How to test a business model in 15 minutes (and understand whether it works or is just «fueled by enthusiasm»)
1. Gross profit and fixed costs
When it comes to a quick check of a business model, the first thing we’re interested in is a simple question: how much money is left after fulfilling a single order – before tax and without accounting assumptions.
Take a single order and deduct all direct costs of fulfilling it per customer – the product or service, delivery, commissions, returns and marketing.
What remains is the gross profit per order (or, in the language of operational logic, the contribution of a single order to the business). Now compare this amount with fixed costs: rent, salaries, office space, software, and management. If the gross profit does not, in principle, cover the fixed costs, no increase in revenue will save the business. You will be scaling not profit, but loss.
If every new order does not make the business ‘stronger’ and the gross profit does not cover the fixed costs, then the business model is not working.

2. CAC and Margin
The cost per lead (the first customer contact/conversion/expression of interest) is irrelevant today. This is the reality of business in 2026.
One of the most common sources of self-deception in business is the belief in ‘cheap marketing’. This has not been the case for a long time. The biggest expense today is marketing. The same product now generates different profits. This depends directly on the cost of the traffic source - the channel from which the customer came. One channel puts you in the red, whilst another delivers an excellent margin. What matters is the customer acquisition cost (CAC) and how much money the customer brings in.
If CAC exceeds the value of the first order, the business isn’t growing. It’s simply redistributing funds to the market, platforms and contractors. Turnover increases, the shop is swamped with work, and the business goes into the red.
This problem is quickly identified - it takes just three minutes to check - but it saves you from months of working at a standstill.
3. Repeatability and the sustainability of the business model
If a business is forced to start ‘from scratch’ every time, its model remains vulnerable, regardless of the sector. In IT, this might manifest as a constant search for new users; in services, as one-off projects with no follow-up; and in manufacturing, as irregular contracts with no repeat business.
Recurring operations provide predictable revenue and reduce dependence on new customers, tenders or deals. If, however, revenue comes solely from new orders, the business is effectively operating under constant stress, even if it appears to be growing on the surface.
A lack of repeatability in a business model makes it fragile and difficult to manage.

Over the years it has spent working in consulting and finance, LLC "EIFOS HUB" has encountered the same situation time and again. The client’s business appears to be successful, but a careful analysis of the figures reveals that there is no system in place, and the results are simply a fortunate coincidence or a combination of temporary factors. Everything relies on personal connections, the loyalty of certain employees, or the owner’s charisma.
We observe the same symptoms in the IT sector, manufacturing, retail, traditional sales and service companies. It is not about the sector, but the outward appearance. A company may show growth, but profits are only really growing on paper, in terms of figures. Yet there is no increase in cash flow. And talking about business development in such a situation is pointless.
What should you focus on first and foremost? Do you understand where and how profit is generated? In this article, we won’t be revealing any secrets: it takes just 15 minutes to understand whether your company’s business model is effective or whether everything that is happening is merely a façade.

4. The cash gap and operational reality
Can a business operate on its own cash flow? Even where the business case appears sound, companies often face a chronic shortage of cash (the cash gap) - the time lag between when a company incurs costs and when it receives payment. In manufacturing, this manifests itself in inventories and long cycles; in services, in deferred payments; and in IT, in high upfront costs with delayed monetisation.
As a result, a company may show a profit but constantly require additional capital injections. Growth in such conditions does not ease the situation but increases the strain on working capital. The more actively the business operates, the more money it temporarily ‘eats up’.
5. The ‘money–product–money’ path
Where and how is profit generated? At which stages is it lost? This looks different across various sectors. In IT, it is the path from attracting a user to a paid subscription; in services, from a contract to the actual volume of work performed; in manufacturing, from the purchase of raw materials to a paid delivery. But the logic is always the same: money must pass through the product or service and return to the business with a profit.
If this picture is missing, management is replaced by gut feelings. Decisions are made ‘backwards’, where the main priority is to avoid downtime in production, the team or the infrastructure. Turnover and external activity take precedence over the economics of the process.
What does model analysis offer?
Validating a business model isn’t about complex formulas or perfect reports. It’s about taking an honest look at how growth relates to money. Do they stay in the business, or do they disappear faster than they appear? It is this question, rather than the industry or scale, that determines whether the model works - or is merely fuelled by enthusiasm.
If, after validating your business model, you find that processes are running on a wing and a prayer, and money is leaving faster than it’s coming in, we can help. LLC "EIFOS HUB" audits your current business processes and analyses your business model, offering concrete solutions for optimisation, increased efficiency and cost reduction.
