Invoice Subtotals via Category

Greetings!

Is there ANY way to modify an invoice template to provide a category subtotal?

–WHY?–
To save time on the hardware prepay that we expect from customer at the beginning of a project. Without the hardware prepay, our cash get tied up WAY to fast. Right now we have to calculate this manually. It would be nice to

IE - Line Item Subtotal

Invoice 1

Name QTY Price
Hardware 1 1 100
Hardware 2 2 200
Hardware Subtotal 500

Labor 1 1 200
Labor 2 2 300
Labor Subtotal 800

------> OR <--------

End of Invoice Sutotals

Invoice 1

Name QTY Price
Hardware 1 1 100
Hardware 2 2 200
Labor 1 1 200
Labor 2 2 300

Hardware Subtotal 500
Labor Subtotal 800
Subtotal 1300
Tax 100
Total 1400

Hi Cole! Currently, there isn’t any way to do this. The template editor can do template tags and you can change the styles but there isn’t a way to add categories for the subtotals. I’ll go ahead and move this to the Feature Request section as this is a great idea!
