Frequently asked questions

How much does it cost?

VAT Refund costs $899 per month for the first RFC and $299 per month for each additional RFC, plus VAT. It includes everything in the Pro plan: full validator, API and batches, SAT downloads, PDFs and the EFOS check and monitor. Calculating and exporting the refund for an RFC needs an active seat; you can see the example Excel, the manual and the guide first, with no sign-up. You can pay by card on Stripe (several RFCs) or with Mercado Pago (one RFC).

Does ALCE Fiscal guarantee SAT will approve my refund?

No. ALCE Fiscal does not guarantee approval. It helps detect errors, organize CFDIs and prepare information for review before filing.

Does the tool replace my accountant?

No. The tool supports analysis and CFDI organization, but tax decisions should be reviewed with your accountant or advisor.

What do I need to get started?

The CFDI XML files for the period you want to review. With your e.firma, ALCE Fiscal downloads them from SAT for you; if you don't have it handy, you can upload the XML files manually. Depending on the case, your accountant may require additional information.

Does it detect cancelled CFDIs?

Yes, the tool identifies cancelled CFDIs or alert statuses so they are not included without review.

Does it review EFOS/EDOS supplier risk?

Yes, it flags suppliers with possible EFOS/EDOS risk for review before integrating the request.

What are VAT refund working papers?

They are reports and supporting files that help document included CFDIs, excluded CFDIs, creditable VAT, detected alerts and reviewed evidence before filing the request.

Does it generate the dossier automatically?

It generates reports and organized files as a documentary base. Final filing should be reviewed according to each taxpayer's fiscal case.

Does it work for individuals and companies?

Yes, as long as they have CFDI XML files and need to review information related to creditable VAT and supporting documentation.

ALCE Fiscal does not replace your accountant's professional judgment. The tool helps detect inconsistencies, organize evidence, and reduce errors before filing a VAT refund request with SAT.

Review your VAT refund before filing

Detect CFDIs with errors, estimate your creditable VAT and generate reports to review your dossier with more clarity.
