Pro is $45 per month per site, with unlimited users either way.
It adds profit and margin reporting by job, crew, worker and job classification, the Profits dashboard and Job Pulse, invoicing, online card deposits and invoice payments through Stripe, the AI tools, the vehicle mileage and expense log, overhead expense tracking with a year summary, vendor spend and 1099 reporting, and year-end reports for your accountant.
The free plan is not limited or time-restricted. It keeps working exactly as it does now if you never upgrade.
