ServiceTitan is a powerful platform — for operations running 20+ technicians with office staff to manage it. If you're a solo operator or small crew that just needs professional estimates out the door fast, you don't need weeks of implementation. You need a photo, two minutes, and a signed PDF.
ServiceTitan pricing is quote-based, but industry surveys consistently put it in the hundreds of dollars per technician per month, plus onboarding fees that can run into the thousands. That math works when the software is managing twenty trucks, a call center and a marketing budget. For a three-truck shop, the same line item buys a lot of features that never get opened. Fast Estimate charges a flat $99.99 a month for the whole company — the trade-off is scope: it does estimating, signatures, deposits, invoicing and job scheduling, and deliberately nothing else.
The second difference is time-to-value. ServiceTitan implementations are measured in weeks and involve data migration specialists and training sessions — reasonable for an enterprise rollout, painful for a shop that needed quotes out the door yesterday. Fast Estimate is self-serve: contractors typically send their first signed estimate the same afternoon they create an account. If your bottleneck is quoting speed rather than dispatch coordination, that is really the whole decision.

The enterprise-grade field service operating system for large HVAC and trade businesses.
No — and it doesn't try to be. Fast Estimate focuses on estimating: AI-drafted line items, branded PDFs, e-signatures, deposits and follow-ups. It doesn't do dispatch, payroll or marketing attribution. If those are why you pay for ServiceTitan, keep them; many small shops simply never needed them.
Most contractors send their first estimate the same day they sign up. Add your company details, optionally import your price book CSV, and the AI is ready — there's no implementation team or training program because there's nothing complicated to learn.
Yes. The flat $99.99/month plan includes unlimited technician seats, so every tech can quote from their phone and every install can be assigned to a crew member on the job calendar.
