From order to delivery

Need a formal request before the purchase order itself, so someone internally can approve the spend? Start with the Purchase Requisition Generator. When goods ship, match delivery against the order with the Packing Slip Generator. The supplier then bills against this order with the Invoice Generator.

Frequently asked questions

When does a business issue a purchase order?

A buyer issues a purchase order to formally authorize a purchase before the supplier ships goods or performs work — it locks in the item, quantity, price, and delivery terms up front. Businesses that receive a purchase order (as a supplier) use it to confirm what was agreed before starting the order.

How does a purchase order relate to the supplier’s invoice?

The purchase order comes first and states what the buyer is authorizing; the supplier’s invoice comes after delivery and requests payment for it. Matching the invoice against the original purchase order (a "three-way match" with the packing slip) is a standard accounts-payable control to catch pricing or quantity discrepancies before paying.
