Shipment
A shipment records stock physically going out to a customer. It is separate from the sales invoice, which records the money side.

Why they are separate
Section titled “Why they are separate”Goods and paperwork do not always move together. Shipping first and invoicing later — or the reverse — is normal, and keeping the two documents distinct means stock and receivables each reflect reality at the time they happened.

Creating a shipment
Section titled “Creating a shipment”Pick the customer and add the items and quantities leaving, from which location. Submitting reduces stock on hand and posts the cost of goods sold.
From an invoice
Section titled “From an invoice”A shipment can be created from a submitted sales invoice, which pre-fills the customer and lines. Where inventory is enabled, this is the usual flow.
