# Accept Payments

> Choose an onchain payment lifecycle for commerce checkout, agentic payments, reconciliation, refunds, and payouts on Base.

Accept payments on Base with the lifecycle your product needs. Use the [Commerce Payments Protocol](https://github.com/base/commerce-payments) to charge immediately or reserve funds in escrow before fulfillment, then capture, void, reclaim, or refund under payer-approved terms. The same solution area also covers scheduled collection, reconciliation, payouts, splits, and x402 APIs.

## Payment Lifecycle

| Stage | What happens | Start with |
| - | - | - |
| Charge | The operator collects and settles a protocol payment atomically | [Request a payment](/build-on-base/accept-payments/request-a-payment) |
| Authorize | The operator moves payer funds into escrow | [Authorize a payment](/build-on-base/accept-payments/authorize-a-payment) |
| Capture | The operator settles all or part of the escrowed amount | [Capture an authorization](/build-on-base/accept-payments/capture-an-authorization) |
| Confirm | Your backend verifies confirmed protocol events and claims the order once | [Verify a payment](/build-on-base/accept-payments/verify-a-payment) |
| Return or distribute | You refund the payer or pay downstream recipients | [Refund a payment](/build-on-base/accept-payments/refund-a-payment) |
