AI-generated from the code · Odoo 19.0

Lets you select several draft invoices in the invoices list and combine them into a single invoice, as long as they share the same partner, type, currency, journal and other key details.

This module adds a "Merge Partner Invoice" action to the list view of invoices (account.move). Select two or more draft invoices and run the action to open a small confirmation window.

  • The window explains the merge rules and offers two options: keep the references from the original invoices, and set a specific invoice date for the merged invoice.
  • If the selected invoices cannot be merged, the window shows an error message instead of the merge button, listing what differs (for example state, partner, currency, journal, company, salesman, bank account or invoice type).
  • Only invoices in draft state are merged. Invoices are grouped by partner, user, type, currency, journal, company and partner bank account.
  • Invoice lines are combined when they are identical except for quantity; quantities are added together. Empty lines can be dropped.
  • Original invoices are cancelled after the new merged invoice is created, and links from sale or purchase order lines are moved to the new invoice lines.
  • After merging, Odoo returns to the invoice list filtered on the original and new invoices.
