I need custom fields in expenses/bills for file number coz it's not proper to file bills/receipts per supplier. Is there a way to add custom fields in expenses/bills?

Adding a custom field to an expense or bill form isn't an option, ToughAura04.

You can use the Memo field for the file number on the expense and bill transaction.

Custom fields in QuickBooks online can be added only to all sales forms and purchase orders. Check out this link to learn how to create a custom field: How to add custom fields to sales forms and purchase orders.
