If you provide financing through a third party (bank, etc.) the third party will be charging a financing fee.  In order to document this using MO.S.T. you will need to have an account in QuickBooks under your Chart of Accounts.  If you need to add this to your QuickBooks and are unsure of the detailed steps, please contact your Bookkeeper, Accountant or Intuit (if you have support).  Below we give you a quick synopsis of where this is in QuickBooks so that you can look up an existing number or create it if you are comfortable creating an account in QuickBooks.
