E-commerce is one of the most straightforward businesses to begin in the UK. Regardless of whether you want to start a side business, earn a full-time income, or build a sustainable online business, e-commerce is a great option thanks to its flexibility, low initial investment, and large market.
That said, e-commerce is the simplest type of business to set up, but starting one successfully requires planning. That is because even though setting up the store is simple, there is a lot of planning and groundwork that goes into starting a successful business. This may include setting up the correct accounting, understanding initial costs, managing VAT, and more.
This guide aims to inform you how to start an e-commerce business in the UK, including expenses, time, and overall framework.
What is an e-commerce business?
E-commerce businesses sell products or services online, without a physical storefront. In the UK, ecommerce businesses sell products online using:
- Online marketplaces
- Their own ecommerce website
- A mix of the two
Many beginners choose online marketplaces for their wide customer reach. eBay, for example, allows new sellers to list items quickly with little setup required. However, signing up as a seller on eBay is only the beginning as there are several steps needed to create attractive listings that capture buyers’ attention.
Marketplaces like Etsy are ideal for selling niche or handmade products. While selling on these platforms makes it easier to reach customers, sellers must also navigate platform fees, payout delays, and VAT requirements.
Choosing the right platform and business model
A critical early decision is how and where to sell your products. This will impact your costs, bookkeeping, branding, and control over your business. Some entrepreneurs prefer launching their own online store using platforms like Shopify, which streamlines inventory, payments, and business management. Others start with marketplaces to tap into existing customer bases. Many successful sellers eventually use both approaches to maximize sales opportunities.
Your business model is equally important. There are several types of small e-commerce business models in the UK, including dropshipping, warehousing, and hybrid models. Each comes with its own set of benefits and challenges. Explore the types of small e-commerce business models in the UK to find the approach that suits you best.
Is starting an e-commerce business worth It?
Starting an e-commerce business can be financially rewarding, but it doesn’t guarantee profitability. E-commerce, as a business, depends heavily on potential returns, costs, and your business planning. It makes a difference in whether you generate a profit or a complete loss.
For instance, an Amazon seller can achieve significant sales in a short span. However, after you deduct Amazon fees, fulfilment costs, advertising spend, and VAT from the sales, your profit can go below zero, barely cover the price, or even result in a loss.
Successful e-commerce businesses tend to:
- Have a good understanding of profit margins
- Have a good understanding of delivery and platform fees
- Have a good understanding of taxes and VAT
Is starting an e-commerce business hard?
Starting an e-commerce business from a technical perspective is easy. Most platforms let you list your products and set up payments in a matter of days.
The genuine hurdle is what happens after you launch. As your e-commerce business grows, you need to manage:
- Refunds and returns
- Levels of stock and inventory
- Delays in payments and fees from platforms
- VAT registration and thresholds
- Year-end tax obligations
Using fulfilment services like Amazon FBA increases these challenges.
How much does it cost to start an e-commerce business?
This is a common question that depends on your business model. However, there are always costs associated with running e-commerce businesses, both recurring and one-time.
When it comes to starting an e-commerce business, here are some common startup costs to consider:
- Marketplace and selling channel transaction and subscription fees
- Website domain registration, hosting, and custom URL fees
- Website and brand design costs, including logo
- Website payment processor fees
- Stock, supplier, and inventory costs
- Marketing, advertising, and promotional costs
- Accounting and legal professional fees
Depending on the business model, e-commerce businesses may need anywhere from under £500 to several thousand pounds to get up and running. Businesses also need to budget for costs beyond launch, as e-commerce startups spend many months before reaching profitability.
Need help with your Ecommerce business?
Let’s have a discussion about how we can help you grow with confidence.
Can you start an e-commerce business with no money?
It can be considered (almost) free when starting an e-commerce business utilising the dropshipping model. Dropshipping is when the e-commerce business owner does not store inventory and is only responsible for redirecting customer orders to suppliers.
This is often the preferred model for beginners, and Shopify is the preferred selling channel as it offers cheap starting model.
Starting e-commerce journeys is one of the easiest ways to start a business as it has the least risk attached; however, it does come with its own complexities, such as:
- Loss of profit margins
- Complex VAT considerations
- Increased Advertising costs
How to start an e-commerce business from Home
Building an e-commerce business allows you to work from home, especially during the first phase of business, when keeping costs to a minimum is one of the biggest priorities, whilst focusing on product and market fit.
Building an e-commerce business from home means:
- Managing your own online store
- Keeping some inventory
- Outsourcing fulfilment as sales grow
Some entrepreneurs combine home fulfilment with outsourced fulfilment, such as Amazon FBA. This method can be efficient, but it introduces additional VAT and accounting considerations.
How long does it take to start an e-commerce business?
Setting up an e-commerce business can take anywhere fromtwo to six weeks, depending on the platform you choose and your level of preparation. However, it is also important to note that it can take a very long time to build that e-commerce business into a profitable venture.
Founders commonly focus on:
- Researching products and suppliers.
- Configuring their selected platform.
- Testing various pricing and marketing strategies.
Launch timelines are compressed thanks to social commerce platforms. For example, TikTok Shop is a valid initial sale. While a short launch timeline is possible, a well-thought-out financial plan is crucial.
E-commerce accounting, VAT and tax considerations
Most founders underestimate the complexities of accounting, VAT, and taxes when kickstarting their e-commerce ventures. The nature of e-commerce is such that it generates high transaction volume across various platforms, compounded by differing VAT jurisdictions and regulations especially if you sell to overseas customers.
Other than the basics that are obvious in any industry, it is important that you are:
- Tracking your income and expenses,
- Accounting for and filing your VAT (if you are registered),
- Accounting for platform fees and refunds,
- Determining your corporation vs. income tax obligations,
There are also complications arising from selling on marketplaces, importing stock, and using fulfilment services, all of which add to the VAT burden. The absence of systems will result in mismanaged compliance and hefty penalties from the tax authorities.
Common mistakes e-commerce businesses end up making
E-commerce businesses make mistakes that could easily be avoided and have far more damaging impacts than a simple lack of demand. Examples of these mistakes are:
- Not registering for VAT on time.
- Having a mix of personal and business finances.
- Not setting money aside for taxes.
- Not differentiating between turnover and profit.
Identifying and correcting these mistakes early can help businesses achieve far greater growth potential.
