You will get a complete Stripe & Supabase token billing backend for your SaaS
Rising Talent

Project details
Hi there,
If you're building an AI SaaS or any app that uses a credit/token system, you probably know that connecting Stripe is the easy part. Building the actual token economy—tracking balances, expiring old credits, handling prorated upgrades, and fixing race conditions when users spend tokens at the same time—is a massive headache that takes weeks to code from scratch.
I've built a complete, production-ready Stripe + Supabase billing backend that solves this, so you can just focus on your core product.
Here is what I will set up for you:
1.Hybrid Billing: Support for recurring subscriptions (monthly/yearly) AND one-time token top-ups.
2.Strict Token Logic (FIFO): Secure database RPCs ensure users spend their oldest tokens first, with zero race conditions.
3.Auto Expiry & Refills: Built-in Supabase cron jobs automatically clear expired tokens and auto-refills monthly credits.
4.Reliable Webhooks: Safe handling of successful payments, failures, cancellations, and mid-cycle upgrades.
5.Growth Engine: A built-in referral system to auto-reward users for inviting paying customers.
