Customers
Companies in Manage are mapped to Customers in Sage 50. The "Account" field on the Manage Finance > Company Finance screen needs to match the "Customer ID" field on the Maintain > Customers/Prospects screen in Sage 50. If a Customer in Manage has an invoice to be imported into Sage 50 and the customer does not exist in Sage 50, a new Customer will be created in Sage 50 automatically.
