Accountancy pricing structures: what to ask about

Choosing an accountant often means comparing proposals that are structured in different ways, with fees that may not cover exactly the same services. The way an accountancy firm charges can affect what you pay over time, what is included and how easy it is to budget. Knowing the main pricing structures and what to ask can help you compare fairly and avoid surprises later.

Understand the main pricing structures

Accountants in the UK usually offer one or more of four pricing structures. Each suits different needs, so think about how much support you want and how predictable you want costs to be.

• Fixed annual fee: You pay a set amount for the year, covering an agreed package of services. This suits people who want certainty about cost and a clear scope of work. It is often used for self-assessment tax returns, company accounts or smaller businesses with straightforward needs.
• Monthly package: A regular monthly payment covers ongoing services. This can suit businesses with regular bookkeeping, payroll or VAT returns, as it spreads costs and sometimes includes cloud accounting software. It is worth checking exactly what the monthly fee covers and whether there are limits (such as number of transactions or payslips).
• Hourly rate: You are billed for the actual time spent on your work. This is sometimes used for ad-hoc advice, one-off projects or where the scope is not clear at the start. Costs can be unpredictable, so ask for an estimate of hours needed and what is likely to push it up.
• Per-service fee: Each task (for example, filing a tax return or preparing annual accounts) is priced separately. This gives transparency about what each job costs, but you will need to add up recurring and one-off services to see the total picture. It suits people with only a few requirements or those who want to keep control over what they use.

What is usually included and what may cost extra

No two accountancy packages are identical. Even if the headline looks similar, the details often differ. Here are typical inclusions and extras to look for when comparing proposals:

• Standard inclusions: A fixed fee or package usually covers routine annual work—such as preparing and filing accounts, basic tax returns, and possibly simple Companies House filings. Some may include access to a software package for bookkeeping, or a set number of advisory calls.
• Likely extras: Many accountants charge extra for anything outside the core package. Common add-ons include:
• Additional tax returns (for example, directors, property income, or capital gains)
• Handling HMRC enquiries or investigations
• Bookkeeping or payroll beyond a set limit
• Cloud accounting software subscriptions (sometimes included, sometimes not)
• Regular management accounts or business advisory calls
• Catch-up work if your records are behind
• Advisory services: Calls or meetings about business planning, tax advice or restructuring are often billed separately or included only up to a limit. Ask what level of support is included and what counts as extra.

Always ask for a full breakdown of what is included for the quoted fee, and get clarity on anything that is marked as an optional extra. The more detail you have, the fewer surprises you will face down the line.

Key questions about fee changes, onboarding and leaving

Before you commit, there are several practical questions to put to every accountant you are considering:

• How and when can the fee increase? Ask whether the quoted fee is fixed for a year, subject to review after a period, or could change if your business grows. A good accountant will explain in what circumstances fees might rise and how much notice you will get.
• Are there onboarding or setup fees? Some firms charge for initial setup, migrating records or registering you with HMRC. Others include this in the package. Clarify what, if anything, you will pay before regular work begins.
• What happens if my records are behind? Catching up on late or missing records is often charged at an hourly rate or as a one-off fee. Ask for an estimate so you know what to expect if you are not up to date.
• What does leaving cost? If you want to change accountants, check if there are exit fees or charges for transferring your files. Most firms will cooperate with handover, but it is helpful to know the process and any costs before you start.

Write down the answers from each firm. If you speak to several, you can compare not only the actual fees but also how clear and helpful each one is in their responses.

Comparing proposals: build your own service checklist

Because each accountant may group services differently, direct price comparisons are difficult unless you break down what you need and what is included. Building your own comparison table can clarify the total value:

1. List the services you require: For example, annual accounts, self-assessment, VAT returns, payroll, bookkeeping, advice, software access, HMRC correspondence.
2. Create a table: List each firm across the top and services down the side.
3. Tick off what is included, extra or not offered: Mark which services are included in each proposal, which are available as add-ons (and at what fee, if quoted), and which are not provided at all.
4. Add notes on limits or conditions: For example, number of transactions or calls included, or thresholds above which extra fees apply.

This method helps you compare proposals on a like-for-like basis. A firm with a lower headline fee may actually cost more once you include all the extras you need. You can find tips on comparing proposals in how to compare quotes fairly.

Annuvell Local makes it easy to request quotes from several accountants at once, sharing the same needs description. This helps you receive proposals that are easier to line up side by side.

The engagement letter: your reference for what is covered

Once you choose an accountant, you will receive an engagement letter. This is the formal document that sets out:

• The exact services to be provided
• The fees, payment terms and how changes are handled
• What is included and what counts as extra
• The responsibilities of both you and the accountant

The engagement letter is your reference point if you ever need to check what has been agreed. If anything is unclear, ask for clarification before you sign or pay anything. Do not rely on verbal promises or sales materials; only what is in the engagement letter is binding.

If you ever need to query a future invoice or service, the engagement letter is the first document to check. Keep a copy somewhere you can find it easily.
