E-business, E-commerce and E-marketing Definitions for ACCA SBL

Updated 11 October 2026 · Fact-checked

**E-business** is the use of digital technology across all of an organisation's activities, internal and external. **E-commerce** is the buying and selling of goods and services electronically, a subset of e-business. **E-marketing** is the use of digital channels to promote products and manage customer relationships. In SBL, show the scope, then apply it to the case.

Understand E-business, E-commerce and E-marketing Definitions

Start with the widest term. E-business means using information and communication technology to run and improve the whole organisation. It covers the value chain: procurement, operations, logistics, HR, finance, sales and service. It includes internal systems such as an intranet or ERP, and external links with suppliers, customers and partners.

E-commerce is narrower. It is the electronic buying and selling of goods and services, plus the supporting transactions such as online ordering, payment and delivery tracking. A website shop is e-commerce. Using an electronic system to place orders with suppliers is also e-commerce, on the buying side. Every e-commerce activity is part of e-business, but e-business is more than selling online.

E-marketing is the use of digital media and technology to achieve marketing aims. It includes a website, search engine marketing, email, social media, online advertising and customer data analysis. Its goal is to attract, understand and keep customers. It can support e-commerce by driving sales, but a firm can use e-marketing without selling online, for example a local clinic that advertises on social media and takes bookings by phone.

A simple way to remember the link: e-business is the whole, e-commerce is the transaction part, and e-marketing is the promotion and relationship part. Examiners reward you for using the right term in the right place, and for tying it to the organisation in the scenario.

Also know the direction of the link. Buy-side e-commerce deals with suppliers, such as e-procurement. Sell-side e-commerce deals with customers. Internal e-business covers staff and processes, such as shared systems, workflow and knowledge sharing.

Key rules to remember

E-business: E-business = digital technology applied to all organisational activities (internal and external); The widest term. It includes e-commerce and e-marketing.
E-commerce: E-commerce = electronic buying and selling (buy-side and sell-side) and related transactions; A subset of e-business. Focus is the transaction.
E-marketing: E-marketing = use of digital media and data to attract, understand and keep customers; Focus is promotion and relationships, not only sales.
Relationship: E-commerce and e-marketing are both parts of e-business; E-marketing may support e-commerce but can exist without online sales.

How to solve E-business, E-commerce and E-marketing Definitions questions

Use this method for any SBL requirement on definitions, scope or application of e-business terms.

1Read the requirement and note the verb: define, explain, distinguish, assess or recommend.
2Define each term the question asks for in one clear sentence.
3Show how the terms relate: e-business is the whole, e-commerce and e-marketing sit inside it.
4Pick the scenario facts that show digital activity: sales channels, supplier links, internal systems, marketing channels.
5Classify each fact against the right term, and say whether it is buy-side, sell-side or internal.
6Apply it: say what the organisation does now and what gaps or opportunities remain.
7Conclude with a clear recommendation or judgement, linked to strategy and the value chain.
8Check that you have used the scenario names and figures, and earned professional skills marks through clear, structured communication.

Quickest way: Whole, transaction, promotion

When to use it: Use when time is short and the task asks you to distinguish or classify the three terms.

Write three short labels: E-business = whole organisation, E-commerce = transactions, E-marketing = promotion and customers.
Underline each scenario activity and tag it with one label.
Add one line on how they link, then one applied point per term.
Finish with a brief recommendation.

Common mistakes in E-business, E-commerce and E-marketing Definitions

Treating e-business and e-commerce as the same thing.
Both involve technology and websites, and everyday speech blurs them.
Fix: State that e-commerce is only the buying and selling part. Add internal and supplier activities to show e-business is wider.
Describing e-marketing as only social media posts.
Students think of the most visible channel.
Fix: List the range: website, search, email, advertising, social media and customer data. Link it to attracting and keeping customers.
Ignoring buy-side and internal activities.
Students focus on the customer-facing website.
Fix: Scan the scenario for procurement, stock systems, HR and finance. Classify them as e-business activities.
Giving definitions with no application.
Definitions feel safe and quick to write.
Fix: After each definition, add a sentence using the organisation's own facts. Application earns the marks.
Saying e-marketing requires online sales.
Students link all digital activity to selling.
Fix: Remember that firms can promote online and sell offline. Use an example from the scenario where possible.

Worked examples

Example 1

A regional furniture retailer has a website where customers order and pay, uses an electronic system to order stock from suppliers, and runs email campaigns to past customers. A director says, 'We only do e-commerce.' Explain whether this is correct.

Show the solution

Define e-commerce: electronic buying and selling, including related transactions.
Identify the e-commerce activities: online customer orders and payment (sell-side) and electronic stock ordering (buy-side).
Define e-marketing: using digital channels and data to attract and keep customers.
Identify the e-marketing activity: email campaigns to past customers.
Define e-business: digital technology across all activities. The firm uses it for sales, procurement and promotion, so it is wider than e-commerce.
Conclude and add a point: the director is not correct. To reach full e-business, the firm could extend digital use to internal areas such as stock, HR and finance.

Answer: The statement is not correct. The firm does e-commerce (online sales and electronic ordering from suppliers) and e-marketing (email campaigns). Together with any internal digital systems, these make up e-business, which is wider than e-commerce alone.

Example 2

A professional services firm uses a client portal for secure document sharing, an intranet for staff knowledge, and search advertising to attract new clients. It does not sell services online. Classify these activities and advise whether it is engaged in e-commerce.

Show the solution

Client portal and intranet: digital technology used in operations and service. These are e-business activities, not e-commerce, as no buying or selling occurs through them.
Search advertising: digital promotion to attract clients. This is e-marketing.
Check for transactions: the firm does not sell services online and no electronic purchase is described, so there is no sell-side e-commerce on the facts given.
Note any buy-side activity: none is described, so do not assume it.
Advise: the firm practises e-business and e-marketing. It could consider e-commerce, such as online booking and payment for standard services, if this fits its strategy and risk appetite.

Answer: The firm is engaged in e-business (client portal, intranet) and e-marketing (search advertising). On the facts given, it is not engaged in e-commerce because no buying or selling is done electronically. Online booking and payment could be a future option.

Exam tips

Define the terms briefly, then spend most of your time applying them to the scenario. Application carries the marks.
Use the exact scenario facts and names to show professional skills and commercial awareness.
Show the hierarchy clearly: e-business includes e-commerce and e-marketing.
If asked to assess or recommend, add benefits and risks and link them to strategy. Do not stop at definitions.
Plan your answer in short labelled points so the marker can follow it, even when time is tight.

E-business, E-commerce and E-marketing Definitions: frequently asked questions

What is the difference between e-business and e-commerce?

E-business is the use of digital technology across the whole organisation, including internal systems and links with partners. E-commerce is only the electronic buying and selling part. All e-commerce is e-business, but not all e-business is e-commerce.

Is e-marketing the same as e-commerce?

No. E-marketing promotes products and manages customer relationships using digital channels. E-commerce completes transactions online. A firm can do one without the other.

How do I use these definitions in an SBL answer?

Give a short definition, then link it to facts in the scenario. Say which activities fit each term and what the organisation should do next. Marks are mainly for application and judgement.

Do I need to know buy-side and sell-side e-commerce?

Yes, it helps you classify activities accurately. Buy-side covers electronic purchasing from suppliers. Sell-side covers electronic sales to customers.
