Most procurement breakdowns happen at the PR-to-PO handoff — an approved requisition becomes an unapproved order because someone skipped the conversion controls.
Start here
- Purchase orders — how POs are created and managed
- Purchase requisition approval workflow — the upstream control
- Approval policies — the rules engine behind both
The handoff problem
A purchase requisition says “we need this.” A purchase order says “we are buying this from this vendor at this price.” The gap between the two is where scope creep, price inflation, and unauthorized vendor selection happen.
In Dubai operations — especially construction and contracting — PRs often get approved at one amount and converted to POs at a higher amount with a different vendor. If your system allows direct conversion without re-validation, you have a governance gap.
Controls that close the gap
- Lock the PR reference — every PO must carry its source PR number. No orphan POs.
- Validate amount tolerance — if the PO total exceeds the approved PR amount by more than your threshold (5–10% is common), require re-approval via your approval matrix.
- Enforce vendor match — if the PR specified a vendor (from an RFQ), the PO vendor must match. Vendor changes require justification and a separate approval.
- Prevent partial cherry-picking — if a PR has 10 line items and the PO only covers 3, flag the remaining 7 as unconverted. Track them.
- Block double-conversion — a PR line item that has already been converted to a PO line cannot be converted again. Use idempotency controls.
What the audit trail should show
For every PO created from a PR, your audit logs should record:
- Source PR reference and approval status at conversion time
- Any line-item quantity or price differences between PR and PO
- Who performed the conversion and when
- Whether the conversion triggered a re-approval
Operationalize it
Add PR-to-PO conversion status to your weekly procurement review. Use report builder to surface PRs that were approved more than 7 days ago but have not been converted. These are either stale or stuck — both need attention.
The goal is not to slow procurement down. The goal is to make sure an approved request actually becomes an approved order — with evidence.
