When it comes to formalising client relationships and outlining the scope of services, accountants, tax advisors, bookkeepers, and accountancy firms often utilise two key documents: engagement letter vs proposal. Both are essential tools, but they serve different purposes and are used in distinct scenarios.
In this article, we will explore the differences between engagement letters and proposals, their roles, and why using specialised software like FigsFlow can enhance their effectiveness.
What Is an Engagement Letter?
Engagement letters are formal agreements that establish the terms and conditions of the relationship between the service provider and the client. They detail the scope of work, fees, responsibilities, and other pertinent details. The primary purpose of an engagement letter is to formalise the agreement between parties and outline specific services. They are often used when the scope of work is clear and agreed upon. Typically, an engagement letter includes a service description, duration, fees, client responsibilities, and legal terms.
For example, a bookkeeping engagement letter details the bookkeeping services provided and associated fees. An engagement letter for accounting services specifies the accounting services to be performed. Meanwhile, an audit engagement letter outlines the audit services and the terms under which they will be conducted. An engagement letter for consulting services describes the consulting services, scope, and fees.
What Is a Proposal?
Proposals are documents presented to potential clients outlining the proposed services, methodologies, and pricing. They are often used to win new business or to suggest additional services to existing clients. The primary purpose of a proposal is to persuade a potential client to choose your services over competitors. Proposals are used during the bidding process or when offering new services. A proposal typically includes an overview of services, methodologies, timelines, pricing, and benefits.
For instance, proposals for accountants outline accounting services, methodologies, and pricing to attract new clients. Similarly, proposal drafting for tax advisors describes tax advisory services and proposed solutions.
Engagement Letter VS Proposal
Understanding engagement letter vs proposal is crucial for accountants, tax advisors, bookkeepers, and accountancy firms. Engagement letters formalise the agreement, whereas proposals aim to secure new business.
Engagement letters are used after the client agrees to the services, while proposals are used before securing the client’s agreement. Additionally, engagement letters contain specific terms and conditions, while proposals contain persuasive content to win business.
When to Use an Engagement Letter vs a Proposal
Knowing which document to use is just as important as knowing how to draft it well. Sending the wrong document at the wrong stage can confuse clients, create legal gaps, or make your firm appear disorganized. The distinction comes down to where you are in the client relationship.
Here is a quick reference to help you decide:
As a general rule, proposals open the door and engagement letters close it. Once a client says yes, the proposal has done its job and the engagement letter takes over.
Best Practices for Drafting Engagement Letters and Proposals
To ensure that your engagement letters and proposals are effective, consider these best practices:
- Clarity and Detail – Clearly outline the services, terms, and conditions.
- Customisation – Tailor the document to the specific needs of the client.
- Professional Tone – Maintain a professional tone and structure.
- Compliance – Ensure compliance with relevant regulations and standards.
Common Mistakes to Avoid When Drafting Engagement Letters and Proposals
Even experienced accountants and tax advisers make avoidable errors when drafting these documents, often creating confusion, disputes, or compliance gaps that damage client relationships before they even begin.
Here are five mistakes worth watching for:
-
Using vague language around scope of work
Ambiguous descriptions like "general accounting support" invite scope creep and billing disputes. Define every deliverable, deadline, and exclusion explicitly so both parties share the same expectations from day one.
-
Skipping client-specific customisation
Copying a generic template without tailoring it to the client's situation signals a lack of care. Clients notice when documents feel recycled, and it weakens the professional impression you worked hard to create.
-
Omitting clear fee and payment terms
Leaving fee structures open to interpretation is one of the most common sources of conflict. Specify your fees, billing frequency, late payment terms, and any conditions that could trigger additional charges.
-
Confusing proposals with engagement letters

Engagement letters in particular must align with professional body requirements and relevant regulations. Skipping this review risks non-compliance, especially as rules around AML, MTD, and client identification continue to evolve.
