Revenue leakage costs 3 to 5 percent of revenue

MGI Research estimates revenue leakage costs at least 3 to 5 percent of revenue in most companies.

For a $50M business, that’s $1.5M to $2.5M a year in discounts outside policy, unbilled work, missed price increases and renewals nobody caught.

QTCFolio builds billing from the signed contract, so what you sold is what you bill.

The longer version

The estimate comes from MGI Research’s Revenue Leakage Series, Part 1. Leakage builds up in small gaps: billing staff re-create terms from PDFs, exceptions are approved in email and never reconciled, and services, price increases and renewals are missed because nobody saw them.

In QTCFolio the approved quote and signed contract become the billing record. Schedules are created from what the customer signed, with subscription, milestone, hybrid and verified-usage billing, payment terms and purchase orders. Amendments, co-termination and renewals flow through billing instead of around it.
