Variable size product codes

Variable size product codes

I sell by the my product by the square foot.

I would like 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?
