Start with 10 credits.
0.1 USDC.

0.01 USDC per credit

No monthly subscription. Buy 10–100,000 credits at a time. Creating a payment window uses credits even if the invoice remains unpaid.

Renewal costs the same as creating a new window. Cancellation does not refund credits. Network and facilitator costs are separate from invoice credits and depend on the payment route.

0.2% on confirmed payments

Additional to invoice creation credits. The recipient receives the full USDC payment; the service fee is charged from the merchant’s prepaid credit balance, without another wallet transaction.

Before creating each invoice, keep enough available credits for its creation cost plus the success-fee reserve. Every open invoice has its own reserve. Confirmation consumes the reserve; cancellation or expiry of an unpaid invoice releases it. Pending verification keeps the reserve. Creation credits are not refunded.

The fee rate and credit conversion price are fixed per payment window. Renewal uses the current tariff. Existing invoices without a fee are not charged retroactively. Calculation, rounding and examples →

Estimate your total service cost

This calculator includes creation and success fees using one average amount for all invoices. It is not a subscription charge or a network-fee quote. Reserves are held funds within your credit balance, not an additional fee. Count renewals as additional windows. Package purchases are separate; unused credits remain in your balance. For more than 100,000 credits, purchases must be split into packages and remain subject to checkout limits.

Feature passes · same credits

Advanced merchant tools activate for 30 days from your prepaid credit balance. No automatic renewal and no wallet debit. Growth includes Branding, Analytics, Webhook Pro, Team and Extended Audit. Individual passes remain available. Upgrading converts unused individual-pass value, rounded down to whole credits, into a discount and extra prepaid time. The confirmed-payment rate stays the same. Webhook delivery has a 3-day expiry grace and a 30-day retained replay window; queued deliveries continue.

Core payment status, receipts, basic customer/AR tools, refunds, credit notes, security controls and the primary webhook remain available without a premium pass.

Who this is for

Businesses already paid in USDC: agencies, independent service providers and teams that need to match a payment to an order.

Applications and agents: create invoices for reports, digital services or completed work; check payment status before delivery.

The hosted product includes non-custodial refunds, customer/AR tooling and accounting exports for developer-built integrations. It still does not provide fiat conversion, USDT or automatic wallet debits. Payment receipts are not tax invoices.
