Your September Returns Audit: Get Shopify Ready for the BFCM Surge

Black Friday 2026 falls on November 27, which means the return requests that follow it will start landing in your inbox before the holiday lights come down. Return volume typically spikes 25 to 45 percent in the weeks after Black Friday and Cyber Monday, right on top of the support ticket surge from the sale itself. If your returns and exchange flow is still running on last year's settings, September is the week to fix that, not November.

This post walks through what changed on Shopify's platform this season, why the return experience is now a bigger lever on repeat purchases than most merchants treat it as, and a five-step audit you can run before your BFCM campaigns go live.

The return surge nobody plans for

Online return rates have held at roughly 22.4 percent industrywide, according to a National Retail Federation and Loop Returns benchmarking report released jointly in August 2026, but the cost of processing each one has climbed roughly 18 percent year over year: carrier surcharges, reverse-logistics labor, and restocking goods that have already been worn or unboxed for a video all add up. That cost pressure lands hardest during the six to eight weeks after BFCM, when a full quarter's worth of returns can arrive in a single month.

The upside is that shoppers are telling retailers exactly what would keep them coming back. Narvar's 2026 Holiday Shopping Report found that 51 percent of shoppers say a hassle-free return experience would bring them back to a retailer after the holidays, but only 24 percent of retailers say they're investing in one. That gap is the opportunity: a returns flow that's ready before Black Friday becomes a retention channel, not just a cost center, while competitors are still fielding angry emails in December.

Why September is the right week to start

Shopify's own BFCM planning guidance frames September as the foundation-building month: the window when merchants who plan to run BFCM campaigns audit their store, confirm inventory, and set up the infrastructure the campaign will depend on. Returns and exchanges belong on that list alongside checkout and shipping, because a return policy you haven't tested tends to break exactly when order volume is highest and your team has the least slack to fix it manually.

Waiting until the week of Black Friday to touch your return settings means testing changes under live traffic. Waiting until December, when the return surge actually lands, means your team is improvising a fix while a backlog builds. September gives you a full sales cycle of runway to change something, watch it work on real orders, and adjust before volume triples.

What's new on Shopify's platform this season

A few recent Shopify releases directly touch the returns and exchange experience, and they're worth checking against your own setup before peak season:

• Exchange prompt on the return screen (POS 11.12, August 10, 2026). Staff now see a callout on the return item selection screen prompting them to add an exchange item, surfaced right where they're already working instead of buried in a secondary menu.
• Recent carts now support returns and exchanges (POS 11.13, August 17, 2026). In-progress return and exchange carts can now be saved, shared, and picked up from another device, the same floor-to-register flexibility sales carts already had. For POS Pro merchants with returns and exchanges enabled, that closes a real gap during a busy in-store rush after the holidays.
• Enhanced printed receipt editor (August 11, 2026). Return and exchange receipts now collapse into a single section with one summary amount, and the new editor adds built-in fields for return policies and signature lines without touching Liquid.

Full release notes are in Shopify's Retail Release Roundup. If you run a physical location alongside your online store, these are worth testing on the floor now, not on Black Friday morning. We covered the previous wave of POS returns changes in our guide to the unified POS returns cart, which is still the right starting point if you haven't configured returns and exchanges in POS at all.

One deadline is also worth flagging early: starting December 1, 2026, any returns app offering buyer-facing self-service has to authenticate through Shopify's Customer Account API to keep its Built for Shopify status. We wrote up what that means and what to ask your vendor back in July. If you haven't confirmed your app is compliant, September is a much better time to ask than November.

Make exchanges the default, not the afterthought

The financial case for exchanges over refunds hasn't changed, but the data behind it keeps getting more specific. Loop Returns' 2026 benchmarks, an analysis of 13.8 million returns across more than 4,000 Shopify stores, found US merchants converting returns to exchanges at a 17.1 percent rate on average, with the average exchange window running two days longer than the average refund window. Stores that lean harder into instant exchange flows report meaningfully higher conversion than that baseline.

The mechanism is simple: a refund ends the transaction, while an exchange keeps the customer's money in your store and gives them a reason to open the box again. We go deeper on how to structure this in our exchange-first strategy guide, but the September-specific version of that advice is about your return portal's UX: is store credit or exchange presented as the first, most visible option when a customer starts a request, or is refund still the default path with exchange buried below it? That's a five-minute audit that costs nothing to run.

It's also worth deciding now whether your holiday return window needs to stretch past your usual policy. Outdoor and apparel brand Huckberry, for example, extends returns placed between November 1 and December 31 so a gift bought during a Black Friday sale still has time to come back after it's been unwrapped weeks later. If your store sells anything people buy as gifts, a return-rules exception for that window (many returns apps, including Exchange It's Standard plan, let you set rules by time period, country, or product) is worth configuring before the sale starts, not after the complaints do.

The one tax trap to check before the next sales-tax holiday

Here's a specific, recent bug worth knowing about if you run exchanges through Shopify's native tooling: several states run back-to-school sales-tax holidays each August that exempt clothing under a price cap, and their tax rules explicitly say no additional tax is due when a customer later makes an even exchange, same product, different size or color, on an item bought during that window. In late August 2026, a merchant reported on the Shopify Developer Community forum that Shopify's returnCalculate API was charging full sales tax on those even exchanges anyway, because it recalculates tax as a brand-new sale on the current date rather than referencing the original order's exemption. Shopify staff confirmed the behavior and were still investigating a fix as of late August.

Sales-tax holidays aren't unique to August. Several states run them again around Halloween costumes, Energy Star appliances, or emergency supplies later in the year, and the same logic would apply to an even exchange made after any of them. If a customer books an exchange on an order that was tax-exempt at purchase, check that the exchange isn't quietly charging them tax the state says they don't owe. It's a small edge case, but it's the kind of thing that generates support tickets and refund requests you didn't budget for.

Your five-step September checklist

1. Extend your return window for gift purchases. Decide whether orders placed from November onward get extra time to account for gifting, and set the rule now.
2. Put exchange and store credit ahead of refund in your portal. Walk through your own return flow as a customer would. If refund is the first thing they see, that's costing you revenue you could keep.
3. Test the exchange flow end to end, including uneven exchanges. Confirm what happens when a customer swaps for a pricier item (do they get billed the difference automatically?) and a cheaper one (do they get a clean partial refund?) before volume triples.
4. Confirm your returns app's Customer Account API status. The December 1 Built for Shopify deadline is closer than it looks once BFCM eats your calendar.
5. Check tax handling on exchanges tied to any tax-exempt purchase. Even exchanges on holiday-exempt orders shouldn't pick up new tax; verify it rather than assume it.

None of this requires ripping out your current setup. It requires forty-five minutes with your own returns portal, in September, before order volume gives you an excuse to skip it. If you're evaluating whether your current app can handle return rules by time period, automatic uneven-exchange billing, and store credit as a real default option, Exchange It is built around exactly that workflow, integrated directly with Shopify's own Returns API rather than working around it.
