Intercompany Invoices are duplicated

Posted on by MP-26111204-0

In Business Central we have a problem that when we ship and post an Intercompany Sales Order from Company A, it is setup to automatically post the invoice on the Intercompany Purchase Order in company B.

The invoice is posted in Company B, however when looking in the purchase invoices that same invoice is created.

When we try to post it, it clearly shows that it is a duplicate.

Does anyone have an idea on why the invoice is duplicated? It is becoming a little messy as all intercompany invoices are duplicated and it is annoying to have to manually cancel the duplicated invoices.

This issue typically occurs when Intercompany Setup or Inbox Type settings are misconfigured, causing Business Central to both automatically post and create a purchase invoice document for the same transaction in the receiving company.

✅ Solution:

1. In Company B, go to Intercompany Setup.

2. Check if "Auto. Accept Transactions" and "Auto. Post Transactions" are both enabled.

3. If auto-posting is enabled, BC will post directly and not require a second manual posting.

4. If you're still receiving a purchase invoice, it means your Intercompany Inbox Type may be set to both “Journal” and “Purch. Doc.” — change it to "Journal" only to avoid duplicate document creation.

Also, check the IC Partner Setup for the sending company to make sure settings are aligned correctly.

Hi, Maybe it has something to do with the following settings.

Hi @MP-26111204-0 have you managed to solve this?

When an intercompany Sales Order is posted in Company A, it creates 2 IC transactions in the inbox of company B - one of type order and one of type invoice.

I have tried with both Auto-Send and Auto-Accept switched off - same result.

Thanks!

Hello ,

This is usually standard intercompany document behavior, not a real posting bug: Business Central can create the invoice in company B from the same IC transaction while the related intercompany purchase order is also still there, so you end up seeing a purchase invoice document that looks like a duplicate of the invoice already posted through the PO flow; Microsoft even notes that with Auto. Accept Transaction enabled, warnings about these duplicate purchase invoices can be suppressed, so the practical fix is to review your IC setup/process and make sure you use one invoice path only for the same transaction — either complete it through the intercompany purchase order lifecycle or handle the incoming IC purchase invoice, but not both.

Regards,
