Micro-Business: The Smallest Businesses with the Biggest Data Gap

February 5, 2026

Understand micro-businesses—the smallest segment of the business population and why they present unique KYB verification challenges.

A micro-business is the smallest category of business, typically defined as having fewer than 10 employees and minimal revenue. Micro-businesses represent the vast majority of all businesses but are often invisible to traditional business data sources.

Defining Micro-Business

Common Definitions

US SBA: Fewer than 10 employees

European Union: <10 employees, <€2M turnover

World Bank: 1-9 employees

Practical: Owner-operated, often no employees

Most definitions align on:

  • Very small headcount (often just the owner)
  • Limited revenue (typically under $1M annually)
  • Simple operations
  • Often home-based or mobile

Scale in the US

  • ~32 million businesses in the US
  • ~81% have no employees (owner only)
  • ~88% have fewer than 20 employees
  • Micro-businesses are the norm, not the exception

The Data Gap Problem

Thin-File Businesses

Traditional business data assumes:

  • Corporate filings with the state
  • Business credit history
  • Commercial banking relationships
  • Published financials

Micro-businesses often have:

  • No corporate structure (sole proprietors)
  • No business credit file (use personal credit)
  • Personal bank accounts for business
  • No public financial data

Why Micro-Businesses Are Invisible

Secretary of State: No filings if unincorporated

Dun & Bradstreet: No DUNS if never sought credit

Commercial data: Below reporting thresholds

Business registries: Local licenses only

Web presence: May not have website

The Verification Paradox

The businesses that need the least scrutiny (small, simple, local) are often the hardest to verify because they generate the least data.

Micro-Business Characteristics

Structure

Most micro-businesses are:

  • Sole proprietorships (no legal entity)
  • Single-member LLCs
  • Partnerships between family/friends

Complex structures are rare—there's no tax or liability benefit to complexity at this scale.

Operations

Typical patterns:

  • Home office or client sites
  • Service-based rather than product-based
  • Local customer base
  • Cash flow-dependent
  • Seasonal or variable income

Lifecycle

Micro-businesses have distinctive patterns:

  • High formation rate
  • High failure rate (especially in first 2 years)
  • Often transition to larger structures if successful
  • Many are "lifestyle businesses" not growth-oriented

KYB for Micro-Businesses

The Challenge

Standard KYB assumes:

  1. A legal entity exists
  2. State records document it
  3. Business data providers have information
  4. Ownership can be verified through filings

Micro-businesses often fail all four assumptions.

Alternative Verification Approaches

For micro-businesses, verification pivots to:

Identity-centric verification:

  • Verify the owner (since owner = business)
  • Check personal credit as proxy for business
  • Confirm address and contact information

Activity-based verification:

  • Bank statements showing business transactions
  • Payment processing history
  • Tax returns (Schedule C)
  • Invoices and contracts

Presence verification:

  • Website and social media
  • Google/Yelp business listings
  • Local business licenses
  • Professional certifications

Proportional Verification

Risk-based KYB for micro-businesses:

Low (small transactions): Owner identity + basic business confirmation

Medium: Add activity verification (bank, payment data)

High (larger volumes): Full documentation, potentially site visit

Over-verifying micro-businesses creates friction that drives them away. Under-verifying creates risk exposure.

Risk Considerations

Why Micro-Businesses Aren't Necessarily High Risk

  • Clear ownership (usually one person)
  • Limited transaction volumes
  • Local reputation matters
  • Owner's personal assets at stake

Why They Can Be Higher Risk

  • Thin credit history
  • Limited financial cushion
  • Higher failure rates
  • Harder to investigate if problems arise
  • May be fronts for cash-intensive illicit activity

Industry-Specific Risk

Risk varies dramatically by micro-business type:

  • Low risk: Professional services, established trades
  • Medium risk: Retail, food service
  • Higher risk: Cash-intensive, high-ticket, cross-border

Micro-Businesses and Compliance

Regulatory Proportionality

Compliance requirements often scale with business size:

  • Corporate Transparency Act exempts very small businesses in some cases
  • Anti-money laundering thresholds consider transaction volumes
  • Industry licensing varies by activity type and scale

The Onboarding Friction Problem

Requiring enterprise-level documentation from micro-businesses:

  • Creates abandonment at onboarding
  • Discriminates against legitimate small businesses
  • Doesn't actually reduce risk proportionally
  • Misses the forest for the trees

Effective KYB tailors requirements to the actual risk profile.

Key Takeaways

  • Micro-businesses are the majority of all businesses but the most data-sparse
  • Traditional business data sources miss them—different approaches needed
  • Owner identity often equals business identity—KYB overlaps with KYC
  • Activity-based verification supplements identity—bank data, payments, tax records
  • Proportional verification matters—over-verification creates friction without reducing risk
  • Risk varies by industry and activity—not all micro-businesses are equal
