Expense and receipt validation

An expense may be business-related while the document is insufficient for input-VAT recovery. Accounting acceptance, income-tax treatment, VAT deduction and evidence should therefore be assessed separately.

01

What to verify

  • Original document and contractual supply context

  • Tax point, amounts, currency and corrections

  • Approval, export, retention and audit trail

02

Practical workflow

  1. 1

    Capture the decisive facts and select the correct jurisdiction and date.

  2. 2

    Resolve the time-valid rule and record its source, version and open questions.

  3. 3

    Align invoice, accounting, reporting and evidence; route uncertainty to review.

03

Worked example

A meal receipt supports a business expense but lacks data needed for the intended VAT deduction. Dynafis returns separate findings rather than one binary score.

Common mistakes

  • !

    Automation without idempotency and audit evidence

  • !

    Correcting only the PDF but not the canonical data

  • !

    Treating uncertain extraction as approved tax data

05

Invoice and accounting impact

The result should be represented consistently in the invoice, structured data, accounting, reporting and evidence. If a decisive fact changes, the decision is recalculated and the previous version remains in the audit trail.
