An engagement letter, commonly referred to as a letter of engagement, is a document used by auditors to delineate clearly the scope of their responsibilities in an audit engagement. It serves as the written confirmation of the auditors' acceptance of the appointment, the scope of the audit, the form of the report, and includes any non-audit services to be rendered.
A letter of engagement is a formal agreement between a professional service provider and a client outlining the terms and conditions of the service engagement.
