Selling online takes away the rent, the shopfront and the commute, and replaces them with one cost you cannot avoid: getting found. That is true of every idea below. Setting up a shop or a service page now takes an afternoon and very little money — the work, and usually the money, goes into being the thing someone finds when they go looking. Here are the routes that genuinely work for UK beginners, and what each really takes.
At a glance
| Feature | Detail |
|---|---|
| Fastest to first money | Selling a service remotely — you can be paid in your first month |
| Lowest startup cost | Services and digital products: a laptop, a way to take payment, and time |
| Needs real money up front | Stocked ecommerce — you buy the stock before anyone buys it from you |
| The real cost of "online" | Traffic. Being found is the job, and it is either paid for with money or with months |
| Marketplace or own site | Marketplaces bring buyers and take a cut; your own site keeps the margin and brings nobody |
| Legal bits to sort | Consumer cancellation rights on distance sales, and ICO registration (£52 a year) if you hold personal data |
First, the thing nobody puts in the list
An online business has three parts: something to sell, somewhere to sell it, and a reason anyone turns up. The first two are easy now. The third one is the business.
A new website has no visitors. None. Left alone it stays that way, because search engines rank pages that have earned it and social platforms show things that already get attention. So every online business has to pick how it pays for traffic, and there are only really three options: money (ads, which work immediately and stop working the day you stop paying), time (content and search rankings, which take months and then keep giving), or someone else's audience (a marketplace like Etsy, Amazon or Vinted, which brings you buyers and takes a cut for it).
None of those is wrong. What is wrong is planning as though customers simply arrive. If you take one thing from this page, budget for traffic the way a shop budgets for rent.
Selling a service remotely
The fastest route to actual money, and the one most people should start with. Copywriting, design, bookkeeping, social media management, virtual assistance, translation, online tutoring, CV writing, consulting in whatever you already do for a living.
Why it beats the others at the start: you can charge a real price immediately, you need no stock, and one client can be found by asking rather than by advertising. Ten clients paying £300 a month is a living; ten sales of a £20 product is nothing.
The limit is that you are selling hours, so income has a ceiling. Most people who start here eventually raise prices, specialise, or add something that sells while they sleep — which is the next section.
Digital products
Templates, planners, guides, courses, presets, spreadsheets, printables. Made once, sold many times, with almost no cost per sale.
The appeal is obvious and the catch is the same as always: nobody knows the product exists. Digital products work best as a second act, sold to an audience you already built doing something else — the tutor who sells revision packs, the bookkeeper who sells a simple set of templates. Starting cold with a digital product and no audience is the hardest version of this business, not the easiest.
Price them properly. A £7 product needs an enormous number of sales to matter; a £70 product that solves a real problem for a specific person often sells more easily than the cheap one.
Ecommerce and print-on-demand
Print-on-demand puts your designs on t-shirts, mugs and prints that only get made when someone buys. No stock, no risk, and thin margins — the printer takes most of the money, so this lives or dies on whether you can get people to the page cheaply.
Stocked ecommerce is the real version: you buy the stock, you hold it, you ship it. Better margins, and genuine money at risk before a single sale. Add the costs people forget — packaging, postage, returns, card fees, breakages and the ones that never sell — because they are the difference between a healthy margin and a busy hobby.
Dropshipping sits in between and is harder than it looks. You are selling something anyone else can also sell, from the same supplier, so the only lever you have is advertising, and you are competing with people who are better at buying ads than you.
Marketplaces or your own site
Not a moral question, just arithmetic.
A marketplace — Etsy, eBay, Amazon, Vinted, Not On The High Street — brings you buyers on day one. Someone is already searching there with a card in their hand. You pay for that in listing fees and commission, you compete on the same page as everyone else, and the customer is the marketplace's, not yours.
Your own site keeps the margin and the customer, and starts with no visitors at all. It only pays once you have some way of bringing people to it.
For most beginners the sensible answer is to start on a marketplace, prove people want the thing, and build your own site once you know they do — running both, with the marketplace as your shop window.
Content and affiliate
Building an audience — a blog, a YouTube channel, a newsletter, a niche site — and earning from ads, affiliate commission or sponsorship.
It is a real business and it is the slowest one on this page. Expect a year or more before it pays anything meaningful, and expect the platform rules to change under you. Where it works well is alongside something else you sell: the audience makes the products easy, rather than the other way round.
Getting found, without wasting money
Two rules save beginners most of the money they lose here.
Pick one channel and do it properly. One platform posted on consistently beats three done occasionally, and the right one depends on what you sell — Instagram if the work sells in pictures, Facebook if it sells locally or by recommendation, search if people are actively looking for the thing you make.
Know what a customer is worth before you pay for one. If your profit on a sale is £12, you cannot spend £20 winning it, and quite a lot of new online businesses discover that after the money is gone. Our guide to marketing a small business covers the channels properly, and Plan can work out what you can afford to spend from your own numbers before you spend it.
The legal bits for selling online
Short, but not optional.
Selling to consumers at a distance brings specific duties: clear information about you, the product and the total price before they buy, and generally a 14-day right to change their mind and get a refund on goods bought online, whether or not there was anything wrong with them. That right to cancel is the one that surprises new sellers, and it has to be built into your returns policy and your margins. Goods also have to be as described and fit for purpose.
Your details on the site. Businesses selling online have to show who they are and how to contact them, with more required of limited companies.
Personal data. If you handle customers' personal information — and an order list is personal information — you may need to register with the Information Commissioner's Office and pay the annual data protection fee, £52 for most small businesses. You also need a privacy notice telling people what you do with their data.
What the numbers actually look like
Take Rosie, who sells digital wedding planning templates from home at £18 a set. There is nothing to make after the first time and no postage, so almost all of that £18 is hers after the platform's fee.
She wants £1,500 a month from it. That is 83 sales a month, or roughly three a day. Now the bit that decides whether this works: if two visitors in every hundred buy, those 83 sales need around 4,200 visitors a month. Not 4,200 people who like the idea — 4,200 people arriving on the page.
That is the whole business in one number. Everything else — the design, the shop, the pricing — is an afternoon's work compared with finding 4,200 people a month, every month. She can pay for them with ads, in which case her real question is what she can afford per visitor, or earn them with content and search over a year or so.

Frequently asked questions
What is the easiest online business to start in the UK? Selling a service you can already do — copywriting, bookkeeping, design, tutoring, social media management, virtual assistance. You can charge a real price straight away, you need no stock, and your first clients usually come from people you already know rather than from advertising.
How much does it cost to start an online business? A service business can start for the price of a domain and a simple site. Stocked ecommerce needs real money because you buy the stock before anyone buys it from you. In every case, budget for getting found — that is the recurring cost that replaces rent.
Do I need to register a business to sell online? Yes, once you are trading rather than selling a few personal belongings. Most people start as sole traders and register with HMRC; some form a limited company. Our guide to starting a business covers which suits which situation.
Do I have to accept returns on things sold online? Generally yes. Consumers buying at a distance usually have 14 days to change their mind and get a refund, even if nothing is wrong with the item, with some exceptions such as personalised goods and digital downloads. Build returns into your margins from the start.
Do I need to register with the ICO for an online business? Possibly. If you handle personal data — customer orders, an email list — you may need to register with the Information Commissioner's Office and pay the annual data protection fee, £52 for most small businesses. You also need a privacy notice explaining what you do with people's data.

What is Plan?
Plan is a free business operating system for people starting or newly running a UK business. It walks you, one simple step at a time, from your elevator pitch through brand, product and pricing, to a complete business plan — then uses everything it now knows about the business to help with the basics: logo and brand, marketing, a website, a bank account, funding, insurance, company registration. You can use as much or as little as you want.
Two ways to do this
Work the idea out, free. Plan turns any of these into real numbers — your price, your margin, how many sales it takes and what you can afford to spend winning them — one short question at a time in your browser. There are more options in our full list of business ideas, and the ones that work from a kitchen table are in our home business ideas guide.
