Plus Checkout Upsell+Free Gift

Jaap was always helpful and proactive helping us to set up the app across all our domains as our code base isn't easy to adapt to 3rd party apps. However, I believe out of the box UpsellPlus will meet many customers needs.

Great app for checkout and post purchase upsells. Works very well and doesn't bloat the storefront.

We were able to generate thousands of dollars of extra revenue thanks to this app.

best checkout app so far for Plus Merchants.
Jaap is also very patient and helpful!

very good custumer service, Jaap helped me with copying offers to other stores. will install in comming stores again.

Contacted Support and it was the Founder himself who helped us with our question regarding using the App. He was quick and very helpful. Also, the app is very easy to use and our issue was due to us not making sure that the item we had to upsell was in stock. All in all, great app and fantastic support.

A super responsive team -- willing to go above and beyond to ensure their app produces the results you want. Great working with Jaap so far!

Very easy to set up and the customer service has been second to none. We identified a small problem which was solved within a few hours. Jaap was brilliant!

I've had tons of questions and their customer service team is always there to assist. New apps can be tricky but their directions are on point and my customers are loving the deals we are offering.

Great app and great support team! I reached out about an issue I had and got an extremely quick response followed by very quick resolution! Would definitely recommend.

Overall, I highly recommend Upsell Checkout to any e-commerce business looking to increase their sales revenue. With its easy-to-use interface, flexible offer types, and powerful analytics, it's a great tool for boosting your bottom line.
