Read this first. Nothing on this page promises profitability. It describes the business, its costs, its skills and its risks — including the risk that it does not work. Costs are given as categories with what to price, not as a single figure, because the real figures depend on your own quotes. No income figure on this site is a promise.
Business description
An e-commerce store business sells physical products online through a storefront of its own. The model is chosen first — dropshipping, print on demand, own stock, or a marketplace — and everything after it follows: what you pay up front, who holds the stock, who handles a return, and what happens when the supplier fails. The store is a business with inventory, shipping and customers, not a page with a buy button.
Target customer
Consumers who buy the kind of product you sell, found through search, social media or a marketplace. The best first customers are the audience of one narrow product range — a shop that sells one kind of thing well is easier to run and easier to find than a shop that sells everything thinly, and its customers come back for the thing it does well.
Skills required
Product research by validation, not hype; pricing from full costs; customer service, including returns, in writing; and basic store skills — product pages that tell the truth, clear shipping information, and a checkout that works on a phone. You do not need all of these on day one, but the store that lacks them loses the customers it pays to win.
Startup requirements
A storefront — your own store or a marketplace listing — a product source with real prices and shipping times, and a payment method that can receive money. Own stock needs money in products before the first sale; dropshipping and print on demand need almost no stock money, but need a supplier you have checked. A returns policy, written before the first order, is startup work, not a later fix.
Operating costs
Categories: product and supplier shipping costs; platform and payment fees per sale; advertising per order — the cost beginners underestimate most; and the tax to set aside. Get your own quotes for every one of these before you decide the model: a store priced from guesses is a store that discovers its costs from its losses.
Monetization model
Per product, sold through the storefront or a marketplace, with the margin modelled in the profit calculator: price minus product, shipping, fees and advertising, with refunds counted as a loss. Some stores add subscriptions or bundles later; the first job is a single product that pays after everything it cost to win and fulfil.
Risks
Thin margins: low-price products leave little after product, shipping, fees, advertising and refunds, and a store can sell every day and lose money on every order. Supplier failure: a supplier who ships late, ships wrong, or disappears leaves you holding the customer's complaint. Returns and chargebacks: a damaged or late product comes back as a refund and a review, and payment disputes cost fees as well as the sale. Advertising waste: spending on ads before the product and the price are validated is the fastest way to lose money in e-commerce. Platform dependence: a marketplace can change its fees or close an account, and a store that lives only there goes with it.
Practical first steps
1. Choose a model from your budget and your tolerance for stock — score them with the model comparison tool. 2. Validate one product: searches, price maths with the profit calculator, and how you would reach the buyers. 3. Order one unit yourself and check it before you sell it. 4. Write the returns policy and the shipping information before the first order, and start with a small test, not a full launch.

Frequently asked questions
How much money do I need to start an online store?
It depends on the model: print on demand can start with almost no stock cost, while holding your own stock needs money in products first. Advertising is the cost beginners underestimate most — price it with real quotes before you decide.
Dropshipping or own stock — which should I choose?
It depends on your budget and the control you want. Dropshipping is cheap to start but gives you no control over quality or shipping; own stock is expensive but gives you both. The business models guide compares them on the same terms.
What is the most common beginner mistake in e-commerce?
Counting price minus product cost as profit, and forgetting advertising, fees and refunds. A store can sell every day and lose money on every order — the profit calculator shows the full cost before you spend.
Do I need a returns policy before the first order?
Yes. Returns are part of fulfilment, not an exception — a store with no policy invents one under pressure from its angriest customer, and the fulfilment guide shows how to write a fair one.
