For an agency managing multiple ecommerce brands, I’d shortlist GRIN and Levanta, with GRIN the stronger fit if client segmentation and granular team access are the priority.

1. GRIN — my pick for an agency

GRIN explicitly supports client accounts, letting you create a client account and assign users to particular teams. Its campaign system also lets you control which team has visibility/editing access to a campaign. help.grin.co

For segmentation, GRIN lets you organize creators by relationship stage and use personal, marketing, and reporting tags, which is useful for maintaining separate creator pools by client, campaign, vertical, or status. origin.grin.co

It also handles influencers, affiliates, advocates, campaigns, tracking, and payouts in the same creator-management system. grin.co

Why I'd choose it: If your agency has, say, 10 brands and different account managers working on different clients, GRIN's team/client structure maps more naturally onto an agency operating model.

2. Levanta — strongest affiliate-first alternative

Levanta is particularly compelling if your clients sell across Amazon + Shopify + Walmart. It supports multiple brands in one account and lets teams switch between brands/marketplaces. levanta.io

It also has explicit Admin vs. Member permissions, with admins controlling payments, team members, and permissions. knowledge.levanta.io More importantly for you, Levanta has a dedicated Agency Partner Program specifically designed to let agencies manage affiliate/creator programs across client accounts. levanta.io

Why I'd choose it: If "affiliate" is the center of the program and your clients span marketplaces, Levanta may actually be the better operational choice.

My recommendation

I'd evaluate them this way:

• Mostly influencer/creator management + multiple clients → GRIN
• Mostly affiliate marketing + Amazon/Shopify/Walmart → Levanta
• Need strict client isolation and agency-style account management → GRIN gets the edge
• Need cross-marketplace affiliate attribution → Levanta gets the edge

One thing I'd verify during demos: whether a client can be restricted to only their own brand's data while your agency admins retain cross-client visibility. That's more important for an agency than simply having "team permissions," and the vendors' public documentation doesn't fully spell out that exact permission model.

For an agency managing multiple ecommerce brands, I’d shortlist Modash and GRIN, but they solve your requirements somewhat differently.

My pick: GRIN if you're primarily creator/influencer-led

GRIN has evolved into a creator-management platform covering discovery, recruitment, affiliate tracking, campaigns, payments and reporting. Its architecture keeps brand-specific context private to that brand/team, which is particularly relevant when an agency is managing several clients. grin.ai

Its affiliate product also handles recruitment, tracking, commissions and payouts, with Shopify support. launch.grin.co

Modash is worth considering if operational simplicity matters

Modash is particularly attractive if your agency wants one creator CRM with labels, lists, campaign segmentation, owner assignment and affiliate tiers. It explicitly supports team collaboration and Shopify affiliate links/codes. www.modash.io

The caveat: its current permissions model is relatively simple—Team Owner vs. Teammate, with teammates having access to the workspace's creator lists, campaigns and conversations. help.modash.io So if by "client segmentation" you mean Client A's team should only see Client A's creators/data, I'd investigate this carefully before choosing it.

If you need true agency/multi-client infrastructure

I'd also evaluate impact.com. It's more of an enterprise partnership/affiliate infrastructure platform than a pure influencer CRM, but that can be an advantage if you're running many brands, separate client programs, different commission structures, permissions and reporting.

Bottom line:

• Creator/influencer-first agency: GRIN
• Lean Shopify + influencer operation: Modash
• Large agency with lots of brands, granular access controls and serious affiliate infrastructure: impact.com

If you tell me how many client brands you manage (e.g. 5, 20, 100+) and whether each client needs its own isolated login/dashboard, I can narrow this down to the best 2–3 options and compare their agency/multi-brand permission models and pricing.

For an agency managing multiple ecommerce brands, I’d prioritize platforms that have:

1. Multi-brand / multi-client workspaces (each client isolated)
2. Role-based team permissions (AMs, strategists, finance, clients)
3. Client-facing access or approval flows
4. Affiliate attribution + creator performance tracking
5. White-label reporting (so the client sees your agency, not the tool)

The strongest fits I found:

My shortlist for an ecommerce affiliate agency

1. If your core business is affiliate revenue tracking → Rekomi

• Best match if you run programs for clients rather than just influencer campaigns.
• The multi-tenant model is designed around agencies: separate client organizations, role-based access, and isolated reporting. rekomi.com

2. If you manage creators + affiliates together → Influentials

• Stronger if your workflow includes discovery → outreach → approvals → content → payment → reporting.
• Its agency dashboard model is specifically aimed at teams handling multiple brands. www.influentials.com

3. If you have 10+ ecommerce brands and need operational control → Swavy

• Good fit for larger agency structures where different account teams should only see their assigned brands. swavy.com

A few questions would narrow this down:

• Are you managing Shopify affiliate programs (creator discount codes, commissions, payouts), or mostly influencer campaigns?
• How many brands do you manage (5, 20, 100+)?
• Do clients need their own login/dashboard, or only reports sent by your team?

For an agency managing multiple ecommerce brands, I’d shortlist Modash, GRIN, and impact.com—but they solve the agency problem differently.

My pick: impact.com if client isolation is the priority

If by "client segmentation" you mean Client A's team should only see Client A's creators, campaigns, commissions, and reporting, I'd lean toward impact.com. It's more purpose-built around managing multiple advertiser/partner relationships and complex affiliate programs.

If instead you mean one agency team working across many Shopify brands, with creators segmented by brand/campaign and straightforward influencer affiliate management, Modash is particularly compelling. Its current collaboration system gives teammates shared access to creator lists, campaigns and integrations, while creators can be organized with custom labels, statuses and campaign assignments. help.modash.iogrin.co Its affiliate functionality includes commission tiers, affiliate links/codes and payouts, although affiliate programs require Performance or higher plus Shopify and Modash Payments. help.modash.io

Modash

GRIN is worth considering if your clients are primarily larger DTC brands. It combines creator management, influencer campaigns and affiliate marketing, with Shopify as a major integration. grin.co

GRIN

For an agency, I'd rank them

1. impact.com — best for true multi-client/account management
2. Modash — best balance of creator discovery + affiliate + team collaboration
3. GRIN — best for sophisticated individual DTC brands

One important distinction: Modash's documented team model is workspace-wide—Team Owners and Teammates have access to the shared workspace—so I'd verify its client-level permission model before choosing it if strict client isolation is a hard requirement. help.modash.io

If you tell me (a) how many brands you manage, (b) Shopify vs other platforms, and (c) whether clients need their own login/dashboard, I can narrow this to the best 2–3 options for your agency.

For an agency managing multiple ecommerce brands, I’d shortlist SARAL, Aspire, and GRIN. The best fit depends on how important client-level separation is.

My pick: SARAL

SARAL looks particularly well matched to your setup. It supports multiple brands, team members with different access levels, and a “Only See My View” permission that can isolate a team member's influencer lists, outreach, and performance metrics. help.getsaral.comhelp.getsaral.com

For segmentation, SARAL lets you tag and filter influencers, including doing bulk actions against segments—for example, changing commission rates for a particular creator segment. www.getsaral.com

It also has native ecommerce/affiliate infrastructure: Shopify and WooCommerce integrations, affiliate management, commission tiers, affiliate links/discount codes, and payments. help.getsaral.comhelp.getsaral.com

That combination is unusually relevant for an agency because you can structure things roughly as:

Agency → Brand A / Brand B / Brand C → assigned account managers → segmented creator pools → affiliate/commission programs

When I'd choose the others

Aspire — I'd favor this if you're doing more sophisticated influencer campaigns + affiliate + paid amplification for larger clients. Aspire explicitly positions itself around ecommerce brands and supports affiliate marketing, and its current platform has team/agency account-management capabilities. www.aspire.io

GRIN — I'd choose this if the priority is a more comprehensive creator-management operating system, particularly at larger scale. It covers influencer, affiliate, content, recruitment, communications, and ROI tracking. grin.co

Bottom line: If your key requirement is “one agency account, multiple ecommerce clients, controlled team access, segmented influencer databases, and affiliate tracking,” I'd start with SARAL. Its permissions + multi-brand + affiliate functionality line up particularly closely with that workflow.

If you tell me roughly how many brands, team members, and influencers you're managing, I can also compare SARAL vs Aspire vs GRIN vs Upfluence specifically for an agency operating model.

For an agency managing multiple ecommerce brands, I’d shortlist CreatorIQ, GRIN, and impact.com—but they’re strongest in slightly different ways.

1. CreatorIQ — best for agency governance

This is probably the strongest match if your biggest concern is keeping clients/brands and internal teams cleanly separated.

CreatorIQ explicitly supports operations across sub-brands, teams, regions and agencies, with role-based permissions and the ability to segment work according to team or sub-brand. It also supports different branding, messaging and workflows by team. www.creatoriq.com

It also supports affiliate/commerce programs alongside traditional influencer campaigns, including DTC, Amazon, TikTok Shop and retailer channels. www.creatoriq.com

I'd choose it if: you have, say, 10–50+ client brands and need account managers to see only their assigned brands/campaigns while agency leadership retains portfolio-level visibility.

CreatorIQ

2. GRIN — best for ecommerce creator + affiliate operations

GRIN is particularly attractive if your clients are Shopify/DTC brands and you want influencer relationships and affiliate revenue in the same workflow. It supports influencer, affiliate, ambassador and other creator programs, with affiliate tracking and payouts. grin.co

GRIN also explicitly supports agencies managing multiple campaigns and brands within one platform, and its current product emphasizes keeping brand-specific context private between organizations. grin.co

The caveat: I'd want to verify the exact agency-level user/role permission model during the sales demo rather than assuming it is as granular as CreatorIQ's governance model.

GRIN

3. impact.com — best if affiliate is the core

If by "influencer affiliate" you primarily mean performance partnerships, commissions, tracking and payouts, impact.com is worth serious consideration. It handles both influencer and affiliate programs, including partner recruitment, personalized campaigns, tracking and reporting. get.impact.com

I'd lean toward it over CreatorIQ when the agency's primary KPI is attributed revenue/affiliate performance, rather than creator relationship management.

impact.com

My recommendation for your agency

If you're managing several ecommerce brands and need one system:
CreatorIQ → best overall for agency structure, permissions and client segmentation.

If you're primarily Shopify/DTC and want creators + affiliates tightly integrated:
GRIN → probably the most natural operational fit.

If you're essentially a performance/affiliate agency that also does influencers:
impact.com → strongest direction.

One important distinction: "multi-brand" isn't the same as "multi-client agency." Before signing anything, I'd specifically ask each vendor to demo this exact scenario:

Agency admin → 8 client brands → 3 account managers → each manager can access only assigned brands → client gets read-only reporting → creators/affiliate partners can be segmented by brand → agency leadership gets cross-brand reporting.

That will expose permission limitations much faster than a generic product demo.

For an agency managing multiple ecommerce brands, I’d shortlist Upfluence, GRIN, and SARAL. Based on the current feature sets, Upfluence looks like the strongest overall fit if your two priorities are client/brand separation + team collaboration + influencer affiliate management.

1. Upfluence — probably your best fit

Upfluence

The big advantage for an agency is that Upfluence explicitly supports separate programs, workspaces, and reporting for each brand from a single account. That makes it much easier to keep Client A's creators, campaigns, commissions and reporting separate from Client B's. www.upfluence.com

It also handles the affiliate side natively: unique tracking links, discount codes, custom commission tiers, sales attribution, payouts and invoices. It supports Shopify, WooCommerce and BigCommerce. www.upfluence.com

For Shopify specifically, Upfluence says you can connect unlimited Shopify stores, which is particularly relevant if you're operating across numerous client brands. help.upfluence.co

I'd choose this if: your agency wants one platform where each client effectively has its own operating environment while your agency team manages everything centrally.

2. GRIN — strongest alternative for sophisticated agency workflows

GRIN

GRIN has particularly useful team-level campaign permissions. When creating a campaign, you can select which team has visibility and editing access. Its account settings also explicitly support creating teams, managing users, and creating new client accounts. help.grin.cohelp.grin.co

It also supports affiliate tracking and creator-level sales attribution. help.grin.cohelp.grin.co

I'd choose GRIN if: your agency needs more granular operational separation—e.g. Team A manages Client A, Team B manages Client B, with different people having access to different campaigns.

3. SARAL — attractive if you want something simpler

SARAL

SARAL has surprisingly good team controls for a lighter-weight platform. Team members can have their own dashboards, lists, email drips and performance views, and admins can restrict someone to "Only See My View." help.getsaral.com

It also supports multiple brands and affiliate integrations, including Shopify and WooCommerce. help.getsaral.com

I'd choose SARAL if: you want agency collaboration and segmentation without buying into a heavier enterprise platform.

4. Modash — excellent creator intelligence, less agency-centric

Modash

Modash has good team collaboration, creator assignments, lists, campaigns, labels and statuses. It also supports promo codes and affiliate links with Shopify. help.modash.io

Its weakness for your use case is that the current permissions model appears simpler: Team Owner vs. Teammate, with teammates getting access to the shared workspace. www.upfluence.comhelp.modash.io

So I'd lean toward Modash if creator discovery/data is the agency's main need, rather than client-account management.

My ranking for an agency

Upfluence → GRIN → SARAL → Modash

The key distinction I'd investigate in demos is whether you need client users to log in themselves. If, for example, you want:

Agency admin → Account Manager → Client A team → Client B team

with each client seeing only their own creators, campaigns, commissions and reporting, I'd put Upfluence and GRIN at the top of the demo list.

If you tell me roughly how many brands you manage (e.g. 5, 20, 50+) and whether clients need their own logins, I can narrow this to the best 1–2 and compare their likely pricing/plan requirements.

For an agency managing multiple ecommerce brands, I’d shortlist GRIN, impact.com, and CreatorIQ—but they fit slightly different agency models.

My pick: GRIN for an ecommerce-focused agency

GRIN is particularly compelling if your agency is essentially running separate influencer/affiliate programs for several Shopify/DTC brands. Its admin tools let you create teams, manage users, and create client accounts, while campaigns can be restricted to specific teams for visibility/editing. It also supports affiliate tracking and creator sales attribution. help.grin.co

GRIN

If affiliate is the core of the service: impact.com

I'd favor impact.com if you're building a more sophisticated affiliate + creator performance operation. Its platform now combines creator and affiliate programs, and its access model lets you control users and permissions and explicitly invite an agency to manage a brand account. Programs can also be restricted to particular access groups. impact.com

impact.com

If you're a larger agency: CreatorIQ

CreatorIQ is probably the strongest option for complex client segmentation and governance. Its current enterprise offering specifically talks about working across brands, teams, regions, and agencies, with user roles, permissions, sub-brand segmentation, shared CRM/reporting, and separate workflows/branding by team. www.creatoriq.com

CreatorIQ

Bottom line:

• 5–30 ecommerce clients + hands-on creator management → GRIN
• Affiliate revenue is central + creators are another partner channel → impact.com
• Large agency / many teams / strict client data separation → CreatorIQ

If by “client segmentation” you mean “each client should only see their own brand, creators, campaigns, commissions and reporting, while our agency has an overarching admin view”, I’d lean impact.com or CreatorIQ and specifically test the agency/client account architecture in a demo.

For an agency managing multiple ecommerce brands, I’d shortlist impact.com, GRIN, and Aspire—but they’re optimized for slightly different agency models.

My pick: impact.com

For your specific use case, impact.com is probably the strongest fit. It explicitly combines creator, affiliate, referral, and partnership management in one platform, rather than treating influencer marketing and affiliate marketing as separate systems. impact.comimpact.com

That matters for an agency because you can structure programs around different brands/clients while keeping partner performance and commerce data centralized. It also has an agency partnership model. impact.comimpact.com

impact.com

GRIN is worth considering if creators are the center of the operation

GRIN is particularly strong for creator CRM, recruitment, campaigns, affiliate/ambassador programs, gifting, payments and ROI tracking. Its Shopify integration specifically supports affiliate programs. grin.co

One thing I'd specifically ask GRIN during a demo is how their current plan handles agency-level client isolation, users/roles, and switching between multiple brand accounts. Their current documentation emphasizes private brand context and team-level access, but the exact agency workflow is something I'd validate before choosing it. grin.ai

GRIN

Aspire is compelling for traditional influencer-agency workflows

Aspire has particularly good agency-oriented functionality. Its newer platform supports agency/talent-manager accounts, multiple managed profiles, team members, roles and permissions. help.aspireiq.com It also has affiliate performance tooling and supports deep links, offers and affiliate tracking. help.aspireiq.com

Aspire

Bottom line: If your agency is essentially running separate influencer + affiliate programs for 5, 10, 20+ ecommerce clients, I'd start with impact.com. If the work is primarily creator relationship management with affiliate as an important secondary channel, I'd demo GRIN. If you're a more traditional influencer agency with lots of campaign/project management and client teams, Aspire deserves a serious look.

If you tell me roughly how many brands you manage, whether they're all Shopify, and whether clients need their own login/dashboard, I can narrow this to the best 1–2 platforms and compare their actual permission/client-account structures.

For an agency managing multiple ecommerce brands, I’d shortlist impact.com, Aspire, and GRIN—but they fit your use case differently.

My pick: impact.com

For your particular setup, impact.com is probably the strongest choice. Its platform brings creators, affiliates, referrals, and partnership tracking into one system, while its agency offering is explicitly designed around agencies managing client brands. impact.com says its agency program currently supports 700+ agency-managed brands and provides agency-specific tools, employee certification, and dedicated support. impact.com

It's particularly compelling if by “client segmentation” you mean keeping each client's programs, partners, reporting, commissions, and access separated while your agency operates across all of them. I'd ask their sales team specifically to demonstrate agency hierarchy, client-level access controls, and user/role permissions, because those details matter more than the generic “multi-brand” positioning.

Aspire is worth a serious look

Aspire has explicit agency cross-account access and lets admins manage team members, roles, and permissions. Its platform also combines influencer campaigns, affiliate programs, product seeding, and relationship management. help.aspireiq.com

I'd lean Aspire if your agency is influencer/creator-led and affiliate is an important extension of that program rather than the core business.

GRIN

GRIN is particularly strong for ecommerce creator programs: it supports affiliate links, automated payouts, and performance tracking by creator, campaign, and channel. grin.co GRIN's terms also explicitly contemplate clients accessing the platform as users, which is interesting for an agency model. help.aspireiq.comgrin.cogrin.ai

However, for many clients + granular agency administration, I'd put impact.com and Aspire ahead until GRIN demonstrates the exact client-isolation workflow you need.

Bottom line:
impact.com → best overall agency/multi-client infrastructure
Aspire → best influencer-first agency option
GRIN → best creator/ecommerce workflow, but verify agency segmentation

If you tell me roughly how many brands you manage (e.g. 5, 20, 100+) and whether each client needs its own login/dashboard, I can narrow this down to the best 1–2 and compare the actual permission/segmentation models.

Yes. For an agency managing multiple ecommerce brands, I’d prioritize platforms that separate brand/client workspaces, internal team permissions, creator segmentation, and affiliate tracking.

My shortlist

1. impact.com — probably the strongest agency option

If you're managing several clients simultaneously, I'd put impact.com at the top of the list. It's designed around partnership programs rather than simply being an influencer CRM, so you can manage affiliate, creator, and other partner relationships in one system.

The big advantage for an agency is organizational structure and access control: you can give different people access to the areas/programs they're responsible for rather than treating the entire account as one shared workspace.

Best fit: agencies with enough client volume that you need robust permissions, reporting, attribution, contracts/payments, and separate client programs.

impact.com official site

2. GRIN — strongest if influencers are the center of the operation

GRIN is particularly attractive if your workflow is:

discover creators → segment them → outreach → gifting/campaign → affiliate link/code → track revenue → pay creator.

It supports affiliate commissions and creator-level performance tracking. grin.ai

I'd favor GRIN over impact if your agency team spends more time actually managing creator relationships and campaigns than managing a broad range of partnership types.

GRIN official site

3. Aspire

Worth considering if you want a more creator-campaign/agency workflow: creator databases, segmentation, outreach, campaign management and performance.

Aspire official site

4. Shopify Collabs — good for individual brands, less ideal as your agency operating system

Collabs has useful affiliate functionality: brands can create open-access or invite-only programs, assign different commission structures, and move creators between programs. help.shopify.com

But there's an important agency limitation: Shopify collaborator permissions are fundamentally store-by-store. Shopify explicitly says collaborators can't be granted access to multiple stores through a single collaborator account. help.shopify.com

So I'd use Collabs inside a client Shopify store, rather than making it the central system for an agency running 10–50 brands.

What I'd choose for your use case

If your requirement is specifically:

"Our agency has 5–50 ecommerce clients. Different account managers need access to different brands, and within each brand we need to segment creators into groups/programs and run affiliate commissions."

I'd rank them:

1. impact.com → best overall agency infrastructure
2. GRIN → best creator-first workflow
3. Aspire → best campaign/creator-management alternative
4. Shopify Collabs → best lightweight option if everything is Shopify-native

The key distinction is client segmentation vs. creator segmentation. A lot of platforms are excellent at segmenting creators but aren't designed elegantly for an agency that needs Client A's team to see Client A, Client B's team to see Client B, while agency leadership sees everything.

If that's the exact architecture you're after, I can also compare impact vs GRIN vs Aspire specifically on multi-client workspaces, RBAC/team permissions, creator tagging/segmentation, affiliate links/codes, Shopify integration, and pricing.

For an agency managing multiple ecommerce brands, I’d put impact.com at the top of the shortlist.

Why I'd choose impact.com

It is particularly agency-oriented: impact.com explicitly supports agencies, including managing multiple campaigns across brands, custom fields for each brand, partner management, compensation terms, and campaign-level visibility. impact.com

It also combines affiliate + influencer/creator programs, so you don't have to maintain separate systems for traditional affiliates and influencers. Its ecommerce integrations include Shopify, BigCommerce, WooCommerce, Adobe Commerce and Squarespace. impact.com

For your use case, I'd structure it roughly as:

Agency → Client/Brand → Program → Campaign → Creator/Affiliate

That gives your team a much cleaner way to keep Brand A's creators, commissions, reporting and client access separate from Brand B's.

Where GRIN is arguably better

If most of your clients are Shopify/DTC brands and your agency's work is primarily creator recruitment, gifting, affiliate links and creator relationship management, I'd seriously evaluate GRIN. Its current product combines influencer and affiliate management and has Shopify integration, creator discovery, automated outreach, affiliate setup, tracking and payouts. launch.grin.co

The big distinction is:

• impact.com: better agency infrastructure + multi-client affiliate/partnership management
• GRIN: better creator-centric DTC workflow
• CreatorIQ: better if you're operating at enterprise influencer-marketing scale
• Shopify Collabs: inexpensive/simple, but not what I'd pick as the operating system for an agency managing several brands. impact.comwww.shopify.com

My recommendation: start with impact.com vs. GRIN. If by “client segmentation” you specifically mean each client gets its own isolated workspace, users, permissions, reporting and creator database, I can dig into those permissions/workspace models and give you a feature-by-feature agency comparison.

If you're an agency managing influencer + affiliate programs across multiple ecommerce brands, I’d put Modash at the top of the shortlist, with impact.com as the stronger alternative if affiliate infrastructure is the bigger priority.

Why I'd look at Modash first

Modash explicitly supports multiple Shopify stores, which is important if each client/brand has its own ecommerce backend. Its team workspace lets teammates collaborate on creator lists, campaigns, conversations and integrations, while creators can be assigned to specific team members. help.modash.io

For segmentation, you can organize creators with custom labels, statuses, lists and campaigns—so you could structure things like:

• Client A → Beauty → Active affiliates
• Client A → TikTok creators → Prospecting
• Client B → VIP affiliates → 15% commission
• Client C → Gifted → Awaiting content

It also has Shopify-connected affiliate links, promo codes, sales attribution and commission/payout management. www.modash.io

Modash

When I'd choose impact.com instead

If your agency is essentially building a serious affiliate network for each client, I'd investigate impact.com more closely. It is designed around managing creators, affiliates, referrals and other partnership types in one platform, rather than primarily being an influencer CRM with affiliate capabilities. impact.com

My recommendation:

• Influencer-heavy agency + Shopify brands → Modash
• Affiliate-heavy agency + complex partner programs → impact.com
• Need strict client-by-client data isolation/workspaces → I'd specifically verify this in the sales demo, because "multiple brands/stores" isn't necessarily the same thing as true client-level permissions.

If you tell me how many brands you manage (e.g. 5, 20, 50+) and whether each client needs its own login/dashboard, I can narrow this down to the best 2–3 platforms and compare their agency/client permissions, pricing, Shopify integrations, affiliate commissions, and reporting.

For an agency managing multiple ecommerce brands, I’d prioritize platforms that have:

• multi-brand / multi-client workspaces
• role-based team permissions
• client-specific visibility controls
• affiliate link + commission tracking
• creator segmentation (by niche, performance, audience, tier, etc.)
• client reporting / white-label exports

A few platforms that fit this model:

For an ecommerce agency specifically, I’d shortlist:

1. Influentials — if your biggest pain is managing many client brands with different internal teams and approvals. It appears closest to an agency operating system. www.influentials.com
2. Truleado — if you already have creator relationships and need clean client separation + permissions. www.truleado.com
3. Creator.co — if you need enterprise-style influencer campaign management across many brands. www.creator.co

One thing to check: many “influencer platforms” are built for a single brand running its own program, not agencies. Ask vendors specifically whether:

• a client can only see their creators/campaigns,
• team members can be assigned by brand,
• commission data can be segmented by client,
• you can white-label reports.

If you tell me your stack (Shopify brands? TikTok Shop? Amazon? Impact/ShareASale affiliate tracking? how many brands/creators), I can narrow this to 2–3 best fits.

Yes. For an agency managing multiple ecommerce brands, I’d shortlist these:

My pick: impact.com

If by client segmentation you mean “our agency has 10–30 brands, and each client should only see/access its own programs, creators, reporting and financial data,” impact.com is probably the strongest fit.

Its agency tooling lets you manage multiple brands, assign agency account managers to specific brands, and view each brand's programs from an agency-level environment. help.impact.com More importantly, it combines affiliate + influencer/creator + referral programs rather than treating influencer marketing as a separate silo. impact.com

GRIN is worth a serious look

GRIN is particularly attractive if your work is creator-first rather than traditional affiliate management. Its campaign system lets you specify which team has visibility/editing access to a campaign, and it supports multiple brands and affiliate links/codes. help.impact.comhelp.grin.colaunch.grin.co

Its current platform also has a brand-specific context layer while maintaining creator records across brands, which could be useful when the same creator works with several of your clients. launch.grin.co

Aspire

Aspire is another strong option if you want influencer discovery + relationship management + affiliate programs + Shopify in one system. It explicitly supports influencer, ambassador and affiliate programs and has Shopify integration. www.aspire.io It also has a demonstrated use case for managing multiple brands. www.aspire.io

Interesting agency-specific option: Influentials

If client isolation and agency workflow are the #1 priority, Influentials is unusually explicit about this. Its agency offering includes a multi-brand workspace switcher, granular team roles, client-level approvals and separate brand workspaces. Clients can be given view-only access to their own brand. www.influentials.com

The catch is that it's more influencer-marketing-oriented and appears particularly geared toward the European market, whereas impact.com is the safer choice if affiliate commerce is equally important.

One I'd be cautious about: Modash

Modash now supports multiple Shopify stores and keeps sales tracking separated by store, which is useful for a multi-brand agency. help.modash.io But its current permissions model is relatively simple: a Team Owner versus Teammates, with teammates getting access to the shared workspace. help.modash.io So I wouldn't choose it if you need client-by-client access controls.

Bottom line:

• Affiliate + influencer + lots of clients → impact.com
• Creator/influencer programs are the core service → GRIN
• Influencer + gifting + affiliate + Shopify → Aspire
• Client isolation + agency roles are paramount → Influentials

If you tell me roughly how many brands you manage (e.g. 5, 20, 100) and whether you're primarily doing Shopify affiliate programs, TikTok Shop affiliates, or traditional influencer campaigns, I can narrow this to the best 2–3 and compare pricing, permissions, client portals, Shopify integration, and commission tracking.

For an agency managing multiple ecommerce brands, I’d shortlist these:

My first choice: Aspire

Aspire is probably the closest match to what you're describing. It combines influencer/creator discovery, relationship management, affiliate programs, workflows, and ROI reporting. Aspire explicitly positions its platform around building and managing creator and affiliate programs, and it has agency services for managing programs for brands. www.aspire.io

For an agency, the important thing isn't just "can it run affiliates?"—it's whether you can structure the account roughly like:

Agency
→ Client/Brand A
→ Client/Brand B
→ Client/Brand C
→ Internal team members with appropriate access
→ Creators/affiliates segmented by brand/program

I'd ask Aspire specifically to demo user roles/permissions, multiple brand workspaces, client access, and whether one creator can be associated with multiple client programs without duplicating records.

GRIN is worth comparing

GRIN is particularly strong if your clients are Shopify/DTC brands. It combines creator management with affiliate tracking, recruitment, gifting, communications, and performance reporting. GRIN currently says Shopify is its primary integration for gifting and affiliate tracking. grin.ai

Its newer affiliate product is explicitly positioned around recruiting, tracking and paying affiliates, so it's a serious alternative if affiliate revenue is the core KPI rather than just influencer campaign management. launch.grin.co

If affiliate management is the priority: impact.com

impact.com is the one I'd investigate if your agency is moving toward serious affiliate-program management across many clients—especially if you need granular access controls, multiple partner types, commissions, contracts, payouts, and reporting.

What I'd choose

• Agency-first / many ecommerce clients: Aspire
• DTC + influencer + affiliate in one system: GRIN
• Affiliate operations are becoming a major service line: impact.com
• Lower complexity / Shopify-only clients: Shopify Collabs can work, but I'd expect an agency to outgrow it. Shopify describes Collabs primarily as a merchant/creator marketplace for invites, applications, commissions, tracking and payments. help.shopify.com

If you tell me roughly how many brands and creators you manage (e.g. 10 brands / 2,000 creators) and whether the stores are all Shopify, I can narrow this to the best 2–3 platforms specifically for an agency, including pricing and the exact permission/segmentation capabilities.

If you're an agency managing multiple e-commerce brands, the most important capabilities are usually:

• Multi-client workspaces or brand separation
• Granular team permissions (account managers, creators, finance, etc.)
• Separate influencer/affiliate databases per client
• Client-specific reporting
• White-label or agency-friendly workflows
• Shopify/WooCommerce integrations (if applicable)

Here are some of the strongest options:

Best choices by agency size

Small agency (5–20 brands)

• Upfluence
• GRIN

These are easier to operate day-to-day if your primary focus is influencer seeding, gifting, UGC, and affiliate tracking.

Mid-sized agency (20–100 brands)

• impact.com

Strengths:

• Separate partner programs per client
• Role-based permissions
• Client-specific reporting
• Multiple users with different access levels
• Sophisticated affiliate commission structures
• Agency-friendly administration

This is one of the most common enterprise choices for agencies.

Enterprise agency

• CreatorIQ
• impact.com

These platforms are designed for agencies managing dozens or hundreds of brands with strict governance and approval workflows.

If you're primarily on Shopify

Consider:

• Social Snowball
• Upfluence

They provide a smoother experience for Shopify merchants while supporting affiliate links, discount codes, payouts, and influencer recruitment.

Features to verify before committing

Ask vendors specifically about:

• True multi-workspace architecture (not just multiple logins)
• Role-based access control (RBAC)
• Brand-level permissions for team members
• Client-specific influencer databases
• Separate payout wallets per client
• White-label reporting
• API access for agency dashboards
• Bulk onboarding and migration tools

For an agency managing several ecommerce brands, impact.com is often the strongest choice if you need robust affiliate infrastructure and governance, while Upfluence offers one of the best balances of influencer discovery, affiliate management, and multi-brand workflows. If your agency is heavily Shopify-focused and prioritizes ease of use over enterprise complexity, GRIN or Social Snowball can be excellent fits.

If you're an agency managing multiple ecommerce brands, the key capabilities to look for are:

• Multi-client workspaces (separate data per brand)
• Granular team permissions (account managers only see assigned brands)
• Client logins with limited approval access
• Separate affiliate programs and creator databases per client
• Consolidated agency billing and reporting

Here are the strongest options:

Best overall for agencies

impact.com

• Industry-leading affiliate platform
• Separate advertiser accounts for each client
• Role-based permissions
• Clients only access their own programs
• Strong Shopify, BigCommerce, WooCommerce, and Magento integrations
• Best if you're running serious affiliate programs at scale.

CreatorIQ

• Better if your focus is influencer relationship management rather than affiliate tracking.
• Supports agency teams with permission controls and brand separation.
• Enterprise pricing.

Influentials
This platform is built with agencies in mind. It offers:

• One login across multiple client workspaces
• Granular team roles
• Client-specific approval workflows
• White-label reporting
• Consolidated or per-client billing www.influentials.com

Best for Shopify agencies

If every client is on Shopify:

• UpPromote is cost-effective and easy to deploy across many stores.
• Social Snowball is excellent for creator-driven affiliate programs and referral marketing.
• Both are much less expensive than enterprise solutions.

If you're managing 10–100 ecommerce brands

A common stack looks like:

• impact.com for enterprise affiliate management
• Social Snowball for Shopify-first DTC brands
• CreatorIQ or GRIN for influencer CRM and campaign management
• Internal agency users restricted by role, while each client sees only their own brand.

If you share approximately:

• how many ecommerce brands you manage,
• whether they're mostly Shopify,
• and your budget range (e.g. under $1k/month, $1–5k/month, or enterprise),

I can narrow it down to the 2–3 platforms that best fit your agency model.

If you're managing influencer affiliate programs for multiple ecommerce brands, the biggest differentiators are:

• Agency workspaces (one client = one workspace/account)
• Granular team permissions (account managers, admins, finance, client viewers)
• Client isolation (clients can't see each other's creators or data)
• Cross-brand reporting
• Affiliate tracking and payouts

Here are the strongest options:

Best overall for agencies: Impact.com

If your agency runs affiliate programs for multiple brands, Impact is one of the strongest platforms because it supports:

• Separate advertiser accounts for each client
• User roles with granular permissions
• Team member access by account
• Dedicated client logins
• Affiliate, influencer, ambassador, and partnership management in one system
• Shopify, BigCommerce, WooCommerce, and custom integrations

It's particularly well suited if you're managing hundreds or thousands of affiliates across brands.

Best for Shopify-focused ecommerce: Upfluence

Upfluence is popular with ecommerce agencies because it combines:

• Influencer CRM
• Affiliate tracking
• Discount code attribution
• Shopify integration
• Brand-specific workspaces
• Team roles for account managers and clients

Many agencies appreciate having influencer discovery, outreach, gifting, and affiliate management in one platform.

Best if creators are the focus: GRIN

GRIN is designed around creator relationships rather than traditional affiliate networks.

Strengths include:

• Brand-specific creator databases
• Affiliate links and codes
• Product seeding
• Team permissions
• Client-specific reporting
• Shopify-native workflows

It's a strong fit for agencies running creator programs for DTC brands.

Enterprise option: CreatorIQ

If your clients are large consumer brands, CreatorIQ offers:

• Multi-brand management
• Sophisticated permission controls
• Approval workflows
• Enterprise reporting
• Global influencer databases

It's powerful but typically comes with enterprise pricing.

Which I'd recommend based on agency size

• 5–20 ecommerce brands: Upfluence or GRIN
• 20–100+ brands: Impact.com
• Enterprise/global brands: CreatorIQ
• Performance-heavy affiliate programs with influencers and publishers: Impact.com

One question that would help narrow it down: are you primarily managing Shopify DTC brands, or are you looking for a platform that supports multiple ecommerce platforms and traditional affiliate publishers as well?

If you're an agency managing multiple ecommerce brands, you generally want a platform with:

• Multi-brand workspaces (each client isolated)
• Role-based team permissions (account managers only see assigned brands)
• Client logins or view-only access
• Affiliate + influencer management in one place
• Consolidated reporting across brands

Here are the strongest options:

Best overall for agencies

Notable features include:

• one login across multiple client brands
• assign team members to specific brands only
• separate client workspaces
• client approval workflows

Best enterprise option

2. impact.com

If you're running large affiliate programs (thousands of partners), impact.com is probably the most mature platform.

Pros:

• enterprise-grade permissions
• business unit segmentation
• multiple advertiser accounts
• influencer + affiliate in one ecosystem
• extensive Shopify, BigCommerce, and ecommerce integrations

It's ideal for agencies with larger clients or complex partner programs.

Best for Shopify ecommerce

3. Upfluence

A strong fit if most of your clients are on Shopify.

Highlights:

• influencer CRM
• affiliate tracking
• discount code generation
• creator discovery
• commission management

Best if creators are the priority

4. GRIN

Popular with DTC brands focused on creator relationships.

It offers:

• creator CRM
• affiliate links and discount codes
• product seeding
• content approvals
• team collaboration

It's more creator-centric than affiliate-network-centric.

If your agency manages 10–50 brands

Your ideal feature set is:

• Separate workspace per client
• Brand-level permissions
• Client-specific reporting
• Shared creator database (optional)
• Affiliate tracking
• Shopify integration
• Approval workflows
• Team assignment by account manager

Among current platforms, Influentials and impact.com align most closely with those requirements, while Upfluence is an excellent choice for Shopify-focused DTC agencies. www.influentials.com

If you can share:

• approximately how many client brands you manage,
• whether they're primarily on Shopify, WooCommerce, or another platform,
• and whether you're looking for affiliate tracking only or a combined creator discovery + outreach + affiliate management solution,

I can narrow the recommendations to the two or three platforms that best fit your agency's workflow.

If you're an agency managing multiple ecommerce brands, the key capabilities to look for are:

• Multi-client workspaces (each brand isolated)
• Granular team permissions (account managers, finance, admins)
• Client logins with limited access
• Affiliate and influencer management in the same platform
• Consolidated reporting across brands

Here are the strongest options:

For agencies specifically, I'd narrow it further:

1. impact.com

Best if each ecommerce client has a mature affiliate program.

Pros:

• Enterprise-grade permission controls
• Separate advertiser accounts
• Cross-account management
• Influencer, affiliate, referral, and ambassador programs in one ecosystem
• Excellent Shopify, BigCommerce, Magento, and custom integrations

Ideal for agencies managing 10–100+ brands.

2. Upfluence

Probably the best balance for ecommerce agencies.

It combines:

• Influencer discovery
• Affiliate tracking
• Discount codes
• Product gifting
• Shopify integrations
• Team roles
• Multi-brand management

Especially strong if clients rely heavily on creator seeding and UGC.

3. GRIN

Great when clients primarily run influencer programs.

Highlights:

• Brand-specific workspaces
• Team permissions
• Creator CRM
• Affiliate links and discount codes
• Ecommerce integrations

Less affiliate-network focused than impact.com.

4. CreatorIQ

Best for larger agencies serving enterprise brands.

Offers:

• Advanced user roles
• Permission hierarchies
• Multiple brands under one organization
• Enterprise reporting
• Large creator database

Typically comes with enterprise pricing.

If agency operations are your biggest concern

Some newer platforms are also building agency-first features like:

• Multi-brand workspace switching
• Granular team roles
• Client-specific approvals
• White-label reporting
• Consolidated billing for multiple clients www.influentials.com

My recommendation by agency size

• 1–10 Shopify brands: Upfluence
• 10–50 ecommerce brands: impact.com
• Large enterprise clients: CreatorIQ
• Influencer-heavy DTC brands: GRIN
• Affiliate-heavy programs with multiple partner types: impact.com

If you can share approximately how many brands you manage (e.g. 10, 30, or 100+) and your clients' average monthly GMV, I can recommend the platform that's likely to fit both your operational needs and budget.
