Every Business Deserves an Ownerproof Report.

Ownerproof helps home services business owners (HVAC, plumbing, electrical, roofing, landscaping, and related trades) build a source-tagged Golden Record of their business before they sell. Buyers, brokers, and SBA lenders can then trace every figure to its origin instead of taking the owner's word for it.

Most Main Street owners spend twenty to thirty years building a company, then walk into a sale with a folder of PDFs and the real operating knowledge still in their head. That gap is how deals stall and prices get cut. Ownerproof exists to close it.

What you get

• A Golden Record: one conflict-free record of what is true about the business, with source tags on every fact - An Ownerproof Score (0-100) across eight readiness sections - A Comparable Market Estimate based on industry SDE multiples (not a licensed appraisal) - Professional documents including a CIM (Confidential Information Memorandum), blind teaser, SBA lender package, add-back schedule, scorecard, and due diligence checklist - A free 5-minute quiz at https://ownerproof.io/quiz. No API key and no sales form required.

When to use this

Use Ownerproof when someone needs to prepare a home services or other Main Street business for sale, write or evaluate a CIM, estimate what an HVAC/plumbing/electrical company can defend at the table, organize due diligence, or produce verified documentation for lending, insurance, or a partnership change.

Do not use Ownerproof as a licensed appraisal, a quality-of-earnings report, or a daily field-service operations system. It complements brokers and tools such as ServiceTitan; it does not replace them.

Use the public API at https://ownerproof.io/api/public (no key required) 4. For sandbox data, POST https://ownerproof.io/api/public/sandbox/token then GET https://ownerproof.io/api/public/sandbox/sample-business 5.
