What happens if a customer stops paying?

Your app receives webhook events for each billing cycle, so you can gate access when a cycle is unpaid. Because payments are self-custodial and on-chain, there is no involuntary reversal of past payments.

Recurring billing

Recurring stablecoin payments

Q: How much does recurring billing cost?

It is free to open an account with no monthly fees. You pay 0.2% + $0.20 per payment collected, including each subscription cycle. Deposits are free.

Bill customers on a schedule in USDT and USDC with a Stripe-compatible API. Every cycle settles on-chain to a wallet only you control, with signed webhooks, refunds, and no chargebacks eating your revenue.

Recurring payments, in stablecoins

Subscriptions are the backbone of SaaS, memberships, and API businesses, and until now they meant card networks: chargebacks, declined cards, and processors that hold your balance. Recurring stablecoin billing changes the model. You charge in dollar-pegged USDT or USDC on a schedule you define, each cycle settles on-chain, and the money lands in a wallet only you control.

Sendbase exposes recurring billing through a Stripe-compatible API, so if your team has integrated Stripe before, the shape is familiar. You create a subscription with an amount and interval, then listen for signed webhooks to grant or revoke access as each cycle is paid. No chargebacks, fees far below cards, and full custody of every payment.

How it works

Set up recurring billing in four steps

1
Create a subscription
Define an amount, currency (USDT or USDC), and interval through the Stripe-compatible API or dashboard.
2
Collect each cycle
Each period a stablecoin payment is collected and settles on-chain to your self-custodial wallet.
3
Gate access by webhook
Signed webhooks tell your app when a cycle is paid, so you grant or revoke access automatically.
