Add Three-Way Matching for Purchase Orders, Receiving Reports & Invoices

This request will need detailed planning and input from more users to build, but would be a significant upgrade/value add to the software.

Three-way matching is the accounting process of comparing a purchase order, receiving report, and vendor invoice to verify accuracy before approving payment.

Three-way matching is important in accounting because it helps ensure that a business only pays for goods that were actually ordered and received. By comparing the purchase order, receiving report, and vendor invoice, it prevents overpayments, duplicate payments, and fraud, while improving accuracy in inventory and expense records.
