In your Shopify Admin, go to Settings → Checkout → Post-purchase page and select OfferEngine from the dropdown. This is required for upsells to appear after checkout.

FAQ

Frequently Asked Questions

Everything merchants ask before installing OfferEngine.

How does the AI recommendation work?
OfferEngine uses Shopify's native AI to analyze the items in the customer's cart right after checkout and automatically select the most relevant complementary product to offer. No manual configuration required.
What are U1, U2, D1 funnel steps?
U1 (Upsell 1) is the first offer shown after purchase. If the customer accepts U1, they see U2 (a premium second offer). If they decline U1, they see D1 (Downsell 1), a rescue offer with a higher discount to recover the sale.
Does it require theme customization or code?
No. Post-purchase extensions mount on Shopify's native secure post-purchase page, which appears before the Thank You page. There are no theme blocks, no liquid edits, and no code required.
Will it slow down my store or checkout?
No. The upsell page is hosted and served by Shopify's infrastructure. It only appears after payment is confirmed, so it has zero impact on your checkout conversion or page speed.
How does 1-click acceptance work?
Customers accept the upsell offer with a single click. Shopify securely charges their original payment method — the customer never has to re-enter card details.
What happens if the AI can't find a product?
OfferEngine falls back to the product you define in Global Settings (Fallback Matrix). This guarantees every customer always sees an offer, even when AI recommendations are unavailable.
How are accepted upsell orders tracked?
Any order that includes an accepted upsell receives an automatic 'OfferEngine - Upsell' tag in your Shopify Orders Admin, making it easy to filter and report on bonus revenue.
Does it work with Shopify Markets and multiple currencies?
Yes. The post-purchase extension uses Shopify's native checkout context, which respects the customer's market, currency, and language automatically.
