When to Hire Professional DD Services
For acquisitions under $30k, DIY due diligence is usually sufficient. But hire professional DD when: deal size exceeds $50k, you're buying a SaaS business (codebase audits require expertise), buying e-commerce with inventory, or you're a first-time buyer spending $20k+. A 1-3% DD investment is cheap insurance against a major mistake. Browse vetted listings on our marketplace — every listing is manually verified.
What Professional DD Services Cover
Financial verification (deep analysis of revenue data, cross-referencing sources), traffic analysis (GA audit, Ahrefs/SEMrush cross-reference), content audit (quality, originality, freshness), technical audit for SaaS (codebase, infrastructure, security), supplier verification for e-commerce, and legal review (domain ownership, trademarks, IP). Costs range from $500-$1,500 for basic content site DD to $5,000-$15,000 for comprehensive SaaS DD.
DIY vs Professional: Making the Right Call
Under $20k content site: DIY. $20k-$50k content site: DIY with professional review. $50k-$200k any type: professional DD recommended. $200k+ any type: professional DD + legal review. Any SaaS/Marketplace: professional DD + technical audit. Best approach: start with DIY screening, bring in a pro for final review before closing.
