FAQ

Common questions

What does waste factor do?

Waste factor increases the base quantity to account for cuts, breakage, mistakes, or overage. It helps avoid under-ordering.

Can this work for different materials?

Yes. Use the coverage value that matches your material unit, such as square meters per box or liters per can.
