Approved purchase order and changes, dated goods receipt, invoice lines, item units, currency, company tolerances and review owner.
Workflow
- Select two-way or three-way review according to the company policy. Three-way review includes receipt evidence; do not assume a receipt exists.
- Match line identity, unit and currency before comparing quantity and price. Keep partial receipts separate from full delivery.
- Apply only the supplied approved tolerances; an unspecified tolerance is unknown. Flag quantity or price differences for review rather than silently accepting them.
- Return an exception register and source links. Do not approve payment, edit a purchase order, create a receipt or contact the supplier.
Output contract
line | PO quantity/price | received quantity | invoiced quantity/price | discrepancy | policy tolerance | evidence | review status
Fictional acceptance test
Fictional PO authorizes 10 units at $12 each; receipt records 8 units; invoice bills 10 units at $12. Under the supplied zero quantity tolerance, $24 of invoiced quantity lacks receipt evidence. Mark two units for review; do not reduce or pay the invoice automatically.
Review gates and limits
Verify 10-8=2 and 2*12=24. If the unit on the invoice is cartons rather than units, comparisons stay blocked pending conversion evidence.
