The business model canvas explained, block by block

The business model canvas is a one-page template that describes how an organisation creates, delivers and earns from value, using nine blocks: customer segments, value propositions, channels, customer relationships, revenue streams, key resources, key activities, key partners and cost structure. It replaces a long business plan with a sheet you can sketch in an afternoon and test piece by piece. The business model canvas tool lays out the classic grid, and this guide explains each block with an example.

What the canvas is

The canvas was developed by Alexander Osterwalder from his doctoral research on business models and popularised by the book Business Model Generation (2010), written with Yves Pigneur. It is published by Strategyzer under a Creative Commons licence, which is why so many free versions exist. The layout has a logic: the right-hand side is about customers and revenue, the left-hand side is the operational engine and its costs, and the value proposition sits in the middle connecting the two.

The nine blocks

• Customer segments — the specific groups you create value for.
• Value propositions — the problem you solve or need you meet for each segment, and why you rather than the alternative.
• Channels — how customers find out about you, buy and receive what you offer.
• Customer relationships — self-service, personal help, community, subscription.
• Revenue streams — what customers pay for and how: one-off sales, subscriptions, fees, licensing.
• Key resources — the assets you need: people, equipment, intellectual property, money.
• Key activities — what you must do well to deliver.
• Key partners — suppliers and allies who do things you should not do yourself.
• Cost structure — the biggest costs, and which are fixed and which vary with volume.

The order to fill it in

Start with customer segments and value propositions, because everything else depends on who you serve and what you promise them. Then channels, relationships and revenue, which complete the customer side. Only then move left to activities, resources, partners and costs. The tool stacks the blocks in this order on a phone screen for that reason. Write one short point per line; if a block needs a paragraph, it is probably two ideas. For the middle block, the value proposition generator helps turn a vague promise into a sharp one.

A worked example

Imagine an invented start-up that rents and looks after plants for small offices for a monthly fee.

• Customer segments: offices of 10 to 80 people without a facilities team; co-working spaces.
• Value propositions: a greener office with zero effort; plants replaced free if they die; one monthly price.
• Channels: direct outreach to office managers; referrals; a website with a quick quote form.
• Customer relationships: a named plant carer who visits every two weeks; a WhatsApp line for requests.
• Revenue streams: monthly rental per plant; one-off installation fee; event hire.
• Key resources: plant stock, a van, trained carers, a nursery space.
• Key activities: visiting, watering and swapping plants; route planning; sales.
• Key partners: wholesale growers, a pot supplier, a van leasing company.
• Cost structure: staff time (the biggest cost), plant replacement, van, nursery rent.

Laid out together, the risks become visible. Staff time scales with visits, so profit depends on dense routes: ten clients in one business park beat ten spread across the city. That insight changes the channels block, towards targeting one area at a time. To test whether the numbers work, the break-even calculator shows how many plants on rental cover the fixed costs, as explained in How to calculate your break-even point (and what it doesn't tell you).

Common mistakes and limits

• "Everyone" as a customer segment. If you cannot picture a specific buyer, the rest of the canvas will be vague too. A buyer persona helps.
• Treating entries as facts. Every block is an assumption until customers confirm it. Mark which ones you have evidence for.
• Features in the value proposition. "App with dashboard" is a feature; "know your cash position every morning" is value.
• Filling it once. The canvas is meant to be redrawn as you learn.

The canvas does not capture competition, timing or the financial detail an investor or lender will want. For a start-up still searching for a problem worth solving, Ash Maurya's Lean Canvas swaps several blocks for problem, solution and key metrics.
