ContractorAI is an AI estimating, invoicing and CRM app for contractors, available for iPhone and iPad. ContractorAI's painting estimate calculator works out the paint, primer and labor a job needs. Enter each wall or surface by length and height, choose interior or exterior, the number of coats, paint quality and finish, surface condition and a waste factor, then set your labor rate and markup. You get an itemized painting estimate you can send from your phone.

PAINTING ESTIMATING PROBLEMS
Adding up wall areas room by room on paper is slow, and one missed wall throws off the whole quote.
Too little paint means a second trip; too much eats your margin. Coats, primer and surface condition all change how many gallons you need.
Rough surfaces need more prep and primer. If the quote ignores condition, you end up working for free.
A clear, itemized quote sent the same day is easier for a homeowner to approve.
PAINTING CALCULATOR FEATURES
Built for painters. Every number can be edited before you send the estimate.
Add walls and other surfaces by length and height, in feet or meters, for interior or exterior jobs.
Choose one or two coats, include primer, and apply a 5, 10 or 15 percent waste factor.
Economy, standard or premium paint in flat, eggshell, satin or semi-gloss.
Mark surfaces as good, fair or poor so prep and primer are part of the price.
Set your own hourly rate, material prices and profit margin so every estimate matches how you price work in your market.
Send a branded PDF, see when the customer views and approves it, then turn it into an invoice they can pay by card.
