In Fusebill, on the customer, navigate to the integration management settings.
Click the "Link" Button. If the Salesforce tab is not available, there may be an issue with your Salesforce configuration, or the main configuration has not been completed.
Once linked, Fusebill creates a bulk job to sync all the information on this customer to Salesforce. If this customer was previously linked, Fusebill will reuse existing IDs for entities such as the subscription, subscription products, purchases, and invoices where possible.
