Automate Accounts Payable Processing

This skill designs automated accounts payable workflows spanning the full invoice-to-payment lifecycle - three-way matching, approval hierarchies, vendor management, and compliance controls. Every payment rests on a three-way match: the purchase order (purchase authorization), the goods receipt or service confirmation (proof of delivery), and the vendor invoice (payment request), all three required to agree on quantities, prices, and terms before approval. Segregation of duties is enforced throughout - invoice entry and approval performed by different people, payment authorization separated from execution, vendor master-file changes requiring dual approval, and bank account changes requiring C-level authorization - alongside exception management with tolerance thresholds for price and quantity deviations (typically 1-5%), escalation procedures for exceptions beyond tolerance, and documentation requirements for manual overrides.

Use it when designing or auditing an AP workflow that needs three-way matching, tiered approval limits, and SOX-grade internal controls - not a lightweight expense-reimbursement flow without purchase orders. It is not a substitute for the underlying ERP: it defines the workflow engine, approval matrix, and controls that sit on top of procurement, receiving, and payment systems, integrated via API rather than replacing them.

Given an incoming invoice, the workflow engine captures and validates data via OCR, performs the three-way match, and routes automatically within tolerance (5% price, 2% quantity) or escalates otherwise - final routing follows a configured approval matrix: department managers up to $10,000 with a 2% auto-approve tolerance, a finance director up to $50,000 requiring backup documentation, CFO approval up to $250,000 requiring board notification, and unlimited board approval requiring a dual signature, with dedicated exception routes for a missing PO (to procurement, 24-hour SLA), a price variance over tolerance (to the budget owner, justification required), and a duplicate invoice (to the AP supervisor, auto-hold). A duplicate-detection layer runs both exact matching (vendor ID plus invoice number) and fuzzy matching (similarity score above 0.8, date difference under 7 days, amount difference under 2% within a 30-day window). A payment scheduler selects among ACH (up to $1M, 1-day processing), wire ($10,000-$10M, same-day), and check (up to $50,000, 3-day processing), timing payments to capture early-payment discounts where the discount value exceeds $100, otherwise processing 2 days ahead of the due date.

Vendor onboarding runs through a vendor master table (unique tax ID, payment terms defaulting to NET30, payment method defaulting to ACH, encrypted bank account, W9-on-file flag, insurance certificate expiry, approval workflow fields) paired with a full audit-trail table logging every field change, who made it, and its approval status. A KPI dashboard tracks processing efficiency (average processing time, straight-through processing rate, exception rate), cost savings (early-payment discounts captured, duplicates prevented, cost per invoice), compliance (three-way match and approval compliance, segregation-of-duties violations), and cash flow (days payable outstanding, payment timing accuracy, forecast variance). API-first ERP integration keeps procurement, receiving, and AP systems synced in real time, with machine-learning-based GL coding and bank-platform integration for payment execution and reconciliation.

Finance and AP operations teams building or hardening an automated payables process who need concrete controls - encrypted and tokenized banking data, role-based access with regular reviews, positive-pay controls against check fraud, and regular SOX testing for public companies - plus process-optimization levers like e-invoice delivery (EDI, email, portal), OCR/ML-based extraction, vendor self-service portals, and dynamic discounting programs to optimize working capital.
