What to enter

Make the match explicit.

Enter the approved terms and invoice lines yourself. Invoice lines reference an approved line ID. Repeated invoice lines use the same approved ID so the allowed quantity is checked across their combined quantity.

Decimal values stay as text: quantity up to six decimal places, rate up to six, and billed amount up to two. Do not use currency symbols, commas, or exponent notation.

Scope

A review aid for a narrow case.

This prototype covers fixed USD rates and simple multiplication. Taxes, credits, discounts, tiered rates, minimums, proration, foreign currency and other adjustments require a different review. Mark unsupported adjustments or incomplete line lists and totals will be withheld.

Outputs describe entered evidence and modeled differences. They are not a payment instruction, a legal conclusion, a refund entitlement, or achieved savings.
