Should you pay affiliate commission on returns?

Should you pay affiliate commission on an order the customer sent back? For most brands the answer is no, and your programme terms should say so. The catch is on affiliate networks: the commission is only removed if you decline it in time. This guide covers what is fair, what the networks let you do, what it costs when you don't, and how to check last month in under an hour.

The short answer

Commission pays a publisher for a sale. If the sale is reversed, because the order was refunded or cancelled, there is nothing left to pay for. That is the logic behind the return and cancellation decline reasons the networks list.

What matters is how the commission gets removed:

• In-house affiliate apps usually do it for you, because they sit on your store and see the refund.
• Affiliate networks (Awin, CJ, Rakuten Advertising, impact.com and others) keep each sale pending for a set period. You have to decline or correct it before that period ends. After that, it is approved and paid.

So on a network, “should you pay commission on returns?” turns into “did you decline it before the deadline?”

In-house apps vs networks: why they behave differently

In-house apps run inside your store and hold the commission until the refund window has passed. A few examples, from the vendors’ own documentation:

• UpPromote creates a second referral with a negative amount to balance out a refunded one, which you then approve.¹
• Refersion has tools to negate an affiliate’s commission on cancelled orders, and advises holding affiliate payments until your return period ends.²
• Shopify Collabs uses a holding period during which the commission on cancelled and fully refunded orders is cancelled automatically.³

Networks work the other way round. The publisher’s sale is recorded by the network and waits for your validation. On Awin: “If a commission isn’t reviewed before the period ends, it will be automatically approved in line with your program’s auto-validation settings.”⁴ On CJ, corrections for last month’s transactions go in “before the 10th of the month for transactions which occurred in the prior calendar month”.⁵ On impact.com, “You cannot modify or reverse actions after they lock.”⁶

Some networks’ Shopify apps now send cancellations back for you, within limits. Awin’s app declines cancelled orders on Awin Classic accounts, for orders placed after activation, once Awin has whitelisted your store.⁷ CJ’s app has an opt-in automated order corrections feature, and Rakuten Advertising’s app automates cancellation reporting. Each one covers its own network only, and none of them decides what counts as a return under your terms. It is worth checking what yours actually caught.

What network terms allow

Declining a commission for a return isn’t a grey area on the big networks. It is one of the reasons they list.

Those are the networks’ own terms and codes.⁸ What your programme pays for is set in your programme terms, so make sure they say plainly that refunded and cancelled orders don’t earn commission, and how partial refunds are treated. Publishers accept declines far more easily when the rule was published before the sale.

How much it costs: a worked example

Take a brand with these monthly numbers:

• $80,000 of sales through affiliates
• an average commission of 8%
• 18% of those sales refunded or returned
• a quarter of those already declined today

The commission on refunded sales is $80,000 × 8% × 18% = $1,152. A quarter of it is already declined ($288), so $864 a month is paid on sales the brand didn’t keep. Over a year that is $10,368, before the network’s own fee on each approved sale.

An 18% return rate isn’t an extreme assumption. The National Retail Federation and Happy Returns estimate that 19.3% of online sales were returned in 2025.⁹ Your category may run higher or lower, so check your own Shopify returns report rather than trusting any average.

How to check last month

You don’t need new software to find out whether this applies to you. Four steps:

1. Export last month’s transactions from your network, pending and approved, with the order reference column.
2. Export last month’s orders from Shopify (Orders → Export → CSV), including financial status, cancelled date and refunded amount.
3. Match them on the order reference. Flag every transaction whose order is refunded, partially refunded or cancelled.
4. Add up the commission on the flagged rows, split by what is still pending (you can still decline it) and what was already approved (you paid it).

The step-by-step method for Awin, with menu paths and a spreadsheet formula, is in the guide to declining Awin commissions for returns. For the season where this costs the most, there is a dated routine in the holiday returns validation checklist.

Partial refunds, exchanges and store credit

Not every return is all-or-nothing:

• Partial refund: the customer kept part of the order. The fair outcome is commission on what they kept. On Awin you amend the sale amount to the new total, and the commission is recalculated; you don’t edit the commission directly.¹⁰ On CJ it is a partial correction; on impact.com, a modification.
• Exchange: the customer swapped a size or colour and kept the order value. There is usually nothing to decline.
• Store credit: the money stayed with you as credit rather than going back to the card. Whether that counts as a return is a policy choice. Decide it once, write it into your terms, and apply it every cycle.

The hard part with partial refunds is the maths across hundreds of rows. Refund matching works out the kept amount and the new commission per line, ready for the network’s amend column.

Keeping publishers on side

Publishers see your declines, and unexplained ones are the fastest way to lose a good partner. A few habits keep the relationship healthy:

• Give a reason on every decline, with something the publisher can check: “Order fully refunded on 12 Jan (refund #8812)”, not just “Returned”.
• Be consistent. The same rule every month, whoever does the validation.
• Validate on time. Declining at the last minute after weeks of silence feels worse to a publisher than a steady monthly rhythm.
• Share the rule up front. Put the returns clause in your programme terms and the network’s programme description.

Done this way, declining commission on returns is ordinary housekeeping, not a dispute.
