MSP billing leakage calculator
Unbilled time, licenses that never made it onto an agreement, and forgotten products add up. Estimate your annual revenue leakage in under a minute.
How this calculator works
- Unbilled time = billable hours × % never invoiced × hourly rate.
- Unbilled licenses = seats missing from agreements × price per seat.
- Annual leakage = (time + licenses + products) × 12.
- Defaults are illustrative — audit a recent month of invoices for real inputs.
Where MSP billing leaks
Common sources are time entries left on tickets that never reach an invoice, vendor license counts that grow faster than agreements, and hardware or expenses procured but not billed.
Leakage tends to be small per item and large in total, which is why it often goes unnoticed until someone reconciles vendor bills against client agreements.
How to reduce it
Reconcile vendor invoices against agreements every month, require time entries before tickets close, and link procurement to quotes so every purchase has a billing destination.
Corei continuously matches vendor costs to client agreements and flags gaps for review; it never issues, voids or credits invoices on its own.
