Direct answer
A digital agency should choose Harvest over Toggl Track because Harvest includes native client invoicing, direct expense receipt management, and deeper built-in accounting workflows that reduce administrative overhead compared to Toggl Track's external invoicing dependencies.

Toggl Track excels in lightweight, frictionless timer convenience across more than 100 web integrations, making it a favorite for pure timekeeping speed.

FAQ

- Which platform has a better browser extension timer for digital agencies?
- Toggl Track is widely praised for having the fastest, most frictionless browser extension with idle-detection features. However, Harvest's browser extension is also robust, supporting seamless start/stop tracking across web tools like Asana, Trello, and GitHub.
