PROCUREMENT INTERNAL CONTROLS
Put control before the books, not after the invoice.
A practical procurement control starts when the need is raised. Authority, supplier selection, receipt and invoice review are stronger when each decision is attributable to its source record.
Control questions
- Maker-checker separation
- Value-based approval routing
- Competitive sourcing or documented exception
- Supplier and award transparency
- Receipt and invoice exception review
Evidence to retain
- Named requester and approver
- Authority band and budget context
- Comparable supplier responses
- Award record and PO version
- GRN, invoice match and resolution note
