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 3 months, as online businesses rely entirely on earned traffic and need to experiment across multiple channels to find what works.
- Register your business with the Accounting and Corporate Regulatory Authority (ACRA) early and set up accounting software from day one to stay compliant and keep your finances organised as you grow.
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 4 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. If you plan to work from your residence, explore home business ideas for Singapore.
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
Your business model defines how you'll create value and make money. Once you have an idea, choosing the right model is the next step. It 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
Validating your business idea means finding out whether real customers are willing to pay for your product or service before you invest too much time and money. 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.
- 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.
- 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.
- 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.
- 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. The findings show clear advantages for online businesses across profitability, costs, and lifestyle factors.
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: 7 in 10 say running a small business online costs less
- Break-even speed: 7 in 10 say online retailers break even sooner than physical stores
Online businesses also show greater resilience: 67% of advisors say online businesses are less likely to fail, and 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: 6 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
Registering your business correctly from the start helps you stay compliant and avoid legal issues in Singapore. This involves choosing a business structure, registering with the Accounting and Corporate Regulatory Authority (ACRA), and getting the right licences.
Choose your business structure
Your business structure affects your taxes, personal liability, and compliance obligations. In Singapore, the most common structures for online businesses are:
- Sole proprietorship: Simplest to set up with the lowest registration fees, but you're personally liable for all business debts
- Partnership: Similar to a sole proprietorship but with 2 or more owners sharing responsibility
- Private limited company (Pte Ltd): A separate legal entity that protects your personal assets from business liabilities, and is the most common structure for businesses planning to scale
A Pte Ltd structure also makes it easier to attract investors and access government grants. It's wise to speak with an accountant to understand which structure suits your situation.
Register your business with ACRA
Once you've chosen a structure, register your business through ACRA's BizFile+ portal. Sole proprietorships and partnerships cost S$115 per year to register, while incorporating a Pte Ltd company costs S$315 as a one-time fee.
You can complete the registration online through GoBusiness, the Singapore Government's one-stop portal for business registration and licensing. The process typically takes 1–2 business days for sole proprietorships and up to 2 weeks for Pte Ltd companies.
Get necessary licences and permits
Depending on your industry, you may need specific licences to operate legally in Singapore. For example, food-related online businesses need a licence from the Singapore Food Agency. Use the GoBusiness Licences and Permits Recommender to check what's required for your business type.
Set up business banking and accounting
Keeping your business and personal finances separate is crucial, especially if you're operating a Pte Ltd company. 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.
If your annual taxable turnover exceeds S$1 million, you'll also need to register for Goods and Services Tax (GST). Even if you're below this threshold, tracking your revenue accurately from the start will help you stay prepared.
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 3 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:
- List all business costs: Include one-time startup expenses and recurring monthly costs
- Plot costs on a calendar: Know when each expense will hit your account
- Add modest sales projections: Estimate conservatively for your first few months
- 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 3 months of working capital. "We suggest clients base their forecasts on that first quarter," he says.
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, and you can grow from freelancing to keep overhead low from the start.
Retail businesses require more capital but offer flexibility. Start with limited inventory and scale up once demand is proven, or 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
Singapore government grants and support
Singapore offers several government-backed funding schemes designed to support new businesses. These can significantly reduce your upfront costs:
- Startup SG Founder: Provides mentorship and a startup capital grant of up to S$50,000 for first-time entrepreneurs with innovative business concepts
- Enterprise Development Grant (EDG): Supports up to 50% of qualifying project costs for businesses looking to upgrade capabilities, innovate, or expand overseas
- Productivity Solutions Grant (PSG): Covers up to 50% of the cost of pre-approved digital solutions, including accounting software, to help businesses go digital
You can explore available grants and eligibility criteria on the GoBusiness portal.
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 2 main options for selling online:
Existing marketplaces like Amazon, Lazada, and Shopee offer fast setup, built-in payment processing, and access to an existing customer base. The trade-off is limited control over branding and a percentage of each sale going to the marketplace.
Building your own online shop with platforms like Shopify, Square, or BigCommerce gives you full control over design, customer experience, and brand presence. The trade-off is monthly subscription fees, transaction fees, and a 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:
"Digital brainstorming boards capture ideas from everyone, not just the loudest or highest-paid people in the room," Yared says. He also notes that 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.
Before committing to app development, consider starting with a web-based minimum viable product to validate demand. This approach lets you test your concept with lower upfront investment.
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."
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. For a structured approach, download Xero's free marketing plan template.
Converting visitors into customers
Getting visitors to your website is only half the challenge. Converting those visitors into paying customers requires a smooth, trustworthy experience that makes it easy to buy. Even small improvements to your conversion rate can have a big impact on revenue.
Make your website easy to use
A clear, simple website layout helps visitors find what they're looking for quickly. Focus on fast page load times, easy navigation, and a checkout process with as few steps as possible. On mobile, this matters even more: most online shoppers in Singapore browse on their phones.
Use clear calls to action
Every page on your site should guide visitors toward a specific action, whether that's adding a product to their cart, signing up for a free trial, or requesting a quote. Use clear, descriptive button text that tells visitors exactly what will happen when they click.
Build trust with customer reviews
Social proof is one of the most effective ways to convert hesitant visitors. Display customer reviews, testimonials, and ratings prominently on your product or service pages. Encourage satisfied customers to leave reviews by following up after a purchase.
Test and improve continuously
A/B testing lets you compare 2 versions of a page, headline, or call to action to see which performs better. Start with high-impact elements like your homepage headline, product images, or checkout flow. Track your results over time and make changes based on data rather than assumptions.
Compliance and data protection
Running an online business in Singapore means meeting specific legal and data protection requirements. Understanding these obligations from the start helps you avoid penalties and build trust with your customers.
Personal Data Protection Act (PDPA)
The Personal Data Protection Act (PDPA) governs how businesses in Singapore collect, use, and disclose personal data. If your online business collects customer information such as names, email addresses, or payment details, you need to comply with the PDPA.
Key requirements include:
- Obtaining consent before collecting personal data
- Informing customers about why you're collecting their data and how it will be used
- Protecting personal data with reasonable security measures
- Appointing a data protection officer, even if you're a small business
E-commerce consumer protection
Singapore's Lemon Law (Consumer Protection (Fair Trading) Act) gives online shoppers the right to a repair, replacement, refund, or price reduction if goods don't match their description or are faulty. Make sure your product listings are accurate and your return policy is clearly stated on your website.
If you sell to customers overseas, you may also need to comply with data protection laws in those countries, such as the General Data Protection Regulation (GDPR) for European Union customers.
Keeping your business records in order
ACRA and the Inland Revenue Authority of Singapore (IRAS) require businesses to maintain proper records and file annual returns. Sole proprietors and partnerships must renew their registration annually. Pte Ltd companies must file annual returns with ACRA and submit tax returns to IRAS.
Using accounting software from the start makes compliance simpler. It keeps your financial records organised, generates reports for tax filing, and gives you a clear picture of your business performance at any time.
