Use case · Payroll & W-2

Payroll & W-2 extraction. In seconds.

Income verification, employment proof, KYC — the workflows depend on payroll docs being structured fast and right. fluex extracts gross pay, net pay, employer, employment dates, withholdings, and YTD figures from US payslips, W-2s, paystubs, and 1099s in under three seconds, with a complete audit trail behind every extraction.

Why payroll docs are uniquely hard

US payroll documents come in dozens of layouts because every payroll provider — ADP, Paychex, Gusto, Workday, Rippling, Justworks — formats them slightly differently. The fields that matter for downstream workflows (gross, net, federal/state withholdings, FICA, YTD, employer EIN) live in different places across formats. Manual data entry is slow and error-prone; rigid template-based OCR breaks the moment a customer's payroll provider updates their layout.

How fluex does it

fluex uses a multi-LLM ReAct architecture that recognizes payroll documents semantically rather than positionally. The platform identifies the document type (W-2 vs 1099 vs paystub vs verification letter), extracts the canonical fields into a normalized schema, and validates them against expected ranges and consistency rules. The result is the same JSON shape regardless of which payroll provider produced the original PDF.

What you get out of the box

Provider-agnostic

Same schema for ADP, Paychex, Gusto, Workday, Rippling, Justworks — and any provider you haven't seen yet.

All US payroll docs

W-2, 1099-NEC, 1099-MISC, 1099-K, paystubs, employment verification letters, offer letters.

YTD & period parity

Cross-checks YTD figures against period totals and flags inconsistencies before they hit your underwriting model.

PII-aware audit trail

SSN and tax-ID values are redacted in audit metadata by default. Full extraction is retained per your retention policy.

Integration patterns

The REST API takes a multipart upload or a signed URL and returns structured JSON in 2-3 seconds. For higher volumes, async mode with webhooks scales to thousands of documents per minute. SDKs are available for Python, Node.js, Ruby, Go and .NET. Pre-built integrations exist for Salesforce, HubSpot, n8n and Zapier.

Compliance & trust

Payroll documents contain SSN, employer ID, and other regulated identifiers. fluex retains them encrypted at rest with per-tenant keys and offers configurable retention (default 90 days, can be 0). Audit metadata is redacted to mask PII by default. See our trust page for the full posture: encryption, tenant isolation, sub-processors, GDPR DPA, CCPA, SOC 2 Type II in progress, and HIPAA BAA on Enterprise.
