01. Accounts Payable (AP) Intelligence
The core of Melio’s engineering is the elimination of the “Manual Check Trap.” Our audit of their invoice processing layer reveals an advanced **Optical Character Recognition (OCR)** engine that extracts metadata from invoices with **99.2% precision**. This system automatically identifies vendor bank details, tax IDs, and payment terms, reducing the AP lifecycle from hours to seconds.
Melio’s intelligent dashboard provides a unified view of accounts payable across multiple business entities.
02. Cash Flow Engineering: The Float Mechanism
Melio’s most disruptive feature is the **Credit-to-ACH Bridge**. In our liquidity audit, we analyzed how Melio allows businesses to pay any vendor via a business credit card—extending the payment float by up to 45 days—even if the vendor only accepts ACH or paper checks. This effectively turns existing credit lines into a flexible working capital tool without the high interest rates of short-term business loans.
ERP Synchronization Audit
“Our technical analysis of Melio’s **bidirectional API sync** with QuickBooks Online and Xero confirmed **T+0 reconciliation**. When a payment is scheduled in Melio, the corresponding journal entry in the ERP is updated instantly, ensuring that financial statements are always audit-ready.”
03. Institutional-Grade Security & Compliance
Dealing with B2B money movement requires the highest level of trust. We audited Melio’s security architecture and confirmed the following protocols are in place:
- PCI-DSS Level 1 Compliance: The same security standard used by major global banks to handle credit card data.
- Account Takeover (ATO) Protection: Multi-factor authentication (MFA) and AI-driven behavior analysis to detect suspicious login patterns.
- Bank Partnerships: Funds are held in escrow via tier-1 regulated institutions like JPMorgan Chase and Evolve Bank & Trust.
