The companies that export Invoices created in Energy Force to Agvance often have their customers set up for CRM so that their Invoices are emailed to the customers when generated in Agvance.
The emails will only send out automatically without additional steps if the Mail Host information as well as the API Database ID at Hub / Setup / Company Preferences are populated and include accurate information.
If the Mail Host information and/or API Database ID are not populated, go to Accounting / A/R / Batch Print Invoices, indicate preferences to apply to the imported Invoices, and be sure the Email Invoice(s) option is checked. This will disable the Printer drop-down as it will not print these documents but email them through CRM. Select OK.
