Example Firm
Six things the SAT sees and you probably don't.
30 daysto correct
Supplier on the 69-B list
30 days is how long you have to correct before the SAT restricts your digital seal. Clauhub checks your suppliers every day.
CFF arts. 29-A fr. IX, 49 Bis and 17-H Bis
No XMLthe deduction is gone
Canceled invoice you already used
The SAT no longer hands out its XML and the deduction is gone. Clauhub detects cancellations every night.
Bulk download service v1.5
Day 5REP deadline
Payment without a complement
Day 5 is the supplier's deadline to issue the REP; without it you cannot credit the VAT. Clauhub lists your PPD invoices without REP and the VAT on hold.
RMF 2026 rule 2.7.1.32
Art. 69same alert as 69-B
Non-located supplier or firm tax debt
The SAT is already watching them before you pay them again. Clauhub flags them in the same alert as 69-B.
CFF art. 69

Invoice with the wrong tax regime
If it does not match your tax certificate, it must be reissued before month-end. Clauhub tells you which supplier to ask for a new one.

Frequently asked questions
How much does it cost per RFC or per user?
During launch, nothing: no monthly fee and no charge per user, and each plan says how many RFCs it includes. You only pay for stamps if you invoice, and you start with 6 on us. We never ask for a card, so nothing is charged on its own. If the price changes, we will let you know first.
Does it work for a firm with many clients?
Yes. Each client is a tax entity with its own RFC and e.firma, in the same account, with roles per person.
Can I give my client access?
Yes. Invite them with the Read-only or External auditor role. Inviting more people costs nothing today.
Can I bring what I already have in my downloader?
Yes. Drag in the XML you already have and Clauhub merges them with what it downloads from the SAT.
How long until I see my invoices?
Your most recent received invoices arrive within minutes. The issued ones and the five-year history take from a few hours to a day depending on your volume.
Do I need to install anything?
No. It works in the browser on any computer and on your phone.
What if the SAT portal is down?
It happens, especially around month-end. Clauhub retries on its own and tells you when the SAT is slow.
Does it replace the accountant?
No. It gives the accountant the XML, the Excel, the VAT working papers and the DIOT ready to review. The decisions are still theirs.
What happens to my data if I stop using it?
If you delete your e.firma, Clauhub stops downloading and your invoices stay. If you delete your organization, its invoices, XML and e.firma are erased. Before that you can download your XML in a ZIP.
