Key takeaways
- A sales order is a seller's document that records a confirmed order from a customer, with items, quantities, prices and delivery terms.
- It is the seller's mirror of the buyer's purchase order.
- It triggers picking, shipping and invoicing, so errors on it travel through the whole order.
- Match the sales order to the customer PO before you confirm.

What a sales order is
A sales order is the seller's internal record that a customer has placed a confirmed order, listing what will be supplied, at what price and when.
It starts life when a quote is accepted or a customer purchase order arrives. The sales team checks stock and credit, confirms the dates and releases it to the warehouse. The warehouse picks against it and the finance team invoices from it. If it is wrong, so is everything after it.
A customer sends PO 7712 for 500 units at 3.10 and asks for delivery by the 20th. The seller creates sales order SO-2210, checks stock for 500, finds only 420 and offers split delivery: 420 now and 80 on the 28th, which the customer accepts.
The sales order records two deliveries. The invoice follows each shipment, so the customer is billed for what it actually received.
