I’ve worked on a bunch of small apps over the years, and I kept running into the same problem:
I didn’t want to deal with subscriptions.
I just wanted a way to let users pay once for a set of uses—like 5 image generations, 10 API calls, or access to a feature for a day—and have the backend handle the usage tracking.
Stripe doesn’t really make that easy. Neither does PayPal. So I built Billivio.
What It Does
Billivio is an API-first service that lets you:
- Create one-time or multi-use access codes for your app
- Track how many times a user has used a code
- Handle refunds, promo codes, and expiration
- Keep full control of your payment flow and frontend
You use your own Stripe, PayPal, or whatever. Billivio just handles usage logic.
API Pricing
You don’t need a subscription to use it—just a balance. Calls are charged like this:
-
Create Purchase: $0.02 -
Log Usage: $0.01 -
Verify Code: Free
Minimum balance to go live is $5.
Free Credits for Early Users
Right now, if you sign up before pricing kicks in next week, you’ll get $10 in free credits—no credit card needed. That’s enough to build something and launch.
Try It Out
It’s still new, but functional. If you’re building something that should be pay-per-use instead of pay-per-month, feel free to try it out or send feedback.
