✊ Motivation

Revenut is being developed as a lightweight, open source alternative to Stripe's mobile app after my SaaS¹ experienced fraudulent activity in the form of card testing. Many other Stripe customers have voiced their problems with card testing too²³ and although Stripe confirmed card testing has ceased on my website, the problem persists where fraudulent transactions and customers are still included in Stripe's mobile app reporting. As a result, the numbers and charts displayed simply do not reflect actuals.

Unfortunately Stripe is unable to modify the revenue data or financial reports on the dashboard at this point so the Stripe mobile app, as convenient and fast as it is, does not accurately display metrics including Gross Volume and New Customers.

I looked into using another SaaS analytics service but they all charge a premium amount and still do not provide some of the metrics I find useful for my freemium business model. I then decided to build Revenut and open-source it so fellow SaaS owners can get accurate and transparent SaaS metrics conveniently at no cost.

🚦 Authentication

Revenut uses Expo's built-in Authentication package that has been configured to use Stripe's browser-based authentication via OAuth. This allows Stripe users to login with their existing Stripe credentials securely so Revenut can retrieve data required to formulate its metrics.

🧭 Roadmap

SaaS owners can generate revenue from multiple sources including app stores, advertisements and more. Revenut should be updated to forecast revenue from these providers:

• Stripe
• PayPal
• Google AdSense
• Apple App Store
• Google Play Store
