How can I add a column with the number of items or hours of service provided on an invoice?

Hello there, @jjfoot!

Let's go ahead and customise your invoice template so we can add the Quantity column. This way, the total number of items or hours of service used will show up on your invoices.

1. Go to the Gear icon.
2. Under YOUR COMPANY, select Custom Form Style.
3. Find the invoice template you wanted to edit.
4. Below the ACTION column, select Edit.
5. Click Content.
6. Select the center part of your invoice template.
7. Under COLUMNS, select Quantity.
8. Click Done.

In addition, here's an article you can read to learn more about how you can customise an invoice template: Customise invoices, quotes, and sales receipts in QuickBooks Online.

Lastly, I've got you this helpful article for ideas about adding a company logo in your invoice template: Add, customise, or remove logos on sales forms.
