Preserving Evidence in Revised Purchase Order Deliveries
Review Question and Source Records for Preserving Evidence
When evaluating revised purchase order deliveries, the central review question is: Are the updated purchase orders, delivery notes, and supplier invoices consistent in terms of quantities and approved prices?
Key source records to collect and compare include:
- Updated Purchase Orders: Documents that reflect changes or amendments to original order quantities and pricing.
- Delivery Notes: Records accompanying shipments that specify delivered quantities.
- Supplier Invoices: Bills submitted for payment, detailing quantities and prices invoiced.
Reviewers verify if these records align and identify any missing authorizations for revisions. Discrepancies must be noted and unresolved exceptions documented for follow-up. Archiving both original and revised documents is essential to maintain a clear audit trail.
Collecting, Comparing, and Reviewing Source Records
Begin by collecting the original and revised purchase orders, associated delivery notes, and supplier invoices relevant to each order revision. Then:
- Compare updated purchase orders with corresponding delivery notes to confirm that delivered quantities align with the revised order specifications.
- Verify that supplier invoices reflect the approved prices as stated in the updated purchase orders for each line item.
- Document any missing authorizations or discrepancies such as deliveries without corresponding order revisions or invoices priced differently than approved.
The reviewer’s role is to identify unresolved discrepancies requiring further inquiry or approvals; note that this review confirms evidence consistency but does not guarantee all differences are fully explained or resolved. Archiving all original and updated source documents ensures a reliable audit trail for future reference.
Illustrative Example of Reviewing Revised Purchase Order Deliveries
Consider a transport company that received an updated purchase order indicating a change in the quantity of pallets to be delivered. The reviewer compares the revised purchase order with the delivery note and the supplier invoice for the same shipment. The delivery note confirms receipt of the adjusted pallet count, but the supplier invoice reflects the original higher quantity at approved prices. The reviewer documents this discrepancy and seeks authorization or explanations for the invoice amount exceeding the updated order. Without such authorization, this exception remains unresolved. The original and revised purchase orders, delivery notes, and invoices are organized and archived, creating an audit trail for further investigation or dispute resolution. This process supports transparency but does not automatically resolve every discrepancy found.
Completion Checklist and Review Report
- Verify that updated purchase orders, delivery notes, and supplier invoices for each transaction have been compared and reconciled.
- Confirm quantities and approved prices match across the source records or note discrepancies.
- Document any missing authorizations or incomplete support for revised purchase orders.
- Archive the original and revised purchase orders, delivery notes, and invoices with clear labeling for audit traceability.
- Prepare a review report summarizing supported conclusions and explicitly identifying any unresolved exceptions.
- Assign the review owner who conducted the comparison and clearly indicate the next reviewer’s responsibility to follow up on open items.
- Emphasize that the report reflects evidence examined and does not confirm all discrepancies are resolved.
