The Business Model Canvas
Nine blocks that hold an entire business on one page. Below: what each block actually asks, a worked example filled in end to end, and the real canvas — editable right here, in your browser, with no account and nothing uploaded. Then the part most guides skip, which is how to adapt it to a business that does not look like the textbook one.

What it is, and what it is for
The Business Model Canvas is a one-page description of how an organisation creates, delivers and captures value. It was developed by Alexander Osterwalder and Yves Pigneur, and it replaced the forty-page business plan for a simple reason: nobody compares two forty-page plans, and everybody compares two canvases.
That comparison is the whole point, and it is why the one-page constraint is not a stylistic choice. When the model sits on a single surface, the blocks argue with each other in front of you. A channel you cannot afford shows up as a contradiction between channels and cost structure rather than as an opinion someone holds in a meeting. A value proposition that no named segment asked for looks like what it is: an orphan.
The layout is also not arbitrary. The right side — segments, relationships, channels, value propositions — is about value delivered. The left side — resources, activities, partners — is about value created. Revenue sits under the right, costs under the left, and the business works when the first is bigger than the second. Read that way, the canvas is not nine boxes; it is one sentence.
The nine blocks, and the trap in each
These are the nine prompts exactly as they appear in the canvas that opens below — not a paraphrase of it. Each block gets the question it really asks, and the specific way it gets filled in badly.
1. Customer segments
"Who exactly. Name one segment you deliberately do not serve."
The trap: writing "small businesses" or "everyone who needs X". A segment you cannot name a real person inside is not a segment. The second half of the prompt is the useful half — naming who you refuse forces a real boundary, and a canvas whose segment block excludes nobody will produce a value proposition that excites nobody.
2. Value propositions
"The promise, in the customer's words. What they stop suffering — not what you built."
The trap: listing features. "Real-time collaboration" is something you built; "we stop losing the latest version" is what they stop suffering. If the sentence would not survive being read aloud to a customer, it belongs in key activities, not here.
3. Channels
"Where they discover you, and where they buy. Rarely the same place."
The trap: collapsing discovery and purchase into one line. They are usually different, and the gap between them is where most businesses leak. Splitting this block in two is the single most common useful adaptation of the canvas.
4. Customer relationships
"How you win, keep and grow them. Self-serve, or hand-held?"
The trap: describing the relationship you would like rather than the one your price supports. Hand-holding at a $9 price point is a cost structure problem that shows up two blocks later — which is exactly the contradiction the canvas exists to surface.
5. Revenue streams
"What people actually pay for, how often, and at what price."
The trap: naming the product instead of the payment. "Subscriptions" is not a revenue stream; "$29/month per seat, billed annually, average 6 seats" is. The three parts of the prompt — what, how often, how much — are three separate answers, and skipping "how often" is how one-off revenue gets mistaken for recurring.
6. Key resources
"What you own that makes it possible: people, code, audience, data."
The trap: listing everything you use. A key resource is one whose loss would stop the promise from being delivered. Office software is not a key resource; the audience you spent four years building is.
7. Key activities
"What must happen every week for the promise to hold."
The trap: writing a job description. The filter is the promise: if the value proposition is "always up to date", then the weekly activity is updating — not recruiting, not accounting. Activities that support no stated promise are overhead, and seeing them named here is useful information.
8. Key partners
"Who you rely on, and what each one brings. Name the one you could not replace."
The trap: listing suppliers. The prompt's second sentence is a risk register in disguise: the partner you could not replace is a dependency, and writing its name down is often the most uncomfortable minute of the exercise.
9. Cost structure
"What you pay whether or not you sell, and what grows with every sale."
The trap: one undifferentiated list. The prompt splits fixed from variable on purpose, because that split is what tells you whether scale helps you or hurts you. A business whose costs grow in step with every sale is a business that does not get easier at ten times the size, and this block is where that becomes visible.
A worked example, filled in end to end
Abstract canvases teach nothing. Here is one filled for a small B2B SaaS — an invoicing tool for independent architects — with the level of specificity the blocks actually ask for. Note how many blocks name a number or a proper noun.
Customer segments
Independent architects and 2–5 person practices billing project fees in stages. Not served: large firms with an in-house finance person — they already have ERP and buy on procurement cycles we cannot survive.
Value propositions
"I stop chasing stage payments." Invoices go out on schedule tied to project milestones, and late ones chase themselves.
Channels
Discovery: the two architecture practice-management newsletters, and search for "architect invoice template". Purchase: self-serve card checkout on the site.
Customer relationships
Self-serve, with one 20-minute onboarding call for annual plans only — the call pays for itself at $290, not at $29.
Revenue streams
$29/month per practice, or $290/year. Roughly 60% choose annual. No per-invoice fee — it punishes the customers doing best.
Key resources
The milestone-billing engine, and the accountant relationships that vouch for us in a profession that buys on referral.
Key activities
Keeping tax rules current across the three countries we serve. If this stops for one quarter, the promise is dead.
Key partners
Stripe (payments), and the accounting-software API we sync to. Irreplaceable: that API — losing it would strand every existing customer's books.
Cost structure
Fixed: two salaries, hosting, the tax-rules data subscription. Variable: payment fees at ~2.9%, and support, which rises with seats rather than revenue.

Adapt it to your business — this is the part that matters
Almost every guide stops at "here is the canvas". But the nine blocks were derived from studying businesses that mostly sell a product to a buyer who uses it, and plenty of real businesses do not work that way. A canvas you cannot bend is a canvas you fill in once, politely, and never open again.
So the useful question is not "how do I fill in the standard canvas" but "what does my business need this canvas to say". Four adaptations that come up constantly:
- Two-sided marketplaces need two right-hand sides. Supply and demand are different segments with different value propositions, channels and relationships — and forcing them into one column hides the fact that you are running two businesses that must both work.
- Split channels into discovery and purchase. Mentioned above, and the most broadly useful change of all. Two blocks, because they are two decisions.
- Free users are a segment, not a footnote. If your model has a free tier, it has a segment that generates cost and no revenue, and it deserves its own block rather than an asterisk — otherwise cost structure quietly lies.
- Non-profits invert the bottom. Funders and beneficiaries are different people, so "revenue streams" and "customer segments" no longer line up. The canvas still works; the labels have to change.
This is the practical reason to keep a canvas as a document rather than a picture. In the editor above you can add a block, split one in two, rename them, or duplicate the whole canvas to compare two versions of the model side by side — which is the exercise the canvas was invented for and the one a printed template makes impossible.
Which canvas should you actually use?
The Business Model Canvas has two close relatives, and picking the wrong one wastes the session. The short version:
| Use | When | Why |
|---|---|---|
| Business Model Canvas | The business already runs, or you must show how it will pay for itself | It is the only one of the three with cost structure facing revenue streams |
| Lean Canvas | Nothing is built yet and the real risk is whether the problem is real | Swaps the operational blocks — which you cannot honestly answer yet — for problem, solution, key metrics and unfair advantage |
| Value Proposition Canvas | The model holds but the promise is not landing | Zooms into two blocks only — segment and value proposition — as jobs, pains and gains against your offer |
All three, plus SWOT, AARRR, the 1-Page Marketing Plan and eight more, are on the frameworks page.
Common questions
In what order should I fill it in?
Right side first. Customer segments, then value propositions, then channels and relationships, then revenue. Only then the left half — resources, activities, partners — and cost structure last. The left describes what it takes to deliver a promise, so filling it first means designing an operation before you know who it serves.
How long should this take?
A first pass is thirty to ninety minutes, and it should feel unfinished. The value is in the second pass three weeks later, when four blocks change because you spoke to customers in between. A canvas that never gets edited was decoration.
Can I use the Business Model Canvas commercially?
The canvas itself is published by Strategyzer AG under Creative Commons BY-SA 3.0, which permits commercial use with attribution and share-alike on derivatives. The attribution travels inside the template here, at the foot of the canvas, so a copy you export or share keeps it. What you write in your own canvas is yours.
