How Lino Così generates invoices¶

In Lino Così every delivered item will get invoiced.

General functionality for automatically generating invoices is documented in invoicing : Generating invoices.

Side note: Code snippets (lines starting with >>>) in this document get tested as part of our development workflow. The following initialization snippet tells you which demo project is being used in this document.

>>> from lino import startup
>>> startup('lino_book.projects.cosi5.settings')
>>> from lino.api.doctest import *

Overview ¶

The invoice generator is is sales.InvoiceItem

>>> rt.models_by_base(rt.models.invoicing.InvoiceGenerator)
[<class 'lino_xl.lib.trading.models.InvoiceItem'>]

We must explain to Lino how a delivery note turns into an invoice by extending the models so that they inherit from InvoiceGenerator.
