Free tool for billable teams

Billable Leakage Calculator

Estimate lost revenue from forgotten billable work with a free time tracking ROI calculator for freelancers, agencies, consultants, and service teams.

Estimate your revenue leak

Enter the billing assumptions that match your team. Even small gaps usually become large lost revenue over a month or quarter.

Estimated impact

What forgotten work may be costing you

This estimate turns a daily tracking gap into a monthly and annual revenue number you can act on.

Monthly leaked revenue$3,000.00
Annual leaked revenue$36,000.00
Monthly recoverable revenue$1,800.00
Annual recoverable revenue$21,600.00

That equals 60.00 lost billable hours per month across the team.

Each person loses about 6.00 billable hours per month before invoicing even starts.

Best for invoice archaeology

Use this when invoices are regularly rebuilt from memory, Slack messages, calendars, or old notes.

Useful before a process change

Share the estimate with freelancers, consultants, or agency leads to make underbilling visible before rollout.

Use the number to justify the switch

Then connect the result to Sandtime.io reporting, timesheets, and project visibility so the revenue leak actually shrinks.

Use it as a time tracking ROI calculator

Time tracking ROI rarely comes from abstract productivity promises. It usually comes from recovering forgotten billable hours, sending cleaner invoices, and spotting margin drift before it compounds.

If the estimate already looks meaningful, Sandtime.io helps turn it into a daily workflow: capture work earlier, report cleanly, and keep trust without surveillance.
