Plus Checkout Upsell+Free Gift

Excellent checkout integration. Simple UI. Amazing sets of options & rules. Incredibly responsive support. A++ as far as apps go.

Thank you dear Jaap and all Upsell Plus team for a great support.
Jaap was available all the time to support and handle some slight issues that came by. Also they made some app changes a specially for us.

Best app for checkout upsells! Wow, and the support is great as well. It's converting at 8% so far in a few weeks of use. Improvements are happening often as well. The app creator understands upselling.

We've only just recently added this app to our store, just in time for BFCM period. It's almost caught us off guard just how valuable an app like this is and is making the team kick themselves for having not added something like this sooner! The app itself is very easy to use and setup. We've had multiple queries with their CS team who have been very helpful! It'd be great if the app updated it's performance on a more often than daily basis to monitor immediate performance from new offers placed online. Other than that, we can highly recommend this app and you'd be missing out on a large portion of revenue if you weren't to use the features this app has to offer.

Really easy to use and great support from their team to set it up! The best checkout upsell app I could find.

amazing customer service, super reactive, I totally recommend this app. And easy to set up compare to other apps

Jaap and his team have THE MOST responsive support that I've experience anywhere on the app store. UpsellPlus is easy to set up but don't let that fool you -- it is a powerful and complete upsell solution. Highly recommend.

We stumbled upon a fantastic app with excellent customer support. It's impressive how Jaap, the founder, shows genuine care for his customers, offering quick responses and eagerly meeting their requirements. The app is incredibly straightforward and reliable in its functionality. Without a doubt, it earns a five-star rating and comes with my strong recommendation.

Incredible support! Wow! They helped us translate the app to show it in both French and English!! Amazing support with custom stuff!

Not only does the app function exactly how we need, the support team is extremely responsive and assisted us with any questions we had. This is probably the easiest way to add an AOV boost to your store. If you don't have in-checkout upsells you're leaving tons of money on the table.
