Two calculators, one goal: know what your hours are really worth. Pick one, adjust the sliders, and the results update as you type.
No black box: four inputs, one multiplication, and a realistic recovery target.
We multiply your fee-earning team by their average charge-out rate, the unrecorded hours each person loses in a week, and your chargeable weeks in a year. That is revenue your practice earned but never invoiced.
Timesheets filled in on Friday afternoon rely on memory. The quick client call, the extra site visit, the design change discussed over email: small entries that are individually forgettable and collectively expensive.
You will not capture every minute, so the recovery slider lets you choose a realistic share. Even recovering half of the leakage can be worth many times the cost of the software used to capture it.
Quantim makes logging time the easy path: daily or weekly timesheets, a mobile app for on-site logging, and automated reminders, so hours are recorded when the work happens and flow straight through to fees and invoices.
Recovery only happens when logging is effortless. Quantim gives every person on the team a timesheet style that fits the way they actually work.
Log each day's work against jobs and activities while it is still fresh. The detail-first option.

Hit start when work begins and stop when it ends, and Quantim works out the hours for you.
