​
How it works

Every payment in Retempo flows through a predictable five-stage pipeline. You define what you’re selling and how to price it, Retempo handles checkout and invoicing, and Arc records the final settlement proof onchain.
1

Service

Create a service that represents what you’re selling — an API, a SaaS tool, or an AI agent capability.
2

Payment Plan

Attach a payment plan to the service that defines the price, billing interval (monthly, weekly, daily, or one-time), and currency (USDC).
3

Checkout Session

Generate a checkout session link to onboard a subscriber. When the subscriber completes checkout, a subscription is created automatically.
4

Invoice

Retempo issues an invoice for each billing cycle. Invoices move from DRAFT → OPEN → PAID as payment is processed.
5

Settlement

A settlement is submitted to Arc (Chain ID 5042002), where the transaction is recorded onchain. Once the Arc transaction is confirmed, the linked invoice is marked PAID.
All amounts in Retempo are denominated in USDC. Every settlement proof is recorded onchain on Arc (Chain ID 5042002), giving you a verifiable, tamper-proof record of every payment.
