Purchase order: what it is, what it includes and how it differs from a sales order
For the wholesaler a chain tells "no purchase order, no payment" and for the store that wants to order in writing and have the price honored. What a purchase order exactly is, where it fits between the quote and the invoice, what it has to say and a free template to build one in two minutes.
A purchase order is the document a buyer uses to formally request goods from a supplier: which items, how many, at what price and on what delivery and payment terms. The buyer issues it, it carries a number and a date, and once the supplier accepts it, it becomes a commitment for both sides: the buyer commits to receive and pay, the supplier to deliver what was ordered at the agreed price.
In a small wholesale purchase it is rarely seen: the order comes in on WhatsApp and that is it. It shows up when the buyer is a company with a purchasing process, a chain, a public body or anyone who needs control: there, the purchase order is the condition for the invoice to get paid.
From quote to invoice: where it fits
| Document | Issued by | What it says | Binds |
|---|---|---|---|
| Quote | The supplier | Price, validity and terms offered | No one, until accepted |
| Purchase order | The buyer | What is ordered, how much, at what price, how it is delivered and paid | Both parties once the supplier accepts it |
| Sales order | The supplier | The same as the purchase order, recorded on the seller's side | The buyer when they sign it in approval |
| Packing slip | The supplier | Which goods travel and who received them | Proves delivery; not a tax document |
| Invoice | The supplier | The sale, with taxes, referencing the purchase order | Tax document; it is what gets paid |
What a purchase order includes
- Number and date. The number is what the supplier will cite on the packing slip and the invoice; without it, the chain does not pay.
- Buyer and supplier. Company name, tax ID, address, and whom it is addressed to.
- Line items. Code, description, quantity, unit (unit, case, bulk), agreed unit price and amount per line. The code must be the supplier's, or both.
- Total and tax condition. Whether prices are before tax or final; with a prior quote, copy it from there.
- Delivery. Place, lead time or date, receiving hours and who pays the freight.
- Payment. Agreed method and term: net 30 by bank transfer, on account, cash on delivery.
- Authorization and acceptance. Signature of whoever authorizes the purchase and, when it comes back, the supplier's acceptance.
The purchase order generator builds the document with all this data and downloads it as a PDF, no sign-up. To work it in Excel, the sales order spreadsheet.
Why large buyers require it, and what it means for the wholesaler
In a company with a purchasing process, nobody pays an invoice that does not match an authorized order: it is the control that separates whoever orders from whoever pays. For the supplier that has three consequences. The invoice must cite the order number, with the same quantities and prices. Goods not on the order do not get paid, even if delivered. And a price change after the order is discussed before delivery, not on the invoice. With a numbered quote and a written validity, the order goes out with the right data and the invoice gets paid without back and forth.
How VentasxMayor solves it
- The portal order serves as the purchase order. The store logs in, sees its price list and its minimum, and places the order: it is numbered and at the agreed prices, with nobody copying it from a PDF.
- The notes keep the buyer's reference. If the company needs its own order number on the invoice, it writes it in the order notes and it travels with the order to the ERP.
- Packing slip and invoice come out of that same order. With the ERP integration, the order lands with buyer, items and terms, and the invoice is issued there referencing it.
