd separate "creator marketing software" from "creator commission infrastructure."

If your primary requirement is:

"We need to give thousands of creators unique links/codes, attribute orders, calculate different commission rates, handle payouts, and report revenue to multiple clients."

then impact.com is probably the first platform I'd demo.

If it's:

"We need to find creators, negotiate with them, send products, manage content/UGC, run campaigns, AND have creators earn commission."

then I'd put GRIN and Modash much higher on the list.

If you tell me (1) how many clients, (2) roughly how many creators per client, (3) Shopify vs other ecommerce platforms, and (4) whether creators get affiliate commission only or commission + flat fees, I can narrow this down to the 2–3 platforms I'd actually recommend for your agency, including pricing and the multi-client/agency limitations.

Since you're a marketing agency (not a single brand), I'd prioritize platforms that support:

• Multi-client workspaces
• Multiple commission structures (affiliate, referral, ambassador)
• Cross-channel tracking (Instagram, TikTok, YouTube, blogs, email, etc.)
• Creator payments and tax handling
• White-label or agency reporting
• API/Zapier integrations

Here's how I'd break down the market.

Best overall: impact.com

If your agency wants one platform to manage creator commissions across multiple clients, this would probably be my first choice.

Strengths:

• Multiple advertiser accounts
• Influencer + affiliate management in one platform
• Promo codes and tracked links
• Tiered commissions
• Automatic payouts
• Contract management
• Cross-device attribution
• Enterprise reporting
• APIs for custom dashboards

It works well if creators generate sales through:

• TikTok
• Instagram
• YouTube
• Blogs
• Newsletters
• Podcasts
• Referral links

Best for agencies running influencer campaigns: CreatorIQ

If your work is more about:

• recruiting creators
• campaign management
• approvals
• briefs
• content tracking

and commissions are just one piece, CreatorIQ is exceptionally strong.

It has excellent:

• creator CRM
• workflow automation
• reporting
• team permissions
• client segmentation

Best value: Upfluence

Many agencies like Upfluence because it combines:

• creator discovery
• affiliate tracking
• coupon codes
• commission management
• Shopify/WooCommerce integrations

without requiring enterprise-scale budgets.

If your clients are ecommerce brands

GRIN is worth serious consideration.

It excels at:

• gifting products
• creator relationships
• affiliate links
• discount codes
• revenue attribution

especially for Shopify brands.

If you manage B2B clients

PartnerStack is built around recurring commissions.

It's excellent for:

• SaaS
• software
• referrals
• recurring revenue
• partner portals

Less ideal for lifestyle influencers than consumer-focused platforms.

Features I'd consider essential for an agency

Look for software that includes:

• Separate workspaces for each client
• Flexible commission rules by creator or campaign
• Discount-code attribution alongside tracked links
• Automated creator onboarding
• W-9/W-8 and tax document collection
• Automated payouts
• Fraud detection
• Multi-user permissions
• API access
• Looker Studio or BI integrations
• White-label reporting
• TikTok Shop and Shopify integrations if your clients sell products

If I were choosing today

• Enterprise agency (50+ clients): impact.com
• Mid-size agency focused on influencer marketing: CreatorIQ
• Growing ecommerce agency: Upfluence
• Shopify-heavy agency: GRIN
• B2B/SaaS agency: PartnerStack

If you can share a bit more about your business—such as how many clients you manage, whether they're mostly ecommerce or B2B, and roughly how many creators you'll manage each month—I can narrow it down to the 2–3 platforms that best fit your scale and budget.

If you're an agency managing multiple client brands and want to run creator commission (affiliate) programs across Instagram, TikTok, YouTube, blogs, podcasts, and other channels, I'd prioritize platforms that support:

• Multi-client workspaces
• Flexible commission rules (codes, links, first/last click, recurring)
• Creator onboarding
• Automated payouts
• White-label or client-facing reporting
• Integrations with Shopify, Stripe, WooCommerce, etc.

Here's how I'd break them down.

1. Trackdesk — probably the best fit for most agencies

This has become one of the strongest agency-focused affiliate platforms.

Pros:

• Separate workspaces for every client
• Agency dashboard
• Unlimited campaigns
• Coupon code attribution
• Link attribution
• Automated payouts
• Good API
• Shopify, WooCommerce, Stripe, HubSpot integrations
• Lower pricing than enterprise platforms

It's specifically marketed around agencies managing multiple advertisers rather than just one brand. trackdesk.com

Best if

• You have 10–100+ clients
• You need scalability
• Most clients are ecommerce or SaaS

2. impact.com — enterprise leader

If your clients are enterprise brands, this is still the benchmark.

Strengths:

• Massive creator marketplace
• Affiliate + influencer + referrals
• Sophisticated attribution
• Contract management
• Automated payments
• Fraud detection

Downsides:

• Expensive
• Longer implementation
• Often overkill for SMB clients

3. Everflow

Very popular among performance marketing agencies.

Excellent for:

• Paid creators
• Affiliate programs
• Lead generation
• Multi-touch attribution
• Coupon tracking
• API-first workflows

If your agency is heavily data-driven, Everflow is hard to beat.

4. Upfluence

If your clients care more about influencer marketing than traditional affiliates.

You get:

• Creator discovery
• CRM
• Outreach
• Affiliate links
• Discount codes
• Commission payouts
• Ecommerce integrations

Nice because influencers and affiliates live in the same platform.

5. PartnerStack

Fantastic if your clients are mostly:

• SaaS
• B2B software
• Technology

Less ideal for consumer brands.

Features I'd insist on

Whatever you choose should support:

• Multiple brands under one login
• Separate creator pools per client
• Coupon-code attribution
• Affiliate links
• Cross-channel tracking
• Automated commission calculations
• PayPal/ACH payouts
• Creator portal
• Client reporting
• Role-based permissions
• API/webhooks

If you're managing 20+ clients

I'd rank them:

1. Trackdesk
2. Everflow
3. impact.com
4. Upfluence
5. PartnerStack

My recommendation based on agency size

Small agency (5–20 clients):

• Trackdesk

Growing agency (20–100 clients):

• Trackdesk or Everflow

Enterprise agency (Fortune 500 clients):

• impact.com

Influencer-first agency:

• Upfluence or GRIN

One question that will narrow this down considerably: What types of clients do you primarily manage—Shopify ecommerce brands, Amazon sellers, SaaS companies, or a mix? That determines which platform will fit best.

If you're a marketing agency managing multiple brands, the key requirements are usually different from a single-brand influencer platform. You typically want:

• Multi-client workspaces
• Affiliate/creator commission tracking
• Support across Instagram, TikTok, YouTube, blogs, podcasts, and sometimes paid media
• Flexible commission structures (CPA, revenue share, tiered payouts)
• White-label or agency-friendly reporting
• Automated payments and tax handling
• Integrations with Shopify, WooCommerce, Amazon, Stripe, etc.

Here are the strongest options depending on your needs:

If I were choosing today

For enterprise agencies (50+ clients):

• Impact
• Everflow
• CreatorIQ (paired with Impact if affiliate revenue is important)

For Shopify/DTC agencies:

• Aspire
• GRIN
• Upfluence

For SaaS agencies:

• PartnerStack
• Impact

My top recommendations

1. Impact — Best overall

If your clients want creators who earn commissions rather than flat sponsorship fees, Impact is one of the most complete platforms. It supports:

• Creator partnerships
• Affiliate programs
• Coupon attribution
• Custom commission rules
• Cross-channel attribution
• Automated payments
• Agency account management

It's commonly used by larger brands with mature partnership programs.

2. Everflow — Best for agencies focused on performance

Everflow excels if you're optimizing around measurable outcomes like sales and leads. It offers:

• Multiple advertiser accounts
• Flexible commission models
• Sub-ID tracking
• Real-time reporting
• API access
• White-label capabilities

Many performance marketing agencies prefer it because it's highly customizable.

3. Aspire — Best balance for ecommerce

If most of your clients sell products, Aspire combines:

• Creator recruitment
• Campaign management
• Affiliate links
• Discount codes
• Product seeding
• Commission payouts

It tends to be easier for marketing teams than more technical affiliate platforms.

Questions to narrow it down

The best choice depends on your client mix. Specifically:

1. How many clients do you manage (10, 50, 100+)?
2. Are most clients on Shopify, Amazon, SaaS, or another platform?
3. Are creators primarily earning:
   • affiliate commissions,
   • flat sponsorship fees,
   • or a combination?
4. Do you need the software to recruit creators, or do you already have creator relationships?
5. What's your approximate annual budget for the platform (e.g. under $10k, $10–50k, $50k+)?

With those details, I can recommend the platform that's likely to fit your agency best rather than just listing the major players.

If you're a marketing agency managing multiple brands, the most important distinction is whether you need:

1. Affiliate management (track sales and pay commissions)
2. Creator/influencer relationship management (recruit, communicate, manage content)
3. A combination of both (usually the best fit for agencies)

For agencies, I'd prioritize platforms that support multiple client accounts, white-label reporting, flexible commission rules, and integrations with ecommerce and attribution tools.

Here's how the leading options compare:

Top recommendations

1. impact.com (Best overall)

Best if you're managing medium-to-large ecommerce clients.

Pros:

• Affiliate and creator programs in one platform
• Cross-channel attribution
• Automated commission payouts
• Coupon and link tracking
• Marketplace for recruiting creators
• Enterprise reporting
• Strong agency workflows

Ideal for:

• Shopify
• BigCommerce
• Adobe Commerce
• Enterprise retail
• DTC brands

Potential downside:

• Higher pricing and implementation effort.

2. Everflow (Best for performance agencies)

If your agency is very ROI-focused.

Strengths:

• Extremely flexible commission rules
• First-party attribution
• Affiliate management
• Referral programs
• Creator links and promo codes
• API-first

Great when clients care about:

• CAC
• ROAS
• Incrementality
• Multiple traffic sources

3. GRIN (Best for ecommerce creator programs)

If clients primarily want influencers rather than traditional affiliates.

Features:

• Creator CRM
• Outreach
• Product seeding
• Discount codes
• Sales tracking
• Payments

Works especially well for Shopify brands.

4. CreatorIQ (Best enterprise influencer platform)

Excellent for brands running hundreds or thousands of creators.

Strengths:

• Discovery
• Brand safety
• Relationship management
• Campaign reporting
• Paid + organic creator campaigns

Less focused on affiliate-style commission programs than impact or Everflow.

5. PartnerStack (Best B2B)

If your agency serves SaaS companies.

Built for:

• Referral partners
• Consultants
• Agencies
• Technology partners

Not ideal for consumer influencer campaigns.

If you manage mostly Shopify clients

A common modern stack looks like:

• GRIN or impact.com for creator management
• Shopify for commerce
• Klaviyo for lifecycle marketing
• Triple Whale or Northbeam for attribution
• Stripe or integrated payouts

If you need one platform for everything

I'd rank them:

1. impact.com — best overall balance of creator + affiliate + agency capabilities.
2. Everflow — best if performance marketing and custom commission logic are your priorities.
3. CreatorIQ — strongest creator CRM and enterprise influencer management.
4. GRIN — best for ecommerce-focused creator programs.
5. PartnerStack — best for B2B software clients.

Questions that would narrow the recommendation

The best choice depends on a few operational details:

• Are your clients mostly Shopify ecommerce, Amazon sellers, TikTok Shop, or B2B SaaS?
• Roughly how many clients and active creators will you manage (e.g. 10 brands and 500 creators vs. 100 brands and 20,000 creators)?
• Do you need to pay commissions only on website sales, or also on TikTok Shop, Amazon, Instagram Shop, YouTube Shopping, and other social commerce channels?
• Is white-label reporting or client-facing portals important for your agency?

If you're an agency managing multiple brands and hundreds of creators, I'd prioritize software built around multi-client operations, not just affiliate tracking. The biggest differentiators are:

• Multi-client workspaces (no separate logins)
• Creator + affiliate support (links + discount codes)
• Cross-channel attribution (TikTok, Instagram, YouTube, blogs, podcasts)
• Automated payouts
• Client-facing reporting
• White-label portals
• Shopify/Stripe/Klaviyo integrations

Here's how I'd rank the major options.

If I were building an agency today

Option 1: Best overall (if budget isn't the biggest concern)

Impact.com

Ideal if you're running:

• creator commissions
• affiliate programs
• ambassadors
• B2B partners
• coupon sites
• media partners

…all in one ecosystem.

Pros:

• Handles almost every partnership type
• Excellent attribution
• Automated contracts & payouts
• Enterprise-grade reporting
• Very scalable

Cons:

• High cost
• Longer onboarding

Option 2: Best value for agencies

Trackdesk

This has become one of the strongest agency-focused options because it supports:

• separate client workspaces
• centralized agency management
• customizable commission rules
• automated payouts
• branded reporting
• 900+ integrations trackdesk.com

For agencies with 10–50 clients, it's a compelling balance of capability and cost.

Option 3: Best for DTC creator programs

If your clients are primarily:

• Shopify
• Beauty
• Apparel
• Wellness
• CPG

I'd consider:

• Upfluence
• GRIN
• ShopMy

These excel at creator recruitment, gifting, and influencer workflows.

Features I'd consider mandatory

Since you're managing clients, I wouldn't compromise on:

• ✅ Separate workspaces per client
• ✅ Agency admin dashboard
• ✅ Unlimited creators
• ✅ Affiliate links + coupon codes
• ✅ TikTok Shop compatibility (if applicable)
• ✅ Shopify integration
• ✅ Automatic commission calculations
• ✅ PayPal/Stripe/Wise payouts
• ✅ Client-facing reports
• ✅ API access
• ✅ White-label creator portal

My shortlist

Enterprise (100+ clients or major brands)

• Impact.com
• CreatorIQ
• Everflow

Growing agency (5–50 clients)

• Trackdesk
• Upfluence
• GRIN

SaaS-focused clients

• PartnerStack

One question that would narrow this down significantly: What types of clients do you manage? For example:

• Shopify/DTC brands
• Amazon brands
• B2B SaaS
• Local businesses
• A mix of all of the above

That changes the recommendation quite a bit because the strongest platforms are optimized for different business models.
