Where in the funnel it operates
Post-purchase and pre-purchase are different risk profiles, not competing products.
Best apps / Upsell & AOV
The Best Shopify Upsell & Cross-Sell Apps
Raising average order value is the cheapest growth there is, because you have already paid for the traffic. The catch is that a badly placed upsell trades a certain sale for a possible one.
THE SHORT VERSION
There are two genuinely different jobs here and they are often confused. Pre-purchase upsells run on the product page and in the cart, competing for attention with the sale you already had. Post-purchase upsells run after payment, where a decline costs you nothing. Most stores should start with the second, then add the first carefully. Work out what a lift is worth to you in the AOV calculator before you install anything.
What we judged on
The criteria below are the ones that actually change the outcome on a client store. Everything else is a feature list.
One-click acceptance
A post-purchase offer that asks for card details again is not a post-purchase offer, it is a second checkout.
Placement control
Inline offers convert without hurting conversion. Modals that block the buy button do the opposite.
Mobile behaviour
Most traffic is mobile, and upsell blocks are where mobile layouts break most often.
Margin visibility
You need to judge offers on profit contribution, not acceptance rate.
The picks
ReConvert
Best post-purchase upsellOur default for the thank-you page, which is the most under-used real estate on a Shopify store. The one-click post-purchase offer means no re-entered card, and the page builder lets you put the offer alongside genuinely useful things — tracking, a review prompt, a referral link. This is the lowest-risk AOV work available: the order is already banked before the offer is shown.
What is good
- True one-click offers with no re-entered payment details
- Thank-you page builder covers non-revenue wins too
- Downsell support when the first offer is declined
- A declined offer costs you nothing
What to watch
- Relies on Shopify's post-purchase extension — verify against your plan and checkout setup
- Easy to overload the page and undo the goodwill
- Extra items can complicate fulfilment if not checked first
Bold Upsell
Best pre-checkout upsellFor the offers that happen before payment — the larger size on the product page, the complementary item in the cart drawer. Bold is a long-established app with the placement control this job needs, which matters because the difference between an inline upgrade block and a modal is the difference between lifting AOV and denting conversion.
What is good
- Fine-grained control over offer placement
- Works in the cart drawer, the highest-intent pre-checkout moment
- Mature and well-supported
- Pairs naturally with a free-shipping progress bar
What to watch
- Genuinely easy to misconfigure into interruption
- Needs manual pairing work to produce relevant offers
- Costs conversion if you exceed one offer per stage
Selleasy
Lightweight alternativeSelleasy sits in the technology stack of several of our proposals as the lighter option — product-page and cart add-ons without much configuration overhead. It is a reasonable pick for a smaller catalogue where the pairing logic is obvious and you do not need the control Bold gives you.
What is good
- Quick to set up
- Handles both product-page and cart offers
- Low-friction pricing at small scale
What to watch
- Less placement control than Bold
- Fewer options as the catalogue and rules grow
Our verdict
Start with ReConvert on the thank-you page — it is the offer that cannot cost you a sale. Add Bold in the cart drawer once that is running, and cap yourself at one offer per stage.

Frequently Asked
Questions
What clients ask before they commit to an app in this category.
Post-purchase or pre-purchase upsells first?
Post-purchase, without much hesitation. The order is already complete, so a declined offer costs nothing — whereas a badly placed pre-purchase offer can cost you the original sale.
Can I run both apps together?
Yes, and plenty of stores do, because they operate at different points in the funnel. Just keep the total number of offers a shopper meets low.
How do I know an upsell is working?
Watch average order value and conversion rate together, and judge by profit contribution rather than acceptance rate. A heavily discounted upsell with a great take rate can still lose money.
