When DIY Valuation Makes Sense
Internal Strategic Planning
Rough estimates for growth planning, investment decisions, or internal benchmarking
Preliminary Assessment
Getting a ballpark figure before deciding on professional valuation
Educational Purposes
Learning valuation concepts and understanding your business better
Budget Constraints
When professional valuation isn't financially feasible and rough estimate suffices
Legal Proceedings
Divorce, litigation, shareholder disputes - courts require professional valuations
Tax Compliance
Gift tax, estate tax, charitable deductions - IRS requires qualified appraisals
Mergers & Acquisitions
Transaction values - buyers and lenders require professional valuations
Financial Reporting
GAAP compliance, impairment testing, purchase price allocation
The Hidden Costs of DIY Valuation
Time Investment
40-80 hours of your time to research, gather data, and perform calculations. At $100/hour opportunity cost, that's $4,000-$8,000.
Accuracy Risk
30-50% variance in DIY valuations. On a $1M business, that's a potential $300K-$500K error in negotiations or tax consequences.
Legal Liability
IRS penalties for inadequate appraisals can be 20-40% of tax underpayment. Legal challenges to DIY valuations often fail.
Why Professional Valuations Deliver Value
Credentialed Expertise
CVA, ASA, and ABV credentials require extensive training, experience, and ongoing education. Professional valuators understand complex methodologies and industry nuances.
Current Market Data
Access to proprietary databases with current transaction data, market multiples, and industry benchmarks that aren't available to the general public.
Legal Defensibility
Professional standards and documentation ensure valuations hold up in court, IRS audits, and regulatory review.
Multiple Methodologies
Professional valuators apply multiple approaches (income, market, asset) and reconcile results for more accurate conclusions than single-method DIY attempts.
Objective Perspective
Independent, third-party analysis free from emotional attachment or bias. Essential for negotiations, legal proceedings, and regulatory compliance.
ROI Through Accuracy
More accurate valuations lead to better negotiated prices, appropriate tax strategies, and defensible positions that often exceed the cost of professional services.
