Free tool for billable teams

Billable Leakage Calculator

Estimate how much revenue disappears when freelancers, agencies, and service teams forget to log billable work. Then see how Sandtime.io helps recover it without surveillance.

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$1,350.00
Annual leaked revenue$16,200.00
Monthly recoverable revenue$810.00
Annual recoverable revenue$9,720.00

That equals 18.00 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.
