CASE STUDY · CHECKOUT ECONOMICS
We turned on Apple Pay. First-order AOV went down.
Apple Pay can quietly lower first-order AOV on Shopify if post-purchase offers are part of your funnel. Shopify doesn't surface the post-purchase page when a customer pays with a wallet or installment service: Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm, Afterpay. It's documented in Shopify's developer docs. At a DTC brand I run, Apple Pay grew to 56% of new-customer checkouts, and those customers came in with an 11% lower AOV, an 8% lower repeat rate, and a 10% lower LTV, because more than half of new orders could no longer see the one-click offer doing our AOV work. We turned it off. Before you enable wallets, price the tradeoff: the conversion lift has to beat the contribution you're switching off. For us, it didn't come close.
The advice everyone gives
Turn on express wallets. Fewer fields, faster checkout, less typing on mobile. Every CRO checklist has it near the top, and none of it is wrong. Apple Pay genuinely removes friction at the exact moment friction is most expensive.
We turned it on expecting a clean win. What the checklists don't mention is what the faster path skips on the way through.
The part nobody mentions
Shopify's post-purchase page, the screen where apps like Rebuy show a one-click add-on after payment, does not render for wallet orders. Straight from Shopify's developer docs:
"The post-purchase page won't be surfaced... [when] the customer chooses to check out with an installment service or a wallet service (such as Klarna, Affirm, AfterPay, Apple Pay, Amazon Pay, or Google Pay)."
The reason is mechanical. A one-click offer needs a payment method Shopify can charge a second time, and wallet payments don't leave one behind. So the moment Apple Pay went live, every customer who used it became invisible to our post-purchase offer. We didn't remove the upsell. We installed a bypass around it. By the time we ran the full analysis, the share of new customers even eligible to see a post-purchase offer had fallen 51%.
What the data said
We pulled a clean cohort: new one-time-purchase customers over a seven-week window, with subscription orders and BFCM discount codes excluded, so promo noise couldn't muddy the read. Then we split by payment method.
Same products, same traffic, same intent. The only difference was the page wallet customers never saw. And the offer they were skipping was not a rounding error: customers who said yes to a post-purchase offer ran a 53% higher AOV and a 46% higher net-sales LTV than customers who didn't. That's the offer side of the story I broke down in bundle builder vs post-purchase.
But don't bigger first orders slow down reorders?
Fair objection. If someone loads up at checkout, maybe they take longer to come back. We tested it at 30, 90, 180, and 365 days. Customers who took the post-purchase offer repurchased more at every horizon: 15% higher at 30 days, roughly 18% higher at 90 and 180, 17% higher at a full year. That's correlation, not a controlled trial. But the fear that upsells cannibalize the second order never showed up in our data. The opposite kept showing up.
The decision
For Apple Pay to pay for itself, its conversion lift had to outweigh 11% lighter orders, 8% fewer repeat purchases, and 10% lower LTV, applied to the 56% of checkouts that had moved to it. We could never isolate a conversion gain anywhere near that size. So we turned it off.
Not as a forever rule. As the result of a math problem. If wallet conversion someday clears the bar, it can come back. That's the posture I'd recommend over either camp: "wallets always on" and "wallets are bad" are both checklist thinking. The P&L decides.
Run this on your own store
- Split first-order AOV and post-purchase take rate by payment method. Lifetimely or a Shopify report gets you there in an afternoon.
- Watch eligibility, not just take rate. Our offer didn't get worse. It got unseen.
- Pull LTV by payment method at 90 days. The gap compounds past the first order.
- If wallets clearly win for your mix, move the money-maker pre-purchase: a cart cross-sell or in-checkout offer renders for everyone, wallets included.
- Re-run the math quarterly. Wallet share climbs on its own.
The faster checkout is visible. The offer it skips is invisible. Only your P&L sees both.
QUESTIONS
Asked and answered.
Why don't post-purchase upsells show for Apple Pay orders?
Shopify's post-purchase page only renders when the payment method can be charged again for the one-click add-on, which in practice means a standard credit card checkout. Wallets and installment services like Apple Pay, Google Pay, Amazon Pay, Klarna, Affirm, and Afterpay complete payment in a way that can't be re-charged, so Shopify skips the page entirely. This applies to every post-purchase app, Rebuy included. It's a platform limitation, not a setting you can change.
Should I turn off Apple Pay on my Shopify store?
Not by default: run the comparison first. We turned it off because Apple Pay had grown to 56% of new-customer checkouts while carrying an 11% lower AOV and a 10% lower LTV, and no conversion lift we could isolate came close to covering that. A brand without post-purchase offers, or with thinner ones, could land the other way. The point is to decide with the P&L, not the checklist.
How do I measure whether wallets are hurting my AOV?
Segment first-order AOV and post-purchase take rate by payment method, before and after enabling wallets. If wallet orders run consistently lighter and your take rate fell as wallet share rose, you've found it. In our case the tell was post-purchase eligibility falling 51% as wallet share climbed to 56%. Then put dollars on it: lost contribution per order, times wallet share, times order volume. Thirty minutes in Lifetimely or an order export answers it.
