For an eCom site powered by WooCommerce I have the gravity add-on and GF.
What I'm stuck with is this:
We have variable products [size, color] which usually will have a quantity of at least 10 ordered.
For selected product I need [i assume via GF best?] to add the customization options, where there's a fixed setup fee plus a cost per unit ordered. Other upgrade option is without setup fee only a per unit fee.
And that this gets added to total.
How do I program this? Do I need mathematical formulas :( ?
Your help much appreciated.
Please someone HELP!
