# Introduction

> What Lambda is and how it fits next to CargoWise.

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 org-scoped Analytics reporting in Postgres for SQL and Power BI
* 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
