About what the engine does, what it doesn't do, and why some things get flagged.
No. The engine automates verifiable documentary and tax work: extracts, validates, calculates and exports. Decisions on open cases, tax judgment or exceptional situations remain with the user or advisor. What it cannot resolve, it marks and escalates.
They are delivered in a separate list with the reason for flagging. The engine doesn't decide — it informs. The review and final decision are the user's. Nothing is hidden or automatically discarded.
No. It's designed for self-employed and ZZP'ers with low or medium tax complexity, without intensive cash operations. Retail, mass ticketing or complex labor cases fall outside the perimeter. The scope page details exactly what fits and what doesn't.
PDF, document images, documentary ZIPs and historical batches. Also via email, webhook, or direct form. The engine processes what it receives without prior reformatting.
The audit trail leaves a trace of each engine decision. If something is incorrect, it's reproducible and auditable. Furthermore, any document with ambiguity is flagged — the engine doesn't make definitive decisions on what isn't verifiable.
The engine uses exact arithmetic for all tax calculations, guaranteeing deterministic precision. The same input always produces the same output. The SHA-256 hash per document guarantees the result hasn't been modified.
The general ledger CSV output is compatible with leading Spanish and Dutch accounting software (A3, Sage, Wolters and equivalents). UBL 2.1 is the European standard for fiscal document exchange. The exact integration depends on each office's or software's workflow.
No. It manages the verifiable documentary and tax section: extraction, validation, calculation and export within the defined perimeter. Advanced accounting, the final accounting workflow and expert judgment remain the responsibility of the manager or user.
Yes. The sandbox lets you see the engine in action with example documents. If you're an agency or partner, you can request a private demo with a real batch before making any decision.
Yes. There's a separate B2B route with private demo, integration and white-label or hidden engine options. The entry point is the agencies page.
