# How Transitive works

> The path of a document from CargoWise to a CFDI, and back to CargoWise.

Transitive connects CargoWise to the SAT. CargoWise sends documents to Transitive. Transitive stamps the CFDIs through a stamping provider (PAC). Then Transitive sends the files back to CargoWise.

## The path of a document

<Steps>
  <Step title="CargoWise sends the document">
    CargoWise sends income invoices, payment receipts, credit notes and receipt reversals to
    Transitive. CargoWise can send a document again with new data.
  </Step>

  <Step title="Transitive examines the data">
    Transitive examines the data and the related documents. It decides if the document must get a
    CFDI. If a related document has no CFDI, the document waits.
  </Step>

  <Step title="Transitive stamps the CFDI">
    Transitive sends the document to the stamping provider. The provider stamps the CFDI, and the
    SAT records it. Each CFDI uses a stamp credit.
  </Step>

  <Step title="Transitive sends the files to CargoWise">
    Transitive keeps the XML and the PDF. In the live environment, Transitive sends the files back
    to CargoWise.
  </Step>
</Steps>

## What you see

* Each document has a status. The status tells you the condition of the document and what to do.
* Each document has a timeline. The timeline shows each step and each result.
* If a step fails, a failure code tells you the cause and the action to do.

## When you act

Usually, Transitive completes each step automatically. You act only when the status tells you to act. For example:

* Correct the data in CargoWise and send the document again.
* Stamp a document by hand.
* Cancel or replace a CFDI.
* Buy stamp credits or complete the company settings.
