How AI construction estimating works in Arez
Traditional estimating software asks you to build the estimate: pick items from a cost database, measure, multiply, add markup. That works for a full-time estimator. For a contractor who estimates between jobs, it is the part that never gets done on time.
In Arez you describe the work the way you would to a foreman, by voice or text, or send a photo with the size, or upload a plan PDF. Arez writes the line items, states what it assumed, and prices it with your labor rates and markup. You review it, change anything by saying it, and send it. Nothing reaches a client until you send it.
What it does
Everything a small contractor needs, in one app
AI estimates in less than 1 minute
Describe the job by voice or text, send a photo, or upload plans. Arez writes an itemized estimate with materials, labor hours and your markup.
Your prices, not a generic book
Save your labor rates and markup once. Correct a material price and Arez uses your number on the next job.
Options side by side
Good, better, best, each with its own total in one estimate, so the client picks without a second quote.
Estimates from blueprints
Upload a plan PDF and Arez takes off the scope from the drawings (Agency plan).
Proposals clients sign on their phone
Turn the estimate into a branded proposal with your payment schedule. The client reviews and e-signs it from a link.
Change orders, signed before the work
Price the extra, send it, and get a signature before your crew starts on it.
Example
A roofing job, start to finish
Arez lists what it assumed (one layer tear-off; 10% waste on shingles; decking in good condition), prices every line with your rates and your 20% markup, and you send it as a proposal. More on the Roofing estimating app page.

This table describes each kind of tool in general; features and plans change, so check each product before you buy. If you run large commercial projects with a dedicated office staff, a construction suite is built for that. If your business is mostly recurring service visits and dispatch, a field service app fits better. Arez is for the contractor who wants the estimate written for them and the job run from a phone.

Questions
Construction estimating software FAQ
How accurate is AI construction estimating?
As accurate as the scope and the prices behind it. With your own labor rates and material prices saved, an Arez estimate is a starting point you review, not a number to send blind. It lists what it assumed so you can correct it in a sentence.
How fast is it?
Usually less than 1 minute from when you describe the job to an itemized estimate.
Can it estimate from blueprints?
Yes. Upload a plan PDF and Arez takes off the scope from the drawings. Blueprint analysis is on the Agency plan.
Are labor and materials separated?
Yes. Every estimate has sections and line items with quantity, unit and price. Labor lines are in hours at your rate, and markup is applied to the whole job at your saved rate.
Can I use my own prices?
Yes. Save your labor rates and markup, correct any material price, or import your price list from Excel or a PDF. Arez uses your numbers on the next estimate.
Which trades does it estimate?
HVAC, plumbing, electrical, roofing, remodeling, painting, flooring and handyman work, plus remodels that cross trades.
How much does it cost?
Arez is free to download with a 7-day free trial and no card to start. Plans are Starter $79, Professional $159 and Agency $259 per month. Blueprint analysis is on Agency.
