Invoice validation
Illustrative preview · CFDI 4.0
Evidence per invoice
Illustrative example: each report distinguishes what passed, what failed and what remains unverified. This is not SAT certification.

The ViciousByte ecosystem
Organize your work across three families. Use each product for its purpose and combine your own references where supported, with reviewable results and access scoped to your account.
Family 1
Issue CFDI 4.0 and validate invoices in batches. Each product keeps its specific fiscal scope.
Family 2
Investigate open sources with OSINT tools. Bounded results, not universal proof of security.
Family 3
Turn audio and video into text, with result exports.
A common language of sources, evidence and review. Each step stays within the selected product's scope.
Import supported formats, such as CFDI invoices or audio files.
Run bounded validations, searches or transcriptions. Product limits, quotas and provider conditions remain in force.
Inspect provenance and unknown states. Human review remains where the product requires it.
Export in supported formats and consult history within its retention period.
Sharing a family does not grant access to other products or activate automatic integrations. Connections use explicit, authorized references.
