Built by Builders. Made for Contractors.
OnSite is contractor management software for the people doing the work — fast estimates, professional invoices, and the tools you need to win more bids and keep more profit.
Our Mission
Most contractor software is built by people who have never swung a hammer. We started OnSite because we watched too many good contractors lose money on bad estimates, get crushed by paperwork, and miss out on jobs because their pricing took too long.
Our mission is simple: give independent contractors and small trade businesses the same speed, polish, and pricing intelligence that the big firms pay tens of thousands for — at a price that actually makes sense.
What We Believe
Three principles shape every feature we ship.
Speed Wins Jobs
The contractor who gets the estimate out first usually gets the work. We measure success in seconds, not hours. A 60-second estimate isn't a gimmick — it's how you win the bid.
Honest Pricing
Contractor software shouldn't cost more than a truck payment. We keep our pricing flat, transparent, and built for solo operators and small crews — not just enterprise.
Tools That Work in the Field
If it doesn't work on a phone, in a driveway, with one bar of signal — it doesn't work. Every feature in OnSite is tested where contractors actually use it.
By the Numbers
The Story Behind OnSite
OnSite started as a side project to fix a real problem: a friend in the trades was losing nights and weekends to spreadsheet estimates, only to underbid jobs anyway. The first version was a single calculator built to spit out accurate numbers in under a minute.
Contractors started asking for invoicing. Then CRM. Then a way to manage leads, track profit, and run their entire business from a phone. Today OnSite is an all-in-one platform serving contractors across roofing, HVAC, plumbing, electrical, painting, and general construction.
We're still independent, still small, and still built around one rule: if a feature doesn't help a contractor make or keep more money, it doesn't ship.
