Hypothesis
Faster checkout is skipping something worth more.
Test
Split AOV and LTV by payment method, clean cohort.
Verdict
−11% AOV, −10% LTV. Turned it off.
The short answer
Shopify doesn't surface the post-purchase page when a customer pays with a wallet or installment service. 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.
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.
Shopify's post-purchase page, the screen where a one-click add-on shows after payment, does not render for wallet orders. It's documented in Shopify's developer docs: wallets and installment services don't leave a payment method behind that can be charged a second time.
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. The share of new customers even eligible to see the offer fell 51%.

net-sales LTV, with an 8% lower repeat rate
We pulled a clean cohort: new one-time-purchase customers over seven weeks, subscriptions and BFCM codes excluded. Then we split by payment method. Same products, same traffic, same intent. The only difference was the page wallet customers never saw.
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.
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 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. The P&L decides.
The faster checkout is visible. The offer it skips is invisible. Only your P&L sees both.
Why don't post-purchase offers 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 card checkout. Wallets and installment services complete payment in a way that can't be re-charged, so Shopify skips the page. A platform limitation, not a setting.
Should I turn off Apple Pay?
Not by default: run the comparison first. We turned it off because the math said to. A brand without post-purchase offers could land the other way. Decide with the P&L, not the checklist.
If it looks like a fit, we do one working session on your actual issue. You'll leave with something useful either way. If we both want to continue, we start. Most conversations don't turn into engagements.
