The subscription model is no longer limited to SaaS publishers or streaming platforms. Any business capable of delivering recurring value can structure a subscription offer, provided it masters the metrics that separate a predictable revenue stream from a hemorrhaging subscriber base. The key figures of recurring business dictate the trade-offs: pricing, retention, customer acquisition cost.
LTV/CAC Ratio and Retention Rate: The Two Metrics Driving a Profitable Subscription
A viable subscription relies on a customer lifetime value (LTV) to customer acquisition cost (CAC) ratio greater than 3. Below that, the operating margin is absorbed by marketing expenses before the subscriber even becomes profitable.
The 12-month retention rate is the second structuring indicator. According to data from the SaaS Capital Index included in the 2025 market analyses, well-structured subscriptions exceed 85% annual retention, whereas a traditional e-commerce business must win back the majority of its customers each year. A retention point gained directly impacts LTV without increasing CAC.
We recommend calculating these two ratios from the first month of launch, even on a small sample. Monthly churn tracking allows for the identification of fragile cohorts and intervention before the portfolio deteriorates.
Several resources compile these indicators by sector: consulting the data related to subscriptions and figures on Madam Business allows for comparison of one’s own metrics to the averages observed in the French market.
Subscription Model and Hybrid Pricing: Articulating Usage and Flat Rate
The fixed monthly fee remains the dominant format, but it reaches its limits when actual consumption varies from one customer to another. Hybrid pricing combines a recurring base and a component indexed to usage. This mechanism reduces entry friction (the floor price is low) while capturing the additional value generated by heavy users.
SaaS companies adopting this model show a valuation ratio significantly higher than purely transactional structures. The logic also applies to physical products: a subscription for office supplies or food consumables can incorporate a volume tier with a decreasing rate.
Three Concrete Levers to Structure a Hybrid Subscription Price
- Define a base of services included in the basic package, sufficient to cover the minimal needs of the typical customer and justify the recurring charge.
- Index the variable part to a measurable unit (number of users, volume processed, number of deliveries) so that the customer perceives the correlation between usage and billing.
- Provide a price cap beyond which the price no longer increases, to reassure large accounts and facilitate sales to companies that require a predictable budget.
This type of pricing grid produces a natural retention effect: the customer who consumes more is also the one whose migration cost to a competitor increases.
Cancellation in Three Clicks: Regulatory Constraint and Retention Lever
Since June 1, 2023, any professional allowing online contract subscriptions must offer an accessible, free cancellation process, with an explicit confirmation button. The fine can reach 75,000 euros for a legal entity in case of non-compliance.
This obligation covers all sectors where electronic subscription exists: telecoms, press, energy, digital services. It applies even if the initial contract was signed in-store or by phone.
The temptation to complicate the cancellation process to curb churn is therefore legally risky and strategically counterproductive. A transparent cancellation process improves trust and reduces involuntary churn. Companies that implement “save” offers (discounts, subscription pauses, downgrades) at the precise moment the customer clicks “cancel” recover a significant portion of subscribers about to leave.
Save Journey: The Steps That Work
- Display an intermediate screen offering a temporary pause of the subscription (one or two months), at no cost, before final cancellation.
- Offer a downgrade to a cheaper plan rather than a complete exit, to keep the customer in the active portfolio.
- Collect the reason for cancellation via a short questionnaire (three options maximum) to feed product analysis and continuously adjust the offer.
Net Revenue Retention: The Metric Measuring Organic Subscriber Growth
The gross retention rate does not capture revenue expansion within the existing base. Net Revenue Retention (NRR) incorporates upgrades, upsells, and churn into a single indicator. An NRR above 100% means that recurring revenue is growing without acquiring a single new customer.
We observe that companies with an NRR exceeding this threshold benefit from considerable leverage: each new customer acquired adds to a base that is already generating growth on its own. The marginal cost of growth decreases, profitability accelerates.
To act on NRR, the first lever remains the design of the offer. A subscription catalog with multiple tiers (starter, pro, enterprise) creates a natural upgrade path. The second lever is tracking usage: a customer who underutilizes their plan is a candidate for churn, while a customer who regularly hits the limits of their plan is a candidate for upsell.
Managing a subscription business without tracking NRR is like navigating without a compass. It is this metric, combined with the LTV/CAC ratio and monthly churn rate, that allows one to distinguish a solid recurring model from a subscriber acquisition machine that loses them as quickly as they arrive.
