Direct answer: Business Buyer Check and Rapid Diligence serve different stages. Business Buyer Check provides immediate, self-serve screening and document reconciliation from free to $249. Rapid Diligence publishes higher-priced human-led services, including Quality of Earnings work. The right choice depends on whether the buyer needs early triage or a professional engagement.

Who This Is For

Business buyers and advisers deciding what to verify, what remains unresolved, and what should change before closing.

What This Checks

  • Start With the Stage of the Deal
  • Compare the Work, Not Only the Price
  • Use a Staged Diligence Budget
  • Decision Questions

Start With the Stage of the Deal

A buyer reviewing listings usually needs fast triage: test price, SDE, financing pressure, missing evidence and public-record routes before committing thousands of dollars. A buyer under exclusivity with a complete data room may need accountants to perform defined procedures and stand behind a professional deliverable.

Compare the Work, Not Only the Price

  • Business Buyer Check: self-serve calculations, document reconciliation, evidence labeling and buyer actions
  • Rapid Diligence: published human-led vetting and Quality of Earnings services
  • Business Buyer Check does not issue an audit, appraisal or QoE opinion
  • A professional QoE may still be required by the buyer, lender, investor or deal complexity

Use a Staged Diligence Budget

Run the least expensive test that can answer the current decision. Reject weak opportunities early. If the deal survives, use contradictions and missing support to define the professional scope. This sequencing can reduce wasted effort without treating software as a substitute for an accountant or attorney.

Decision Questions

  • Do you have only a listing, or a complete financial package?
  • Do financing parties require an independent report?
  • Are records inconsistent, cash-heavy or unusually complex?
  • Do you need a same-day screen or a staffed engagement?
  • Who must rely on and defend the final conclusion?

Illustrative Buyer Example

How a Buyer Would Apply This Guide

A seller’s headline earnings support the asking price, but the supporting records are incomplete. The buyer follows this guide to identify the missing inputs, reproduce the calculation, request independent support, model the downside, and convert unresolved items into offer protections rather than treating the claim as verified.

Classification: Illustrative analysis—not a live finding, valuation conclusion, or recommendation to buy.

Official Sources and Verification Routes

Use the exact legal entity, address, filing number, license number, facility identifier, or carrier identifier shown in the source. Access, coverage, fees, and update timing vary.

Frequently Asked Questions

Is Business Buyer Check the same service as Rapid Diligence?

No. Business Buyer Check is self-serve acquisition decision support. Rapid Diligence publishes human-led diligence services. Compare current scope, timing, reliance and deliverables directly with each provider.

Can DealProof replace Rapid Diligence’s Quality of Earnings work?

No. DealProof can reconcile authorized records and identify contradictions, but it does not provide a CPA-led Quality of Earnings opinion.

When should a buyer move to professional diligence?

When the opportunity survives screening and the price, complexity, financing, record quality or reliance needs justify a professional engagement.

This educational material is preliminary decision support, not legal, tax, accounting, lending, appraisal, or investment advice. Requirements and transaction terms vary; verify current rules with qualified advisers and official sources.
