About Sweet Upsell

Increase your revenue on autopilot with post-purchase upsells on the order confirmation page - without the need for custom work or flow interruptions! If you're not using post-purchase you’re leaving money on the table. The order confirmation page is valuable real estate where Sweet Upsell can boost your revenue and average order value. Sell in quantity, use custom cross-sells, automatic best sellers and product repeat. We use the native Shopify pages so can use the payment provider you want!

Incredible results so far. Upsells are converting better than expected, work great with our existing post-purchase, and anytime we need help, support is there. Excellent app.

Next-level product with insanely fast support. Beautifully designed and highly recommended!!
— Trend Vibe
#1 UPSELL APP! Sweet Upsell makes upselling easier than ever, with a great dashboard, outstanding support, and excellent performance. We’re seeing nearly 2–3x higher revenue and conversion rates compared to our previous upsell app.
— Meow & Mooch
This is a robust and reliable upsell solution. Sweet Upsell integrates seamlessly into our checkout flow and has significantly improved our post-purchase revenue. The support team is a pleasure to work with.
— Petrix
We’ve had a very positive experience using Sweet Upsell. The platform is well designed, easy to manage, and delivers strong results without adding friction. Support is fast, professional, and clearly invested in helping us succeed.
— Add To Life
Top-tier upsell solution. Setup was easy, performance is excellent, and the support team goes above and beyond every time. Highly recommended.
— Omni Vault
Sweet Upsell has been an excellent addition to our tech stack. The post-purchase upsell functionality is intuitive, performs reliably, and has driven measurable improvements in both conversion rate and average order value. The support team is highly responsive and consistently provides thoughtful, effective solutions.
— Softbridge Technology
Only App we found that worked for our payment processor. Super convenient, took our AOV through the roof. The support is pretty good too, we were talking to a real person without any hassle.
— luxyeon
Good app, we're making a lot of money off it compared to the other guys we tried.
— ZRAs Mart
Just took 5 mins to install and paid for itself almost immediately. Love the direct integration to Shopify's api so it doesn't get in the way.
— Movo Next
A real solid app, does just what it says on the side of the box. Great support and no nonsense results.
— Nexgenia
Thank you so much!!!
— Hima Glow Tiles
I rarely leave negative reviews, but this customer support experience was unacceptable. We used the app for two years without issue, and then it suddenly stopped showing post-purchase. Instead of investigating or offering a solution, Jack from support gave vague, unhelpful replies and failed to address the problem. Messages went largely unanswered, and the overall attitude was poor — not how payin...

I’ve been trying to remove the app for days, but no matter what I do, I can’t seem to cancel it. I’ve contacted support multiple times, but I’m still getting charged and no one has helped me resolve the issue. It’s extremely frustrating and disappointing that I’m unable to get any assistance or stop the recurring payments. This is very poor customer service, and I would not recommend this app to a...

I am not happy of this app, because I uninstalled it, and it charge me for another full month. The app is very clunky, and the additional charge stings.
— Primerra
Impossible to communicate with and make changes such as canceling.
— CreativeCreation
Dear sweet uspell. Man man man, what a bad support not normal. Haven't had this bad since ages, they have a live chat where no one at all. There is also no email they respond to. And yes it will be something if they do respond to me now since I give 1 star. App works fine, just very expensive 30 euros a month. There are much better options.
— Concept Marseille
BEWARE OF THESE THIEVES!! Do not install this app! I installed the app for a day to test and on the same day I uninstalled it. Well, they have charged me for the entire month and after complaining to their customer service support they do not give me a solution. They took my money!
— Huellas de Ibiza
Installed the app and waiting for help from customer support for a week now. Would not recommend to use this.
— Mooska
Fairly easy to use and a good amount of control through Shopify's built in checkout customization options. Helpful staff if you ever have any questions, and are willing to make sure your checkout works at the best conversion rate it can.
