Subscription — Semestral

$7,200 MXN + VAT, auto-renews. We need this for your invoice before sending you to the payment page.

Legal name and postal code must match your SAT tax certificate exactly, character for character. If they don't, the SAT rejects the CFDI 4.0 stamping — the charge still goes through, but no invoice is issued.

The subscription starts as soon as payment is confirmed — auto-renewals cannot be scheduled for later.

Each device gets its own credential: the first is full price, the 2nd and 3rd are 70%, and the 4th onward are 50%. The exact breakdown shows on the payment page before you confirm.

Where do I find this?

Your RFC is on your SAT tax status certificate ("constancia de situación fiscal").

Download it for free from the SAT portal with your password or e.firma. 13 characters for individuals, 12 for companies.

Where do I find this?

It is the full name exactly as it appears on your SAT tax certificate — include "S.A. de C.V." or another company suffix if your certificate has it.

Do not abbreviate or retype it differently: one comma, accent, or extra space is enough for the SAT to reject the stamping.

Where do I find this?

This is the postal code registered on your tax certificate, not necessarily where you currently live.

If it does not match your current address, use the one on the SAT document — that is the one that validates invoicing.

Where do I find this?

Also on your SAT tax certificate, under "Régimen".

If unsure, most independent surveyors are under 612 or 626 (RESICO); companies are usually under 601.

Charged by card. OXXO cannot fund recurring payments.
