# Link Account The GUMU™ is a real-time bi-directional integration, using the GUMU™ you can import new customers from Sage to Salesforce. But what if a customer already exists in Salesforce? You will have to link the existing Customer before bringing the Customer from Sage to Salesforce to avoid duplication. The GUMU™ Link Account feature helps you do this. Once the Salesforce Accounts gets linked with Sage 100 Customers, you can see real-time inquiries (Customer Details, Sales Orders, Invoices, etc.) in Salesforce. You can also create Sales Orders for that linked account and promote them to Sage 100. To link Salesforce Accounts with Sage 100 Customers follow the steps below: 1. Navigate to the **GUMU™ Settings** app and then click on the **Link Account** tab.
2. To find a particular account you can search in the **From Account Name** and **To Account Name** fields.
3. Click the **Get List** button and the list of linked Accounts/Customers will be populated in the grid. 4. Click the **Auto Match** button to automatically match the Salesforce accounts with the selected Integration (matched Sage customers will be populated in the grid under the ERP Customer column).
