CFDI Guard: evidence per invoice
Distinguish verified checks, failed checks and evidence that remains unverified.
Three distinct layers of evidence
XML structure
Reviews the structural rules applied to a document and preserves their results. Correct structure alone does not prove fiscal authenticity.
Issuer signature
Checks the signature, original string and attached certificate key when compatible material is available. Certificate trust and revocation are shown separately as unverified.
SAT status query
When enabled, preserves the query response and its date. An unavailable provider or unverifiable response is not converted into a valid result.
Current service configuration
An enabled capability indicates available configuration, not granted account access or a successful result for every query. A ViciousByte evidence signature attests to application evidence integrity; it is not a SAT stamp.

Privacy and retention
Projects belong to one account. Original XML is kept in private storage together with JSON evidence; reads and downloads require authorization. No invoice upload is needed to request access.
Each batch shows its effective expiry date in the dashboard. Expiry or a deletion request blocks access and queues XML, evidence and payload purging; physical deletion is asynchronous. A separate minimal idempotency and quota receipt retains no XML, RFC or text.
The server confirms account and project access through a compatible current validation plan, an explicit pilot grant or a paid CFDI Guard period. Purchasing CFDI Guard does not replenish the legacy invoice validator. A pending request grants no permissions and starts no payment.
Plans and additional units
