Until SEFAZ starts rejecting
Deterministic. Cited. Auditable.
No “probably.” The engine applies the rules published in the Technical Notes, versioned by effective date — and shows where every verdict comes from.

Send your invoices
A sample of Brazilian NF-e/NFS-e (XML). No account needed to start; files expire in 7 days and the recipient is never stored in clear text (Brazilian LGPD).

The engine checks rule by rule
Structural validation (official XSD) + IBS/CBS content rules versioned by effective date — the same rules SEFAZ applies on 2026-08-01. Deterministic: no verdict is born from AI.

What changes on August 1
What happens on August 1, 2026?
SEFAZ moves the IBS/CBS validations from warning to rejection for NF-e and NFC-e (NT 2025.002 and NT 009). Invoices missing the new IBS/CBS groups are not authorized — and the operation stops.
Why does this matter to a foreign company?
If you operate in Brazil or buy from Brazilian suppliers, rejected invoices halt shipments, receivables, and tax credits. The assessment tells you — per document and per supplier — what will be rejected, before it happens.
How is the verdict produced?
By a deterministic rules engine versioned by effective date — never by generative AI. Every finding cites the Technical Note or law (LC 214/2025) behind it.
What do we need to provide?
A sample of your Brazilian e-invoices (XML). Files are deleted after 7 days and the recipient is never stored in clear text (Brazilian LGPD).
What do you deliver?
A readiness score (0–100) and a findings report in English, each finding with the cited rule, plus a review call. The Complete tier adds a supplier-readiness map and 90 days of monitoring.
