Best for: agencies that want timer to invoice in one place
Starting price: $9 per seat/month (billed annually)
Free plan: Yes, 1 seat and 2 projects
Pros: invoicing built in, with expenses and billable rates on each entry; clean reports by client, project and person
Cons: no screenshots or activity tracking; Flex usage fees apply for active projects, clients, tasks and invoicing; free plan covers 1 seat and 2 projects only
Harvest fits an agency that bills by the hour, because the path from timer to invoice is short. A team member logs time against a client and a task, the lead reviews the week, and Harvest turns approved hours into an invoice with the right rates already applied. Teams costs $9 per seat per month billed annually, with a 30-day trial, and Enterprise at $14 adds single sign-on, custom roles and a dedicated success manager.
The trade-off is proof. Harvest has no screenshots and no activity tracking, so a client who wants evidence beyond the timesheet will need another tool. The Flex usage fees on active projects, clients, tasks and invoicing add to the seat price, so an agency with many small clients should model the full bill. The free plan covers a single seat, so any real agency will pay from day one.
