These error messages can be avoided by editing your Sales settings in QBO. The error messages would contain:

  • "Not Able To Update Preferences", or

  • “...Discount Line Is Missing”

To set things right, follow these steps:

  1. Click the Settings icon in the top-right corner of your QuickBooks screen

  2. Under Account and Settings > Sales > Sales Form Content, find the off/on switches.

  3. Make sure “Custom fields”, “Discount”, and “Deposit” are set to "On".

  4. Click Save.

​​A more complete view of the Account and Settings page for the Sales section will now look like this:

Now you will be able to update invoices that have already had payments assigned to them or those that have overall order discounts!
