If you’re running a small business in the US—whether you’re navigating the competitive real estate market in Brooklyn, scaling a tech startup in Texas, Austin, or managing logistics in Long Beach—your biggest enemy isn’t your competition. It’s the “hidden” cost of manual back-office chaos.

Our Core US Account Payable Services

1. Agentic AI & Human-Verified Capture

We’ve moved beyond basic OCR. Our 2026 “Agentic AI” doesn’t just read your invoices; it understands them. It flags price discrepancies against POs and identifies duplicates before they ever hit your ledger.

  • Localization Advantage: We handle all USD ($) transactions with real-time sync to QuickBooks, Xero, and Sage Intacct.

2. The 1099-Compliance Shield

The IRS has become more aggressive with reporting requirements. We manage your W-9 collection at the point of vendor onboarding, not in a panicked rush every January. We ensure your 1099-NEC filings are automated and 100% accurate.

3. Smart Cash Flow Orchestration

Why pay a bill today if you can safely pay it in 15 days? We strategically time your disbursements to maximize your bank balance while maintaining “Gold Status” with your American and international suppliers.

4. Zero-Trust Fraud Prevention

With the rise of sophisticated AI phishing in the US, we implement Multi-Factor Approval and Positive Pay integrations. No funds move without a rigorous, human-overseen “Segregation of Duties” protocol.
