Sales order invoicing by percentage of the quantity
This module allows to invoice a percentage of the sales order, modifying invoiced quantities according such percentage.
Example: You have a service line to invoice 10 hours. You choose to invoice a 50% of the quantity, so the generated invoice line has 5 hours.
auto_awesome What this module does
AI-generated from the code · Odoo 19.0Lets you create a customer invoice for only a percentage of the ordered quantity from a sales order. You pick "Percentage of the quantity" in the invoice wizard and enter the percentage, and the invoice lines are reduced accordingly.
When you invoice a sales order, the standard wizard now offers an extra option called "Percentage of the quantity" next to the usual invoicing methods. Choosing it reveals a new field where you type the percentage you want to invoice, for example 50.
- The invoice is then created for that share of the ordered quantity: a line of 10 hours invoiced at 50% becomes 5 hours on the invoice.
- The percentage applies to the quantities of the sales order lines being invoiced; prices and other line details stay as they are.
- After the invoice is generated, the wizard switches back to the normal invoicing method, so the rest of the order can be invoiced later in the usual way.
The change appears in the invoice creation wizard opened from a sales order, in the section where the invoicing method is chosen. It touches the sales order line preparation and the advance payment invoice wizard (sale.advance.payment.inv). No new menus or reports are added.
