Problem
Required parameter ExpenseAccountRef or IncomeAccountRef is missing in the request.
Resolution
QuickBooks requires that items have at least an income account or expense account. BMS does not have those fields required. Hence if you leave those fields empty in BMS and no Default options are supplied you will get this error.
- Go to BMS
- QuickBooks Setup Page
- Either Setup the Default Income or Expense Accounts there
- Or go to the item having this issue itself
- And set the Income and expense account there.
