Document Validation

Extraction tells you what the numbers are. This tells you whether they agree with each other.

Four checks, no guessing

Plain arithmetic over the extracted tables. No language model touches the numbers.

Column totals

Item rows add up to the Total or Subtotal row beneath them.

Row totals

Q1 to Q4 style columns add up to the Total column at the end of the row.

Cross-section

A section total on page 2 matches the same figure restated in the page 5 summary.

Derived values

Quantity times unit price equals the line amount. Subtotal plus tax minus discount equals the grand total.
