2. Match contract, purchase order, change order, rate card, milestone, and authorized buyer.
3. Confirm goods receipt, service evidence, dates, quantities, units, quality, and acceptance.
4. Recalculate subtotal, discount, expenses, tax, withholding, credit, prior payments, and total.
5. Identify split invoices, round-dollar anomalies, altered details, duplicate attachments, and unusual urgency.
6. Resolve exceptions with vendor and internal owner while preserving the original.
7. Route approval under segregation and authority limits.
8. Mark approved, disputed, partially approved, rejected, or paid with links to evidence.

## Done

- An invoice check record links vendor, contract, order, receipt, calculations, tax, exceptions, approvals, and status
- Duplicate, bank-detail, arithmetic, quantity, price, authority, and payment checks verify the obligation before release
