Key takeaways

• Recognize when to bring in professional help: if you're spending more than 10 hours a week on financial tasks, facing tax complexity, or planning for growth, hiring an accountant is likely to save you more money than it costs.
• Understand the difference between a bookkeeper and an accountant so you hire the right support: a bookkeeper manages your day-to-day records, while an accountant provides strategic advice on tax, business structure, and growth planning.
• Use accounting software and an accountant together rather than choosing one over the other, as software handles routine tasks like bank reconciliation and invoicing, while an accountant interprets complex tax rules and guides your business decisions.
• Prioritize getting accountant advice before making big business decisions, such as changing your legal structure or seeking funding, as the right guidance can protect your personal assets and improve your chances of securing investment.

What does an accountant do?

Before deciding whether you need an accountant, it helps to understand what they actually do for small businesses. Accountants look at the big picture of your business finances and apply their knowledge from years of mentored experience to help you make strategic decisions.

An accountant can help you with a range of important financial tasks:

• Prepare and file your annual tax returns
• Ensure you comply with government reporting requirements
• Advise on the best business structure for your situation
• Create financial forecasts and growth strategies
• Manage complex payroll and employee tax obligations

What does a bookkeeper do?

Bookkeepers and accountants both handle finances, but their roles are different. Understanding the distinction helps you hire the right support for your business.

While accountants focus on strategy and tax, bookkeepers manage your day-to-day financial records. They keep your accounts accurate and up to date so your accountant has clean data to work with.

A bookkeeper typically handles routine administrative tasks:

• Record daily transactions and receipts
• Reconcile bank accounts to match your software
• Send invoices and chase late payments
• Pay supplier bills on time
• Generate basic financial reports like profit and loss statements

Can accounting software replace an accountant?

Modern cloud accounting software automates many financial tasks, which raises an important question. You might wonder if you still need an accountant when software can do so much of the heavy lifting.

Accounting software handles routine work well. It automates bank reconciliation, generates invoices, and provides real-time data about your cash flow. This saves you hours of manual data entry and keeps your records organised.

However, software cannot replace human expertise. You still need an accountant to interpret complex tax rules, provide strategic business advice, and help you plan for growth. The best approach is to use accounting software to manage your daily tasks, and partner with an accountant for high-level guidance.

You're spending too much time on bookkeeping

Spending more than 10 hours a week on bookkeeping is a sign you need professional support. If your evenings and weekends go to reconciling accounts and chasing invoices, that time isn't going to growing your business.

You started your business to pursue a passion, not to get buried in paperwork. Businesses still spent a median of 32 hours in 2024 solely on in-house tax compliance.

A simple cost–benefit check can help you see when it pays to hire an accountant.

Here's what doing your own bookkeeping typically costs:

DIY costs:

• Time investment: 10+ hours for tax preparation alone
• Opportunity cost: nearly $1,000 in lost revenue when owners earning $96.39 per hour spend 10 hours on bookkeeping
• Error risk: exposure to penalties and corrections costing thousands

Hiring a professional offers these advantages:

Professional benefits:

• Lower hourly rates: costs less than your billable rate
• Revenue generation: more time to focus on business growth
• Risk reduction: fewer costly mistakes through expert handling

Make tax time easier

Tax compliance becomes straightforward when you have expert support. An accountant handles the rules, identifies deductions you can claim, and prepares you for audits.

For many business owners, tax season feels uncertain. If you're not confident with the numbers, professional help removes the guesswork.

8 in 10 businesses use accountants or bookkeepers to meet their tax responsibilities. Here's what they handle:

• Accuracy: checks to ensure your returns are correct before filing
• Timeliness: submits everything by the deadline
• Deductions: identifies claims you're entitled to

With an expert managing your tax obligations, you can focus on running your business and avoid costly errors.

You need advice about your company's legal structure

Your business structure affects liability, tax, and operational complexity. An accountant helps you choose the right option for your situation.

Operating as a sole trader has several advantages:

Sole trader benefits:

• Tax advantages: offset living expenses against business income
• Simple setup: minimal paperwork and compliance

However, there are also risks to consider:

Sole trader risks:

• Personal liability: your assets are exposed to business debts
• Limited credibility: reduced supplier and customer confidence

A limited company structure offers different advantages:

Limited company benefits:

• Asset protection: business debts separated from personal wealth
• Professional image: credibility with customers, lenders, and suppliers

An accountant assesses your specific situation and recommends the optimal structure for your goals.

Your cash flow is unpredictable

Unpredictable cash flow occurs when money moves in and out faster than you can track. It makes planning difficult, delays bill payments, and stalls growth investment.

When you're not sure where your money is going, it's hard to make confident business decisions.

An accountant provides a clear picture of your financial health. They help you:

• set up a budget that reflects your actual costs
• forecast your cash flow to anticipate shortfalls
• identify opportunities to improve profitability

With their guidance, you gain control over your finances and ensure your business has the funds it needs to thrive.

You've made costly financial mistakes

Costly financial mistakes include miscalculated tax liability, missed payment deadlines, and investments that didn't pay off. These errors drain cash flow and create unnecessary stress.

An accountant helps you correct past mistakes and put systems in place to prevent them recurring. Their expertise keeps your finances accurate, so you can move forward with confidence and protect your bottom line.

You're scaling and need a financial strategy

Growth creates financial complexity. As you hire staff, expand locations, or seek funding, you face bigger money decisions that require expert guidance.

An accountant helps you navigate this stage by:

• reviewing your profits to confirm you can afford expansion
• testing different growth scenarios before you commit
• preparing loan applications with credible financial projections
• managing payroll and employee tax as your team grows

Their advice helps you make clear, well-informed decisions about how and when to grow.

Growth doesn't always happen at a steady pace. A new client or big project can mean expanding faster than planned.

An accountant manages the day-to-day impacts of growth:

• Payroll: employee tax and wage processing online (around 41% of businesses outsource this, while more than half of businesses now rely on digital tools for these tasks)
• Overhead: property costs, bills, and new office expenses
• Analysis: cash flow, inventory stock levels, margins, and pricing reviews
• Timing: advice on when to introduce new products or services

If you're seeking funding, an accountant can prepare financial projections that investors expect, with realistic revenue forecasts and proven assumptions.

This support lets you focus on where you want the business to go, not the administrative detail of getting there.

How much does an accountant cost in NZ?

Understanding accountant fees helps you budget appropriately and evaluate whether the investment makes sense for your business. Costs vary widely depending on the size of your business and the level of support you need.

Many accountants now offer fixed monthly retainer packages rather than charging by the hour. This gives you certainty over your expenses and encourages you to ask questions without worrying about a surprise bill.

When evaluating the cost, consider the return on investment. A good accountant often saves you more money than they cost by identifying tax deductions, preventing expensive compliance errors, and freeing up your time to focus on sales.

You're ready to delegate financial tasks

Financial tasks are the ideal starting point for delegation because they're clearly defined and measurable, making them easier to hand over and review.

Many business owners struggle with handing over financial responsibilities. It can be hard to delegate when you:

• want to stay across every part of the business
• find it hard to trust someone new with your finances
• feel too busy to train someone properly

Despite these challenges, delegation brings real benefits. Delegating finances helps you:

• free up time to focus on strategic work and growing your business
• reduce stress by sharing the workload with qualified professionals
• improve accuracy through expert handling of complex tasks

Accountants can help every step of the way

Your speciality is running your business. Leave the financial details to an accountant. The right accountant should make life easier for you, so you can concentrate on what you love doing.

Through cloud-based accounting software, you'll be able to keep track of what your accountant does, and always be able to see your company's financial situation at a glance. Get connected with an experienced accountant in the Xero advisor directory.

FAQs on hiring an accountant

Here are answers to common questions about when and how to hire an accountant for your small business.

How do I know if I need an accountant or a bookkeeper?

When is the best time to hire an accountant?

The best time to hire an accountant is when you're spending more than 10 hours a week on financial tasks, facing tax complexity, planning for growth, or making important decisions about your business structure. You can also hire one before starting your business to set up properly from the beginning.

Can I afford an accountant if I'm just starting out?

Many accountants offer packages for startups and small businesses with flexible pricing. The cost often pays for itself through tax savings, avoided penalties, and the time you save. Start by getting quotes from a few accountants to understand the investment.

What should I look for when choosing an accountant?

Look for relevant qualifications, experience with businesses like yours, clear communication, and transparent pricing. Check if they use the same accounting software as you, and ask for references from current clients. A good accountant should understand your industry and business goals.
