Introduction - Packages
A package records what physically went into one box, before anything ships.
It is the bridge between an order and a shipment: the order says what was promised, the package says what is actually in the carton, and the shipment says where that carton went.

One order, several boxes
A sales order does not have to become one package. Splitting is the normal case rather than the exception: goods that arrive at different times, items too heavy to travel together, or a customer who wants the urgent half now.
- Packagethe box
- A set of lines from one source document, with quantities, packed together. It carries its own number.
- Shipmentthe journey
- What happened to that box: the carrier, the tracking number and the dates. This is what takes the stock off your count.
Not only for sales
The subtitle says it: packages cover sales orders, purchase orders and repairs. The Type and Source # columns tell you which document a box belongs to, so a return going back to a vendor is packed the same way a customer order is.

Why record it at all
The packing record is what makes a delivery dispute answerable. When a customer says two of the four arrived, the package says what was in each box and the shipment says which box the carrier lost.
- Every package belongs to exactly one source document.
- A line can be split across packages, but the total cannot exceed what the document promised.
- A package with no shipment against it has not gone anywhere.
- The packing slip prints from here, not from the order.
