What is revenue leakage and how does it affect home services and contracting businesses?

Revenue leakage is money a business is earning the right to collect but failing to capture — through unbilled change orders, uninvoiced materials, pricing below actual cost, jobs closed without final payment, or service work that was completed but never entered into the billing system. It is distinct from lost sales. The work was done. The cost was incurred. The revenue simply was not collected. For most trades businesses, leakage runs between 8 and 18 percent of gross revenue.

What are the most common sources of revenue leakage in a contracting business?

The five most common sources are: change orders that are agreed verbally but never invoiced, materials purchased for a job that are not allocated to that job's cost and billing, technician time on-site that exceeds the estimate without a corresponding price adjustment, invoice delays that push collection past 60 days and increase write-off risk, and service agreements or maintenance contracts that lapse without renewal follow-up.

How does Oscker identify and quantify revenue leakage in a diagnostic?

Every Blueprint engagement includes a revenue leakage analysis as a core component. David reviews job cost reports, invoice records, change order logs, and collections aging during the on-site diagnostic. Each leakage category is identified, estimated in dollar terms, and mapped to the specific process gap causing it. The Blueprint then sequences the fixes by recovery value — highest-dollar leakage addressed first.
