Atlas

Tax intelligence for Mexico

Everything the SAT knows about you, reconciled.

Atlas pulls CFDI, tax returns and the SAT compliance opinion (opinión de cumplimiento) directly from the SAT, reconciles them and flags risk before it becomes a penalty or a bad loan. For your own RFCs or your clients'.

Who it is for

The same tax data, two different decisions.

Companies and accounting firms

Stay compliant, without surprises.

Reconcile what you invoiced, what you were invoiced and what you declared. Monitor your suppliers and your RFCs in one dashboard.

Financial institutions

Lend on data, not on bank statements.

With the applicant's authorization, Atlas reads their tax history and gives you real revenue, customer concentration and 69-B risk in minutes.

The problem

The tax data exists. Nobody has it in order.

Manual downloads

Someone logs into the SAT portal one RFC at a time, downloads XML files and builds spreadsheets that are stale the next day.

Gaps that show up late

Invoiced, declared and booked figures don't match, and you find out during the audit, in a SAT letter or after the loan is granted.

Invisible third-party risk

A supplier or an applicant lands on the 69-B list and almost nobody checks every month.

How it works

Three layers, one place.

    3

    Intelligence

    Monitors the 69-B list, EFOS and related parties, computes indicators and tells you what to review, why and by when.

    2

    Reconciliation

    Matches issued against received, CFDI against tax returns and payments against invoices. Every gap is identified by UUID, amount and period.

    1

    Extraction

    Connect the RFC with its CIEC or its e.firma, whichever you have at hand. Atlas downloads issued and received CFDI, tax returns, tax status certificate and compliance opinion from the SAT, and keeps them current.

SAT connection

With your CIEC or your e.firma. You get the same.

RFC and CIEC (SAT password)

Your RFC and the password you use to log into the SAT portal.

or

e.firma

Your .cer and .key files and their password.

With either one you get:

  • Issued and received CFDI with their status
  • Monthly and annual tax returns
  • Compliance opinion and tax status certificate
  • Electronic accounting
  • Automatic recurring sync

Credentials encrypted in a secrets vault. Atlas only reads: it never files, signs or changes anything with the SAT.
