A playable mock-up with sample project data, right here on the page. Start a timer, add the entries that usually get forgotten, then watch them flow through to the fees and the invoice.
Thu 20 Aug 2026 Fee reportThe demo is a simplification, but the principle is the real thing: an hour is recorded once and then flows through fees and invoicing without being retyped.
Daily and weekly timesheets, a timer, and a mobile app for site work. The easier logging is, the more of your chargeable time actually reaches a timesheet instead of being reconstructed on a Friday.
Recorded hours become work in progress at each job's own rates, so you can see unbilled fees building through the month rather than discovering them at the end of it.
Invoice lines are built from the hours already recorded, so nothing is typed twice and nothing quietly drops out between the timesheet and the bill.
To size the gap for your own team first, the timesheet ROI calculator estimates what unrecorded hours cost you over a year.
Every one of these is free, needs no signup, and works its answer out in your browser. Nothing you type is saved or sent anywhere.
See what unrecorded billable hours cost your practice over a year, and what capturing them could recover. Includes a charge-out rate and margin calculator.
