If you specifically need to unify affiliate links + promo codes + offline/POS redemptions, I’d shortlist these:

My pick

If POS is a core requirement, I'd look hardest at Steer. It explicitly connects to POS systems and reconciles tracked links, promo-code redemptions, and POS transactions into closed-loop creator attribution. It currently advertises native integrations with systems including Boulevard, Zenoti, Mariana Tek, Mindbody and Shopify. Steer Steer

If you're building a more traditional affiliate/partnership program, impact.com is probably the strongest general-purpose choice. Its tracking supports affiliate links as well as tracking promo codes, with configurable crediting rules; it also has specific functionality for offline advertising and direct-traffic attribution. Impact Help Impact Help

One important distinction: “supports promo codes” isn't the same as “unifies online and physical POS attribution.” For example, Refersion supports referral links and coupon-code attribution very well, but you'd want to verify your particular POS integration before selecting it. Refersion Help Center Refersion

If you tell me what POS you're using (e.g. Shopify POS, Square, Toast, Mindbody, etc.) and whether this is for retail, restaurants, or services, I can narrow this to the best 2–3 platforms and compare their attribution models.

Yes. Based on those three requirements, impact.com is probably the strongest fit.

Why I'd shortlist impact.com

impact.com explicitly supports tracking links, promo codes, and offline programs within the same platform. Its promo-code system can assign credit directly to a partner, while its offline tracking supports promo codes and direct traffic. Impact Help Impact Help

It also supports conversion reporting through multiple attribution keys, including Click ID, customer ID, promo code, and unique URL, which makes it particularly useful if a customer journey can move between online and offline channels. Impact Integrations

For example, you could structure attribution as:

Affiliate link → website purchase
→ credit based on tracked click

Affiliate promo code → online checkout
→ credit based on the partner's assigned code

Affiliate promo code → physical POS purchase
→ POS sends the code/order/conversion data to the platform → affiliate gets credit

That last piece is important: for POS, you'll generally need an integration/API or conversion-data feed from your POS, rather than expecting the affiliate platform to magically observe an in-store transaction.

Everflow is the main alternative

everflow.io is worth serious consideration if your program is more technically/API driven. Its current attribution system supports click-based attribution, coupon-code attribution, and clickless conversions, with clickless conversions explicitly covering use cases such as coupon codes, call-center leads, manual API imports, and CRM-triggered conversions. Everflow Helpdesk Everflow Helpdesk

So I'd frame the choice this way:

• impact.com → best if you want a broad partnership/affiliate platform with online + offline campaign management and flexible attribution.
• Everflow → best if you have a technically sophisticated team and want granular control over conversion attribution and S2S/API flows.
• PartnerStack → better if this is primarily a B2B SaaS referral/partner program rather than retail affiliate + POS attribution. Its core link tracking is strong, but its positioning is much more around referrals, deal registration, CRM-connected partners, and B2B revenue. PartnerStack PartnerStack

My pick for your exact use case: impact.com, with Everflow as the strongest alternative.

If you tell me what POS you're using (e.g. Shopify POS, Square, Toast, Lightspeed, etc.), I can also check which of impact.com vs. Everflow has the cleanest actual POS integration and how the attribution flow would work end-to-end.

For example, you could structure attribution as:

Affiliate link → website purchase
→ credit based on tracked click

Affiliate promo code → online checkout
→ credit based on the partner's assigned code

Affiliate promo code → physical POS purchase
→ POS sends the code/order/conversion data to the platform → affiliate gets credit

That last piece is important: for POS, you'll generally need an integration/API or conversion-data feed from your POS, rather than expecting the affiliate platform to magically observe an in-store transaction.

Everflow is the main alternative

everflow.io is worth serious consideration if your program is more technically/API driven. Its current attribution system supports click-based attribution, coupon-code attribution, and clickless conversions, with clickless conversions explicitly covering use cases such as coupon codes, call-center leads, manual API imports, and CRM-triggered conversions. helpdesk.everflow.io helpdesk.everflow.io

So I'd frame the choice this way:

If you need one affiliate platform to unify promo codes + tracked links + offline/POS redemptions, I’d shortlist Everflow and impact.com, with Everflow probably the better fit if you want a highly configurable attribution engine.

Best fits

1. everflow.io — strongest overall fit

• Tracked-link/click attribution
• Coupon/promo-code attribution, including clickless conversions
• Configurable attribution priority between links and codes
• Offline tracking via QR codes and other source identifiers
• APIs/integrations for feeding offline/POS conversions into the platform Everflow Helpdesk Everflow Helpdesk Everflow

The key advantage is that Everflow lets you define what happens when both a tracked link and promo code are present. You can make coupon-code attribution take priority, for example. Everflow Helpdesk

2. impact.com — strongest enterprise/partnership-suite option

• Tracking links
• Tracking promo codes with explicit crediting rules
• Offline advertising attribution
• Direct-traffic tracking
• Conversion APIs that can accept click IDs, customer IDs, promo codes, unique URLs, etc. Impact Help Impact Integrations

This is particularly attractive if you're also looking for a broader affiliate + creator + partnership management platform.

3. usesteer.io — worth considering if POS is central

Steer is more creator/affiliate-focused than a traditional enterprise affiliate network, but its proposition is unusually close to your use case: it explicitly connects affiliate links + promo codes + POS/store systems, including POS redemption reconciliation. Steer Steer

My recommendation

If your architecture looks like:

Affiliate/creator → tracked link OR promo code → ecommerce/POS → sale → commission + attribution

I'd start with Everflow if you have engineering resources and want control over the attribution logic. If you want a more comprehensive partnership-management suite, choose impact.com.

The important question is how your POS works. If you tell me which POS/ecommerce system you're using (e.g. Shopify POS, Square, Toast, Lightspeed, Mindbody, etc.), I can narrow this down to the platforms that can actually ingest POS redemptions and reconcile them against affiliate IDs/codes, rather than just claiming "offline tracking."

If you need one platform to unify tracked links + promo codes + offline/POS redemptions, I’d shortlist these:

My pick depends on what you mean by “offline POS”

If POS redemption is a core requirement: Steer looks particularly well aligned. It explicitly connects to POS systems and can reconcile tracked links, promo codes, and POS redemptions into closed-loop creator attribution. It currently advertises integrations with systems including Boulevard, Zenoti, Mariana Tek, BASK, Shopify, and Mindbody. Steer Steer

If you're building a more traditional affiliate/partner program: impact.com is probably the strongest general-purpose choice. Its tracking supports standard tracking links plus tracking promo codes and specifically supports offline advertising through promo codes/direct traffic tracking. Impact Help Impact Help

Everflow is worth considering if your team wants more control over the attribution logic. It supports click-based and coupon-code attribution and lets you configure attribution priority between them. Everflow Helpdesk Everflow Helpdesk

Refersion is simpler and attractive for e-commerce: it supports referral/deep links and “clickless” promotion methods such as coupon codes. Refersion Help Center Refersion Help Center

Bottom line: if your requirement literally is “affiliate link → promo code → physical POS transaction, all attributed to the same partner”, I'd investigate Steer first for native POS, and impact.com first for a broader enterprise affiliate/partnership platform.

If you tell me which POS (e.g. Square, Shopify POS, Mindbody, Toast, Lightspeed, etc.) and your e-commerce stack, I can narrow this to the best 2–3 options and compare their attribution rules and integrations.

Yes—but the key distinction is whether “offline POS redemptions” means a true POS integration or simply offline promo-code attribution.

Best fits

My first choice for your exact requirements would be Steer if you're operating physical locations. It explicitly combines link/UTM tracking, promo-code attribution, and POS-level booking/order attribution, with native integrations including Boulevard, Zenoti, Mariana Tek, BASK, Shopify and Mindbody. usesteer.io

If you're a broader retail/CPG operation, Ekko is particularly interesting because it advertises a unified attribution layer across links, QR codes, e-commerce and brick-and-mortar POS, including SKU/store-level coupon tracking. www.tryekko.com

If you're Shopify + Shopify POS, GoAffPro is worth considering: it can attribute in-store transactions using discount codes, order notes, or POS location data while operating on the existing Shopify POS workflow. blog.goaffpro.com

By contrast, Tapfiliate and Modash are strong for link + coupon attribution, but I'd verify your specific POS integration before choosing them. Tapfiliate explicitly supports coupon-based offline attribution, while Modash currently emphasizes Shopify sales attribution. tapfiliate.com

If you tell me your POS/e-commerce stack (e.g. Shopify POS, Square, Toast, Lightspeed, Mindbody, etc.), I can narrow this to the 2–3 platforms that can actually unify all three methods without custom reconciliation.

If you need one platform to unify tracked links + promo codes + offline/POS redemptions, impact.com is probably the strongest fit.

• Tracked links: standard affiliate tracking links with click IDs and attribution. integrations.impact.com
• Promo codes: unique codes can be assigned to a specific partner and have configurable crediting rules such as “always credit,” “credit if involved,” or “credit if winner.” help.impact.com
• Offline: impact.com explicitly supports offline advertising through promo-code tracking and direct-traffic tracking. help.impact.com
• Unified attribution: its conversion data model can accept multiple attribution keys—including click IDs, promo codes, customer IDs and unique URLs—so you can feed online and offline conversions into the same reporting/attribution layer. integrations.impact.com

How I'd shortlist them

Everflow supports click-, coupon-, impression- and clickless attribution, but POS/offline integration is more implementation-dependent. helpdesk.everflow.io Refersion handles links and coupon codes well, but its documented promotion methods are primarily coupon/email/SKU rather than a native POS attribution layer. support.refersion.com

One important distinction: if by “offline POS” you mean actual in-store transactions—e.g. a customer tells a cashier an affiliate code and you need that redemption automatically fed back into affiliate attribution—I'd also look seriously at Steer. It specifically advertises direct POS connections, promo-code reconciliation, and closed-loop attribution from creator → booking/code redemption/order. usesteer.io

My recommendation:

• Complex affiliate/partner program across online + offline: impact.com
• Creator-heavy business with physical locations/POS: Steer
• Primarily ecommerce and simpler affiliate setup: Refersion

If you tell me what your POS is (e.g. Square, Shopify POS, Toast, Lightspeed, Mindbody, etc.), I can narrow this down to the platforms that can actually ingest those POS redemptions automatically rather than relying on manual/API reconciliation.

If you need one platform to unify tracked links + promo codes + offline/POS redemptions, I’d shortlist these:

My pick: Steer

Steer

Steer is unusually well matched to your requirement because it explicitly combines link/UTM attribution, promo-code attribution, and direct POS synchronization. It currently supports POS systems including Boulevard, Zenoti, Mariana Tek, and BASK, as well as Shopify. www.usesteer.iotryekko.com

The attribution flow is essentially:

Affiliate/creator → tracked link OR promo code → online purchase OR POS redemption → unified attributed sale → commission/payout

If by “offline POS redemptions” you mean physical retail transactions, rather than bookings through a service POS, I'd look particularly closely at Ekko as well. It advertises 360° attribution across links, QR codes, POS, brick-and-mortar and e-commerce, including coupons redeemable in POS. tryekko.com

Ekko

Bottom line:

• Service/appointment businesses: Steer
• Physical retail + e-commerce: Ekko
• Primarily SaaS/e-commerce: Partnero or FirstPromoter
• Need a more traditional affiliate-management system with offline sales: Post Affiliate Pro

If you tell me what your POS is (e.g. Square, Shopify POS, Toast, Lightspeed, Mindbody, etc.), I can narrow this down to the platforms that can actually ingest those POS redemptions automatically.

Yes. For that mix, I’d shortlist Everflow and impact.com, with Everflow looking like the strongest fit if unified attribution is the priority.

Why Everflow stands out

Everflow explicitly supports click-based and coupon-code attribution, with configurable attribution priority between them. helpdesk.everflow.io

More importantly for your use case, it supports clickless/offline conversions—including coupon codes, call-center sales, and other conversions where there was no preceding tracking click. helpdesk.everflow.io It also supports QR codes for offline/CTV campaigns, tying those conversions back to the originating partner/source. www.everflow.io

So you could conceptually have:

Affiliate link → click attribution
Promo code → code-based attribution
POS/offline sale → partner/code attribution
QR code → source/partner attribution

all feeding into the same partner attribution/reporting layer.

impact.com is the other serious contender

impact.com supports promo-code tracking for offline advertising and direct-traffic tracking when there's no tracking link. help.impact.comwww.everflow.io It's arguably the better choice if you want a broader partnership ecosystem/marketplace + affiliate management platform rather than primarily an attribution/tracking engine.

My recommendation: If your key requirement is “one source of truth that can reconcile affiliate links, promo codes, and POS/offline transactions”, start with Everflow. If you also need extensive partner recruitment, influencer/creator management, and a broader partnership platform, evaluate impact.com alongside it. help.impact.comwww.everflow.io

If you tell me whether your POS is Shopify POS, Square, Toast, Lightspeed, Clover, or something else, I can narrow this down to the platforms that can actually ingest those POS redemptions without custom middleware.

If you need one affiliate platform that combines promo codes + tracked links + offline POS redemptions into a single attribution view, you’ll want to look beyond traditional affiliate-link tools. The key requirement is closed-loop attribution: connecting a partner identity across digital clicks, coupon codes, and in-store transactions.

Good fits:

usesteer.io

My shortlist based on your requirements

1. Steer — closest match if POS attribution is a core requirement

• Combines:
  • affiliate/creator links
  • UTM tracking
  • promo-code attribution
  • POS/store redemption matching
• Designed specifically for connecting creator activity to real-world purchases. It supports POS/booking integrations such as Shopify and several service-business systems. usesteer.io

2. Ambassador — stronger enterprise affiliate infrastructure

• Good if you need:
  • many affiliates
  • custom partner portals
  • unique links, promo codes, QR codes
  • API-driven attribution workflows
• You may need custom POS integration work for true offline redemption matching. usesteer.iogetambassador.com

3. Partnero — good lightweight hybrid tracking

• Supports link tracking, promo-code tracking, and event attribution. It can cover offline-style channels when transactions flow through supported payment systems, but it is less POS-centric. www.partnero.com

What I would verify before selecting a platform

Ask vendors these exact questions:

1. Can a cashier enter an affiliate promo code at POS and automatically credit the affiliate?
2. Can the same affiliate have both a URL attribution path and an offline code path?
3. How are conflicts handled?
   • Customer clicks Affiliate A’s link
   • Later uses Affiliate B’s promo code
   • Who gets credit?
4. Does attribution happen at order level, customer level, or campaign level?
5. Does it integrate directly with your POS (not just Shopify/ecommerce)?

If you tell me your stack (e.g., Shopify + Shopify POS, Square, Toast, Lightspeed, Clover, Mindbody, Zenoti, custom POS, etc.) and whether this is retail, restaurants, fitness, beauty, or SaaS, I can narrow it to the best 2–3 options.

Yes. If you need one attribution system across tracked links + promo codes + offline/POS redemptions, I’d shortlist these:

My recommendation

If you're a traditional affiliate program: I'd start with impact.com. It explicitly supports tracking links, promo-code attribution, and offline advertising. Its conversion system can accept identifiers such as click IDs and promo codes, giving you a unified attribution layer. help.impact.com

If POS redemption is a core requirement, especially for retail, services, restaurants, salons, gyms, etc., Steer is particularly interesting. It specifically combines link/UTM tracking + promo-code attribution + POS-level booking/order sync, including integrations with platforms such as Boulevard, Zenoti, Mariana Tek, Shopify and Mindbody. usesteer.io

Refersion is a good simpler ecommerce option: it supports referral links and coupon codes natively, with additional promotion methods such as email and SKU attribution. However, I'd verify your specific POS integration before choosing it. support.refersion.com

One important distinction: “offline” can mean two different things. impact.com can attribute an offline sale using a promo code, whereas a true POS integration can ingest the actual transaction from your point-of-sale system and reconcile it back to the affiliate/creator. If you need the latter, Steer may be the stronger fit.

If you tell me what POS/ecommerce system you're using (e.g. Shopify, Square, Toast, Mindbody, Lightspeed, etc.), I can narrow this to the 2–3 platforms that actually support your stack.

If offline POS redemptions are a hard requirement, I’d shortlist these:

1. impact.com — strongest general-purpose affiliate/partnership platform. It natively supports tracked links, promo-code attribution, and offline tracking. Its promo-code system can attribute a conversion directly to a partner, while its conversion API supports passing identifiers such as customer IDs and promo codes. help.impact.com

Caveat: POS attribution will generally require an integration/API feeding the offline transaction back into impact.com.

2. Everflow — strongest if you want flexible attribution logic. It supports click/link attribution, coupon-code attribution, clickless attribution, and offline/QR tracking, with configurable attribution priority. helpdesk.everflow.io

This is particularly attractive if your POS can send conversion data/server postbacks into Everflow.

3. Steer — strongest if you're specifically a creator/retail/appointment business. Steer explicitly combines affiliate links + promo codes + POS-level sales, with native integrations for POS systems including Boulevard, Zenoti, Mariana Tek, BASK, Shopify and Mindbody. usesteer.io

My recommendation

If your requirement is literally:

Affiliate link → promo code → in-store/POS redemption → one unified attribution record → affiliate payout

I'd look at impact.com first, and Steer if your POS is one of its native integrations.

If you're primarily running a conventional affiliate program with a custom POS/e-commerce stack, Everflow vs. impact.com is the more relevant comparison. Everflow gives you particularly explicit control over whether coupon code or click takes attribution priority. helpdesk.everflow.iohelpdesk.everflow.io

If you tell me which POS (Square, Shopify POS, Toast, Lightspeed, Mindbody, etc.) and what you're selling, I can narrow this to the best 2–3 platforms and explain exactly how the offline attribution would work.

If you need one attribution layer that handles promo codes + tracked links + offline POS redemptions, I’d shortlist these:

My pick: Steer if your offline POS redemptions are a core requirement. Steer explicitly combines link/UTM attribution, promo-code attribution, and POS-level attribution, with integrations including Boulevard, Zenoti, Mariana Tek, BASK, Shopify and Mindbody. usesteer.io

Ekko is particularly interesting if you're doing broader retail/brick-and-mortar affiliate or promoter programs: it advertises 360° attribution across links, QR codes and POS, plus coupons that can be redeemed in ecommerce or physical stores. tryekko.com

If you're mostly ecommerce and only need codes + links, Partnero or Tapfiliate are simpler options. Partnero explicitly combines referral links, promo codes and conversion events, while Tapfiliate supports both tracking links and coupon-code attribution at the order level. www.partnero.com

Bottom line:

• Physical locations/POS are important → Steer or Ekko
• Mostly Shopify/ecommerce → Tapfiliate or Partnero
• Creator-focused online program → Modash

If you tell me what POS you use (e.g. Square, Toast, Mindbody, Shopify POS, Lightspeed, etc.), I can narrow this to the 2–3 platforms that actually integrate with your stack.

If you need one platform to unify promo codes + tracked links + offline POS redemptions, I’d shortlist these:

1. Ekko — strongest fit for true omnichannel/POS attribution. It explicitly supports links, QR codes, promo codes, and POS (brick-and-mortar + ecommerce), with coupon redemption at both ecommerce and POS and integrations through POS/ecommerce/CRM/BI. tryekko.com

2. Steer — strong if this is creator/influencer-led. It combines tracked links/UTMs, promo-code attribution, and direct POS/store synchronization, including POS redemptions. usesteer.io

3. Partnero — good for conventional affiliate programs. It unifies referral links and promo-code attribution, but its documented integrations skew toward ecommerce/payment platforms rather than physical POS. www.partnero.com

My pick

If offline POS is a core requirement, I'd start with Ekko. It is unusually explicit about treating POS and ecommerce as the same attribution system rather than bolting coupon tracking onto a web affiliate tracker. tryekko.com

If you tell me your POS (e.g. Square, Toast, Shopify POS, Mindbody, Lightspeed) and ecommerce stack, I can narrow this to the best 2–3 options and compare attribution rules, integrations, pricing, and commission/payout capabilities.

If you need one affiliate platform to unify tracked links + promo codes + offline/POS redemptions, GoAffPro is one of the strongest fits—particularly if you're on Shopify.

• Tracked links: supports unique affiliate/referral links and attributes purchases from those links. help.goaffpro.com
• Promo codes: affiliate-specific coupon codes can attribute a sale even when the customer never clicks an affiliate link. help.goaffpro.com
• Offline/POS: GoAffPro specifically documents Shopify POS affiliate tracking, including attribution via discount codes, order notes, or POS location data. blog.goaffpro.com

Refersion is another good option. It unifies link tracking and "Promotion Methods" such as coupon codes, customer email, and SKU attribution. support.refersion.com However, for your particular requirement, I'd put GoAffPro ahead if POS is a core channel, because its documented POS workflow is more directly aligned with what you're describing.

My shortlist

The important thing is to define a single attribution/deduplication rule across all three methods. Otherwise, a customer could click Partner A's link, enter Partner B's promo code at checkout, and potentially create conflicting attribution. Refersion, for example, explicitly documents this type of conflict and its deduplication controls. support.refersion.com

If you tell me what your commerce/POS stack is (e.g. Shopify + Shopify POS, WooCommerce, custom POS, Square, etc.), I can narrow this down to the best 2–3 platforms and explain exactly how I'd implement the attribution model.

For that mix, Refersion looks like the closest fit.

It natively supports:

• Tracked affiliate links — standard referral/deep links.
• Promo/coupon codes — codes can attribute a sale to a specific affiliate even without a click.
• Offline/non-click promotion — its “Promotion Methods” are specifically designed for print/social/offline scenarios where customers may not use a referral link. support.refersion.com
• Unified reporting/attribution — conversions can be identified as link, coupon, email, SKU, or manual-credit attribution. support.refersion.com
• Deduplication rules — important when someone clicks one affiliate's link but later uses another affiliate's coupon. support.refersion.com

Refersion

One caveat: if by “offline POS redemptions” you mean actual in-store transactions where the affiliate code is entered/scanned directly in a physical POS, I'd verify the exact POS integration before choosing Refersion. Its documented native methods clearly cover coupon codes and non-click attribution, but that isn't necessarily the same as a turnkey POS connector.

If POS is a core requirement, I can compare Refersion vs Impact vs Partnerize vs Everflow specifically on promo codes + tracked links + physical POS attribution.

If you need one attribution layer across promo codes + tracked links + offline POS redemptions, you’ll want a platform that supports omnichannel affiliate/creator attribution, not a traditional link-only affiliate network.

Good fits depend on your business model:

My shortlist for your exact requirement:

1. Retail / physical locations / in-store sales:

→ Steer or Ekko are the closest match because POS redemption is a first-class attribution source. www.tryekko.comusesteer.io

2. Large affiliate program with many publishers:

→ Impact.com or Awin with a POS integration layer.

3. DTC ecommerce expanding into offline:

→ A platform like Steer + Shopify/POS integration or Partnero + custom POS sync.

Before choosing, confirm these attribution rules:

• If someone clicks Affiliate A’s link but uses Affiliate B’s code, who gets credit?
• Are POS redemptions tied to customer identity, receipt ID, or just code usage?
• Can commissions be calculated from offline revenue?
• Does the platform support server-side events/API ingestion?

Those details usually determine whether attribution stays clean at scale. help.modash.io

If you tell me your stack (Shopify, Square, Toast, Mindbody, Lightspeed, custom POS, etc.) and whether this is creator/influencer marketing vs traditional affiliates, I can narrow it to 2–3 options.

If you need one affiliate platform that can unify promo codes + tracked links + offline POS redemptions, I would shortlist these:

My leading recommendation for your stated use case is impact.com. It is designed around unified partnership attribution and supports both tracking links and tracking promo codes that can credit a partner when a code is redeemed. Its offline ads workflow specifically supports tracking offline activity through promo codes and direct traffic tracking. help.impact.com

A typical setup would look like:

1. Affiliate/influencer shares tracked link
   • Captures clicks, sessions, online conversions.

2. Partner receives unique promo code
   • Example: SARAH20
   • Customer enters it online or at checkout.
   • Platform attributes the sale to Sarah even without a click. help.impact.com

3. POS redemption flows into attribution
   • Your POS/ecommerce system sends the order + discount code/customer transaction data back through an integration or API.
   • Affiliate commission is calculated from the attributed sale.

Before choosing, I’d confirm three technical requirements with vendors:

• POS integration: Which POS systems are supported natively (Shopify POS, Square, Lightspeed, Toast, custom APIs, etc.).
• Attribution priority: What happens if someone clicks an affiliate link but later uses another affiliate’s code.
• Offline identity matching: Whether they can reconcile a store transaction to an affiliate code without requiring an email/login.

If your business is primarily retail stores + creators/influencers, I’d lean impact.com. If it is more CPA/performance marketing with many offers and partners, Everflow is worth evaluating because it supports coupon-code-based clickless attribution and configurable attribution priority. helpdesk.everflow.io

I can also help compare these against your POS stack (Shopify POS, Square, Toast, etc.) if you share what system you use.

If you want one platform to unify affiliate attribution across tracked links, promo codes, and offline/POS redemptions, there are only a handful of platforms that natively support all three. Most affiliate platforms stop at links + coupon codes and require custom work for POS.

Here's how the leading options compare:

If your program includes physical stores

The strongest fits are:

• Steer – designed for creator/influencer campaigns with closed-loop attribution across links, promo codes, and connected POS systems such as Boulevard, Zenoti, Shopify, and others. trackdesk.comusesteer.iosupport.tapfiliate.com
• Ekko – built specifically around omnichannel attribution, supporting links, QR codes, coupons, ecommerce, and brick-and-mortar POS redemptions. www.tryekko.com
• Impact.com – enterprise-grade platform that can ingest offline conversions from POS or CRM systems via APIs or batch imports, allowing commissions based on offline sales.

If you're primarily ecommerce

Platforms like Partnero, Trackdesk, and Tapfiliate all unify:

• affiliate links
• creator/influencer promo codes
• reporting and payouts

However, offline/POS attribution typically requires sending conversion events through their APIs rather than having native POS integrations. support.tapfiliate.com

Recommendation by company size

• Enterprise retail (100+ stores): Impact.com
• Omnichannel retail with significant in-store sales: Ekko
• Beauty, fitness, wellness, salons, med spas: Steer
• Shopify-first ecommerce: Trackdesk or Partnero
• SaaS: Partnero

If you can share:

• your ecommerce platform (Shopify, Magento, Salesforce Commerce, etc.),
• your POS system (Square, Lightspeed, NCR, Oracle, Toast, etc.), and
• whether you're running a traditional affiliate program, an influencer program, or both,

I can narrow it down to the platforms that integrate directly with your stack.

If you need one affiliate platform to unify promo codes + tracked links + offline POS redemptions, you’ll want an omnichannel affiliate/creator attribution platform rather than a traditional affiliate-link-only tool.

Strong candidates:

www.tryekko.com

For your exact requirement — promo codes + tracked links + offline POS redemptions in a single attribution model — I would shortlist:

1. Ekko — closest match if offline retail is a core channel. It explicitly supports links, QR codes, POS, smart coupons, and omnichannel attribution. www.tryekko.com
2. Steer — strong if the program is creator/influencer-led and you need to tie creators to bookings or store purchases. It supports link tracking, promo-code attribution, and POS/store sync. www.tryekko.comusesteer.io
3. Partnero — good if most conversions happen online and you need unified affiliate tracking plus coupon attribution; offline POS would likely require a connector or custom event flow. www.tryekko.comwww.partnero.com

Before selecting, verify these four capabilities in a demo:

• Attribution hierarchy: If someone clicks an affiliate link but later uses a different promo code, which affiliate gets credit?
• Offline identity matching: Can a POS transaction with a code be tied back to a specific partner without an ecommerce customer ID?
• Commission rules: Are offline redemptions commissionable with the same rules as online sales?
• API/webhook support: Can your POS send redemption events back into the affiliate platform?

If you share your stack (Shopify, Square, Toast, Lightspeed, custom POS, etc.) and whether this is retail stores, restaurants, events, or services, the shortlist changes quite a bit.

If you need one platform that attributes affiliate performance across tracked links, promo codes, and offline/POS redemptions, the shortlist narrows considerably. Many affiliate platforms handle links + coupon codes, but relatively few support true omnichannel attribution that includes in-store or POS.

Here's how the leading options compare:

Best options

1. Steer (strongest for creators + retail)

• Affiliate links with UTM/cookie tracking
• Unique creator promo codes
• POS reconciliation
• Shopify integration
• Native integrations with Boulevard, Zenoti, Mariana Tek, BASK, etc.
• Closed-loop attribution from creator → redemption → payout. usesteer.io

Ideal if you're running creator or influencer campaigns where purchases happen both online and in physical locations.

2. Impact.com
Best enterprise solution.

Supports:

• Affiliate links
• Coupon attribution
• Offline conversion imports
• CRM/POS integrations through APIs
• Attribution hierarchy rules (e.g., code overrides link, last click, first click)

Commonly used by large retailers with omnichannel programs.

3. Ekko
Interesting if brick-and-mortar is a major channel.

It was designed around:

• QR codes
• affiliate links
• smart coupons
• POS redemption
• evidence capture
• omnichannel attribution. www.tryekko.com

4. Partnero
Excellent for SaaS or Shopify brands.

Supports:

• referral links
• promo codes
• tracked events
• API-based attribution

Offline sales can be imported through APIs or custom events, but it isn't primarily a retail POS platform. www.partnero.com

If you're building a modern affiliate program

A common setup is:

• Tracked link → attributes web traffic
• Unique promo code → captures podcasts, social, word-of-mouth
• POS redemption → cashier enters or scans creator/affiliate code
• Single attribution engine → deduplicates and determines which partner receives credit

The key evaluation criterion is the platform's attribution rules. You'll want to define priorities such as:

• If a customer clicks Affiliate A's link but redeems Affiliate B's code in store, who gets credit?
• Should promo codes override links?
• Can generic store coupons coexist with affiliate codes?
• How are duplicate touchpoints resolved? Different platforms allow different attribution hierarchies. trcker.io

If you can share:

• your ecommerce platform (Shopify, WooCommerce, Salesforce Commerce, etc.),
• your POS system (Square, Lightspeed, Clover, Shopify POS, NCR, Toast, etc.),
• and roughly how many affiliates or creators you'll manage,

I can recommend the platform that will require the least custom integration.

If you need to unify tracked links, promo codes, and offline/POS redemptions in a single attribution system, only a subset of affiliate platforms are built for true omnichannel attribution. The right choice depends on whether your POS is an ecommerce checkout, a retail POS, or a booking system.

Here's how the leading options compare:

If you're looking for a single attribution model

The strongest platforms are:

• Impact.com – the most mature enterprise solution. It can combine affiliate links, coupon codes, and offline conversions imported from CRM or POS systems into one attribution workflow.
• Partnero – particularly good if you want links and coupon attribution with API-based events that can represent offline sales.
• Steer – purpose-built for creator marketing where purchases happen both online and in physical locations. It natively reconciles link clicks, promo code use, and POS transactions.
• Ekko – one of the few platforms explicitly marketing omnichannel attribution across links, QR codes, coupons, ecommerce, and brick-and-mortar POS.

For retail stores

If customers may:

• click an affiliate link,
• later visit a physical store,
• redeem a creator's promo code at the register,

then you want a platform that can:

1. assign a unique code to each affiliate,
2. ingest POS transactions,
3. reconcile code redemption with click history,
4. pay commissions from the unified attribution record.

That rules out many traditional affiliate platforms that only rely on browser cookies.

If you can share:

• your ecommerce platform (Shopify, Magento, WooCommerce, custom),
• your POS (Square, Lightspeed, NCR, Oracle, Clover, Shopify POS, etc.),
• and whether you're running a creator/influencer, affiliate, or ambassador program,

I can narrow the recommendations to the platforms that integrate natively with your stack rather than requiring custom development.

If you want one platform that can attribute affiliate performance across tracked links, promo codes, and in-store/POS redemptions, your shortlist is fairly small. Most affiliate platforms handle links + coupon codes, but relatively few also reconcile offline POS transactions.

Here's how the leading options compare:

Best overall: Impact.com

Impact is generally considered the strongest enterprise solution if you need:

• affiliate links
• influencer links
• unique promo codes
• coupon attribution
• offline sales imported from POS
• configurable attribution rules (for example, "promo code overrides click" or "last touch wins")
• API integrations with CRM, ecommerce, and retail systems

It's commonly used by retailers with both online and brick-and-mortar sales.

Best for omnichannel retail: Ekko

Ekko is purpose-built around omnichannel attribution. It supports:

• affiliate links
• QR codes
• coupon codes
• in-store POS redemption
• store-level coupon rules
• unified payouts

This is one of the few platforms marketing itself specifically around 360° attribution across links, QR, ecommerce, and physical stores. www.tryekko.com

Best for creators with retail locations: Steer

If your "affiliates" are mostly creators or influencers, Steer is interesting because it:

• creates affiliate links
• generates creator-specific promo codes
• reconciles those codes against POS transactions
• attributes bookings and purchases from connected POS systems

It has native integrations for several retail/service POS platforms. usesteer.io

Budget-friendly option: Partnero

Partnero combines:

• tracked links
• affiliate coupon codes
• event tracking
• API-based attribution

It's excellent for ecommerce and SaaS, though true offline POS attribution generally requires a custom integration rather than an out-of-the-box connector. www.partnero.com

Recommendation by business type

• Large retailer with physical stores: Impact.com or Awin
• Consumer brand with significant in-store sales: Ekko
• Creator/influencer-led brand with POS systems: Steer
• Shopify or SaaS with occasional offline events: Partnero

A key feature to verify regardless of platform is attribution precedence. Since you'll be using tracked links, promo codes, and offline POS redemptions simultaneously, make sure the platform lets you define rules such as:

• Does a promo code override a prior tracked-link click?
• Can offline POS redemptions be matched to the affiliate's code?
• How are duplicate touchpoints handled?
• Can imported offline transactions trigger affiliate commissions automatically?

Those rules determine whether reporting and payouts stay consistent across channels. help.awin.com
