Process your documents.
Verify. Calculate. Export.
Deterministic tax and document engine for freelancers and ZZP. Extracts what is in the document, validates what can be validated, flags what is doubtful. The final decision is always yours.
No account. No real data. To see the engine in action.
What the engine does
The same input always produces the same output. No free interpretation. No black box.
Extraction and validation
Extracts tax data from PDFs, images and ZIPs. Validates NIF/VAT against VIES. Calculates with BCMath. Every step leaves a trace.
Four states, not two
Accepted, accepted with rule, flagged, escalated. What is doubtful doesn't disappear — it is separated and explained. You decide what to do with it.
Verifiable export
JSON with full audit trail, CSV grootboek, UBL 2.1, ZIP with originals. SHA-256 per document. Reproducible from the same input.
