Invoice lines

Proforma invoice lines always point at a contract line: you do not invoice a loose product, you invoice goods received under a contract.

Adding lines

Add line opens the available lines dialog: the Contract lines with available quantity (received minus committed) that are not yet on this invoice. For each one you see the SKU, description, received, committed and available. Tick the ones you want, adjust the quantity and confirm.

You can also paste from a spreadsheet (product code, quantity, price; Ctrl+V on the table) or import an Excel with Data > Import lines. Either way the SKU must exist on the contract and the quantity cannot exceed what is available.

Editing

In draft, quantity and price are edited right in the row. The quantity cannot exceed its contract line's available amount or be zero; trying more is refused with the reason.

The pencil opens the edit dialog, the arrows reorder and the X removes the line (which returns the quantity to the contract's available amount).

After release

The lines are frozen and the Shipped column appears, filled by the Shipments.
