ValuAdder Business Valuation Blog

For CPAs, accredited appraisers, and business brokers, the quality of your market comparables isn’t just a technical detail – it’s the foundation your entire opinion of value rests on.

When that foundation is controlled by a vendor, your defensibility is too.

In an era of vendor-locked valuation platforms and opaque proprietary databases, ValuAdder’s Multiples Maker gives appraisal professionals something rare: complete data sovereignty. Here’s why that matters – and what it means for the quality and defensibility of your work.

The Hidden Risk in Vendor-Locked Valuation Data

Many popular business valuation software platforms bundle data access directly into their subscriptions. At first glance, this feels convenient. In practice, it introduces four serious vulnerabilities to your appraisal work:

  1. Restricted scope and relevance. You’re limited to whatever the vendor chose to include. Industry gaps, geographic blind spots, deal size constraints, and transaction type exclusions are common – and rarely disclosed upfront.
  2. Opaque methodology. Pre-curated datasets may obscure how outliers were handled, what inclusion criteria were applied, or how adjustments were made. When a peer reviewer, auditor, or opposing expert asks you to defend your comparable selection, “the software’s database” is not a sufficient answer under USPAP, SSVS, or IVS standards.
  3. Data stagnation and selection bias. Vendor datasets update on the vendor’s timeline and may embed marketplace biases you can’t detect or correct. You have no mechanism to supplement with fresher or more targeted transaction data.
  4. Long-term cost and lock-in. Subscription models that bundle data access make it expensive to maintain, nearly impossible to migrate, and difficult to augment with superior external sources.

The result: valuations that may be technically generated but are vulnerable when it matters most.

Multiples Maker: Data Sovereignty for Valuation Professionals

ValuAdder’s Multiples Maker is built on a fundamentally different philosophy. Rather than locking you into one dataset, it functions as a vendor-agnostic analytical engine – accepting business sale transaction data from virtually any source and transforming it into clean, professional-grade valuation multiples.

Import from Any Source

Multiples Maker is compatible with premium commercial transaction databases, SEC EDGAR public filings, established industry sources, regional broker data, and – critically – your firm’s own proprietary transaction history that no third-party vendor will ever have access to.

Flexible Field Mapping

Column structures vary widely across data sources. Multiples Maker’s dynamic field mapping accommodates non-standard and irregular formats that rigid importers reject, so you’re never blocked by messy source data.

Precision Data Curation

Apply customizable outlier detection based on standard deviation thresholds, preview flagged data points before excluding them, and document every normalization decision. The curation process is yours to control and yours to explain.

Multi-Scenario Analysis

Run national database multiples alongside regional broker data, industry-specific collections, and internal historical transactions – all within a single project. Side-by-side scenario analysis gives you a comprehensive, multi-angle market basis no single-vendor tool can replicate.

The Professional Advantage: Accuracy, Traceability, and Defensibility

When you control the data pipeline, the downstream benefits are substantial:

Superior comparables quality. Flexible sourcing and user-driven curation produce cleaner, more relevant transaction sets tailored to the subject company’s size, geography, and industry – not whatever the vendor happened to collect.

Full methodology traceability. Every imported dataset and curation decision is documented within the ValuAdder project file. Demonstrating your methodology in a report, peer review, or litigation support engagement becomes straightforward.

Stronger professional defensibility. You can cite specific, high-quality sources – including proprietary ones – rather than deferring to a black-box database. That distinction matters in front of clients, tax authorities, and courts.

Broader market coverage. Blending public data, premium transaction databases, and exclusive in-house collections creates a comprehensive market basis that vendor-locked platforms simply cannot match.

The Bottom Line

Closed ecosystems and recurring data fees are the industry default. Multiples Maker is the exception – built for appraisal professionals who understand that independence, transparency, and data quality aren’t optional.

If you take pride in delivering high-quality, fully defensible valuations, control over your comparable data isn’t a nice-to-have feature. It’s a professional standard.
