Choose Clockify if

  • You mainly need people to log hours, and cost is the deciding factor.
  • You want a free plan, or native desktop and phone apps.
  • You bill from another system and only need timesheet exports.

Choose Posttime if

  • You are a UK practice and the timesheet has to become an invoice without retyping.
  • You invoice through QuickBooks Online.
  • You want recovery reporting on fixed fees, approvals on write-offs, and client records filled from Companies House.
  • You would rather pay in pounds with no VAT to add.

Posttime is not a full practice management system and does not connect directly to Xero. The guide for accountants explains where it fits, and the wider comparison also covers Toggl Track, Harvest and Timely.
