We've had an excellent experience with Koin Store Credit & Rewards! The app has been incredibly useful for our business and has made managing store credit much easier and more efficient.

At Mundo del Comic, we use store credit on a daily basis, so having a reliable, well-designed solution that integrates seamlessly with Shopify makes a huge difference in our operations.

What really stands out is the outstanding customer support. Their team went above and beyond to help us create a custom Shopify Flow tailored specifically to our business needs. They were incredibly helpful, patient, knowledgeable, and genuinely interested in making sure everything worked exactly as we needed.

The app itself works wonderfully, but the level of support and willingness to help merchants find solutions is what truly makes it exceptional.

We're extremely happy with Koin and highly recommend it to any Shopify merchant looking for an efficient and flexible way to manage store credit. Five stars, well deserved!

We switched from a classic loyalty points program to a much simpler cashback system. It’s much more practical and easier to understand: you make a purchase, you earn cashback. Simple, clear and effective!

Team provided excellent support and the app looks to work great
