Vendor reconciliation is an accounts payable control procedure used to verify that vendor statements match the organization's accounts payable records. This process helps accounting teams identify missing invoices, duplicate entries, payment discrepancies, and outstanding vendor balances. Without a standardized reconciliation process, organizations risk inaccurate liabilities, unresolved vendor disputes, and financial reporting errors. This page provides a vendor reconciliation standard operating procedure (SOP) used by finance teams to document the reconciliation workflow.
Many companies document reconciliation workflows using SOP management software such as ProcessDeck, allowing accounting teams to standardize processes, assign responsibilities, and track execution. Vendor reconciliation typically follows the vendor invoice processing workflow and the vendor payment processing procedure used by accounts payable teams. Learn how organizations structure process documentation.

A structured reconciliation procedure helps organizations:
Understand how organizations preserve operational knowledge through knowledge transfer.
Before starting vendor reconciliation, the following information must be available.
Most of this information originates from earlier AP workflows such as the vendor invoice processing procedure used by accounts payable teams.
