ShiftFlow for Independent Contractors
Track every billable hour, generate professional invoices, and stay on top of taxes — without the spreadsheet headache. ShiftFlow is the financial backbone of your contracting business.
Built for How Contractors Actually Work
Independent contractors juggle multiple clients, different billing rates, project deadlines, and a tax burden that most employees never think about. The average contractor spends 3-5 hours per week on administrative tasks — time that could be billable work.
ShiftFlow reduces that administrative overhead to minutes. Log project time in real time, generate accurate invoices from your logs, and let the AI handle tax calculations — so you can focus on the work that pays you.
