It is essential that a small business owner understands the level of involvement needed in their accounting to maintain sound finances and make successful business decisions.
In this guide, we will walk you through the various aspects of accounting for small businesses. From basic needs to potential costs, we will help you make informed decisions.
Every small business has unique accounting needs, but some basic requirements are universal. These include:
While it might be tempting to handle accounting tasks yourself, professional accountants can provide expertise and save you time and potential errors.
Professional accountants ensure that your financial records are accurate and compliant with legal standards, which is critical for avoiding penalties and making sound business decisions.
The size and complexity of your business play a significant role in determining your accounting costs. A larger business with multiple revenue streams, numerous transactions, and a sizable workforce will naturally incur higher accounting expenses than a smaller, simpler operation.
Different accounting services come with different business costs. Basic bookkeeping is usually less expensive than comprehensive financial planning or tax advisory services. Understanding what services you need can help you budget more effectively.
How often you require accounting services also affects the cost. Regular, ongoing services such as monthly bookkeeping or quarterly tax filings will cost more than one-off services like annual tax preparation.
You have two primary options for managing your small business accounting: hiring an in-house accountant or outsourcing to an accounting firm. Each has its own cost implications.
| Expense Type | In-House Accounting | Outsourced Accounting |
| Salary | NZD 70,000 – NZD 100,000 per year | N/A |
| Benefits | NZD 10,000 – NZD 20,000 per year | N/A |
| Training and Software | NZD 1,500 – NZD 5,000 per year | N/A |
| Hourly Rates | N/A | NZD 150 – NZD 400 per hour |
| Monthly Retainers | N/A | NZD 700 – NZD 4,000 per month |
| One-Time Setup Fees | NZD 500 – NZD 2,000 | NZD 500 – NZD 2,000 |
| Total Annual Cost | NZD 81,500 – NZD 125,000 (including benefits) | NZD 8,400 – NZD 48,000 (depending on service) |

Proper accounting helps you track your income and expenses, providing a clear picture of your financial health. This information is crucial for making informed business decisions and planning for the future.
Professional accounting ensures that your business complies with tax regulations, reducing the risk of penalties and audits. Accurate tax preparation and filing can also help you take advantage of tax deductions and credits.
Hiring a professional accountant saves you time, allowing you to focus on running your business. While there are costs involved, the efficiency and expertise they bring can ultimately save you money by preventing costly mistakes and ensuring optimal financial management.
Accurate financial records and expert advice from professional accountants can support your business growth. By understanding your financial position, you can make strategic decisions about investments, expansions, and other growth opportunities.
Accounting is a critical component of running a successful small business. By understanding your small business accounting needs, setting a realistic budget, and choosing the right services, you can ensure that your business remains financially healthy and compliant with all regulations.
Whether you opt for in-house accounting or Professional Accountants, the key is to invest in quality services that support your business’s growth and stability.

So how much should you actually be spending on accounting. I reckon the bit about understanding your unique needs first is dead right. Too many small biz owners just guess a number or go with whatever’s cheapest, then wonder why their finances are a mess. You gotta know what you actually need before you can budget for it. Spending the time upfront to figure that out saves heaps of grief down the line.
Reuben W. says:
Most small business owners spend way too much on accounting because they never actually map out what they need. They panic, throw money at it, then realise half of it’s wasted on services they’ll never use. The upfront work of figuring out your cash flow patterns, tax obligations, and reporting needs is the difference between smart spending and just bleeding cash every month.
DrRob says:
Nah, the bit about knowing your actual needs before spending a dollar is the only thing that matters here. Too many blokes skip that step entirely and end up paying for services they’ll never use.
Sophie M. says:
The bit about guessing a number really stuck with me because I’ve watched small biz owners throw money at accounting software they never use, then skip the actual bookkeeper who’d save them thousands in tax. Feels like the real trap is spending on the wrong things rather than spending too little overall. How do you figure out which type of accounting support actually moves the needle for your specific business model.

The bit about not going with cheapest first is crucial. See it all the time with small ops that pick a $50/month tool, realise six months in it can’t handle their GST or multi-entity stuff, then have to migrate everything. That cost of switching far outweighs what they’d have spent getting the right setup from day one.
