AddUp Checkout Customizer

I did not regret choosing this app. It's been a solid investment for online store. The app makes it simple to personalize every aspect of the checkout process. While the customization process is straightforward, I think the app could benefit from more in-depth documentation especially into more advanced features. Despite that , the support team was quick to assist when I needed help.
Overall the app delivers on its promise and it is a great choice for anyone looking to enhance their checkout.

My experience is very good. They charged a fee but it was worth it to me to gain the upsell in checkout. Also, I had some minor requests and they were very quick to reply and assist. They have a multitude of apps and I wish more features were combined into 1 app (cost savings) but the apps work great and super easy to install.
