Estimating app for contractors
The contractor estimating app you can talk to
Describe the job by voice, send a photo, or upload the plans. Arez writes an itemized estimate with materials, labor hours and your markup, and turns it into a proposal your client signs on their phone.
Free to download. 7-day free trial, no card to start. Or start on the web.

Three ways in
Start the estimate however the job allows
Talk through the job
Walk the job and say what you see, in English or Spanish. Arez writes the scope and the line items.
Snap a photo
Add a photo and the size. Arez reads it, lists what it assumed, and prices it. Correct anything in a sentence.
Upload the plans
Send a blueprint PDF and Arez takes off the scope from the drawings (Agency plan).
Every estimate
What you get back
Itemized, not a lump sum
Sections and line items with quantity, unit and price, so you and the client can see what the number is made of.
Your prices and your markup
Save your labor rates and markup once. Correct a material price and Arez uses your number next time.
Labor in hours
Every labor line is hours at your rate, so it is easy to check against how long the job really takes.
Options side by side
Good, better, best, or tile versus LVP, each with its own total in one estimate.
Edit by saying it
"Add a towel bar." "Make it a walk-in shower." The estimate updates and keeps the prices you set.
It learns how you bid
The changes you make to estimates teach Arez how you price, so the next one needs fewer edits.
Example
A 5x8 bathroom, from a photo

After the estimate
From estimate to signed job to paid
Proposal and e-signature
Turn the estimate into a branded proposal with your payment schedule. The client signs on their phone.
Change orders
Price the surprise, send it, and get it signed before the extra work starts.
Invoices and payments
Invoice from the job. Clients pay online by card or bank transfer.
Arez also runs the job once it is sold: scheduling, crew time, tasks and job costs. See the project management app for contractors.

Questions
Estimating app FAQ
What is the best way to start an estimate in Arez?
Whatever is quickest on the job: say it, send a photo with the size, or type a short description. If Arez needs one thing to price it, it asks; otherwise it states its assumptions and gives you the estimate.
How accurate are the estimates?
They are as good as the scope and the prices behind them. With your own labor rates and material prices saved, Arez estimates are a starting point you review, not a number to send blind. Nothing is sent to a client until you send it.
Does it work for my trade?
Arez is built for HVAC, plumbing, electrical, roofing, remodeling, painting and flooring contractors, and handles general remodeling jobs that cross trades.
Can I use it in Spanish?
Yes. Talk to Arez in English or Spanish, and the app is available in both languages.
Which phones does it run on?
iPhone, iPad and Android phones, and in a web browser at ai-arez.com/app.
How much does it cost?
Arez is free to download with a 7-day free trial. Plans are Starter $79, Professional $159 and Agency $259 per month. Blueprint analysis is on Agency.
