Clockify

Clockify has become the default time tracking tool for budget-conscious agencies, and its free tier is genuinely generous. Unlike competitors that charge per user, Clockify offers unlimited users at no cost, with core features like timers, timesheets, and project-level reports included. For agencies that need to track billable hours but can't justify the per-seat cost of tools like Toggl Track or Harvest, Clockify is the obvious starting point.

The reporting capabilities are strong even on the free plan. Agencies can break down tracked time by project, client, team member, or date range, making it straightforward to analyze where hours are going and whether projects are on budget. Billable rates can be set per project or per team member, and the resulting reports feed directly into invoicing conversations — though you'll need a separate tool for actual invoice generation.

Compared to Toggl Track, Clockify trades some polish and advanced analytics for a dramatically lower price point. Compared to Harvest, it lacks native invoicing but offers more flexibility in team size. For agencies that just need reliable time tracking with solid reporting, Clockify punches well above its price tag. The paid plans add timesheet approvals, scheduling, and more granular permissions, but many small agencies never need to leave the free tier.
