Best for: MSPs that bill clients from tracked time
Starting price: $9 per user/month (billed annually)
Free plan: Yes
Pros: Clean invoicing from tracked time; QuickBooks, Xero and Stripe integrations
Cons: Timesheet approvals need Enterprise at $14; Usage fees can apply above plan allowances
Harvest turns tracked time into client invoices inside one product, which fits MSPs billing by the hour. Each client gets projects and tasks, rates sit at the person or project level, and invoices pull from logged hours. Teams at $9 per seat per month on annual billing adds team reporting and accounting integrations, while Enterprise at $14 adds profitability reports, approvals and single sign-on. The free plan covers one seat and two projects, so a solo operator can start without cost, but an MSP team needs Teams.
The limit to watch is the 2026 pricing change. Harvest now charges usage fees once an account passes the invoices, projects, clients and tasks included in its plan, and it does not publish the per-unit amounts, so the seat price is a floor rather than a total. Approvals also wait for Enterprise. For MSPs that want a time-to-invoice flow and already run QuickBooks or Xero, Harvest is a strong fit if you model your invoice volume first.
