});The missing middle
Payments move money. Subscriptions assume credit cards. Your app still needs a wallet.
Users in Africa buy prepaid. Gateways settle cash; global billing assumes App Store or Stripe subscriptions. Neither gives you balances, rate cards, or top-up UI. Developers rebuild that stack for weeks — Jaza ships it.
Gateways
PawaPay, Paystack, Flutterwave move cash. They do not hold credit balances or ship wallet UI.
Global billing
RevenueCat and Stripe Billing assume App Store subscriptions and B2B metered SaaS — the wrong default for prepaid Mobile Money.
Jaza
Immutable ledger, rate cards, drop-in wallet UI, and a consume API your backend calls on every billable action.
How it works
Meter usage. Top up prepaid. Charge from your API.
African apps need fuel wallets, not monthly lock-in. Jaza is the ledger and wallet UI between your product and the payments your users already trust.
- 01
Set credit prices
Define what each action costs — SEND_SMS = 2 credits, AI_PROMPT = 10. Your product economics, your rate card.
- 02
Users top up with Mobile Money or cards
MTN, Airtel, Orange, M-Pesa, and cards. When the payment webhook lands, Jaza credits the wallet instantly.
- 03
Your backend consumes credits
Call jaza.consume() from your server. Idempotent, race-safe deductions — balances update live. No custom ledger to maintain.
