Odoo 18 Enterprise – Inter-Company Transaction Synchronization: Returns Not Syncing

Question

Hello,
I am using *Odoo 18 Enterprise* with *Inter-Company Transactions* enabled. The standard sales → purchase synchronization is working correctly between Company A and Company B.
However, I noticed that *returns are not synchronized*.
Example:
Company A creates a return for a customer (credit note / return picking).
This return *does not generate any corresponding return* (refund / return picking) in Company B.
*My questions:*
Why are *returns not synchronized* in Inter-Company Transactions?

Hi,

Odoo's standard Inter-Company
Transactions (ICT) doesn't automatically synchronize returns due to
financial, approval, and inventory complexities. To achieve this, you
can either develop a custom module to automate return creation, use
Odoo's automation rules for manual synchronization with notifications,
or explore third-party apps in the Odoo App Store.
Custom
development offers the most flexibility but requires significant effort,
while manual synchronization reduces risks but needs some

Hello  ZAMEEL ISMAIL
I hope you are doing well
*Answer:*   Returns are *not * *synchronized by design* in Odoo 18 Inter-Company Transactions. The module only handles forward flows (SO→PO, Deliveries→Receipts), not reverse operations.  *For accounting refunds: * Enable *"Generate Bills and Refunds"* in Settings → Inter-Company Transactions — this syncs credit notes (out_refund → in_refund) automatically.  *For stock-level returns:* No built-in solution. You need a custom module to override stock.
