Who can sign for a business?

An authorized officer, manager, or other person with delegated authority should sign. Verify corporate authority by checking bylaws, operating agreements, or a board resolution when authority is unclear.

Do proposals require notarization or witnesses?

Most CPA proposals do not require notarization or witnesses. If a specific document attached to the proposal requires notarization, follow state notary and RON rules that apply to that document.

How to amend an executed proposal?

Create a written amendment referencing the original effective date, describe changes, obtain signatures from the same authorized parties, and archive the amendment with the original engagement file.

How long should I retain signed proposals?

Keep proposals for at least three years from filing for tax records (IRC §6501(a)) and longer if the engagement involves HIPAA or potential litigation; consult retention policies.

What if a signer cannot access the eSignature platform?

Offer alternative authentication methods such as SMS code, provide a printable copy for wet signature if required, or use an alternative compliant e-signature method to avoid execution delays.

What a Business CPA Proposal Is and how it functions

A Business CPA Proposal is a formal engagement document that sets out the services a certified public accountant will provide a business client, including scope, deliverables, timing, fees, payment terms, and responsibilities. It often incorporates an engagement letter, confidentiality provisions, conflict disclosures, and acceptance instructions so both parties understand expectations. When executed by authorized signatories it forms the basis for client billing and recordkeeping. Electronic execution with an audit trail aligns with U.S. e-signature frameworks and preserves evidentiary value for compliance and tax purposes.

Why a clear, documented proposal matters for CPAs and clients

A well-crafted proposal reduces scope disputes, clarifies fees, and documents client consent to accounting services. It creates an auditable record for compliance, supports accurate billing, and establishes timing for deliverables under applicable law, including ESIGN and UETA where electronic execution is used.

Who typically prepares and signs a Business CPA Proposal

Typical preparers and signers include firm partners, engagement managers, and business owners or authorized officers who accept the engagement.

CPA firm partners and managers responsible for client engagements and scope definition.
Business owners, CEOs, CFOs, or other officers authorized to bind the company to professional services.
In-house legal or procurement teams when larger contracts or negotiated terms require review.

Identifying the correct signatory role up front prevents execution delays and ensures obligations attach to the proper legal entity.

Core sections every professional Business CPA Proposal should include

A standardized proposal improves clarity and reduces negotiation time; the following six elements form a complete engagement document for most business clients.

Engagement Scope

Describe specific services (tax prep, bookkeeping, advisory), tasks excluded, and any deliverables. Clear scope limits disputes and defines success criteria for the engagement.

Fee Schedule

State fixed fees, hourly rates, milestone billing, and expense reimbursement rules. Include payment due dates, late fees, and any retainers or deposits required before work begins.

Timeline

List project milestones, delivery dates, and client responsibilities for providing data. Tie timeline items to payment triggers and acceptance criteria to avoid scope creep.

Data Security

Declare handling of client data, encryption, access controls, and any required HIPAA or privacy addenda when health or sensitive information is involved.

Terms & Conditions

Include limitation of liability, indemnities, dispute resolution, termination rights, and governing law to manage legal risk and set contractual boundaries.

Acceptance & Signatures

Provide a signature block for authorized signers, effective date field, and instruction for electronic signature methods accepted by the firm and client.

Step-by-step: completing and issuing the proposal

Follow these steps to prepare, review, and execute a Business CPA Proposal efficiently and consistently.
