On 23 April I was at E-Commerce Warsaw Expo. One of the sessions I'll remember longest was a talk by Nikodem Marciniak from IdoSell - "The Customer's Brain on Autopilot: Why Subscriptions Sell Better Than Price Promotions".

Nikodem was talking about subscriptions in e-commerce - pet food, coffee, cosmetics, meal boxes. A slightly different world from the publishers and education platforms Zevio works with. But the psychological mechanisms he described are exactly the same. And that's why I want to share this.

The decision happens once

This was the central thesis of the whole presentation - and I think there's something really important in it. When a customer signs up for a subscription, their brain doesn't make the decision again with each subsequent payment. It's already a habit, not a choice. Inertia works in the seller's favour.

On top of that come several other psychological mechanisms. 19 PLN a month hurts less than 228 PLN all at once - even though the total is the same or higher. Cancellation is experienced by the brain as a loss, not a saving - and the brain avoids loss. And once a customer builds a product into their daily routine, changing it requires effort - and the brain avoids effort too.

These aren't marketing tricks. It's just how we work.

The paradox that changes everything

One slide stuck with me in particular. Nikodem said: "The easier it is for a customer to leave, the less often they do."

It sounds counterintuitive. But it makes deep sense. When a customer knows they can cancel at any time - no penalties, no complicated procedures - the barrier to entry disappears. They sign up without hesitation. And then they stay, because there's no reason to think about cancelling at every renewal.

We see the same thing with BLIK Recurring Payments. The user can cancel at any time from their banking app. And that's exactly why they so rarely do.

Three moments when you lose a customer

Nikodem identified three critical churn windows - and this is something every subscription business should know.

The first window is the first 14 days. The customer doesn't reach the moment where they genuinely feel the value of the product. CAC is completely wasted - this is the most expensive kind of churn.

The second window is months two, three, four. The novelty effect fades. The customer has either built the product into their routine - or started ignoring it. This moment decides whether they stay long-term.

The third window is the renewal moment. The customer consciously evaluates whether it's worth paying to continue. If the business hasn't acted before this point - there are no arguments for staying.

"A customer doesn't cancel the product - they cancel the belief that it's worth paying for."

That line from Nikodem best summarises the whole session. And it shows that retention isn't about technicalities - it's about managing the perception of value over time.

What does this mean for businesses just getting into subscriptions?

A few things worth keeping in mind.

A subscription is a strategy - not a feature to deploy over a weekend. It requires a considered onboarding process, lifecycle communication, and flexibility on the customer's side.

A pause option instead of cancellation reduces permanent churn by 30-40%. Customers often leave for temporary reasons - a holiday, a budget change, a short-term drop in need. A pause is the answer to that problem.

Subscription data is worth more than data from one-time purchases. You know when a customer is disengaging before they've actually cancelled. That gives you time to act.

And finally - the number that should convince any sceptic: a subscription customer has 3.7 times higher LTV than a transactional one. At 5 times lower retention cost than acquiring a new customer.

A discount buys a transaction. A subscription builds a business. I wrote about this in my previous post - and this talk only confirmed it.

Thanks to Nikodem for a great session. If you get the chance to see him at a future conference - it's worth it.
