Hello cbillings,

The option to add columns in the invoice template would be a good improvement to the product. At this time, we only have the option to add custom fields.

You might want to let our product engineers know that you want the option to add columns in the invoice form. I encourage you to send a feedback to our engineers by clicking the Gear icon and selecting Feedback.

Thank you for bringing that to our consideration, lyn. I'll also personally share this on my end. Your valuable suggestion will help us improve the customization look of our sales forms.
