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

• impact.com — Strong general-purpose option. It supports tracked affiliate links, promo-code attribution, and offline advertising through promo codes/direct-traffic tracking. Impact Help Impact Help
• everflow.io — Particularly strong if you have a technical/data-heavy setup. It supports click/link attribution, coupon-code attribution, QR codes for offline partners, APIs, and configurable attribution priority. Everflow Everflow Helpdesk
• refersion.com — Good for ecommerce. It natively supports referral links and coupon codes, but POS attribution generally requires an integration/custom data flow, so I'd verify your specific POS before choosing it. Refersion Help Center Refersion Help Center
• usesteer.io — Worth considering if this is primarily creator/influencer + physical-location commerce. It explicitly combines link/UTM, promo-code, and POS attribution, with native integrations including Shopify, Boulevard, Zenoti, Mariana Tek, BASK, and Mindbody. Steer Steer

The key distinction

If by “offline POS redemptions” you mean:

Affiliate posts link → customer visits online OR customer walks into a store → gives cashier affiliate code → POS records redemption → affiliate gets commission

then I would focus on impact.com, Everflow, or a POS-native platform like Steer, rather than choosing a conventional affiliate platform based solely on link tracking.

For a more technical implementation, Everflow is especially interesting because you can configure whether coupon code or click data takes attribution priority, rather than treating them as completely separate channels. Everflow Helpdesk Everflow Helpdesk

If you tell me which POS (e.g. Shopify POS, Square, Toast, Mindbody, Lightspeed, Clover) and whether this is ecommerce, retail, restaurants, or services, I can narrow it down to the platforms that can actually ingest the POS redemption and reconcile commissions automatically.

If you need one affiliate platform that can unify promo codes + tracked links + offline POS redemptions, you’ll want something beyond a traditional link-only affiliate tracker. The key capability is multi-touch / closed-loop attribution: the platform should ingest link clicks, code redemptions, and POS transactions into the same partner record. Steer Steer

Some platforms to evaluate:

Partnero Refersion Help Center Tapfiliate Help Center### If offline POS is a core requirement

I would shortlist platforms that explicitly support POS-level attribution, not just coupon codes. For example, Steer positions itself around connecting creator activity to bookings/orders and reconciling promo codes against POS redemptions. Steer Steer

Questions to ask vendors before choosing

1. Can a single affiliate/creator ID own all attribution paths?

• Link click → online purchase
• Promo code → ecommerce checkout
• Promo code → in-store POS transaction
• QR code → store visit
• How do they resolve conflicts?

Example:

• Customer clicks Creator A’s link
• Uses Creator B’s promo code
• Buys in-store two weeks later

Ask which partner gets credit and whether rules are configurable. Refersion Help Center

3. Do they integrate directly with your POS?

Common POS ecosystems vary widely; a platform that works well with Shopify POS may not work with restaurant, salon, or specialty retail systems.

If you share your POS system (e.g., Shopify POS, Square, Toast, Mindbody, Lightspeed, Clover, custom) and whether this is creator/influencer affiliate, employee referral, or traditional affiliate marketing, I can narrow the shortlist.

I would shortlist platforms that explicitly support POS-level attribution, not just coupon codes. For example, Steer positions itself around connecting creator activity to bookings/orders and reconciling promo codes against POS redemptions.

Yes. For your mix of promo codes + tracked links + offline POS redemptions, I’d shortlist impact.com and Everflow, with impact.com probably the strongest all-around fit.

Best fits

• impact.com — Best overall

• Tracked affiliate links
• Promo-code attribution, including clickless/offline use
• Direct/offline traffic tracking
• Attribution rules and credit policies
• Its conversion data model explicitly supports both click IDs and promo codes. Impact Help Impact Help Impact Integrations
• Caveat: its native POS capabilities depend heavily on your POS/e-commerce integration; you may need an API/integration to feed offline transactions.
• Everflow — Best for sophisticated attribution

• Tracking links
• Coupon-code attribution
• Offline QR/tracking codes
• Configurable attribution priority, so you can decide whether a coupon/code should override a tracked click
• Strong API/postback capabilities for feeding POS transactions into the platform. Everflow Everflow Helpdesk Everflow Helpdesk
• I'd favor this if your POS data needs to be integrated programmatically.
• Partnero — Best lightweight option

• Combines referral links, promo codes, and tracked events.
• It specifically says coupon redemptions can be attributed online or in-store and supports API/server-side events. Partnero Partnero
• Better suited to a simpler affiliate/creator program than a complex enterprise attribution stack.

My recommendation

If your requirement is literally:

Affiliate → tracked link → online purchase
Affiliate → promo code → online purchase
Affiliate → promo code → POS purchase
Affiliate → QR/direct link → offline/online purchase

I'd evaluate impact.com first and Everflow second.

The important question isn't just whether a platform tracks all three—it is whether it can resolve them into one attribution record and apply deterministic precedence rules when multiple signals exist. Everflow, for example, explicitly lets you configure click-vs-coupon attribution priority. Everflow Helpdesk Everflow Helpdesk

If you tell me which POS you use (e.g. Square, Shopify POS, Toast, Lightspeed, Mindbody, Clover), I can narrow this down to the platforms with the best native/API integration for your exact setup.

Yes. For your specific mix—promo codes + tracked links + offline POS redemptions—I’d shortlist impact.com and Everflow, with a notable third option depending on your POS stack.

Best fits

1. impact.com — strongest overall fit

• Tracked affiliate links
• Promo-code attribution, including codes used in offline campaigns
• Direct/no-link tracking
• APIs for sending conversion data from external systems
• Its promo-code system explicitly supports offline advertising and attributes code usage to the assigned partner. Impact Help Impact

I'd choose this if you want a broad partnership platform that can eventually handle affiliates, creators, referral partners, and other partnership types.

2. Everflow — strongest for attribution flexibility

• Standard tracking links/click IDs
• Coupon-code attribution
• QR codes for offline partners
• Clickless attribution
• Configurable attribution priority, so you can decide whether a promo code or tracked click gets precedence. Everflow Everflow Helpdesk

This is particularly attractive if your POS can send conversions into Everflow via API/postback and you want sophisticated control over attribution logic.

3. Partnero — worth considering for simpler creator/affiliate programs

• Standard affiliate links
• Branded/direct links
• Promo codes
• Claims to attribute coupon redemptions both online and in-store. Partnero Partnero

I'd consider it if your program is more creator/influencer-oriented and you don't need the enterprise-level complexity of impact.com or Everflow.

The key distinction

If by "offline POS redemptions" you mean:

Customer walks into a physical store → tells cashier an affiliate/creator promo code → POS records redemption → affiliate gets commission

then I would not choose a platform based solely on its having coupon-code tracking. The important question is whether it can ingest the POS transaction reliably and reconcile the promo code/order back to the affiliate.

For that use case, my ranking would be:

My recommendation: start with impact.com and Everflow. If you tell me which POS you use (e.g. Shopify POS, Square, Toast, Lightspeed, Mindbody, etc.), I can narrow it down to the platform that can actually unify the three attribution paths without building a lot of custom middleware. Impact Help Everflow

If you need one affiliate platform that combines promo codes + tracked links + offline POS redemptions into a single attribution system, you’ll want a platform with multi-touch / closed-loop attribution, not a traditional link-only affiliate tool.

Strong candidates:

My shortlist based on your exact requirements

If “offline POS redemptions” is a core requirement:

• Start with Steer. It is specifically built around connecting creator/affiliate attribution to actual bookings, purchases, and POS systems rather than stopping at clicks. It supports promo-code reconciliation and POS integrations such as Shopify and certain booking/POS systems. Steer

If you are mainly ecommerce:

• Look at Partnero or Tapfiliate. They are strong at combining affiliate links and coupon codes, with integrations into commerce platforms. Partnero Tapfiliate Help Center

If you are enterprise and need partner governance:

• Ambassador is worth evaluating for larger partner ecosystems with multiple attribution assets. Ambassador

Before choosing, verify these four things in a demo:

1. Can a cashier enter an affiliate/creator code at POS and automatically credit the partner?
2. Can the same customer journey combine link click → in-store purchase → commission payout?
3. What is the attribution priority if both a tracked link and promo code exist? (Many systems let the code override the link.) help.modash.io
4. Does it integrate directly with your POS, or will you need a custom API/webhook?

If you share your POS system (e.g., Shopify POS, Square, Toast, Mindbody, Lightspeed, custom POS) and whether this is retail, restaurants, services, or ecommerce, I can narrow it to the best 2–3 options.

If you need one attribution layer that can unify tracked links + promo codes + offline/POS redemptions, I’d shortlist Everflow first.

• Everflow — strongest fit for a broad affiliate/performance program. It supports click/link attribution, coupon-code attribution, QR codes for offline partners, and API/event-based conversion tracking. Its attribution-priority system can determine whether a conversion should be credited via a click, coupon code, or fallback method. Everflow Helpdesk Everflow Everflow Helpdesk
• Steer — potentially better if you are specifically a consumer/retail/service brand using a physical POS. It explicitly connects creator links, promo codes, and POS transactions, including integrations with systems such as Boulevard, Zenoti, Mariana Tek, BASK, and Shopify. Steer Steer
• Partnero — good lighter-weight option for links + promo codes + online/offline code redemptions, with API support for custom conversion events. Partnero Partnero
• Ambassador — supports unique affiliate links, promo codes, QR codes, and cookie/cookieless tracking, making it another candidate if your offline use case is primarily QR/code based. Ambassador

My pick

If “offline POS redemption” means an actual retail POS transaction that needs to flow back into affiliate attribution, I’d evaluate Everflow and Steer first.

The key distinction is:

Everflow:
affiliate → link / promo code / QR → conversion event → attribution → commission

Steer:
creator → link / promo code → POS transaction → closed-loop attribution → payout

If you tell me what POS you use (e.g. Shopify POS, Square, Toast, Lightspeed, Mindbody, Boulevard, etc.) and whether this is primarily affiliate, influencer/creator, or retail partner marketing, I can narrow it down to the best 2–3 platforms and compare POS integration, attribution rules, commission handling, and pricing.

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

1. usesteer.io — strongest fit if POS is central. It explicitly combines link/UTM tracking, promo-code attribution, and native POS/store integrations, including Boulevard, Zenoti, Mariana Tek, BASK, and Shopify. Steer Steer
2. partnero.com — strong general-purpose option. It supports tracked links, promo codes, QR/direct links, and offline/event-driven conversions, with API/webhook support for custom POS workflows. Partnero Partnero
3. myap.com — worth considering for enterprise programs. It supports direct links, promo-code/offline attribution, server-to-server tracking, and configurable attribution models. MYAP MYAP
4. tapfiliate.com — good for ecommerce. It unifies affiliate links and coupon codes, but I'd verify the specific POS integration/API workflow before choosing it for substantial offline sales. Tapfiliate Help Center Tapfiliate

My pick: If by “offline POS redemptions” you mean customers literally redeeming an affiliate/creator code at a physical location, Steer looks closest to your exact requirement because POS attribution is a core part of the product rather than a workaround. Steer

If you tell me what POS you use (e.g. Square, Toast, Shopify POS, Mindbody, Zenoti, Boulevard, etc.), I can narrow this down to the best 2–3 options and compare their attribution models, integrations, and pricing.

If you need one affiliate platform that unifies promo codes + tracked links + offline POS redemptions, you’re looking for a platform with multi-touch partner attribution (not just traditional cookie/link tracking). The strongest fits depend on how important native POS integration is.

My shortlist based on your requirements

1. If POS redemptions are a core channel → Steer is the closest match.
It is specifically built around creator attribution across:

• tracked links/UTMs,
• promo codes,
• bookings/orders,
• POS/store systems. Steer

2. If you mainly need affiliate infrastructure + can connect POS through APIs → Partnero or FirstPromoter.
They unify:

• affiliate links,
• coupon/promo attribution,
• conversion events,
• commission tracking. Partnero FirstPromoter

3. If you are ecommerce-first → Tapfiliate is worth considering.
It supports coupon-based affiliate attribution, which helps capture sales where customers never click an affiliate link. Tapfiliate Help Center

For a true offline + online unified attribution model, I would evaluate platforms against this flow:

Affiliate/creator → tracked link OR promo code OR QR code → customer purchase online or POS → transaction matched back to affiliate → commission calculated automatically

Before choosing, I’d verify:

1. Which POS systems are supported natively.
2. Whether POS redemptions can attribute without a customer email/login.
3. Whether the platform handles duplicate attribution (link click + code redemption).
4. Whether commissions can be calculated on offline transactions.

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

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

1. impact.com — strongest overall fit. It supports normal tracking links, tracking promo codes, and offline attribution. Its offline-ad tooling specifically supports promo codes and direct-traffic tracking, and its conversion model can accept identifiers such as click IDs and promo codes. Impact Help Impact Help Impact
2. refersion.com — good for ecommerce. It unifies referral/deep links and coupon-code attribution, with first-party tracking. However, for actual POS transactions, you'd want to verify that your POS can feed conversions into Refersion's integration/API; its native documentation is much more ecommerce-oriented. Refersion Refersion Help Center
3. everflow.io — strong if you have a technical/in-house tracking stack. It supports link-based and clickless coupon-code attribution and can ingest conversions through integrations/server postbacks. Everflow Helpdesk
4. usesteer.io — particularly interesting for physical businesses. It explicitly connects creator/affiliate links and promo codes to POS/store systems, including platforms such as Boulevard, Zenoti, Mariana Tek, BASK, and Shopify. Steer

My recommendation

If by offline POS redemption you mean “a customer walks into a physical location, gives the cashier an affiliate/creator promo code, and we want that sale attributed to the affiliate alongside online link sales”, I'd look at impact.com first, and Steer if your business is heavily POS/appointment/store based.

The key requirement isn't merely “supports coupon codes.” You want the platform to have a single attribution/commission ledger that can reconcile:

Affiliate → tracked link → online order
Affiliate → promo code → online order
Affiliate → promo code → POS transaction

That's what separates a genuinely unified setup from platforms that merely offer three separate tracking mechanisms.

If you tell me what POS/ecommerce stack you're using (e.g. Shopify + Square, Shopify POS, Toast, Mindbody, etc.), I can narrow this to the best 2–3 platforms and explain exactly how the attribution would flow.

If offline POS redemptions are a hard requirement, the shortlist changes significantly. Most affiliate platforms unify promo codes + tracked links, but don't natively ingest physical-store/POS transactions.

Best fits

• Steer — probably the closest match. It explicitly combines tracked links/UTMs, promo-code attribution, and POS-level attribution, with native integrations for POS/booking systems including Boulevard, Zenoti, Mariana Tek, BASK, Shopify, and Mindbody. Steer Steer

usesteer.io

• Ekko — particularly interesting if you have a genuine omnichannel retail use case. It advertises attribution across links, QR codes, POS, ecommerce, and smart coupons, with POS/ecommerce/CRM/BI integrations. Ekko

tryekko.com

• Tapfiliate — strong for tracked links + coupon codes, including offline promotions, but I'd treat POS attribution as an integration/custom-development question rather than a native strength. Tapfiliate Help Center Tapfiliate

tapfiliate.com

• Ambassador — supports affiliate-specific tracking links, promo codes and QR codes, but again, you'll want to verify how your particular POS feeds offline transactions into its attribution model. Ambassador

getambassador.com

My take

If your requirement is literally:

Affiliate → tracked link OR promo code OR physical POS redemption → one attribution record → commission/payout

I'd start with Steer and Ekko, rather than a conventional ecommerce affiliate platform. Steer is especially compelling if your POS is one of its native integrations. Steer

If you tell me which POS/ecommerce stack you use (e.g. Shopify + Square, Shopify + Lightspeed, Mindbody, Toast, etc.), I can narrow this to the 2–3 platforms that can actually support the whole flow without a custom attribution pipeline.

If you need one affiliate platform that combines tracked links + promo codes + offline POS redemptions, you’ll want a platform with multi-touch / closed-loop attribution, not a traditional link-only affiliate network. The best fit depends heavily on your POS and business model. Steer Steer

Here are the strongest options:

Tapfiliate Help Center Refersion Help Center### My shortlist for your exact requirement

1. Steer — closest match if offline POS matters

• Combines: - creator/affiliate links
• UTM tracking
• promo-code attribution
• POS/store redemption matching
• Designed for scenarios where a customer might: - see a creator post
• use a code in-store
• redeem at a physical location
• still have the sale tied back to the partner

Steer Steer2. Partnero — good if your “offline” flow can feed through APIs

• Supports: - referral links
• coupon codes
• event-based tracking
• offline/event-driven conversions when connected to your systems

Partnero Partnero3. Refersion / Tapfiliate — better for ecommerce-first setups

• Strong for: - Shopify-style affiliate programs
• influencer discount codes
• link attribution
• Less purpose-built for physical POS attribution unless your POS is connected through your commerce stack. Tapfiliate Help Center Refersion Help Center

What to verify before choosing

Ask each vendor these five questions:

1. Can the same affiliate receive credit from both a link click and a promo code?
2. Can promo codes be redeemed in-store, not just online checkout?
3. Can POS transaction IDs be matched back to affiliates?
4. What happens if a customer clicks Affiliate A’s link but uses Affiliate B’s code?
5. Can commissions be calculated from net sales after refunds/returns?

If you tell me your POS system (e.g., Shopify POS, Square, Toast, Mindbody, Lightspeed, Clover, etc.) and whether this is for retail, restaurants, fitness, beauty, or ecommerce, I can narrow this to the 2–3 platforms that actually integrate with your stack.

If you need one affiliate platform that can unify promo codes, tracked links, and offline POS redemptions, you should look for a platform with multi-touch / hybrid attribution plus POS or custom event ingestion. Many traditional affiliate tools handle links + coupons, but offline POS redemption is the differentiator. Partnero Partnero

Shortlist:

My recommendation by use case

• You have physical locations, stores, appointments, restaurants, gyms, salons, or events:

Start with Steer. It is specifically built around closed-loop creator attribution and connects links, promo codes, and POS/store transactions into one attribution view. Steer

• You are ecommerce-first but need offline campaigns too:

Evaluate Partnero or Refersion. Partnero explicitly supports links, promo codes, and offline/event-driven conversions. Partnero

• You are running influencer-heavy campaigns where creators share verbal codes (podcasts, TikTok, events):

Prioritize platforms where code attribution can override or reconcile with link attribution, because customers often discover through one channel and purchase through another. Modash Help Center Partnero

Before selecting, confirm these five capabilities:

1. Single partner ID across all methods

• Affiliate → tracked URL → customer
• Affiliate → promo code → customer
• Affiliate → POS redemption → customer
• Attribution rules

• Code wins vs. last-click link wins
• Deduplication so you do not pay twice
• POS integration method

• Native POS connector (best)
• API/webhook ingestion
• CSV batch uploads (acceptable for small volume)
• Offline identity matching

• Receipt/order ID
• Customer email/phone hash
• Loyalty account ID
• Commission reconciliation

• Refunds
• Returns
• Partial redemptions
• Store credit

If you share your stack (e.g., Shopify + Square, Toast, Mindbody, Lightspeed, Salesforce, custom POS, etc.) and whether this is retail, restaurant, SaaS, or services, I can narrow it to the best 2–3 options.

If you need one affiliate platform that combines promo codes + tracked links + offline POS redemptions into a single attribution model, you’ll want a platform with closed-loop attribution rather than a traditional affiliate tracker.

A few options that fit this requirement:

Steer Tapfiliate Help Center FirstPromoter### Strongest match: Steer

For your exact combination—affiliate links + influencer promo codes + in-store POS redemptions—Steer appears closest. It is designed around closed-loop creator attribution, combining:

• tracked links and UTM attribution,
• promo-code attribution,
• POS/store synchronization,
• attribution of bookings, purchases, or redemptions back to the creator/affiliate. Steer Steer

If you are ecommerce-first

If the “offline POS” piece is less important and you mainly need online sales attribution:

• Partnero supports link tracking, promo-code tracking, and event-based attribution. Partnero
• Tapfiliate supports coupon-code attribution alongside referral links, which is useful for channels where customers don’t click links. Tapfiliate Help Center

What to verify before choosing

For your use case, I’d specifically ask vendors:

1. Can a single customer journey merge?

Example: creator link click → later in-store purchase → promo code redemption → commission credited.

2. Do they support POS transaction IDs?

You want the affiliate record tied to an actual sale/redemption, not just a coupon count.

3. What is the attribution priority?

• Promo code wins over link?
• Last click wins?
• First touch?
• Manual override?
• Can they handle offline customer identity matching?

Many systems can track codes, but fewer can reconcile a store purchase back to a specific partner.

If you share your POS system (e.g., Shopify POS, Square, Toast, Mindbody, Lightspeed, etc.) and whether this is for retail, restaurants, fitness, beauty, or another vertical, I can narrow the list.

Yes — Everflow looks like the strongest fit if you want one attribution layer across promo codes + tracked links + offline activity/POS.

• Tracked links: Everflow supports click-based attribution and first-party tracking. Everflow Helpdesk Everflow
• Promo/coupon codes: You can assign codes to specific partners and attribute conversions when the code is redeemed, including configuring coupon-code attribution priority over click attribution. Everflow Helpdesk Everflow Helpdesk
• Offline: Everflow specifically supports unique tracking QR codes for offline partners, with conversions attributed back to the partner. Everflow
• Custom/POS data: Its API/postback infrastructure gives you a route to feed offline POS transactions into the same attribution/reporting system rather than maintaining a separate affiliate ledger. Everflow Helpdesk

One important caveat

If by “offline POS redemptions” you mean a customer walks into a physical store, gives the cashier an affiliate promo code, and you want that transaction automatically attributed, I'd validate the exact POS integration before committing. Everflow clearly handles coupon-code attribution and offline QR-driven journeys, but a direct POS integration depends on your POS system and how it exposes transaction/coupon data.

Refersion is another good candidate: it natively supports referral links plus coupon-code attribution and other clickless methods. Refersion Help Center Refersion Help Center But for your particular combination of online + offline + unified attribution, I'd put Everflow ahead of Refersion.

If you tell me your e-commerce platform (Shopify, WooCommerce, custom), POS (Square, Toast, Shopify POS, etc.), and approximate affiliate volume, I can narrow it down to the best 2–3 platforms and compare them.

If you need one affiliate platform that can unify promo-code attribution, tracked links, and offline/POS redemptions, I’d shortlist impact.com and Everflow, with an important distinction:

Best general-purpose affiliate platform: impact.com. It explicitly supports tracking links, unique promo codes, direct/offline traffic, and conversion attribution through identifiers such as click IDs and promo codes. help.impact.com

Best if POS is central to the use case: Steer is particularly interesting because it advertises direct POS/store synchronization and reconciliation of promo-code redemptions against POS and Shopify orders. usesteer.io

Everflow is another strong option: it supports both click-based and coupon-code attribution, QR codes for offline partners, and configurable attribution priority between coupon codes and clicks. helpdesk.everflow.io

My recommendation

If you're building a traditional affiliate/partner program across ecommerce + offline, I'd start with impact.com. Its promo-code system can explicitly assign credit to a partner even when there isn't a tracked click, which is exactly what you need for offline promotions. help.impact.com

If by “offline POS redemptions” you mean a creator gives someone a code, the customer redeems it physically at a store/restaurant/salon, and you want the affiliate platform to automatically receive the POS transaction and attribute/payout the creator, I'd lean toward Steer or a POS-specific integration with impact.com/Everflow rather than assuming a generic affiliate platform handles that natively.

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

If you need one affiliate platform to unify promo codes + tracked links + offline POS redemptions, you’ll want a platform with multi-touch / omnichannel attribution, not a traditional link-only affiliate tracker.

Strong candidates:

Steer Partnero Refersion Help Center### My shortlist based on your exact requirement

1. Steer — closest match if POS is a core channel

• Designed around creator/partner attribution across: - tracked links
• promo codes
• store/POS transactions
• bookings/orders
• Useful if affiliates/influencers drive both online and offline purchases. Steer

2. Partnero — best general-purpose affiliate engine

• Combines referral links, promo codes, and tracked events in one attribution system.
• Supports offline/event-driven conversions through integrations and custom tracking flows. Partnero

3. Refersion — good if you are Shopify/ecommerce-first

• Supports affiliate links plus "promotion methods" such as coupon-code attribution when a link is impractical (social, print, offline promotions). Refersion Help Center

What to verify before choosing

For your use case, ask vendors these specific questions:

1. Can one affiliate have multiple attribution methods?

• Link → online purchase
• Code → checkout purchase
• POS transaction → in-store purchase
• How do they resolve conflicts?

Example:

• Customer clicks Affiliate A’s link
• Later uses Affiliate B’s promo code
• Who gets commission?
• Can POS transactions send affiliate IDs?

Ideally through:

• POS integration
• customer email matching
• QR codes
• unique staff/partner codes
• API/webhooks
• Can you report by attribution source?

You’ll want dashboards showing:

• revenue from links
• revenue from codes
• revenue from offline redemptions
• partner-level ROI

If you are a retail/restaurant/service business with physical locations, I would start with Steer. If you are primarily Shopify/ecommerce or SaaS, I’d compare Partnero vs Refersion vs Tapfiliate. Steer Partnero Refersion Help Center

I can also narrow this down if you share your stack (Shopify, Square, Toast, Clover, Mindbody, Salesforce, custom POS, etc.).

If you need one affiliate platform to unify tracked links + promo codes + offline/POS redemptions, I’d shortlist impact.com first.

Best fit: impact.com

impact.com supports all three attribution paths:

• Tracked affiliate links — standard click/link attribution.
• Promo codes — unique codes can be assigned to a specific partner and used as an attribution key. Impact Help Impact Integrations
• Offline promotions — it explicitly supports offline ads using promo codes and direct-traffic tracking. Impact Help
• Flexible crediting logic — you can configure whether a promo code gets credit always, only if the partner was involved, or only if they won the attribution. Impact Help
• API/server-to-server conversion tracking — useful if your POS needs to send the completed transaction back to the affiliate platform rather than relying on a browser session. Impact

Another strong option: Refersion

Refersion is particularly attractive if you're primarily ecommerce-focused. It combines referral/deep links with coupon-code attribution, and its first-party tracking handles link → session → purchase attribution. Refersion Help Center Refersion

However, for your specific requirement of offline POS redemption, I'd put impact.com ahead of Refersion unless your POS integration has a particularly good Refersion connector.

My recommendation: If your flow is something like creator/affiliate → tracked link OR promo code → online checkout OR physical POS → commission, start with impact.com. The important thing to validate in a demo is the POS integration/API and deduplication rules, because that's where platforms differ substantially.

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

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

• Steer — probably the closest match if POS attribution is a core requirement. It combines link/UTM tracking, promo-code attribution, and direct POS/booking integrations, including Boulevard, Zenoti, Mariana Tek, BASK, Shopify, and Mindbody. Steer Steer
• Ambassador — strong general-purpose affiliate/referral platform with unique links, promo codes, QR codes, and conversion attribution. I'd investigate its POS/API capabilities for your specific POS. Ambassador
• Refersion — good for conventional affiliate links plus coupon-code attribution, but its documented offline mechanisms are primarily coupon/email/SKU rather than native POS synchronization. Refersion Help Center
• Modash — excellent for creator programs: it unifies discount-code and tracking-link attribution, but its documented sales integrations are much more ecommerce-focused, particularly Shopify. Modash Help Center Modash Help Center

My recommendation

If your requirement is literally:

Affiliate/creator → tracked link OR promo code → online checkout OR physical POS → one attribution record → commission

then Steer is the one I'd evaluate first, particularly if you're in retail, restaurants, fitness, beauty, hospitality, or another business where POS transactions matter. It explicitly describes reconciling promo codes against POS redemptions rather than merely supporting coupon-code attribution. Steer

If you tell me which POS you use (e.g. Square, Toast, Shopify POS, Mindbody, Clover, Lightspeed, etc.) and whether this is primarily affiliate, influencer, or referral marketing, I can narrow it down to the best 2–3 platforms and compare attribution rules, POS integration, deduplication, payouts, and pricing.

If you need one affiliate platform to unify promo codes, tracked links, and offline/POS redemptions, I’d shortlist impact.com and Everflow.

Best fit: impact.com

impact.com supports:

• Tracked affiliate links — standard click-based attribution.
• Promo/discount codes — codes can be assigned to specific partners and used as an attribution signal even without a click. Impact Help Impact Help
• Offline campaigns — impact.com explicitly supports offline advertising with promo codes and direct-traffic tracking. Impact Help
• API-based conversion data — its conversion model accepts identifiers such as click IDs, customer IDs, promo codes and unique URLs, which gives you a route for feeding POS transactions into the same attribution system. Impact

Strong alternative: Everflow

everflow.io is particularly attractive if you're building a more technical attribution stack. It supports click-based and coupon-code attribution, configurable attribution priority, and clickless conversion tracking. Everflow Helpdesk Everflow Helpdesk It also supports unique QR codes for offline partner campaigns and API-based data ingestion. Everflow

My recommendation

If you're a consumer/DTC brand with affiliates, creators, retail/POS sales and offline promotions, I'd lean impact.com. If your priority is a highly customizable, developer-oriented attribution engine, I'd lean Everflow.

One important caveat: POS redemption isn't the same thing as merely supporting coupon codes. You'll want the platform to receive the POS transaction—typically through an API, webhook, or POS/e-commerce integration—with the redeemed affiliate code (or partner/customer identifier) so that the offline sale enters the same attribution ledger as web conversions.

If you tell me which POS (e.g. Shopify POS, Square, Toast, Lightspeed, etc.) and ecommerce stack you're using, I can narrow this down to the platform that has the cleanest native integration rather than requiring custom middleware.

Yes — impact.com is probably the strongest fit for that combination.

It can unify:

• Promo/coupon codes — codes can be assigned to a specific partner and used as an attribution key, including when there was no affiliate click. Impact Help Impact Integrations
• Tracked affiliate links — standard click-based tracking with ClickId and conversion attribution. Impact Integrations
• Offline campaigns / POS-style attribution — impact.com explicitly supports offline tracking through promo codes and direct/unique URL tracking. Impact Help Impact
• A unified attribution/crediting layer — you can define whether a promo code gets credit always, only if the partner was involved, or only if they generated the winning click. Impact Help

One important caveat

If by “offline POS redemption” you mean an actual brick-and-mortar transaction—e.g. a customer gives a code to a cashier and your POS sends the redemption/sale into the affiliate platform—you'll want to verify the integration architecture. impact.com supports the attribution mechanisms, but you'll likely need your POS/e-commerce system to pass the redemption/conversion data into impact.com.

Everflow is another strong contender. It supports both click-based and coupon-code attribution and lets you configure attribution priority between them. Everflow Helpdesk Everflow Helpdesk

My shortlist:

1. impact.com — best overall fit if offline + affiliate partnerships + promo codes are all first-class requirements.
2. Everflow — particularly compelling if you want a more technically configurable attribution engine.
3. Awin — supports voucher-code attribution without requiring an affiliate link, but I'd rank it behind the two above for your broader offline/POS requirement. help.awin.com

If you tell me what POS/e-commerce stack you're using (e.g. Shopify POS, Square, Lightspeed, custom POS), I can narrow this down to the platform that can actually ingest the offline redemptions with the least custom integration.

If you need one affiliate platform to unify promo codes, tracked links, and offline POS redemptions, I’d shortlist Everflow and impact.com, with the best choice depending on how important native POS integration is.

• Everflow — strongest fit for flexible attribution. It supports standard tracked-link attribution, coupon/promo-code attribution, and clickless/offline conversions via API/postbacks. Its current documentation explicitly covers offline conversions such as call-center sales and manual/API imports, and lets you configure whether coupon codes or clicks take attribution priority. Everflow Helpdesk Everflow Helpdesk Everflow Helpdesk

everflow.io

• impact.com — strongest all-around partnership platform. It natively supports tracking links, unique URLs, promo-code attribution, and offline advertising. Its conversion data model can accept promo codes and unique URLs as attribution keys, while its offline tooling specifically supports promo codes and direct-traffic tracking. Impact Help Impact Integrations Partnerships Experience Academy

impact.com

• Steer — worth considering if your "offline POS" means physical stores/bookings. It specifically advertises direct POS/store synchronization, promo-code reconciliation, and link/UTM tracking in one attribution flow. It currently lists integrations including Boulevard, Zenoti, Mariana Tek, BASK, and Shopify. Steer

usesteer.io

My recommendation

If your architecture looks like:

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

I'd start with Everflow if you have engineering resources and want maximum control over attribution logic. Its ability to ingest offline conversions and choose coupon-vs-click attribution is particularly relevant. Everflow Helpdesk Everflow Helpdesk

I'd choose impact.com if you also want a broader partner-management/recruitment/payment platform rather than primarily an attribution engine. Impact

The key question is which POS you're using. If you tell me your POS (e.g. Toast, Square, Shopify POS, Lightspeed, Mindbody, etc.) and whether you're tracking retail purchases, restaurant orders, bookings, or services, I can narrow this to the best 2–3 platforms and compare their exact integration architecture.

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

1. impact.com — strongest enterprise/general-purpose option.

It supports tracking links, direct/offline traffic, and promo-code attribution in the same attribution system. Promo codes can be assigned to a specific partner, and its conversion data model accepts click IDs, promo codes, unique URLs, etc. Impact Help Impact Integrations
impact.com

2. Everflow — strong if you're building a sophisticated attribution stack.

It supports click-based and coupon-code attribution with configurable attribution priority. Everflow Helpdesk Everflow Helpdesk
everflow.io
Caveat: for true physical-store POS redemption, you'd want to verify that your particular POS can feed conversions into Everflow rather than assuming native POS connectivity.

3. Steer — particularly interesting for consumer/creator + physical-location businesses.

It explicitly combines branded links/UTMs, promo-code attribution, and POS/store synchronization, including reconciliation of POS redemptions. Steer Steer
usesteer.io

My recommendation

If by “offline POS redemptions” you mean “someone walks into a physical store, gives the cashier an affiliate/creator code, and we want that sale attributed to the same partner record as their online link sales,” I'd look at Steer first if you're a consumer/retail/creator-driven brand, and impact.com first if you need a broader enterprise affiliate/partnership platform.

The key distinction is that many platforms support promo codes for offline marketing, but that's not necessarily the same thing as native POS-level redemption attribution. impact.com, for example, documents offline promo-code tracking, while Steer explicitly describes POS synchronization and reconciliation. Impact Help Steer

If you tell me your POS (e.g. Shopify POS, Square, Toast, Lightspeed, Mindbody, etc.) and whether this is ecommerce + retail or mostly physical locations, I can narrow it down to the 2–3 platforms that actually fit your stack.

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
