An income invoice normally arrives without a Government Number. Lambda resolves PUE or PPD, reconciles the fiscal data, submits the selected route, verifies the CFDI, and starts file delivery.

​
Resolve PUE or PPD

Lambda uses this priority order:
  1. Recognized PUE or PPD values in direct custom fields on the AccountingInvoice.
  2. The CargoWise PostDate and DueDate as Mexico City calendar dates.
  3. A failure when the evidence is missing, invalid, or conflicting.
Direct custom values are trimmed and case-insensitive. Nested custom fields do not override the invoice-level values. Direct evidence wins even when the dates disagree. Date comparison uses calendar days, not elapsed hours. A PPD income CFDI uses SAT payment form 99, meaning the payment method will be defined later.

​
Normal path

1

Receive and capture

CargoWise outbound sends the invoice. Lambda stores the immutable source and identifies the workspace and CargoWise document key.
2

Prepare and reconcile

Lambda reads customer data, lines, taxes, totals, currency, dates, payment evidence, and the enabled PUE or PPD route.
3

Issue

Facturapi submits the prepared CFDI to SAT. The exact provider outcome is recorded.
4

Verify and deliver

Lambda verifies the returned UUID and fiscal values, stores XML and PDF, and starts Lambda outbound delivery.

​
Existing Government Number

If CargoWise already includes a valid Government Number, Lambda records Stamped externally and does not call Facturapi to create another CFDI. Lambda stores the UUID and source evidence so it can be used as parent evidence when a later payment or credit needs it. An external stamp is not a Lambda-owned provider record. Lambda cannot perform its normal cancellation or replacement flow for that CFDI.

​
CargoWise re-pushes

  • An exact duplicate delivery is idempotent and restores missing durable work when needed.
  • A delivery with different CargoWise data is normal new ingress with its own immutable capture. It never rewrites an older capture.
  • After issuance, Lambda keeps the issued CFDI and its fiscal snapshot unchanged.
CargoWise may not send a stamped income invoice back through eAdaptor after it writes GovernmentNumber. Do not use the absence of a later push as proof that Lambda did not stamp. See Files and delivery for artifact ownership and Recovery for safe retry behavior.
