Key takeaways

• Define your target market before developing your product or service, as this shapes everything from product features to marketing strategy and helps you speak directly to customer problems and goals.
• Validate your business idea by researching competitors, surveying potential customers, and testing with a minimum viable product to confirm real demand before investing significant time and money.
• Budget 40% of your startup funds for digital marketing in the first three months, as online businesses rely entirely on earned traffic and need to experiment across multiple channels to find what works.
• Start with a flexible one-page business plan that you update monthly rather than lengthy forecasts, since digital marketing results are unpredictable and you'll need to adapt quickly based on early experiments.

What goes into starting an online business?

Starting an online business means launching a company that operates primarily through the internet, whether you're selling products, offering services, or creating digital content. The process shares core steps with traditional businesses: developing an idea, writing a plan, and setting a budget. But each element works differently in the digital space.

A survey of 171 experts who work with online businesses reveals what makes them succeed. Here's what they shared:

• Ideas can be more niche: Online reach lets you target specific audiences that wouldn't sustain a physical store.
• Plans can be shorter: You'll learn and adapt faster, so lengthy forecasts aren't always necessary.
• Budgets can be smaller: Lower overhead means you can start with less capital.

You'll find their insights combined with quotes from online business owners and ecommerce consultants throughout this guide.

Online business ideas

Online business ideas are concepts for companies that operate primarily through the internet. Most fall into four main categories:

• Retail and ecommerce: Selling physical products, whether sourced from suppliers or made yourself.
• Service providers: Offering professional services like consulting, design, or coaching remotely.
• Apps and software: Building digital tools or platforms that solve specific problems.
• Content and media: Creating videos, courses, newsletters, or other content that generates revenue.

For more detailed options, see the guide to online business ideas.

Making your idea the best it can be

Online businesses cost less to launch, but they still require significant time and effort. Research helps you refine your idea before you invest that energy.

A little upfront work can reveal whether your concept needs adjustments, or whether a different direction might serve your target market better.

Experts' number one tip for better ideas

Business experts shared their top tips for online startups. The most common answer: define your target market before you do anything else.

Your target market is the specific group of people or businesses who will buy from you, whether that's local parents, fitness enthusiasts, restaurants, or something else entirely.

Once you know who they are, build everything around them:

• Shape your product: Design features and packaging specifically for their needs.
• Focus your marketing: Speak directly to their problems and goals.
• Talk to potential customers: Ask what they think of your idea, pricing, and competitors.
• Research the competition: Find out who they buy from now and why.

Choosing your online business model

Once you have an idea, the next step is to choose a business model. This defines how you'll create value and make money. Your model shapes everything from your daily tasks to your long-term strategy.

Product-based businesses

This model involves selling physical goods. You might make your own products, or source them from a supplier in a model known as dropshipping. It's a great fit if you enjoy creating tangible items or managing inventory and logistics.

Service-based businesses

If you have a specific skill, you can offer it as a service. This could be anything from consulting and design to coaching or freelance writing. Service businesses often have low startup costs and allow you to work directly with clients.

Digital products and content

This model involves creating and selling digital goods like ebooks, online courses, or software. Once created, a digital product can be sold many times without extra production costs, making it a scalable option.

Matching your model to your strengths

Think about what you enjoy doing and what you're good at. A product-based business requires different skills than a service-based one. Choosing a model that aligns with your strengths and interests will help you stay motivated and build a business you love.

Validate your business idea

Before you invest too much time and money, it's important to validate your business idea. This means finding out if there are real customers who are willing to pay for your product or service. A little research now can save you from costly mistakes later.

Steps to validate your idea

Follow these steps to test your concept and see if it has potential.

1. Research your competition. Look at what similar businesses are doing and identify their strengths and weaknesses. For example, a market leader like Amazon maintains a dominant conversion rate of 10–13%. Use this research to find your own opportunity to stand out.
2. Survey potential customers. Ask people in your target market if they would use your product or service. Get their feedback on your idea, features, and pricing.
3. Test with a minimum viable product. Create a basic version of your product or service to see if people will actually buy it. This could be a simple landing page or a small batch of products.
4. Analyse the results. Use the feedback and data you've collected to decide if your idea is worth pursuing. Be prepared to make changes based on what you learn.

Pros and cons of online business

A Xero survey of small business advisors reveals how ecommerce stacks up against traditional brick-and-mortar businesses.

Key findings

The accountants and bookkeepers who completed this survey prepare financial statements for 6,000 small businesses across the US, the UK, and Australia. They compared the performance of online businesses versus brick-and-mortar operations.

Financial performance:

• Profitability: 57% say online businesses have higher net profit margins
• Running costs: Seven in 10 say running a small business online costs less
• Break-even speed: Seven in 10 say online retailers break even sooner than physical stores

Risk and resilience:

• Failure rates: 67% say online businesses are less likely to fail
• Financial exposure: 69% say owners lose less money if an online business does fail

Lifestyle and flexibility:

• Side business potential: Online business owners are twice as likely to hold down a day job
• Stress levels: Just 9% say online owners are more stressed, compared to 48% for brick-and-mortar owners

Startup requirements:

• Retail costs: Six in 10 say retail is cheaper to start online
• Service costs: Two-thirds say services are cheaper to start online
• Innovation: 63% say online businesses are more likely to be based on a novel idea

Common pitfalls

Online businesses come with their own challenges. Here are the most common pitfalls experts identified:

• 35% say digital marketing is difficult: Finding the right channels and tactics takes time and experimentation.
• 33% say transaction fees catch owners off guard: Costs to process payments of up to 5% can eat into margins, as major card networks typically charge 1.5–2.5% or more for each transaction.
• 32% say technology creates confusion: Choosing and managing platforms requires a learning curve.
• 29% say social media and reviews demand too much time: Maintaining an online presence is ongoing work.
• 26% say creating a good website is harder than expected: Templates help, but great user experience often needs professional input.

The online and bricks-and-mortar businesses in this study had comparable revenue so these differences were not likely due to scale. 171 accountants and bookkeepers participated in the study, with an average of 35 clients each (equating to a collective clientele of 6,000 businesses).

Writing an ecommerce business plan

An ecommerce business plan is a document that outlines your online business strategy, goals, and financial projections. Unlike traditional business plans, ecommerce plans are often shorter and more flexible, partly because you may not have enough data to forecast accurately before launch.

Why you don't need a 20-page plan

Traditional 20-page business plans exist mainly to pitch investors and lenders. Since online startups cost less to launch and rarely attract institutional funding, you probably don't need one.

This frees you to create a plan that actually helps you, whether that's 20 pages or just one.

Why you may only need a one-page plan

Almost 60% of new online business owners struggle to forecast revenue for their first few months. That's because digital marketing success is unpredictable. You'll likely test multiple tactics across several platforms before finding what works.

Only after those early experiments will you have enough data to forecast sales accurately.

This uncertainty is why online startups favour shorter, more flexible plans. A one-page plan that you update monthly is often more useful than a detailed forecast that becomes outdated within weeks.

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.

Business registration and legal setup

Setting up your business correctly from the start helps you stay compliant and avoid legal issues. This involves choosing a business structure, registering your name, and getting the right licences.

Choose your business structure

Your business structure affects everything from your taxes to your personal liability. Common options include sole proprietorship, partnership, and a limited liability company (LLC). Each has different legal and financial implications, so it's wise to understand them before deciding.

Register your business

Once you've chosen a structure, you'll need to register your business name. This process varies depending on your location and business type, but in most cases, the total cost to register will be less than $300.

Get necessary licences and permits

Depending on your industry and location, you may need specific licences or permits to operate legally. Research what's required for your online business to ensure you're fully compliant.

Set up business banking and accounting

Keeping your business and personal finances separate is crucial. Open a business bank account and set up accounting software to track your income and expenses from day one. This makes managing your money and filing taxes much easier.

Creating a budget for a digital business

A digital business budget is a financial plan that maps out your expected costs and when you might start generating revenue. Even though online businesses cost less to run than physical ones, beginners often overlook significant expenses.

Creating a budget helps you understand what you'll spend, when bills will hit, and how long until the business pays for itself.

3 common ecommerce budgeting mistakes

Beginners often overlook three key expenses:

• 37% underestimate digital marketing costs: Most ads charge per click, and only about 2% of visitors convert to buyers, so costs add up quickly.
• 35% underestimate website costs: Templates are affordable, but creating a great user experience often requires professional help.
• 33% underestimate transaction fees: Payment processors take up to 5% of each sale, which needs to be factored into your pricing.

How to do a budget

Here's how to create your budget:

1. List all business costs: Include one-time startup expenses and recurring monthly costs
2. Plot costs on a calendar: Know when each expense will hit your account
3. Add modest sales projections: Estimate conservatively for your first few months
4. Plan for the gap: You'll likely be in the red early on, so ensure you can cover bills in the meantime

Online business consultant Shahemen Farid of Boobooks Accountants recommends starting with three months of working capital. "We suggest clients base their forecasts on that first quarter," he says.

Budgeting for an online business? See the SBA's guide to calculating startup costs for a breakdown of typical expenses.

Experts' pricing tip for online businesses

While online businesses are cheaper to run, they're not expected to pass those savings onto customers. 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 to be free: a critical consideration, given that high extra costs drive 48% of abandonment. But some will go into the business owner's pocket, with the study confirming that ecommerce businesses have higher net profit margins.

Finance options for an online business

Financing an online business is often easier than funding a physical store because startup costs are lower. Banks rarely finance online startups without an established track record, but many founders self-fund successfully.

Service businesses typically have minimal startup costs:

• You may only need a laptop and software subscriptions
• You can grow from freelancing, keeping overhead low from the start

Retail businesses require more capital but offer flexibility:

• Start with limited inventory and scale up once demand is proven
• Launch softly to reduce risk compared to stocking a physical store

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

Sources of extra cash

If you need additional funding, consider these options:

• Credit cards: Provide quick access to capital, but interest rates are typically high
• Personal loans: May require collateral such as property or savings from banks
• Friends and family: May lend money or invest in exchange for equity
• Angel investors: Industry contacts occasionally back promising startups
• Crowdfunding: Works best for ideas with broad appeal and viral potential
• Grants: Available for cause-driven or innovation-focused businesses

Choose your ecommerce platform and tools

The right technology will make running your online business much smoother. From your website to your payment system, these tools form the backbone of your operations.

Ecommerce platform options

Your ecommerce platform is where you'll build your online store. Options range from all-in-one solutions that are easy for beginners to more customisable platforms that offer greater flexibility. Choose one that fits your technical skills and business needs.

Essential business tools

Beyond your website, you'll need tools for email marketing, customer communication, and project management. Start with the essentials and add more as your business grows and your needs evolve.

Payment processing solutions

To accept payments online, you'll need a service that processes payments. Look for a provider that is secure, easy to integrate with your platform, and has clear, competitive transaction fees.

Accounting and financial management

Good financial software is non-negotiable. It helps you track sales, manage expenses, and understand your profitability. Choosing a tool that automates tasks like reconciling your bank accounts will save you valuable time.

How to set up an online shop, office, or app

Setting up your online presence means creating the digital infrastructure where customers find you, interact with your business, and make purchases. Geography becomes irrelevant; you can serve customers anywhere in the world.

This global reach explains why 63% of experts say online businesses are more likely to be based on niche or novel ideas. Here's how to build your digital presence based on your business type.

Creating an online shop

Retailers have two main options for selling online:

Existing marketplaces (Amazon, Alibaba, Facebook):

• Pros: Fast setup, built-in ability to process payments, access to existing customer base
• Cons: Limited control over branding, marketplace takes a cut of each sale

Your own online shop (Shopify, Square, BigCommerce):

• Pros: Full control over design and customer experience, stronger brand presence
• Cons: Monthly subscription fees, transaction fees, steeper learning curve

If you build your own shop, take time to get the user experience right. More flexibility means more potential for mistakes.

Setting up an online office

Setting up an online office requires software that helps you collaborate, create, share, and manage projects remotely. The tools available today are highly effective: online businesses have higher net profit margins than physical equivalents, proving remote work doesn't hurt productivity.

Even complex tasks like brainstorming work well online. Michael Yared, whose app development agency Echobind has worked remotely for years, says digital tools can be better than in-person sessions:

• More inclusive input: "Digital brainstorming boards capture ideas from everyone, not just the loudest or highest-paid people in the room"
• Better documentation: "Remote working encourages better documentation because so much information is exchanged in writing"

Creating an online studio

Creating an online studio works well for coaches, trainers, and creators who deliver expertise through digital content. This model typically combines free content to attract audiences with paid offerings for revenue.

Olivia Park Coaching uses this approach to deliver physical and wellbeing training across Asia:

• Free content on social platforms: Attracts potential customers
• Self-serve courses: Provide scalable revenue
• One-to-one calls: Offer premium, personalised service

"The digital approach allows me to help twice as many clients," Park says. "It's enabled me to create more products with different tiers of service."

Building an app

Building an app requires turning your idea into working software: a process with specific costs and common pitfalls to avoid.

An app development company shared insights on how apps are made and what they typically cost. For detailed guidance, see the SBA's guide to registering your business.

Digital marketing 101

Digital marketing is how online businesses attract visitors and convert them into customers. Unlike physical stores, you won't get foot traffic. Every website visit must be earned.

The challenge is significant:

• Only about 2% of visitors convert: Most people who visit your site won't buy anything
• Pay-per-click costs add up fast: Expert Shahemen Farid has seen campaigns spend thousands without a single sale
• 35% of experts call it a major challenge: Digital marketing is one of the hardest parts of starting an online business

The unsatisfying secret to digital marketing

There's no single digital marketing strategy that works for every online business. Results are unpredictable, and most tactics won't deliver the returns you expect.

The solution is experimentation. Test multiple approaches early:

• Try search marketing through Google
• Create content on LinkedIn or industry blogs
• Post video on YouTube or TikTok
• Share social storytelling on Instagram

"There's no telling what will work and what won't," says Ben Charlton of Air8 Digital. "You have to experiment. But you can do that without spending a fortune."

For low-cost tactics, see the SBA's guide to marketing and sales.

How much to budget for digital marketing

Ecommerce consultant Marc McKeown of FortBrave recommends keeping 40% of your startup budget for marketing. "We'd spend that in the first three months to see what things work and make a plan from there," he says.

That percentage may seem high, but digital marketing is often your only source of customers. The investment is offset by savings on physical space: money you'd otherwise spend fitting out a shop or office.

FAQs on starting an online business

Here are answers to common questions about launching an online business.

What is the easiest online business to start?

Service-based businesses like freelance writing, virtual assistance, or consulting are typically easiest because they require minimal upfront investment, often just a laptop and internet connection.

How long does it take to start an online business?

You can launch a simple online business in a few weeks. However, building consistent revenue typically takes three to six months as you experiment with marketing and acquire customers.

Can I start an online business with no money?

Yes, service businesses can start with minimal investment if you already have a computer and internet access. Product businesses require inventory costs, but starting small with limited stock reduces upfront spending.

What's the difference between an online business and an ecommerce store?

With an ecommerce store, you specifically sell physical or digital products online. An online business is broader. It includes ecommerce but also covers service providers, app developers, content creators, and other business models that operate primarily through the internet.
