Quick verdict
How these two tools differ.
Harvest is opinionated toward agencies and service teams: you log hours and expenses, then turn them into invoices. That makes it a strong fit if your client billing, budgets, and project reporting should live in one product.
Clockify is more flexible and value-focused. Its free plan and low-cost tiers let you roll tracking out across a large team, then layer approvals and monitoring when needed.
Pick Harvest when you want tracking plus billing in one place; pick Clockify when budget and headcount matter more than built-in invoicing.
