# Post-Purchase Upsells Built Into the Shopify Edit Flow
> AppFox shows product offers inside the order editing flow — the moment customers have full attention on their order and payment on file.
AppFox surfaces product offers directly inside the order edit flow — on your thank-you page and order status page, right where customers already land after checkout. When a customer opens their order to make a change, your upsell offer appears alongside it. One click adds the product to their existing order, no second checkout required, and any price difference is charged automatically on their original payment method.
## Why the edit moment converts
Most post-purchase upsell placements fail for the same reason: the customer has already moved on. A follow-up email lands in an inbox the customer has already forgotten about. A static thank-you page gets closed within seconds of the order number loading.
The edit flow is different. When a customer comes back to fix a shipping address or swap a size, they are fully inside their order — payment on file, intent proven, attention undivided. They're not browsing; they're engaged with a specific purchase they just made. An offer shown at that moment isn't an interruption, it's adjacent to what they're already doing.
One click accepts the offer and adds the item directly to their existing order. No second checkout, no new order number, no abandoned cart to chase — the edit settles on the original payment automatically.
## Key facts
An accepted offer is added directly to the existing order. No second checkout, no new order number, no re-entering payment details.
The price difference is charged automatically through Shopify on the customer's original payment method — no manual invoice needed.
Because the order is edited in place, Shopify Payments fees (1.5–2.9%) are never forfeited. Cancel-and-reorder flows lose those fees on every edit.
On Growth and Pro plans, AppFox automatically recommends relevant products based on what's in each order — no manual pairing required.
