Scope of Services
A precise description of tasks, deliverables, and any exclusions so the CPA's responsibilities are limited to agreed work and assumptions are reduced.
A well-drafted CPA Engagement Agreement protects both client and CPA by documenting scope, responsibilities, fees, and limitations. It reduces the risk of misunderstandings, supports fee collection, and helps limit professional liability. For electronic execution, ESIGN (15 U.S.C. §7001) and state UETA laws provide enforceability when intent, consent, attribution, and retention requirements are met.
Typical users include individual practitioners, accounting firms, and the clients who engage them.
The document is suitable for recurring services or one-time engagements and should be tailored to risk, industry, and regulatory requirements.
