eInvoicing: Unable to connect to IAM after UBS Accounting & Inventory version 2026.1 update

IAM Grey, Cannot restart IAM services, Failed to restart IAM Client Service.

If IAM appears grey or you can’t restart IAM services after you update UBS Accounting & Inventory to version 2026.1, you can fix the connection by copying three files into the Tools folder of UBS BSM and/or UBS POS.

⚠️Important: This solution is only valid if you’ve just upgraded to UBS Accounting & Inventory version 2026.1 (13 October 2026), and you have UBS BSM and/or UBS POS installed on the same machine as UBS Accounting & Inventory.

Copy and paste the required files

Copy three files from UBS Accounting & Inventory, then paste them into the Tools folder of UBS BSM and/or UBS POS.

  3. Copy the following files:

  4. Paste the copied files into the Tools folder of UBS BSM and/or UBS POS as applicable.

    • If both UBS BSM and UBS POS are installed, paste the files into both locations.

  5. Once completed, launch UBS AIB and open the Inventory & Billing module.
