A Shopify app · pre-purchase and post-purchase upsells
One flat price.
Unlimited orders.
Every other upsell app charges you more as you sell more — by order tier, or by taking a cut of the revenue they helped you make. FlatUpsell charges one price, forever, however many orders you ship.

What your customer actually sees
The real offer, rendered by the app on a Shopify cart page — it borrows your theme’s font, colour and corner radius, so it belongs to your shop rather than sitting on top of it.
Two places to make the offer
One-click offers after payment
A second chance right after the payment goes through, before the thank-you page. They accept without re-entering their card, and the original order is never at risk.
You see what each offer earns
Shown, accepted, conversion rate and extra revenue — per offer, ranked by what actually brought money in. The ones that never get shown stay visible too.
Your storefront, not ours
The cart offer picks up your theme’s own font, colour and corner radius, so it reads as part of your shop rather than a bolted-on popup.
What growth costs you
Volume pricing punishes exactly what you are working for. Here is the same shop, growing, on AfterSell’s published tiers and on ours.
| Your volume | AfterSell | FlatUpsell |
|---|---|---|
| 500 orders / month | $34.99 | €14.99 |
| 1,000 orders / month | $54.99 | €14.99 |
| 2,000 orders / month | $99.99 | €14.99 |
| 25,000 orders / month | $779.75 | €14.99 |
Going from 500 to 2,000 orders a month triples their bill. Ours does not move. Prices are theirs, published on their own pricing page.
