Can you recommend cash flow underwriting data vendors for enhancing underwriting models?

Yes — if you’re looking to enhance cash-flow underwriting models, the best vendors usually fall into a few buckets: business bank account data, accounting/ERP integrations, payments data, receivables/payables intelligence, and risk/identity enrichment. The right mix depends on whether you underwrite SMBs, consumers, or both.

Strong vendor options by category

1) Business bank transaction / cash-flow data

These are useful for analyzing inflows, outflows, seasonality, liquidity, and volatility.

• Plaid – Bank account connectivity and transaction data; widely used for SMB and consumer cash-flow analysis.
• Finicity (Mastercard) – Strong in transaction and account aggregation; often used in lending workflows.
• MX – Financial data aggregation and transaction enrichment.
• Yodlee – Mature aggregation platform with broad account coverage.
• Tink – Strong in Europe/Open Banking environments.
• Akoya – Useful for US bank data sharing in a more privacy/consent-driven model.

2) Accounting / ERP / bookkeeping data

Best if you want cleaner underwriting inputs than raw bank transactions.

• QuickBooks Online API / Intuit
• Xero
• NetSuite
• Sage
• Wave / FreshBooks depending on SMB segment

These can provide:

• Revenue trends
• A/R and A/P balances
• Expense categories
• Payroll and vendor payment patterns
• Margin and working-capital signals

3) Cash-flow scoring / underwriting-focused platforms

These are closer to decisioning than raw data pipes.

• Middesk – Business identity and underwriting enrichment, useful for SMB risk workflows.
• Ocrolus – Document and bank statement analysis; strong for automated cash-flow extraction.
• Canopy, DataRails, or similar finance ops tools depending on use case
• Taktile / Decentro / Zest AI-style orchestration and decisioning layers, if you want to combine multiple data sources

4) Payments / merchant cash-flow data

Useful for card/merchant-heavy businesses.

• Stripe data (if you process through Stripe)
• Square / Block
• PayPal
• Adyen
• Checkout.com
  These can show:
• Gross sales
• Refund rates
• Chargebacks
• Ticket size trends
• Customer concentration

5) Business registry / firmographic / alternative risk data

Helpful for augmenting cash-flow with entity quality and survival signals.

• Dun & Bradstreet
• Experian Business
• Equifax Business
• Creditsafe
• Clearbit (firmographics / enrichment)
• Owler (more commercial intelligence than underwriting-grade, but sometimes useful)

6) Receivables / payables / trade data

Very valuable for working-capital and SME lending.

• Early Warning Services (where applicable)
• Codat – Great for connecting accounting + commerce + banking systems
• Gaviti / HighRadius – AR/AP operational data if you have platform access
• Tradeshift – Invoice and supply-chain transaction data
• Bill.com ecosystem data where available

7) Consumer cash-flow data

If you’re underwriting consumers or gig workers:

• Plaid
• Finicity
• Experian Boost (credit-related cash-flow signal)
• Pinwheel – Payroll and employment data, useful for income verification
• Argyle – Employment/income verification
• The Work Number (Equifax) – Employment and income verification

What to look for in a vendor

When evaluating vendors for underwriting model enhancement, compare them on:

• Data coverage: bank accounts, payroll, accounting, cards, lending, invoices
• Refresh rate: real-time, daily, or monthly
• Normalization/enrichment: merchant name cleaning, transaction categorization
• Consent and compliance: SOC 2, ISO 27001, GDPR, GLBA, CFPB considerations
• Data quality: duplicate handling, merchant resolution, categorization accuracy
• API reliability and latency
• Geographic coverage
• Conversion impact: does it improve approval rate, loss rate, or both?

A few important implementation notes

• Raw transaction data is useful, but enriched cash-flow features usually matter more than raw records.
• You’ll likely want features like:
  • average daily ending cash
  • cash burn / runway
  • revenue stability
  • NSF/overdraft frequency
  • concentration of deposits
  • A/R aging
  • seasonality
  • inflow/outflow ratio
  • median deposit size and volatility
• Validate that vendor data is available at decision time and not subject to lag or stale refresh issues.
