1. Describe the problem:
Payment processors like Stripe, Polar, and Lemon Squeezy handle the transaction layer well. But they leave a vacuum in the entitlement and consumption layer. There’s no seamless way to bridge a successful payment to a backend credit system.
Whenever I build a SaaS or product that involves credits, usage‑based pricing, or consumption tracking, I have to reinvent the wheel. I need to:
Every new project forces me to write the same custom infrastructure from scratch.
Whenever I build a SaaS or product that involves credits, usage‑based pricing, or consumption tracking, I have to reinvent the wheel. I need to:
- Synchronize payment webhooks with a user balance table
- Handle credit deduction logic
- Manage refunds and adjustments
- Avoid double‑spending, race conditions, and data inconsistencies
Every new project forces me to write the same custom infrastructure from scratch.
2. How often does the problem occur?
For every SaaS or product that:
This repeats every time I launch a new app.
- Is used by multiple clients
- Has payment processing through a customer portal (not one‑time sales)
- Includes credits, consumption, or granular pricing
This repeats every time I launch a new app.
3. What attempts have you made to solve the problem?
I tried solving it with raw code — connecting payment webhooks directly to the database. But the problem keeps repeating. There’s no reusable boilerplate or service I can plug in. Every new app means rewriting the same credit‑handling logic.
I looked at existing solutions — they are either too expensive or too complex for quick integration. And honestly, I’m tired of building this myself; I just want a ready‑to‑use API and move on.

4. How much are you willing to pay for the solution?
I’d pay $5/month as a baseline, scaling with the number of active users. A simple API that treats user balance as a first‑class citizen, abstracting the plumbing between payment events and the database, would save me weeks of development and maintenance.
