Sale Product Line Position Customization

Automatic sequential position numbers on quotations, sales orders, and invoices.

Developed by 2BIT Digital GmbH — your Swiss Odoo partner for payroll, accounting, eCommerce, manufacturing and custom business solutions.

Overview

This module automatically assigns sequential position numbers to sale order lines and carries them through to the invoice. The numbers appear in a dedicated Line Number column both in the Odoo form view and in the printed PDF documents.

Position numbers are recomputed automatically whenever lines are added, removed, or reordered. A Lock Positions option is available to freeze the numbering when needed.

Business Impact

Why You Need This Module

Customers and internal teams often refer to specific lines on quotations and invoices by position number. Without explicit numbering, references like “line 3” are ambiguous — especially when documents have many lines or are revised.

Which Problems It Solves

• No visible line numbers on printed quotations and invoices
• Inconsistent line references between sales orders and invoices
• Manual numbering that gets out of sync when lines are reordered

Key Benefits For Sales And Billing Teams

• Sequential position numbers maintained automatically on all sale order lines
• Line Number column visible in the Odoo form view and on printed PDFs
• Invoice line numbers match the originating sale order line numbers
• Lock option to freeze numbering when the order is finalised

How It Works

• Create a quotation and add product lines — position numbers are assigned automatically starting from 1.
• Numbers are updated automatically when lines are added, removed, or reordered.
• The Line Number column appears in the order line list and on the printed quotation and order PDF.
• When an invoice is created from the sale order, the line numbers are carried over to the invoice and printed on the invoice PDF.
