Subscription model

What it means

A subscription model is a business model in which the customer pays a recurring fee, monthly or annually, for access to a product or service instead of a one-off purchase. It is typical of software companies selling SaaS, media and streaming services, but also accounting firms or service businesses charging a flat fee.

The main advantage for the company is predictable income. Instead of starting from zero each month, it has a stable base of recurring revenue measured by MRR. Growth then depends on how many customers join, how many leave and whether existing ones pay more.

Besides MRR, the key metrics are churn, the share of customers cancelling, and LTV, the total value of a customer over the relationship. The model only works when LTV clearly exceeds the cost of acquiring a customer.

How it works in practice

For subscription clients, our main task is booking annual payments correctly. If a customer pays a year in advance, the revenue belongs to the months in which the service is delivered. The unused portion at year-end is recorded as deferred income.

For VAT, the tax point for recurring supplies follows the rules for partial and continuous supplies, or receipt of an advance payment. The billing system should be able to issue invoices with the required details and the correct supply date for each period.

When selling to consumers, the rules on consumer contracts apply: clear information about price, commitment length, automatic renewal and how to cancel. Cancelling should be as easy as signing up.

What to watch out for

A common mistake is recording an annual subscription as a full year’s revenue in the month of payment. Profit is inflated in one period and missing from the next, distorting the picture for banks and investors.

A free trial or freemium model that attracts many users but few payers is another risk. If the company does not track conversion to paid plans and churn after the trial, it can grow in user numbers while losing money.
