Hi chhinkun,

I'm here to help.

You can edit the invoice template to add columns.

Here's how:

1. Click Lists.
2. Select Item List.
3. Select the invoice template.
4. Right click and select Edit Template. The Basic Customization window will open.
5. Click the Additional Customization button. The Additional Customization window will open.
6. Go to the Columns section.
7. Put a check mark in the boxes labeled Other 1 or Other 2.
8. Under the Title column, type the name of the column.
9. Click the OK button.
10. Click OK to exit.

I've attached a screenshot for your reference.

Should you have any other questions along the way, feel free to ask us here in the Community.

Kind regards,

IntuitMike
