You can include the terms of payment in the description column, Michael.
Currently, QuickBooks Self-Employed (QBSE) doesn’t have the option to modify the terms of payment. This functionality is available in QuickBooks Online (QBO). Could you let us know which specific invoice details you’d like to update? Please note that in QBSE, you can only edit information that is already included on the invoice.

Feel free to reach out if you have any other questions about payment terms or managing your invoices.
