This applies to organizations in Mexico. When you issue an invoice under the PPD (Payment in Installments or Deferred) payment method, the SAT requires a “Payment Receipt Supplement” (REP) for every installment you receive.
What Cord does today
From the invoice detail page you can click Register Payment and enter the amount, date, and method. Cord adds that installment to the invoice balance, reflects it in the detail view and in collections, and marks the invoice as settled once the balance reaches zero.
If your sales are collected in full up front, invoice under the PUE method (Payment in a single instalment) instead of PPD: the REP doesn’t apply there, and Cord covers the full cycle with no extra manual steps.
