What a purchase order fixes
A purchase order (أمر شراء) is the buyer's side of the bargain in writing: these items, this quantity, this price, delivered here by this date. Once the supplier acknowledges it, both sides have the same paper to argue from. It is not a tax document; the supplier's tax invoice, which must quote the order number, is where VAT lives.
- An order number and date, and the delivery date and address.
- Your details, including the VAT number the supplier will put on the invoice, and the supplier's.
- Lines with description, quantity, unit price, taxable amount, VAT at 15 percent and total, so the invoice can be checked against it.
- Who prepared and who approved the order, and a line for the supplier's acknowledgement.
The three-way match
A bill is paid when three papers agree: the order (what was agreed), the delivery note (what arrived) and the supplier's tax invoice (what is charged). A line that is on the invoice but not on the order, or invoiced at a higher price, or invoiced before it arrived, is held. The order is the first of the three and the one you control; the sample orders ten shelving units and two pallet jacks for a warehouse.
