Checking Your Business Model on One Page: Customers, Value, Revenue, Costs

Why it pays to check your own business model

Most owners can describe their offering in a few sentences. It gets harder when the question is which service carries the profit and which eats it up. Often the business model has grown over years: one service was added because a customer asked for it, a price was set because a competitor dictated it. What results works, but nobody has recently looked at it as a whole.

This guide answers one question: How do you check your business model on one page so that weak points become visible and decisions can be derived from it? To answer it, we first clarify the term, then present the Business Model Canvas as a mental model and reduce it to four questions. We then weigh what the tool achieves and where it is overrated, and work through the check with a worked example.

A business model that exists only in the owner’s head can be neither checked nor improved.

What is a business model? The term explained

A business model describes how a company creates value for customers and how it secures part of this value as revenue for itself. It is not the same as a strategy. The strategy says where a business wants to go and how it stands out from the competition. The business model describes how the business works today.

How vague the term is can be seen in the review by Zott, Amit, and Massa (2011). They found at least 1,177 academic articles on the subject since 1995 and noted that research has not agreed on a definition. Many authors use their own terms, which are hard to compare. Even so, the authors identify common lines: the business model views the company as a system, includes partners beyond the company’s boundaries, puts activities at the center, and explains both how value is created and how it is captured. Spieth, Breitenmoser, and Röth (2025) count more than 1,700 further publications on business model innovation since 2016 alone.

For an owner, this disagreement is good news: there is no single correct form. What matters is that both sides are on the page, the value for the customer and the numbers for the business.

The mental model: the Business Model Canvas

The best-known tool is the Business Model Canvas, which Alexander Osterwalder and Yves Pigneur presented in 2010 in their book “Business Model Generation.” It organizes a business model into nine fields on one sheet: customer segments, value proposition, channels, customer relationships, revenue streams, key resources, key activities, key partners, and cost structure. The right half of the sheet describes the market, the left half the business, and the value proposition sits in the middle.

For a small business, nine fields are often more than a first look requires. They can be condensed into four questions that together cover the two sides Zott, Amit, and Massa (2011) emphasize: value creation and value capture.

The check in four steps

The page takes an afternoon, ideally with two or three people from the business who have different perspectives, such as sales, delivery, and accounting.

1. Customers

   Write down the two to four customer groups that carry most of the revenue, with their share. Which of these groups are growing, which are shrinking?

2. Value

   For each group, state in one sentence which problem you solve. Test the sentence against the last three won and the last three lost orders.

3. Revenue

   Note what each group pays for: hour, flat fee, unit, contract. What share of revenue comes in on a recurring basis, and what share must be won anew every year?

4. Costs

   Separate fixed costs from direct costs and determine the contribution margin per service. Note which partners or people the business depends on.

For the customer side, the profile from the guide defining target customers helps. For value, the question of what the business wants to be known for is useful, covered in the guide sharpening your positioning. Which pricing models are possible on the revenue side is compared in pricing models compared.

A worked example: where the money is really made

An example business with freely chosen numbers plans and installs systems for commercial customers and offers maintenance, spare parts, and consulting. The page first shows the shares of revenue: new systems 60 percent, maintenance 20 percent, spare parts 15 percent, consulting 5 percent. The owner sees himself as a system builder. Only the cost question changes the picture.

It follows from the figures that new systems bring 60 percent of revenue but only just under 40 percent of total contribution margin. Maintenance and spare parts together bring 35 percent of revenue and just over half of the contribution margin. The business therefore earns its money mainly after installation. This raises different questions than before: is every new system sold with a maintenance contract? How many systems in the installed base have none? What contribution margin per order tells you is explained in the guide contribution margin per order.

Two readings: thinking tool or box-filling exercise?

The Canvas has many supporters and a number of critics, and both have arguments.

Research supports both sides. Dreșan Pop, Chiorean, and Bacali (2025) propose a revised Canvas for small and mid-sized companies that combines customer fields and adds triggers and extent of change, and they themselves name limits in analytical depth. Mejia-Duque and Guerrero-Alvarado (2025) describe in a case study of a Colombian manufacturer that the Canvas alone does not provide systematic problem-solving and had to be combined with another method. I therefore consider the second reading a justified warning, not an argument against the tool. The Canvas organizes thinking. The figures and the customer conversations derived from them do the checking.

What the page shows beyond the individual case

Once you have created the page, you usually come across one of three weak points. First, a mismatch between revenue and contribution margin as in the example, which points to prices, scope of services, or recurring revenue. Second, a dependency, for example on a major customer, a supplier, or the owner. Third, a value proposition that does not differ from the competition.

Each of these weak points has its own answer. A mismatch leads to the question of which services to expand and which to cut back. How recurring revenue arises in a traditional business is described in the guide building recurring revenue. A dependency calls for a plan, as described in the analysis of concentration risk. A weak value proposition is a question of positioning.

The limits of the method belong here too: one page depicts the current state. It does not say how the market, technology, or competition will change. That is why it belongs in an annual rhythm, as proposed in the guide the annual strategy check.

Conclusion and next step

To the guiding question: the business model can be checked on one page if four questions are answered with figures: who the business works for, which problem it solves, what the customer pays for, and what delivery costs. The Business Model Canvas is a useful grid for this, but only contribution margin per service and per customer group turns the page into a check. Weak points become visible where revenue and earnings diverge.

1. Take a blank sheet and write the four questions one below the other.
2. Answer each in no more than three lines with at least one figure.
3. Determine the contribution margin per service from last year’s figures.
4. Mark the largest gap between revenue share and contribution margin share and decide which question to clarify first.

The page is not a result but a beginning. Its value lies in the fact that afterward, people in the business talk about the same picture.
