Variable size sku items - invoice feature

Variable size sku items - invoice feature

I sell a variable size product ranging from 1 foot x 1 foot to 20
feet x 100 feet and all sizes in between.

The program we now have allows us to enter ______feet x ________feet
and the program figures the total square area.

For example the invoice would read...

2 each of 3 Widgets 54" x 92" $43.00 each $215.00 total

Can or will Zoho be able to do this or how might I set up using your
existing tools?
