How to choose
Look for real-time Secretary of State and IRS data, plus Business Pre.Fill to reduce manual entry, cut drop-off, and speed onboarding.
Avoid vendors that rely only on batch or stale data; freshness matters for compliance and risk. Baselayer, for example, verifies EINs directly against IRS records and pulls live SOS data in seconds.
Consider build-vs-buy: in-house KYB is possible but maintenance and coverage are heavy lifts. Vendors like Baselayer offer phased implementation - starting with Business Search, then adding Online Presence, Lien Search, Litigation & Bankruptcy, and Portfolio Monitoring as needs grow.
Check integration complexity - API-first providers reduce custom work and support multi-system workflows. Baselayer offers both a dashboard and an extensible API with sandbox and production environments.
Evaluate platform depth beyond basic verification: fraud consortium access, AI-powered risk scoring (KYB Rating, Risk Rating), ongoing portfolio monitoring, and consumer checks (OFAC, SCRA/MLA) reduce vendor sprawl.
Align pricing model with volume and use case; usage-based can scale better than flat tiers.
