How to Choose the Right Accounting Firm for Your Business

An accountant can become an important part of your business support network, rather than simply the person who prepares your accounts once a year.

ICAEW advises small businesses to consider more than basic charges when choosing an accountant. It recommends discussing the scope of your needs, communication frequency and turnaround times during the initial consultation.

This matters because accounting firms can offer very different levels of service.

One firm may only prepare annual accounts and tax returns. Another may provide bookkeeping, payroll, VAT, management accounts, forecasting and business planning.

The cheapest option may therefore not be the best fit. The better question is whether the firm provides the services, expertise and support your business actually needs.

10 Things to Consider When Choosing an Accounting Firm

Choosing an accounting firm involves more than comparing prices. The firm’s qualifications, experience, services and approach to client support can all affect the value you receive. Use these 10 factors to compare your options and identify a firm that fits both your current needs and future plans.

1. Check Their Qualifications and Professional Membership

A good starting point is to establish whether the firm has the professional credentials and experience you would expect from an accounting provider.

Look at its qualifications, experience and professional body membership. Professional organisations such as ICAEW and ACCA provide directories that allow businesses to check firms and members.

ICAEW recommends looking for an accountant with a professional qualification and explains that appointing an ICAEW Chartered Accountant or regulated firm provides qualified and accountable professional support.

You can also search the official ICAEW directory for a chartered accountant or firm by location and specialist area.

ACCA also provides a directory of accountancy firms. Its guidance explains that businesses should check a firm’s certificates to understand whether it is regulated by ACCA for specific activities.

This does not mean you have to choose a firm from one particular professional body. It means you should verify the firm’s credentials and understand what those credentials cover.

2. Look for Experience in Your Industry

Professional qualifications are important, but an accountant also needs to understand the commercial realities of your business.

Different businesses face different financial and tax issues. A construction company may have different VAT and subcontractor requirements from a consultancy. An online retailer may need help with stock, payment platforms and international sales.

Ask whether the accounting firm already works with businesses similar to yours.

You can ask:

• Do you work with businesses in my industry?
• Do you understand my business structure?
• Have you supported businesses at a similar stage?
• Can you help if the business expands?
• What financial or tax issues do businesses like mine usually face?

Industry experience can help an accountant understand your problems faster and provide advice that is more relevant to your business.

3. Compare the Accountancy Services You Need

Before comparing fees, make sure you understand what support your business actually needs.

Common accountancy services include:

• Bookkeeping
• Annual accounts
• Self Assessment
• Corporation Tax
• VAT returns
• Payroll
• Management accounts
• Cash flow forecasting
• Budgeting
• Tax planning
• Financial forecasting
• Business planning

However, not every accounting firm provides all of these services.

Ask each firm for a clear list of what is included in its package and what would cost extra.

This can also prevent you from having to change accountants later because the firm cannot provide a service your growing business needs.

4. Ask How They Handle Digital Accounting

Technology should also be part of your decision when comparing accounting firms.

Cloud accounting software can make it easier for you and your accountant to access financial records, keep information up to date and work together.

This is becoming more important as Making Tax Digital expands.

From 6 April 2026, sole traders and landlords with qualifying income above £50,000 have had to use Making Tax Digital for Income Tax. The threshold falls to more than £30,000 from April 2027 and more than £20,000 from April 2028.

Businesses within the rules need compatible software to keep digital records and send quarterly updates to HMRC.

Therefore, ask a potential accounting firm:

• Which accounting software do you use?
• Is the software compatible with Making Tax Digital?
• Can you help me move from spreadsheets to accounting software?
• Will you manage my digital records or will I?
• Can I access my accounts and reports?

A good firm should be able to explain the process clearly rather than simply telling you which software to buy.

5. Find Out Who Will Manage Your Account

This is easy to overlook, but it can have a significant impact on your experience with the firm.

You may meet a partner or senior accountant during the sales process but later deal mainly with another member of the team.

Ask who your main contact will be and how the relationship will work.

You should know:

• Who prepares your accounts?
• Who reviews the work?
• Who answers tax questions?
• Can you speak directly to a qualified accountant?
• How quickly does the firm usually respond?

ICAEW highlights communication frequency and turnaround time as matters worth discussing during your initial consultation.

A firm can have excellent technical skills but still be frustrating to work with if you cannot get a response when you need one.

6. Compare Fees and What Is Included

Once you understand the level of support you need, you can compare fees more fairly.

Price matters, but it should not be the only thing you compare.

Two accounting firms may quote very different fees because they offer different levels of service.

For example, one quote may cover annual accounts and Corporation Tax only. Another may include bookkeeping, VAT returns, payroll and regular management reports.

Ask each firm to explain:

• The total fee
• What accountancy services are included
• What is charged separately
• Whether fees are fixed or based on time
• Whether there are setup costs
• How often you will be billed
• What happens if your business needs change

A clear fee structure makes it easier to compare firms fairly.

7. Ask What Business Advice They Provide

Your accountant should be able to help you understand your numbers, not simply record them.

Ask whether the firm provides advice on cash flow, margins, budgeting, tax planning and business growth.

This can become more valuable as your business develops.

A growing business may need an accountant who can help assess whether it can afford to hire staff, invest in equipment, take on finance or expand into a new market.

That is why it is worth asking what happens after the accounts have been prepared.

Will the firm explain what the numbers mean and highlight issues that need your attention?

For a growing business, this kind of financial insight can be just as valuable as getting the compliance work completed.

8. Check Their Approach to HMRC and Tax Matters

Tax support is another area where it is useful to understand exactly what an accounting firm will handle for you.

If your accountant acts as your tax agent, you may authorise them to deal with HMRC on your behalf.

HMRC’s current guidance explains that authorised agents can perform different tasks depending on the tax service involved, including dealing with Self Assessment and VAT matters.

Before giving authority, make sure you understand what the accounting firm will handle for you.

You should also ask how the firm deals with tax enquiries, late filings and changes to your circumstances.

A professional accountant should be able to explain your responsibilities as well as their own.

9. Check Their Reputation and Client Reviews

Once you have narrowed down your options, it is worth looking at what existing or previous clients say about the firm.

Reviews can give you useful information about how a firm communicates and works with clients.

However, do not rely on reviews alone.

Look for client testimonials, professional memberships, years of experience and evidence of the firm’s work. You can also ask for references or speak to another business owner who uses the firm.

ICAEW recommends asking colleagues and friends for recommendations when looking for an accountant.

Pay attention to recurring comments about communication, accuracy, responsiveness and the quality of advice.

10. Think About Your Future Needs

Finally, consider whether the firm can continue to support you as your business changes.

The accounting firm you choose today may still be working with you several years from now.

Your business could move from sole trader to limited company. You may take on employees, register for VAT, need management accounts or start planning for expansion.

Therefore, ask the firm how it supports growing businesses.

A useful question is:

‘If my business doubles in size over the next few years, how could your services change with it?’

The answer can tell you whether the firm is thinking about a long-term relationship or simply the immediate compliance work.
