Why we built this

A GC estimate isn't one trade's math — it's a dozen trades plus everything that keeps the job running. Describe the project and the estimator builds a line-item estimate by trade: self-performed labor, material packages, sub allowances for the trades you don't run in-house, plus the costs that quietly decide whether you make money — permits, dumpsters and disposal, temporary utilities, supervision and project management, all priced at regional market rates you can override.

This is the free version

In the app, it prices from your rates

The free generator uses market rates. Inside Trusso, the same engine anchors every line item to your personal price book, measures rooms with 3D scans, and sends estimates for customer approval — from your phone.

  • Estimates priced from your own rate book, not market averages
  • 3D room scans that measure walls, doors and windows for you
  • Send for e-approval, convert to a job, invoice when it's done
  • Leads auto-imported from Angi, Thumbtack, Yelp and Google

Frequently asked questions

How does the free general contractor estimate generator work?
It's powered by the same estimating engine inside the Trusso contractor app. It parses your project description, identifies which trades the scope touches, and builds line items for self-performed work, material packages, sub allowances and site overhead at regional market rates.
Does it include overhead, permits and project management?
Yes — those come out as their own line items rather than being buried in a lump sum, so you can see supervision, PM, permits and disposal separately and adjust each to your job.
Is it free?
Yes, no account needed. To save estimates, send them for e-approval, bill progress draws, or price from your own rate book, start a free 14-day Trusso trial.
How accurate is it on a multi-trade project?
It's a fast, structured first draft — useful for sanity-checking a budget or scoping a walkthrough. On real bids, replace the sub allowances with your actual sub quotes and add your contingency and markup before anything goes to a customer.
