Time Tracking for Subcontractors & 1099 Workers
What to track for billing and project control without treating independent contractors like employees on paper—practical boundaries and questions for your accountant.
Last updated: March 28, 2026
General contractors, agencies, and field service companies often blend W-2 employees and 1099 subs. Time tracking can help prove work completed and support client invoices—but it is not a substitute for correct classification. Software should follow policy; it should not define it.
This article is educational, not legal advice. Pair it with payroll for contractors (W-2 vs 1099) and tracking billable hours. Explore time tracking comparisons when you shortlist vendors.
Classification Cautions
Control, tools, and documentation.
Courts and agencies look at behavioral and financial control—not only what your time app is named. Excessive direction, mandatory always-on monitoring, and exclusive scheduling can undermine 1099 status depending on facts. Align tools and contracts with counsel-approved playbooks.
Workflows That Stay Arm’s-Length
Invoices, retainers, milestones.
Many subs invoice on milestones or lump sums; others log hours to a client code you provide. Decide whether subs self-report into your system or send invoices with backup attachments. The cleaner the handoff to invoicing, the fewer disputes you will see at month-end.
Field Crews and Mixed Labor
Field service and trades.
On job sites, separate W-2 time (often with stronger attendance policy) from subcontractor deliverables. If you use geofencing, read geofenced time tracking for field crews and ensure policies differ where appropriate.
