How to fill in the Business Model Canvas: 9 blocks, example and template

The Business Model Canvas is a visual tool that shows on a single page how a business creates and delivers value and earns revenue from it. Unlike a business plan running to dozens of pages, the canvas can be drafted in a few hours, discussed easily within the team and updated as you learn. That is why it is one of the tools most used by founders, incubators and investors. In this guide we cover the canvas's nine blocks, the questions to ask in each, a worked example, how it differs from the Lean Canvas and how to validate it.

Why use the Business Model Canvas?

• You see the whole at a glance: The links between customer, value, channel, revenue and cost become clear.
• It makes assumptions visible: Every box is a hypothesis to test.
• It is fast: A draft can be produced in one meeting.
• It creates a shared language: You talk with your team, partners and mentors within the same frame.
• It compares alternatives: You can try different business models for the same idea side by side.

The canvas does not fully replace a business plan, but it is the best way to clarify thinking before writing one. For a detailed plan see the business plan guide.

Structure of the canvas

The canvas has nine blocks, usually laid out like this: the right side focuses on customers and value (the revenue side), the left side on operations and efficiency (the cost side). In the middle is the value proposition, the centre of everything.

1. Customer segments

Question: For whom are we creating value? Who are our most important customers?

Group customers by needs, behaviours and willingness to pay. It can be a mass market, a niche, multiple segments or a two-sided platform (buyers and sellers). Starting with at most 1–2 main segments on one canvas gives clarity.

Tip: Use concrete definitions like "private health clinics with 3–20 staff working by appointment" instead of "small businesses". See audience and persona analysis.

2. Value proposition

Question: What value do we deliver to the customer? Which problem do we solve, which need do we meet?

Value can come from novelty, performance, customisation, design, price, cost reduction, risk reduction, accessibility or convenience. Write a separate value proposition for each segment.

Tip: Do not write a feature list; write the outcome the customer gets. Instead of "cloud-based booking system", "removes the 2 hours a day spent taking bookings by phone".

3. Channels

Question: How do we reach customers and deliver value to them?

Channels cover five phases: awareness, evaluation, purchase, delivery and after-sales. Website, social media, sales team, partners, marketplaces and physical stores are example channels. See SME digital marketing and the B2B sales process.

4. Customer relationships

Question: What kind of relationship do we establish and maintain with each segment?

Forms include personal assistance, a dedicated account manager, self-service, automated service, community or co-creation. The relationship type also directly affects your cost structure. See customer loyalty and community-led growth.

5. Revenue streams

Question: For what value, how and how much do customers pay?

Product sales, usage fees, subscriptions, licensing, commission, advertising and renting are common revenue models. Also state whether pricing is fixed or dynamic. See subscription business model and pricing psychology.

6. Key resources

Question: What resources do we need to deliver the value proposition?

Physical (equipment, warehouse), intellectual (brand, software, patents, data), human (expert team) and financial resources. Mark which one differentiates you from rivals. See the IP guide.

7. Key activities

Question: What are the most important things we must do for the business model to work?

Such as production, software development, problem solving (consulting), platform management, marketing and sales. Write only the "must-have" activities here.

8. Key partnerships

Question: Who are our key suppliers and partners? Which activities do we leave to them?

Partnerships are formed to cut cost, reduce risk or acquire resources: suppliers, distribution partners, technology providers, strategic alliances. See partnership agreements and corporate partnerships.

9. Cost structure

Question: What are the most important costs in our business model? Which resources and activities are most expensive?

Fixed costs (rent, salaries), variable costs (product, shipping, commission), economies of scale and scope. State whether you are cost-driven (lowest cost) or value-driven (premium experience). See the financial model and CAC and LTV.

Example: clinic booking software

| Block | Content | |---|---| | Customer segments | Private dental and physiotherapy clinics with 3–20 staff | | Value proposition | Online booking that cuts phone traffic, automatic reminders reducing no-shows | | Channels | Website, industry associations, field sales, partnerships with clinic consultants | | Customer relationships | Free onboarding support, self-service panel, email and live support | | Revenue streams | Monthly subscription per clinic, extra fee for SMS packs | | Key resources | Software platform, health-sector knowledge, support team | | Key activities | Product development, set-up and training, sales | | Key partnerships | SMS and payment providers, cloud infrastructure, industry associations | | Cost structure | Developer salaries, cloud and SMS costs, sales and marketing |

The critical assumptions in this example are: Are clinics willing to pay a monthly subscription? Do reminders really reduce no-shows? Is field-sales cost reasonable relative to customer lifetime value?

How it differs from the Lean Canvas

The Lean Canvas is a version of the Business Model Canvas adapted for startups. It replaces some blocks with:

• Problem: The customer's top 1–3 problems
• Solution: The simplest solution for each problem
• Key metrics: Numbers showing success; see the North Star metric
• Unfair advantage: An edge that cannot easily be copied

If you are very early and still validating the problem, the Lean Canvas may fit better; if you are analysing a working business, the classic canvas is more comprehensive.

How to build the canvas, step by step

1. Prepare a large sheet or digital template. Use sticky notes so you can change things easily.
2. Start with customer segment and value proposition. If these two do not fit, filling the other boxes is pointless.
3. Complete the right side: Channels, relationships, revenue.
4. Complete the left side: Resources, activities, partners, costs.
5. Check the links: Does every channel serve a segment? Is every cost tied to an activity?
6. Mark assumptions: Mark every unproven note in a different colour.
7. Draw alternative canvases: Try different segments or revenue models.

Validating the canvas

The canvas is a set of guesses; its real value appears when tested.

1. Pick the riskiest assumption (usually customer segment, value proposition or willingness to pay).
2. Design a small experiment to test it: customer interviews, a landing page, pre-sales. See idea validation and customer interviews.
3. Update the canvas based on the result.
4. Keep each version of the canvas dated; it shows your learning process.

When to use the canvas

• When evaluating a new idea
• When analysing an existing business and looking for growth opportunities
• When considering a pivot; see the pivot guide
• Before an investor or grant application; see the pitch deck and grant application
• To build a shared understanding within the team

Common mistakes

• Filling boxes independently: The canvas's power lies in the links between blocks.
• Writing too generally: Phrases like "everyone" or "quality service" carry no information.
• Treating assumptions as facts: The canvas is a list of hypotheses.
• A one-off exercise: The canvas should be updated as you learn.
• Squeezing all segments onto one canvas: Draw a separate canvas per segment if needed.
• Forgetting competitors and the market: Support the canvas with competitor analysis and a SWOT analysis.

FAQ

How long does it take to build a canvas? A first draft takes 1–2 hours; the real value lies in updates made through tests.

Do investors ask for a canvas? They may not ask directly, but the clarity of the canvas shows in your pitch deck.

Does the canvas replace a business plan? Largely yes at an early stage; a detailed plan may be needed for bank loans or some grant applications.

Conclusion

The Business Model Canvas is a powerful tool that clarifies your idea on one page, aligns the team and shows the assumptions to test. Start with the customer and value proposition, check that the blocks fit together and keep updating the canvas with real customer data.
