UNSUSTAINABLE BUSINESS MODEL – CASE STUDY

At first glance, the model appeared highly promising.

And that is exactly what makes it such an interesting case study.

The Real Problem Wasn’t the Advertising

The main issue was not a lack of demand.

It was not poor communication either.

The problem was the economics of the product itself.

The box was sold for BGN 45 including VAT. After VAT, the net sales value was approximately BGN 37.50.

From that amount, only around BGN 7–10 in profit remained per box before accounting for many of the additional costs associated with growth.

Put simply, the business had very little room for advertising, transaction fees, software, customer service, operational costs, or mistakes.

Even under the most favourable scenario, this represented approximately:

• 18%–27% margin based on the net product price
• 16%–22% based on the final retail price

In theory, those numbers may appear acceptable for certain products.

In practice, however, once you add:

• Advertising costs
• Payment processing and platform fees
• Software subscriptions
• Content production and influencer partnerships
• Operational coordination
• Fulfilment and shipment of large volumes within a short period

The actual profit begins to disappear very quickly.

And that is exactly what happened.

The Additional Challenge – A Limited Sales Window

The business model had another important characteristic: sales took place within a fixed monthly window.

Every month there were:

• 20 days to collect orders
• 10 days to prepare and ship all boxes

This created the need for concentrated marketing pressure within a relatively short period.

Campaigns had to generate awareness, trust, and purchases quickly.

That also meant the cost of inefficient advertising became even more significant because there was limited time available for testing and optimization.

In short, the model required advertising that could deliver results quickly while offering too little margin to sustainably absorb the cost of acquiring customers.

Our Strategy

When we took over the communication, we developed an approach aligned with the product itself and with the way customers buy this type of experience.

1. UGC Unboxing Videos

This became one of the strongest creative directions.

The subscription box was not simply selling a book. It was selling anticipation, emotion, atmosphere, and discovery.

That made UGC unboxing content a natural choice for Paid Ads on Meta.

This type of content worked well because it:

• Showed the complete customer experience
• Communicated value beyond the book itself
• Reduced the distance between the product and the customer
• Created a stronger sense of authenticity

2. Brand-Focused Advertising Visuals

We complemented the video content with advertising visuals designed to strengthen the overall perception of the brand.

The objective was not simply to show what was inside the box.

We wanted to create a broader world around the product — one where the book was not an isolated purchase but part of a complete experience.

3. Influencer Marketing

We incorporated influencer collaborations because the product naturally fitted lifestyle, reading, and aesthetic content.

The logic was straightforward.

When potential customers see the box used and opened in a real environment by someone they already follow and trust, its value becomes much easier to understand.

4. Partnerships With Established Instagram Pages

We also worked with established Instagram pages that could provide faster reach, generate additional interest, and strengthen the social credibility of the product within the short monthly sales window.

What Actually Worked

From a marketing perspective, the project was not a failure.

Quite the opposite.

There were clear signals that the advertising and communication strategy were working.

The product attracted genuine audience interest.

The unboxing creative angle performed well.

The brand positioning strengthened the overall perception of the offer.

Influencer collaborations and Instagram exposure supported both awareness and trust.

The most important fact was this:

The business generated approximately €45,000 in revenue within several months.

This meant that:

• The market responded
• There was real demand for the product
• Advertising successfully generated sales
• The concept itself was commercially interesting

Despite this, total profit for the period was only around €4,000 — approximately 9% of revenue.

Once transaction fees, subscriptions, operational expenses, and other supporting costs were taken into account, the amount of genuinely available profit became extremely limited.

This is where the difference between revenue and actual profitability becomes impossible to ignore.

Why Was High Revenue Not Enough?

This is the core of the entire case study.

Many business owners treat revenue as the primary indicator of success.

But high revenue alone does not prove that a business is sustainable.

When margins are too low, every additional order may look like growth while actually pushing the business closer to operational exhaustion.

If too little remains from every sale, the company becomes dependent on almost perfect efficiency across every part of the operation:

• Advertising
• Logistics
• Production and product sourcing
• Fees
• Partnerships
• Time
• Seasonality

Real businesses are never perfectly efficient.

And that is why the model ultimately proved unsustainable.

The Most Important Lesson

This is not a story about bad advertising.

It is a story about good advertising applied to a business that did not have a sufficiently strong economic foundation.

Before scaling your marketing, you need to know:

• How much you actually retain from every sale
• The maximum CAC your business can afford
• How much growth really costs
• What remains after fees, tools, and operating expenses
• Whether the model remains profitable at higher volumes

Advertising can increase demand.

It cannot create margin where there is none.

What Should Similar Businesses Avoid?

This case study also serves as a warning for subscription, e-commerce, and DTC businesses.

Avoid making one critical mistake:

Do not scale advertising before you know whether your business model has enough margin to support growth.

Before committing to a significant marketing budget, you should understand:

• Net revenue excluding VAT
• Actual profit per product
• Maximum acceptable customer acquisition cost
• Hidden costs across channels, software, fees, and fulfilment
• Whether the model remains sustainable at 1,000 orders, not just 100

If the numbers do not work, advertising is not the underlying problem.

The problem is the mathematics of the business.

Why Do We Publish Case Studies Like This?

Because real marketing is not made up exclusively of success stories.

Real marketing also requires an honest assessment of situations where advertising performs well, but the business itself is not structured to generate enough profit from that success.

That is what separates strategic marketing from simply launching campaigns and waiting for results.

Sometimes the right recommendation is not to increase the advertising budget.

Sometimes it is to reconsider the margins, pricing, offer, cost structure, or the business model itself.
