• Is customer retention your biggest challenge?

    You invest heavily to acquire customers, but they don’t return. You want to increase repeat purchases but lack a clear strategy to turn first-time buyers into repeat fans.

  • Stuck with a complex loyalty app?

    Trapped in a rigid loyalty system? You pay for features you don’t use while your customer data remains locked in a third-party platform.

  • Are constant discounts killing your profit?

    Discounts might cheapen your brand and train customers to wait for deals. This erodes margins and prevents you from building true, value-driven retention.

  • Want unlimited reward campaign flexibility?

    You need a flexible tool that brings your unique brand vision to life, not generic promotion templates that hold you back.

“Premier contact avec Rita de KOIN.
Intervention rapide et efficace. Je suis très satisfait et content du potentiel de cette app, ainsi que de sa simplicité à mettre en place.”

“Simple and easy to use and set up, the app is a really great surprise for marketing and offering cashback deals in a simple way. The only problem is that is too limited, you can't explore loyalty to customers and you can't set up campaigns to boost sales. The app issues store credit, but how you explore it? It's not clear for me yet.”

“I've been using Koin for about a month after finding out they use store credit to offer cashback or rewards. I immediately started working with their team on features my store needed, such as generating cashback after order fulfillment instead of at purchase to account for product swaps or order edits, and making cashback available for POS store clients. They have a great team that listens and collaborates on solutions for the store...”
