One-Click Upsells Overview
Increase AOV with post-purchase upsell offers that customers accept with one tap
Last updated: 2025-01-16
One-Click Upsells are post-purchase offers that appear immediately after a customer completes checkout. Because the customer has already entered payment information, they can accept additional offers with a single click—no re-entering payment details required.
Why Post-Purchase?
Post-purchase upsells have significantly higher acceptance rates than pre-checkout offers because they don't interrupt the buying decision. The customer has already committed to purchasing, making them more receptive to related offers.
How It Works
- Customer completes checkout — Standard Shopify checkout flow
- Upsell page appears — Before the thank you page, customer sees your offer
- One-click acceptance — Customer taps "Add to Order" to accept
- Order updated instantly — Upsell item added to the original order
- Thank you page — Customer sees confirmation with all items

Best Practices
Optimization Tips
- Keep offers relevant — Upsells should complement the original purchase
- Use compelling discounts — 15-25% off works well for most products
- Test different products — What you think will sell may not be the winner
- Limit options — One clear offer converts better than multiple choices
- Mobile-first design — Most checkout traffic is mobile
