When you issue an invoice under the PPD (Payment in Installments or Deferred) payment method, the SAT requires you to generate a “Payment Receipt Supplement” (REP) every time the client sends you a payment.

Manual Generation

Since B2B clients typically pay large amounts via direct SPEI transfer to your bank:

1. Go to the Invoice in Cord.
2. Click on Register Payment.
3. Indicate the date the funds reached your bank account, the amount, and the receiving account.
4. Cord will stamp the REP based on that data and settle the invoice balance.

Automation via Webhooks (Stripe)

If the client pays the quote or PPD invoice using the card payment button (Stripe Checkout), Cord will listen to the checkout.session.completed webhook from your Stripe account. Upon receiving it, Cord will mark the invoice as paid and automatically issue the REP with the SAT without any action on your part.
