This article explains why you may see the error “already connected by someone else” when restoring Sage 50 company data from a backup, and how to resolve it so you can use connected services like Satago.
You are likely seeing this error because your Sage 50 company was created using a database backup from another company (often by a consultant or accountant). This method is not recommended by Sage.
The backup contains a unique identifier (the Company Ref) that is already in use by another company. This duplication prevents you from using Sage’s connected services, including Satago.
Create a new company file in Sage 50 and copy your data following Sage’s official guide: How to create a new company from an existing company.
If you need help with the data migration process, contact Sage Support and explain that you have a “Duplicate CompanyRef” issue. Let them know you have been advised to create a new company in Sage 50 and transfer your records over, starting with opening balances.
Sage Support can guide you through the process and ensure your company is set up correctly.
