Time tracking and invoicing for service businesses and teams that bill by the hour. Log hours, track project budgets, and send invoices — all in one place. Integrates with 70+ tools. Free: 1 seat, 1 project. Paid: $10.80/seat/month (annual).
Harvest is a great fit if you run a service business — like a design agency, consulting firm, or law office — where you bill clients by the hour. The combo of time tracking, project budgets, and invoicing in one place saves you from juggling multiple tools, and the 70+ integrations mean it plays well with what you already use. The downside is the per-seat pricing adds up fast as your team grows, and the free plan is too limited (1 seat, 1 project) to be useful for most real businesses.
