A5 Fax is the first Salesforce App to integrate eFax, the most popular electronic fax solution with Salesforce to provide you basic sending and receiving of faxes from inside Salesforce to complete automation to send documents and receive them using barcode identification feature. The app could take as little as 30 minutes to get up and running. You will pay a monthly fee for the app as well as a cost per fax page if you go over the limit. You will get a dedicated fax number that is local or toll free and you can purchase additional fax numbers if needed. You don’t need an existing eFax account.
