Cross-field checks

Declare rules that run across fields after extraction — line items summing to a total, one date before another — and surface a mismatch as a finding.

Ovrin does not only validate fields independently. It also checks whether values agree with one another across a document.

Common examples

  • line items sum to the total
  • tax matches the subtotal and invoice total
  • values align with a known document pattern

Why this matters

Two fields may individually look plausible while still not making sense as a set. Cross-field checks catch contradictions that a single field validator would miss.
