Ecom Heads
You're leaving ~$10K/month on the table after every order
After checkout, the card is charged, the guard is down, and your customer is in a buying mindset. Most stores respond with a receipt. The operators who've figured this out are adding 5-6% to AOV with zero ad spend.

The Setup
If you're on Shopify: between payment confirmation and the Thank You page, you can drop a product offer. The buyer accepts with a single click, no re-entering payment info. Shopify uses the vaulted card. If they accept, it's added to the order. If they don't, nothing changes.
ReConvert's 2023 benchmark across 40,000+ brands puts the average one-click conversion rate at 4.7%, with top-decile operators hitting 28.3%. Average AOV lift for stores using this: 5.6%.
The math
2,000 orders/mo × $90 AOV × 5.6% lift = ~$10,000/month
No new traffic. No new creative. No new SKUs.
Quick caveat: this data comes from an app vendor (ReConvert) with an obvious interest in publishing positive numbers. Treat it as directional. The mechanism holds up on its own. You're catching a buyer at peak intent, post-anxiety, wallet already out.
The Part Most Operators Get Wrong
The setup is simple. The offers are where it falls apart.
Generic cross-sells don't work here. If someone just bought a coffee grinder and you surface a phone case, you'll get near-zero conversion and friction at the worst possible moment. The offer has to logically extend what they just bought.
Match the offer type to what they're buying:
Run a two-step funnel: primary upsell, then a downsell if they decline. Most platforms allow up to three offers per checkout. Most operators who've dialed this in run two steps.
Why You Probably Haven't Done This
Technical friction that no longer exists.
Building real one-click post-purchase used to require developer work or clunky workarounds. Apps like ReConvert, AfterSell, and Zipify OCU are install-and-configure. Operators report going live in under a day.
Your attention goes upstream.
Growth teams obsess over ad creative, landing pages, cart abandonment. Post-purchase is after the "win," so it gets nothing. The revenue it generates doesn't show up in ad attribution dashboards.
Fear of disrupting the experience.
Legitimate concern, but only for bad implementations. Irrelevant offers don't just fail to convert; some operators report they increase support tickets. A relevant, one-click offer has almost no friction.
The Timing Angle
If you're on Shopify: the platform deprecated checkout.liquid for Plus stores on August 28, 2025. Non-Plus stores have until August 26, 2026. If you're already rebuilding your Thank You and Order Status pages, set up the upsell while you're in there.
One newer development: AfterSell was acquired by Rokt in 2024. They added a layer called Rokt Thanks that lets brands earn revenue from third-party offers on the thank you page, even from customers who skip your own upsell. Most operators don't know about it.
One Real Limitation to Know
Post-purchase offers don't fire for Apple Pay, Google Pay, Amazon Pay, installment services, or multi-currency/duties orders. Some verticals are at 40%+ wallet checkout usage, and those buyers bypass the upsell entirely.
Fix: a post-purchase email or SMS sequence for wallet shoppers. One 2-email sequence targeting non-upsell buyers closes that gap.
What to Do Next Week
1
Audit your checkout share by payment method. That's your coverage gap.
2
Pick the right offer type for your top SKU using the framework above. ReConvert has a free plan; Zipify OCU has a 30-day trial.
3
Build the email/SMS fallback for wallet pay buyers.
Start with one SKU, one offer, and measure attach rate for two weeks.
