General Contractor
Run every trade and subcontractor from one board. Track crew time straight to payroll, price and sign change orders in the field, bill progress draws, and watch live job margin — from the jobsite to the ledger, in a single app.
Bid to closeout
Everything a GC juggles across trades, subs and the office — connected end to end so nothing falls through the cracks.
Assign crews and subcontractors across all trades from a single dispatch board. Certs, tickets and expiries tracked per worker so no one's on site expired.
Crews clock in by job and cost code; GPS blocks off-site punches. Hours roll straight into payroll and job costing — no paper timecards.
Field crews raise work orders and material requests with zero prices on their screen. The office prices them, converts to invoices and POs, and auto-books the expense.
Capture, price and get change orders signed before out-of-scope hours are spent — tied straight to the invoice. Stop eating extras.
Labour, materials and subs roll up to real-time budget vs. actual per project, with margin alerts before you blow the number.
Toolbox talks, FLHAs, permits, submittals, punch lists and warranty — signed on site and filed as printable records. Your liability paper trail, digital.
