The two upsell placements that reliably lift average order value are the order bump beside the pay button and the one-click offer right after payment. Shopify's checkout supports the second through apps and mostly blocks the first. This page maps every placement, what it typically converts, and how to run all of them on a checkout you control.
| Placement | Buyer state | Typical take rate | On Shopify checkout |
|---|---|---|---|
| Cart drawer cross-sell | Still deciding | Low single digits | Theme apps, all plans |
| Order bump at payment | Decided, card in hand | Often 10-30% on a well-matched offer | Plus only, via UI extension |
| One-click post-purchase | Just paid, token live | Commonly 5-15% | All plans, via post-purchase apps |
| Thank-you page offer | Done, attention fading | Low | All plans |
Take rates depend on offer fit far more than placement; a refill of the product being bought beats a random accessory every time.
A tick-box offer beside the pay button with its own price and image, added to the same order before capture. Product names and prices read from Shopify so nothing drifts.
After capture, one offer, one button, charged to the tokenised card through the same gateway route. Accepted offers are appended to the Shopify order or written as a linked order.
Both are configured per store in the CascadeCheckout console, with rules by product, cart value and country. Because the checkout is yours, they work with every gateway you connect, including the ones Shopify's post-purchase framework skips.
Avoid offers that require a decision: comparison shopping at the pay button reduces the main conversion.
Measure average order value and checkout completion together. A bump that raises AOV by eight percent but lowers completion by four percent is a loss. Both numbers are on the store dashboard by route, device and offer.
Post-purchase one-click upsells work on all plans through apps. In-checkout order bumps need Plus, or a checkout you control.
A small add-on offer shown beside the pay button, added to the same order with one tick before payment.
No. Shopify's post-purchase framework skips some wallets and gateways. A custom checkout runs offers on every route it connects.
Yes. Accepted bumps are part of the order; post-purchase offers are appended or linked, depending on your setup.
