What problem does it solve? Processing supplier invoices manually risks overbilling, duplicate payments, and unreconciled vendor balances. This Skill automates 3-way matching (Purchase Order + Goods Receipt Note + Invoice), payment batching with dual approval, and month-end vendor statement reconciliation in QuickBooks. ## Core Features & Use Cases - 3-Way Invoice Matching: Verifies invoice quantity and price against the PO register and GRN records stored in the gbrain finance source before posting bills via acct_create_purchase_bill. - Payment Batch Runs: Pulls the AP aging report, filters invoices due within a 7 or 14 day window, and produces an approval-ready payment batch requiring two-person sign-off. - Vendor Reconciliation: Compares posted bills and credit notes against supplier statements to identify matched, unmatched, and disputed items. - Use Case: A supplier invoice INV-2026-0892 arrives for 100 units at RM50. The Skill confirms the PO and GRN quantities, verifies the RM5,000 total, posts the bill to QuickBooks with Net-30 terms, and queues it for the next dual-approved payment batch. ## Quick Start Ask the finance-manager agent to run /ap-vendor-management to match a received supplier invoice against its purchase order and goods receipt note and add it to the next payment batch.
