What do accountants do? The core role

An accountant is a financial professional who manages, analyses, and reports on your business finances. They ensure your records are accurate, your taxes are filed correctly, and your business stays compliant with regulations.

Core accountant responsibilities include:

• Financial record-keeping: maintaining accurate books and transaction records
• Tax preparation and filing: completing returns and meeting deadlines for HM Revenue and Customs (HMRC), the UK's non-ministerial department for tax collection
• Financial reporting: producing profit and loss statements, balance sheets, and cash flow reports
• Compliance: ensuring your business meets legal and regulatory requirements
• Payroll processing: calculating wages, tax, and National Insurance contributions

These are the fundamentals. But modern accountants, especially those working with small businesses, offer much more than basic compliance work.

Types of accountants for small businesses

Different types of accountants specialise in different areas. Understanding the options helps you find the right fit for your business needs.

• Tax accountants: focus on tax planning, compliance, and dealings with HMRC
• Management accountants: provide strategic advice, budgeting, and performance analysis
• Financial accountants: prepare financial statements and ensure accurate reporting
• Public practice accountants: work in accounting firms serving multiple business clients
• In-house accountants: work as employees within a single company

Most small businesses work with public practice accountants who offer a mix of tax, compliance, and advisory services. As your business grows, you might add specialists for specific needs.

What can accountants do for your small business?

Accountants offer far more than number-crunching. They provide strategic advice, find ways to save money, and help boost revenue. They also automate administrative tasks so you can focus on your core business.

With the right accountant, you'll run your business with more clarity and confidence. Here's what they can do for you.

1. Master your tax obligations

A great accountant does far more than file your tax returns. They take a proactive approach to managing your tax position throughout the year.

A skilled accountant will:

• reduce your tax exposure through legitimate planning
• resolve old tax debts with HMRC
• fix poor record-keeping before it causes problems, especially as regulations require many businesses and individuals to keep digital accounting records and submit quarterly updates to HMRC
• help you avoid triggering audits
• ensure your books are watertight if you are audited

2. Launch a startup

An accountant helps turn your business idea into a funded reality. Many accountants are uniquely positioned to help with startups. A recent ACCA survey shows nearly half of women finance professionals aspire to become entrepreneurs, giving them firsthand insight into the startup journey.

Starting up takes more than a good concept. You need to prove it will make money and convince lenders to back you.

An accountant supports your startup by:

• testing your idea for financial viability
• identifying startup and operating costs
• creating credible revenue forecasts
• connecting you with the right lenders
• refining your pitch to impress investors

3. Help with business strategy

Accountants help you focus on what matters most for growth. With so many moving parts in a business, it's hard to know where to direct your energy.

Your accountant will work with you to set personal, professional, and financial goals. They'll give you tools to measure progress, including key performance indicators (KPIs) that show how your business is performing.

If you use accounting software, your accountant can set up dashboards to check your KPIs anytime. When things aren't going to plan, they'll troubleshoot issues, test solutions, and reset your targets.

4. Fix your cash flow

Accountants help you avoid running out of money at the wrong time. Many profitable businesses fail because they can't pay suppliers or staff when cash is tight. Even a busy business won't survive if payments come in slowly or spending runs too high.

Your accountant understands that revenue and costs fluctuate. They'll predict the effect on cash flow, organise reserves, and create a spending plan that keeps money in the bank. The result: less stress on payday, smoother supplier relationships, and better sleep.

5. Listen and support you

A good accountant provides moral support when business gets tough. They may also direct you to professional bodies that offer free, confidential support.

Running a business can be lonely. When challenges feel overwhelming, your accountant can keep you focused and moving forward.

They understand how much your business means to you. They'll break down big problems into manageable parts, help you cope with stress, and reassure you on your journey.

6. Manage your debt

Accountants help you use debt strategically to grow your business. There's good debt (investment that generates returns) and bad debt (borrowing that drains resources). Your accountant helps you tell one from the other.

They'll find borrowing strategies with the right mix of flexibility and low interest. If you need refinancing, they'll handle that too.

Your accountant also advises when spare cash should pay back loans versus being reinvested. They'll analyse your numbers and debt structure to develop a strategy tailored to your situation.

7. Deal with unpaid invoices

Accountants take the headache out of chasing unpaid invoices. Late payments are a fact of business, but chasing debtors distracts you from more important work.

Your accountant can help by:

• setting up invoice systems with automatic payment reminders
• following up with customers who don't respond to emails
• arranging invoice financing, where a third party buys your unpaid invoices and collects payment for you

8. Write and pitch loan applications

Accountants help you secure funding by crafting compelling loan applications. Applying for a loan is both an art and a science. A good accountant does more than pull together numbers. They help you tell a story that resonates with lenders.

Lenders need solid financials and credible forecasts, but that's just the start. Your accountant will create a presentation that sells the wider vision for your business.

Instead of spreadsheets, you'll have graphs and charts that visualise the opportunity. They'll use forecasting tools that loan officers trust.

9. Budget smartly

Accountants create accurate budgets that give you real confidence. Detailed budgeting takes time and energy. Without help, many businesses work from vague numbers full of assumptions.

A rigorous budget from your accountant shows you:

• the real cost of doing business
• how much money you can reinvest
• what you can pay yourself

10. Help with hiring and payroll

Accountants help you hire the right people and manage payroll correctly. If you need staff but aren't sure where to start, your accountant can guide you through the process.

They support your hiring by:

• identifying which type of hire will boost your business most
• calculating the full cost of hiring, training, and paying an employee
• setting up compliant payroll, including tax, insurance, and government paperwork

11. Set up your cloud accounting software

Accountants set up cloud accounting software that automates your financial admin. Your accountant can connect your systems so sales and expense data flows directly into your accounts. They'll configure invoicing that tracks what's been paid and sends automatic reminders to late payers.

Other automated systems they can set up include:

• Cash flow dashboards: see your financial position at a glance
• KPI tracking: check business performance around the clock
• Automated accounts payable: stay on top of expenses effortlessly
• Mobile accounting apps: manage finances from anywhere

12. Help you manage stock

Accountants help you manage stock more efficiently and reduce waste. Poor stock management costs money through excess storage, obsolete goods, and lost sales from running out of popular items.

Your accountant can help by:

• identifying the true cost of holding stock
• reviewing sales data to predict demand accurately
• setting up software that tracks levels and auto-orders when stock runs low

13. Improve your business efficiency

Accountants identify unnecessary costs and improve your operational efficiency. Business costs can climb quickly across storage, energy, IT, and staffing.

If you don't have time to analyse these expenses strategically, your accountant can do it for you. They'll spot inefficiencies and help you develop more cost-effective ways of working.

14. Unlock the power of technology

Accountants connect you with technology that automates manual tasks. Smart business software can handle many things you currently do by hand. A tech-savvy accountant can set up affordable tools for:

• staff scheduling and time recording
• point of sale
• taking payments
• customer relationship management
• invoicing
• payroll

Automating these processes reduces admin pain, lowers costs, and keeps everything running smoothly. Look for an accountant who understands business apps and can recommend the right solutions.

15. Build a personal relationship with you

Modern accountants build genuine relationships with their clients. Today's accountants take a more personal, approachable style. Many have interesting backgrounds and will visit your workplace to understand how your business actually operates.

Finding an accountant you connect with personally and professionally can make all the difference to how you run your business.

When should you hire an accountant?

Hire an accountant when the cost of mistakes or missed opportunities outweighs their fees. There's no single right moment, but certain situations signal it's time to get professional help.

Consider hiring an accountant when you:

• earn more than £25,000 annually and tax complexity increases
• spend more than a few hours each week on bookkeeping
• plan to apply for funding or loans
• want to grow but aren't sure your finances can support it
• face a tax investigation or compliance issue
• hire employees and need to manage payroll

You can bring in an accountant at any time. Many business owners find that bringing in an accountant earlier saves money in the long run through better planning and fewer costly mistakes.

What to look for in an accountant

Look for an accountant who combines the right qualifications with a good personal fit. Technical skills matter, but so does communication style and understanding of your business.

Key qualities to evaluate:

• Relevant qualifications: look for Association of Chartered Certified Accountants (ACCA), Chartered Institute of Management Accountants (CIMA), Associate Chartered Accountant (ACA), or Institute of Chartered Accountants in England and Wales (ICAEW) certification, a globally recognised body with over 172,273 members in 150 countries
• Small business experience: they should understand the challenges you face
• Industry knowledge: experience in your sector helps them give relevant advice
• Technology proficiency: familiarity with cloud software like Xero speeds up collaboration
• Clear communication: they should explain financial concepts in plain language
• Transparent fees: understand their pricing structure before you commit
• Advisory mindset: the best accountants offer strategic guidance, not just compliance
• Availability: check how responsive they'll be when you have questions

Meet potential accountants before deciding. The relationship works best when you feel comfortable asking questions and discussing challenges openly.

FAQs on working with accountants

Here are answers to common questions small business owners have about hiring and working with accountants.

How much does an accountant cost for a small business?

Small business accountants in the UK typically charge £500–£3,000 per year, depending on your business complexity and the services you need. Some charge hourly rates (£25–£150), while others offer monthly retainers or fixed-fee packages. The value they provide by saving you tax and freeing up your time often outweighs their cost.

What's the difference between an accountant and a bookkeeper?

Bookkeepers handle day-to-day transaction recording, bank reconciliation, and basic financial reports. Accountants provide higher-level services including tax planning, strategic advice, compliance, and financial analysis. Many small businesses use both, with a bookkeeper managing routine tasks and an accountant handling complex matters.

When should I hire an accountant for my small business?

Consider hiring an accountant when you earn more than £25,000 annually, spend significant time on financial admin, plan to seek funding, or face growing tax complexity. Many business owners benefit from getting an accountant early to support their growth from the start.

Do I need an accountant if I use accounting software like Xero?

Yes, software and accountants work best together. Accounting software handles data entry, automation, and real-time reporting. Your accountant interprets that data, provides strategic advice, ensures compliance, and optimises your tax position. Xero-certified accountants can maximise the value you get from both.

How do I know if my accountant is doing a good job?

Signs of a good accountant include proactive communication and strategic recommendations beyond basic compliance. They should clearly explain your financial position, respond quickly to questions, and keep you penalty-free with HMRC. A great accountant stays in touch throughout the year to provide valuable advisory support.
