# 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 it from Sage to Salesforce to avoid duplication. The GUMU™ **Link Account** feature helps you do this.
