Job Assistant is an all-in-one, mobile-first field-service app for contractors, handymen, and general contractors. From a phone in the field, you can send professional estimates, get contracts signed, invoice customers, and accept online card payments — then track expenses, mileage, and profit with built-in bookkeeping. The General Contractor plan adds crew and subcontractor management, scheduling, and job-costing. Job Assistant replaces the patchwork of paper, spreadsheets, and multiple apps that small contractors juggle — helping them look professional and get paid faster.
