In the past I've gone off square footage

On those projects did you end up making the profit you were expecting/hoping for ?

Are you familiar with job costing ? Having you been tracking your labour hours and material costs for every project?

When I started out, coming up with prices for painting projects was really hit or miss in terms of profit and i really struggled. Until I learned about job costing (google nick slavik job costing).

If you keep track of two simple data points and make a spread sheet you will quickly be able to see if you are under pricing or possibly your production rates are inefficient or both!

Keeping track of your Lead to sale generation is also really important but that's a different subject.
