What is e-commerce? How to succeed in e-commerce

What is e-commerce?

E-commerce is the sale of products or services through digital channels, most often an online store, B2B platform, or shopping app. It is more than a catalogue and a “buy now” button. Effective e-commerce connects the offer, payment, delivery, customer service, data, and the team’s day-to-day work.

So instead of asking “do we need a store?”, ask which buying problem it should solve for the customer and how the company will keep its promise after an order is placed. A store with a dozen products is designed differently from an ordering portal for partners or a platform where the offer, availability, or price depends on the customer.

What e-commerce models are there?

Four transaction models are most commonly discussed:

• B2C (business to consumer) — a company sells directly to consumers, for example through a retail store;
• B2B (business to business) — the offer and purchase process are aimed at other companies;
• C2C (consumer to consumer) — users transact with one another through a platform;
• C2B (consumer to business) — an individual offers value to a company, for example work, a licence, or a service.

The distinction helps, but should not end the discussion. In practice, one company may serve retail customers and wholesale partners, while the store can simultaneously be a sales tool, a brand touchpoint, and a source of insight into customer needs. More important than the label is knowing who makes the decision, what information they need, and what happens after payment.

Your own store or a marketplace - which should you choose?

A marketplace makes it easier to reach an existing group of buyers and quickly test part of an offer, but it imposes presentation rules, fees, and limited access to the customer relationship. Your own store gives more control over the brand, data, process, and integrations, but requires you to acquire traffic and maintain the entire experience yourself.

Criterion	Marketplace	Your own store
Launch	usually faster for a standard catalogue	requires process and technology setup
Reach	uses the platform’s audience	the company builds its own channels
Control	limited by rules and format	greater control over the offer and journey
Data and relationship	depends on the platform’s capabilities	can feed your own service and development
Risk	dependence on one platform	responsibility for operations and maintenance

The channels do not have to be mutually exclusive. A sensible arrangement may use a marketplace for selected products and an owned store for the full offer, content, and service of returning customers. The condition is consistency of prices, stock, and responsibility for each order.

E-commerce is a sales system, not just a website

Customers see a category, product page, basket, and confirmation. The team also needs current information about products, stock, prices, payments, delivery, returns, and contact. When these elements are inconsistent, even a striking store loses trust: a delivery promise is outdated, a description does not answer a question, or support cannot see the order history.

Before work begins, describe the entire order journey:

1. How does the customer arrive at the offer, and what are they looking for?
2. How do they recognise that the product or service is right for them?
3. How do they choose a variant, delivery, and payment method?
4. Who fulfils the order, and where do they get the information they need?
5. How does the customer get help when something does not go to plan?

This description quickly reveals whether the issue lies in the purchasing layer, a disordered catalogue, missing integrations, or an unclear post-purchase process.

What makes a store useful?

The first foundation is the offer. Categories should match customers’ language, and filters should narrow the choice without hiding important products. A product page should make the decision easier: clearly show the purpose, variants, price, availability, delivery, and what genuinely distinguishes the product from alternatives. If a purchase requires consultation, do not pretend it is a simple basket — offer a clear next step.

The second foundation is the purchase journey. Customers should not have to return to previous screens to find answers to basic questions or discover costs only at the end. Test it on a phone, on a slower connection, and from the perspective of someone who does not know the company. That is a simpler test than a giant “best practices” list and usually exposes the real obstacles.

The third is trust. A store builds it through consistency: reliable information, predictable communication, accessible help, and confirmation that explains what will happen after purchase. Decorative graphics cannot replace an answer about the product, timing, or returns.

What will a store not solve by itself?

E-commerce will not repair an unclear offer or fulfilment problems. If the company cannot explain what differentiates its product, customers will not be able to judge it from a random description either. If availability is uncertain and the team has no agreed service process, automation will only pass the problem to more people faster.

Before implementation, examine a few uncomfortable questions. Does the price and margin support online sales? Will someone maintain product-data quality? Are delivery terms clear to customers? Does sales have an owner in the company? The answers need not be perfect, but they should identify risks the project needs to resolve rather than conceal.

In more complex sales, a store may be only one element of the process. Some customers will need a quote, consultation, or access to an individual catalogue. Then it is better to design a coherent transition from an information page to a conversation than to force every contact into an anonymous order.

Technology follows the process

Technology should support the sales model, not impose one on the company. A ready-made platform makes sense when the offer and process are relatively standard and the team needs efficient content and product management. A custom solution becomes justified when non-standard configurations, sophisticated B2B roles, integrations, product data, or a specific pricing method are critical.

Before deciding, write down:

• the source of the catalogue, prices, and stock;
• required payment, logistics, accounting, or CRM integrations;
• customer roles and rules for access to the offer;
• people who will update the store after launch;
• elements that cannot be interrupted during migration.

Include the cost of ongoing work too: data updates, handling exceptions, and developing integrations. It often determines whether the solution remains convenient after launch.

That is a better basis for a conversation than a platform feature list. If you are planning a new store or organising an existing one, see how we deliver e-commerce stores.

How do you prepare the first project scope?

At the start, do not try to describe every exception. Choose the most important customer group, the main buying scenario, and the offer whose sale will bring the most learning. For that part, prepare requirements for the catalogue, payment, delivery, communication, and post-purchase service. Also identify decisions that must be made by the business rather than technology.

It helps to agree readiness criteria. A store is not ready because every screen has a design. It is ready when a customer can complete the key purchase, the team can fulfil the order, information is consistent, and important scenarios have been checked. Such criteria reduce the risk of a long project in which basic decisions are still missing.

Content helps people buy before it starts selling

A category description, product page, guide, and answer to a customer question have different roles. Their job is not to repeat the same phrase, but to reduce uncertainty at a particular decision stage. A guide can explain a problem and help compare options, while a product page should state precisely what the customer is buying and on what terms.

Prepare a content plan alongside the catalogue. Collect questions that recur in sales and support, name the differences between products, and explain concepts necessary for a decision. This creates a useful knowledge base for customers and material for developing the offer, rather than articles unrelated to the real purchase journey.

How do you grow sales after launch?

Store launch is the beginning of learning, not the end of the project. Watch where customers stop in the journey, what they ask support about, and which products need better explanation. Numbers are useful when they lead to decisions — we describe that approach in our article on KPIs.

Do not try to improve everything at once. Choose one constraint, such as an unclear category, overly long form, or manual data re-entry; define an improvement measure and check the result. Then move to the next problem. Find more practical decisions for building a store in our guide to five things worth remembering.

Set up measurement in three layers. Sales covers orders, margin, cancellations, and returns. Customer experience includes journey errors, support questions, and completion of key stages. Operations covers fulfilment time, manual corrections, and data discrepancies. Improving one layer should not worsen the other two.

Do not use a universal “good conversion rate” or one average basket-abandonment figure. The result depends on category, price, traffic source, device, and event definition. First establish your own baseline, segment comparable traffic, and check whether a change improves order economics rather than only the number of clicks.

Add a guardrail metric to every experiment. Shortening a form may increase orders but also raise the number of incorrect addresses; a promotion may improve revenue but reduce margin and increase returns. Make a decision only after checking the full effect on the customer and operations, not a single attractive chart.
