Lambda is Jaantonio’s product for Mexican fiscal compliance on top of CargoWise. CargoWise remains the source of accounting truth — amounts, match lines, FX, and transaction fields. Lambda turns those documents into stamped CFDIs through Facturapi, stores the SAT evidence, and (when configured) returns artifacts to CargoWise.

​
What Lambda does

  • Accepts accounting documents from CargoWise over Lambda ingress
  • Validates and reconciles fiscal data before any stamp attempt
  • Issues CFDIs through Facturapi and stores the SAT UUID and artifacts
  • Delivers stamped XML/PDF back to CargoWise over Lambda outbound
  • Keeps an org-scoped reporting database for Analytics
  • Surfaces clear workspace statuses when a document is waiting, failed, or needs support

​
What Lambda does not do

  • Replace CargoWise as the accounting system of record
  • Invent missing fiscal values, FX, or parent evidence
  • Stamp when data is contradictory — it pauses and explains instead
