About SiteCalc® Pro
SiteCalc® Pro is an all-in-one construction business management platform for landscapers, sitework contractors, snowplow operators, and outdoor service businesses. It was built to help contractors move from first estimate to final payment without juggling separate tools for quoting, scheduling, invoicing, and payments.
Our Mission
We believe contractors should spend less time on paperwork and more time doing the work they love. SiteCalc® Pro brings estimating, professional quotes, job management, a client portal, invoicing, and online payments together so you can run your entire business from one place.
Meet the Founder
James Paterniti
Founder, SiteCalc® Pro
Built from real construction experience
I'm James Paterniti, founder of SiteCalc® Pro. I'm a civil engineer and former construction estimator and project manager with more than eight years of experience across private construction and municipal infrastructure.
My work has included preparing bids, estimating materials, labor, and equipment, coordinating field crews, and managing project budgets from planning through completion. That experience shaped how I built SiteCalc® Pro.
I created this platform to put practical estimating and business management tools within reach of small contractors and outdoor service businesses. My goal is to help owners price jobs confidently, stay organized, and grow with the right tools behind them.
Whether you're working on your own or growing a team, SiteCalc® Pro is built to help you account for the whole job and spend less time on paperwork.
