Merge Draft Invoices & Bills
Tick several draft customer invoices, or several draft vendor bills, of the same partner
and turn them into one document. A review window shows what will happen before anything
changes, sales and purchase order lines stay linked, and every merge leaves a record of
what was merged into what.
----------------------------------------
Key Features
✔ Merge from the list or from the document
Tick the drafts and choose Merge, or press Merge Drafts on a draft that has siblings.
✔ Review before anything changes
Documents, amounts, lines before and after, and what happens to each document.
✔ Clear reasons instead of a dead end
Every document that cannot be merged is listed with its reason and can be left out.
✔ New document or an existing one
Create a new draft, or add the lines to the main document you choose.
✔ Three ways to arrange the lines
Keep every line, add a section per source document, or add up identical lines.
✔ Order links stay intact
Sales order lines and purchase order lines remain linked; invoiced quantities stay right.
✔ Merge records
Number, user, date, choices, totals before and after and the list of source documents.
✔ No double invoicing
A merged source cannot be reset to draft while the merged document is alive.

Benefits
- One invoice for the customer instead of several, even when the drafts already exist
- One bill for several documents received from the same vendor
- Auditors see who merged what, when, and with which amounts
- Posted documents are never touched; totals are checked and the merge is rolled back on any gap
----------------------------------------
Ideal For
- Companies that invoice per delivery or per order and send one invoice per period
- Accounts payable teams that receive several bills for one vendor
- Accountants who need a clean audit trail for every consolidation
----------------------------------------
Technical Highlights
- Lines are copied with the standard Odoo copy routine, business links included
- Sources are cancelled with the standard routine, or deleted when never numbered
- Depends on the Invoicing app only; works with Sales and Purchase when they are installed
- Own access right, per-company settings, multi-company record rules, fully translatable
