Frequently asked questions

What is a purchase order?

A purchase order is a buyer’s formal offer to purchase: it lists what is being ordered, at what agreed prices, and by when it should be delivered. Once the supplier accepts it, it becomes the commercial reference both sides work against — the supplier quotes its number on the invoice and delivery documents.

What is the difference between a purchase order and an invoice?

They travel in opposite directions. The BUYER issues the purchase order before delivery; the SUPPLIER issues the invoice after delivery, referencing the PO. Matching the two (and the delivery note) before paying is the classic three-way check that stops wrong or duplicate payments.

Why should a small business bother with POs?

A PO turns verbal orders into a written record: agreed prices cannot drift, deliveries can be checked against what was ordered, and month-end reconciliation becomes matching documents instead of memories. It also signals to suppliers that your purchasing is organised.

Should purchase orders have their own number series?

Yes. A PO series (PO-0001 onwards) separate from your invoice numbering keeps both audit trails clean. This tool maintains a dedicated PO counter per business profile, alongside your invoice, estimate, proforma and receipt series.

Is a purchase order legally binding?

Generally, an accepted purchase order forms a contract: the buyer offers, the supplier accepts by confirming or delivering. Until acceptance it is an offer that can be withdrawn. Put your terms — delivery, payment, cancellation — in the terms section so they are part of the offer.
