The subscription model is usually sold with slogans about “stable revenue”. Slogans explain nothing. Here is what actually changes in a store’s unit economics — and where subscriptions lose.
What we are comparing
Take one store and two ways of selling the same product. The conditions are identical:
- average order — ₴800;
- margin — 35%, so ₴280 per order;
- customer acquisition cost (CAC) — ₴400;
- advertising budget — ₴40,000 a month, so 100 new customers.
One-off sales
A hundred new customers give a hundred first orders: ₴28,000 of margin against ₴40,000 of spend. The first month runs at a loss — which is normal, that is how acquisition works.
Some of those customers come back. Assume a realistic 30% return once more within a year, and half of those once again. That is about 145 orders from a hundred customers over a year: ₴40,600 of margin against ₴40,000 of spend.
The model breaks even over a year. To grow you have to top the budget up every month, and every rise in advertising costs lands directly.
Subscription
The same hundred customers, the same acquisition cost. The frequency is every three weeks, so about 17 orders a year if the customer stays.
Not all of them stay. Take monthly churn of 8%: 92 subscriptions are active at the end of the first month, 85 at the end of the second, and so on. Over a year, a hundred customers produce roughly 1,000 orders.
- Margin: 280 × 1,000 = ₴280,000
- Acquisition spend: ₴40,000
The difference is not that subscriptions are “better”. The difference is that you paid for the customer once and sold to them seventeen times instead of one and a half.
Payback time
A figure more important than LTV if you are growing on your own cash.
With one-off sales, a ₴400 CAC is only ₴280 repaid on the first order. The rest comes back with the second — months later, and only from the 30% who returned at all.
With a subscription the second order arrives in three weeks, reliably. CAC is fully repaid in about six weeks, and every order after that is profit. This directly determines how fast you can raise the budget without a cash-flow gap.
Churn is the main lever
In a subscription model the whole economy rests on one number. Compare:
| Monthly churn | Average lifetime | Orders per customer |
|---|---|---|
| 15% | ~6.7 months | ~9 |
| 10% | 10 months | ~14 |
| 8% | ~12.5 months | ~18 |
| 5% | 20 months | ~29 |
Cutting churn from 15% to 8% more than doubles revenue per customer on exactly the same advertising budget. That is why working on churn pays better than working on traffic.
The cheapest way to reduce churn is to give the customer an alternative to cancelling. A large share of people press “cancel” not because they no longer want the product but because a surplus has built up or a holiday is coming. Pause, skip one delivery and change frequency rescue precisely those subscriptions — but only if they are two clicks away rather than an email to support.
When a subscription makes no sense
An honest list, because these cases come up more often than subscription articles admit.
A product with no consumption cycle. Furniture, electronics, tools, jewellery. There is no moment at which the product runs out, so there is no reason for regularity.
A purchase that involves choosing each time. Clothing, books, gifts. People want to choose, not to receive. Curation works here — and that is a different model with different churn and a need for a content team.
A very low order value. If the margin on an order is smaller than the cost of delivery and handling, regularity only multiplies the loss. The answer is bundles, not more frequent deliveries.
Unreliable stock. If you cannot guarantee availability every month, a subscription becomes a source of disappointment rather than retention.
A hybrid is a perfectly good answer
The most common mistake is thinking you have to choose. You do not. Most stores have part of their range with an obvious consumption cycle and part without.
The workable answer: keep one-off purchases for the whole catalogue and enable subscriptions on the items where they make sense. The same cart, the same checkout, the same warehouse. Subscriptions give you a predictable base; one-off sales give you the peak.
That is exactly how Neocarts works: the cart serves both, and the 5% fee is charged only on subscription transactions. One-off purchases cost nothing.
