I'm here to share information about your concern about importing invoices with custom fields in QuickBooks Online (QBO). I have checked our system, and it seems that the option you are trying to access is not available when importing invoices through the program. However, you can use a workaround by doing box mapping during the import process. After importing, you can manually add a custom field to achieve your goal.
Create custom fields.
You can have up to 12 active custom fields for each type of form (invoice, estimate, purchase order, expense, bill, and so on), and each type of profile (customer and vendor).Besides text, you can also create custom dropdown, date, and number fields.
Go toSettings, then select Custom fields.
SelectAdd Custom field. If you’ve already created a field, you’ll seeAdd fieldinstead.
Enter the name of the custom field in theNamefield.
Select the type of data in theData type▼ dropdown that will go in your custom field:Text and number,Number only,Date, orDropdown list. If you select the Dropdown list, enter the items in the list.
Select the category the custom field belongs to:Customer,Transaction,Vendor, orProject. Customer fields are for customer profiles, and vendor fields are for vendor profiles. You can assign transaction fields to sales forms (like invoices, estimates, and sales receipts) and purchase forms (like purchase orders, bills, expenses, and checks).
Select the forms where you want the custom field to appear.Note:To use custom fields in purchase orders, you need toturn on purchase orders for your companyfirst.
If you want customers or vendors to see the field on a form (such as invoices, estimates, or purchase orders), selectPrint on form. A maximum of 3 custom fields may havePrint on formturned on for any single form type (such as Sales Receipt or Invoice).
When you’re finished, selectSave.
Alternatively, you can use athird-party applicationto import invoices with custom fields seamlessly.
