Why start an online business

Here's what you need to know about getting started.

Starting an online business means launching a company that operates primarily through digital channels, whether selling products, offering services, or creating content. The process shares similarities with traditional business setup, but key differences include lower startup costs, different marketing approaches, and technology-dependent operations.

A survey of 171 accountants and bookkeepers who work with online businesses reveals what sets them apart. Their insights reveal three advantages: online business ideas can be more niche, business plans can be shorter, and startup budgets can be smaller.

Benefits of online business

The accountants and bookkeepers who completed this survey prepare financial statements for 6,000 small businesses across the US, the UK and Australia. Here's how online businesses compare to brick-and-mortar operations:

• Higher profitability: 57% say online businesses have better net profit margins
• Greater resilience: 67% say online businesses are less likely to fail, and 69% say owners lose less if they do
• More innovation: 63% say online businesses are more likely to be based on a novel idea
• Better lifestyle flexibility: Online business owners are twice as likely to hold down a day job as well
• Lower stress: Just 9% say online owners are more stressed, compared to 48% for brick-and-mortar owners
• Cheaper startup: Six in 10 say retail is cheaper to start online, and two-thirds say services are cheaper online
• Lower running costs: Seven in 10 say it costs less to run a small business online
• Faster break even: Seven in 10 say retailers break even sooner online, and five in 10 say the same for services

Challenges to expect

The experts also identified common challenges for online businesses:

• Digital marketing complexity: 35% say digital marketing is hard to figure out
• Technology learning curve: 32% say owners struggle to understand the tech
• Transaction fee surprises: 33% say online transaction fees catch people out
• Time demands: 29% say the hours spent on social media and reviews can be tough
• Website quality: 26% say businesses struggle to create a genuinely good website

The online and bricks-and-mortar businesses in this study had comparable revenue so these differences were not likely due to scale. The study included 171 accountants and bookkeepers, with an average of 35 clients each.

Find your online business idea

Once you understand the benefits, it's time to explore what type of business suits you.

Online business ideas fall into four broad categories:

• Retail and ecommerce: Selling physical products through your own website or marketplaces like Amazon or Facebook
• Service providers: Offering professional services like consulting, design, writing, or coaching remotely
• Digital products: Creating and selling downloadable products like courses, templates, or software
• Content and media: Building an audience through blogs, podcasts, or videos and earning through ads or sponsorships

Each model has different startup costs, time commitments, and skills required. Think about what fits your strengths and lifestyle.

See our guide on online business ideas for tips on what could work for you.

How to refine your idea

Online businesses cost less to start, but they demand just as much energy and effort as physical businesses. A little research upfront can help you refine your product or service and before you invest that time.

Business experts shared their top tips for online startups. The most common reply was to define your target market before you launch.

Your target customers might be local parents, fitness fanatics, restaurants, schools, or something else entirely. Once you know who they are:

• Design for them: Make your product or service perfect for that specific user
• Market to them: Pitch your messaging directly at their needs and interests
• Talk to them: Ask potential customers what they think of your idea, packaging, and price point
• Learn from them: Find out who they buy from now to understand your competitors' strengths and weaknesses

Validate your business idea

Before you invest serious time or money, test whether people will actually pay for what you're offering. Start small with a simple version of your product or service and see if you can get a few paying customers.

You can validate your idea by:

• Talking to potential customers about their problems and whether your solution helps
• Creating a simple landing page and seeing if people sign up for updates
• Offering a limited version of your product to a small group
• Running a small paid advertising test to see if people click and convert

This early feedback helps you refine your offering before you scale up. It's much cheaper to learn what works now than after you've built everything.

Choose your business structure

Before you can start selling, you need to decide on a legal structure for your business. This affects your tax obligations, liability, and how you can take money out of the business. In New Zealand, the two most common options for small businesses are sole trader and company.

Sole trader vs. company in New Zealand

As a sole trader, you are the business. It's the simplest and cheapest structure to set up, with less paperwork. However, you're personally responsible for all business debts.

A company is a separate legal entity from you, which protects your personal assets. It can look more professional but involves more setup costs and compliance tasks, such as the requirement to annually confirm that the information about your company on the Companies Register is correct and pay a fee.

Tax implications of each structure

Your business structure determines how you pay tax. Sole traders pay tax on business income through their personal tax return. Companies pay tax separately at the company tax rate, and you pay tax again on any money you take out as salary or dividends. Talk to an accountant about which structure makes sense for your situation and goals.

How your structure affects accounting

Your business structure determines your accounting and tax requirements; for example, if you become an employer, you'll be responsible for ensuring your KiwiSaver contribution rates are correct.

Sole traders have simpler tax obligations, often just filing an individual tax return with their business income included. Companies have more complex requirements, including filing a separate company tax return and keeping more detailed records. Choosing the right structure from the start makes managing your finances much easier.

Register your business and meet legal requirements

Once you've chosen a structure, it's time to make it official. Following the right steps ensures your business is compliant from day one and avoids problems later on. These are the key registration tasks for a new online business in New Zealand.

Register with the New Zealand Companies Office

If you've decided to operate as a company, you must register it with the New Zealand Companies Office. This is a crucial step for compliance. The registrar regularly publishes notices to remove 65 companies at a time for various infractions. This process includes reserving your company name. If you're a sole trader, you can trade under your own name without registering, but if you want to use a different name, you should check it's not already in use.

Get your IRD number and understand tax obligations

Your business will need a New Zealand Business Number (NZBN) and an IRD number for tax purposes. A company gets these automatically upon registration. Sole traders can use their personal IRD number but should register for an NZBN. Understanding your obligations for income tax and provisional tax is a crucial next step. It can also unlock benefits like the government's investment boost, which offers a 20% deduction for the cost of new business assets.

Register for GST if required

You must register for GST if your business earns over $60,000 in a 12-month period. You can also choose to register voluntarily if you earn less. Registering for GST means you charge GST on your sales and can claim back GST on your business expenses. It adds some admin work but can improve your cash flow.

Secure your domain name and business name

Your online address is vital. Check if your desired domain name (your website address) is available and secure it as soon as possible. It's a good idea to also check social media handles to ensure you can have a consistent brand name across all platforms.

Write your business plan

A solid plan helps guide your business decisions.

An ecommerce business plan outlines your online business strategy, but it doesn't need to be as detailed as traditional plans. Online startups often work with less certainty, so shorter, more flexible plans tend to work better.

Why you don't need a 20-page plan

Traditional 20-page business plans are designed to impress investors and lenders. But online startups typically cost less to launch, so you're less likely to need outside funding.

This frees you to write a plan that works for you. It might still be detailed, but it doesn't have to be.

Why you may only need a 1-page plan

Almost 60% of new online business owners struggle to forecast revenue for their first few months (Global Ecommerce Report, Xero 2019). That's because so much depends on digital marketing success, which takes experimentation to figure out.

You'll likely try multiple tactics across several platforms before you find what works. Only then will you have enough data to forecast sales accurately.

This is why online startups tend to use shorter, more fluid plans. A one-page plan that's easy to update works better than a rigid 20-page document.

What to include in your plan

Even a simple business plan should cover the essentials. Include a clear description of what you're selling and who you're selling to. Outline your pricing strategy and how you'll reach customers. Add a basic budget showing your startup costs and expected monthly expenses. Finally, set some goals for your first year, like revenue targets or customer numbers.

Shorter plans doesn't mean no plans

While the planning is dialled back a bit for online startups, it doesn't go away and nor should it. Working through the steps of a business plan will help you think about your startup from lots of different angles. That process will help you build on your idea and make it better.

Create your startup budget

Understanding your costs is essential for success.

A startup budget maps out your expected costs and helps you understand when your business might become profitable. While online businesses generally cost less to run than physical ones, beginners often overlook some significant expenses.

Common costs for online businesses

Typical expenses for an online business include:

• Website and hosting: Domain registration, website builder subscriptions, or developer fees
• Ecommerce platform fees: Monthly subscriptions and transaction fees for selling online
• Digital marketing: Advertising costs, email marketing tools, and social media promotion
• Software and tools: Accounting software, project management apps, and design tools
• Inventory or materials: If you're selling physical products, you'll need stock
• Professional services: Accountant fees, legal advice, or freelance help

Budgeting mistakes to avoid

New business owners often make the same budgeting errors. Here are three common budgeting mistakes to avoid:

• Underestimating website costs: 35% of experts say beginners overlook this. Templates are affordable, but creating a great user experience often requires freelance help
• Misjudging digital marketing spend: 37% say startups get caught out here. Cost-per-click advertising adds up quickly when only about one in 50 visitors convert to customers
• Forgetting transaction fees: 33% say this catches people out. Payment processors take up to 5% of each sale, which you need to factor into your pricing

How to do a budget

Here's how to create your startup budget:

1. List all your expected business costs
2. Plot them on a calendar so you know when each expense will hit
3. Add modest sales projections to the same calendar
4. Plan how you'll cover bills while revenue builds

You'll likely be in the red at first. Online business consultant Shahemen Farid of Boobooks Accountants recommends starting with three months of working capital and basing forecasts on that first quarter.

See our guide to startup business costs for a breakdown of typical expenses.

How to price your products or services

While online businesses are cheaper to run, customers don't expect them to pass those savings on. They can maintain prices similar to bricks-and-mortar competitors, which leaves them with more margin between buy and sell prices.

Some of that extra margin will end up paying for things like shipping, which most customers expect you to offer for free. But some will go into the business owner's pocket, with the study confirming that ecommerce businesses have higher net profit margins.

Fund your online business

Most online businesses start without outside investment.

Self-funding is the most common way to finance an online startup. Banks rarely back new online businesses unless you have a strong track record.

Self-funding your business

The good news is that many online businesses can launch affordably:

• Service businesses: Often start with just a laptop and a few software subscriptions, which founders can pay for out of pocket
• Retail businesses: Can begin with a soft launch and limited inventory, ramping up only when demand is proven

"You can start an online retail business for $20K now," says Shaheman Farid of Boobooks Accountants. "So people are increasingly able to self-finance."

Alternative funding sources

If you need extra money to start, consider these options:

• Credit cards: Quick access to funds, but interest rates are high
• Personal loans: Requires offering something you own as security
• Friends and family: They might lend cash or buy in as investors
• Angel investors: Industry contacts who believe in your idea may invest
• Crowdfunding: Works best for ideas with viral potential that excite a crowd
• Grants: Some cause-driven businesses qualify for free funding

Choose your platform and essential tools

The right technology makes running your business smoother and more efficient. Before you build your website, decide on the core platforms and tools that will power your operations, from selling products to managing your finances.

Ecommerce platforms compared

You have two main options for selling online: using existing marketplaces or building your own store.

Marketplaces (Amazon, Facebook, Trade Me)

• Pros: Fast setup, built-in payment processing, existing customer traffic
• Cons: Less control over branding, marketplace takes a cut of each sale

Your own online shop (Shopify, Square, BigCommerce)

• Pros: More flexibility over design and customer experience
• Cons: Monthly subscription fees, transaction fees, requires more setup effort

Build your shop with care. The extra flexibility of your own store comes with more potential for mistakes.

Accounting software for online businesses

From day one, you need a way to track your income and expenses. Good accounting software connects to your bank and ecommerce platform, automates invoicing, and gives you a real-time view of your cash flow. This makes it easier to manage your finances and prepare for tax time without relying on messy spreadsheets.

Accounting software like Xero connects with your bank, invoicing, and expenses in one place, helping you stay on top of your finances from day one.

Other essential tools

Think about tools for project management to keep tasks organised, communication apps to stay in touch with partners or staff, and email marketing services to build a customer list. Starting with the right tools saves you time and helps you focus on growing your business.

Set up your online presence

Your digital presence is how customers discover and interact with your business.

Setting up your online presence means creating the digital infrastructure where customers find you, learn about your offerings, and make purchases. Geography becomes irrelevant online. You can sell to customers anywhere in the country or the world, which is why 63% of accountants and bookkeepers say digital businesses are more likely to be based on novel ideas.

Set up payment processing

You need a way for customers to pay you online. Most ecommerce platforms include payment processing, but you can also use standalone services. Look for options that accept credit cards, debit cards, and digital wallets. Check the transaction fees and how long it takes for money to reach your bank account. Make sure the checkout process is simple and secure so customers feel confident buying from you.

Create your remote workspace

Professional service businesses often already know how to work remotely. There's plenty of great software for creating, sharing, and collaborating on projects. The higher net profit margins of online businesses prove these remote tools are perfectly productive.

Even complex tasks like brainstorming work well online. Michael Yared's app development agency, Echobind, has used remote collaboration tools for years. "Digital brainstorming boards capture ideas from everyone, not just the loudest people in the room," he says. "Plus remote working encourages better documentation because so much is exchanged in writing."

Olivia Park Coaching delivers online physical and wellbeing training to clients across Asia. Olivia Park attracts customers by sharing free content on social platforms, then signs paying customers to self-serve courses. She also offers one-to-one calls and says the digital approach allows her to help twice as many clients. "It's enabled me to create more products with different tiers of service."

If you're building an app, you'll need to turn your idea into working software. The process involves design, development, testing, and launch, with costs varying widely based on complexity.

Market your online business

Getting customers to your online business requires active promotion.

Digital marketing is how you attract visitors to your online business. Unlike physical shops, you can't rely on foot traffic. Every visitor must be earned, and only about 2% will purchase anything.

Pay-per-click advertising can spiral out of control quickly. Online business expert Shaheman Farid has seen failed campaigns burn through thousands of dollars without a single sale.

More than a third of accountants and bookkeepers in the study say digital marketing is a major challenge for new online businesses.

Digital marketing channels to try

There's no single digital marketing playbook that works for every business. You'll need to experiment across different channels to find what works for you:

• Search marketing: Getting found through Google
• Content marketing: Creating articles on LinkedIn or your own blog
• Video marketing: Posting on YouTube or TikTok
• Social media: Building an audience on Instagram, Facebook, or other platforms

Results can be unpredictable, so try several options at the beginning. "You have to experiment, but you can do that without spending a fortune," says Ben Charlton of Air8 Digital. See our guide to digital marketing for low-cost tips.

Set your marketing budget

Budget 40% of your startup costs for marketing. Marc McKeown of FortBrave recommends spending this in the first three months to test what works.

This may sound like a lot, but digital marketing is often your only source of sales or leads. The investment is offset by money you save on fitting out a physical shop or office.

Measure and refine your approach

Track what's working and what's not. Use simple analytics tools to see where your visitors come from, which pages they view, and where they drop off. Test different approaches and double down on what brings results. Digital marketing is an ongoing experiment, so stay flexible and keep learning from your data.

Avoid common mistakes

Starting an online business is an exciting journey, but some common pitfalls can slow you down. Being aware of them from the start can help you save time, money, and stress.

• Underestimating digital marketing: Don't assume customers will just find you. Plan and budget for marketing from day one.
• Skipping market validation: Make sure people actually want what you're selling before you invest too much
• Poor website experience: A slow or confusing website will turn customers away. Make it easy for them to find what they need and make a purchase.
• Ignoring financial management: Keep track of your money from the start. Use software to avoid headaches at tax time.
• Trying to do everything yourself: Focus on what you do best and look for help with other tasks. You can't be an expert in everything.

Get help from an advisor

An accountant or bookkeeper from a professional body with over 140,000 members globally can help you set up your business structure, manage compliance, and get your finances right from day one. They work with online businesses regularly and understand the specific challenges you'll face.
