Accounts Payable / Finance

Every incorrect vendor record creates downstream risk, delays, and unnecessary clean-up for AP.

Validate vendor TINs before payment to prevent 1099 errors, IRS notices, and costly rework. When a vendor fails IRS matching, TIN Comply helps you resolve it fast using EIN discovery and secure W-9 requests—reducing year-end chaos and compliance risk.

Tax / Compliance

Tax and compliance teams are accountable for accuracy, documentation, and defensibility under increasing regulatory scrutiny.

Ensure IRS-compliant TIN matching with defensible audit trails and reduced backup-withholding exposure. Tin Comply helps teams remediate failed matches by collecting corrected W-9s and maintaining review-ready documentation.

Procurement / Vendor Management

Strong vendor management starts with accurate data at the point of onboarding.

Verify vendors before they enter your systems to prevent duplicate records and downstream issues. When a TIN match fails, Tin Comply provides remediation tools like EIN discovery and W-9 requests to quickly correct vendor information and keep onboarding moving.

Treasury / Payments / Fraud

Every payment carries risk when vendor identities aren’t fully validated.

Prevent payments to invalid or mismatched entities before money leaves your organization. Tin Comply adds a critical validation and sanctions screening layer, and helps resolve mismatches by requesting updated W-9s when vendor records can’t be verified.

Legal

High-stakes decisions require verified, reliable entity information.

Confirm you’re contracting with the correct legal entity and reduce regulatory and reputational risk. Tin Comply supports due diligence and defensible decision-making by validating taxpayer identity, screening against sanctions lists, and collecting updated W-9 documentation when needed.

IT / Data / ERP Teams

Modern finance and IT teams need validation embedded where data is created not bolted on later.

Integrate IRS-grade TIN validation, EIN discovery, sanctions screening, and W-9 remediation directly into your ERP workflows via API. Tin Comply improves data quality at scale while reducing manual fixes and downstream system issues.
