Should I Start a Subscription Business?
Evaluate subscription business models: from predictable recurring revenue to customer acquisition costs and managing churn.
Published 2 October 2026
The short answer
A subscription business is ideal for founders looking to build predictable, recurring revenue, but it requires a proposition that delivers continuous value over time rather than a one-off solution. The primary challenge is not just acquisition, but preventing churn through constant product relevance and customer engagement. You are not just selling a product; you are managing a long-term relationship where the customer's ongoing satisfaction is the only thing standing between you and a cancellation.
- Predictable recurring revenue makes for a more stable and valuable business
- High pressure to maintain continuous value to justify the ongoing fee
- Customer Acquisition Cost (CAC) vs. Lifetime Value (LTV) is the critical ratio
- Managing 'churn' (lost customers) is the primary driver of long-term success
Subscription models: Box, Software, or Service?
Not all subscriptions are the same, and the operational reality varies wildly between models. A 'subscription box' (physical goods) carries high logistics, shipping, and inventory costs but is tangible and easy for consumers to understand. Software-as-a-Service (SaaS) has very low marginal costs once built but requires significant upfront development and ongoing technical support. A 'service subscription' (like a retainer for design, maintenance, or consulting) sells access to expertise or labour, offering a high-margin middle ground for professional service providers.
The best model depends on your skills and available capital. Physical boxes are easier to start with low technical barriers but are notoriously difficult to scale profitably due to shipping costs, returns, and the 'inventory trap' where you must buy stock months in advance. SaaS is highly scalable and offers the highest valuation multiples if you ever sell, but it requires deep technical expertise or significant investment in developers. Service-based subscriptions (often called 'productised services') are excellent for those transitioning from freelancing to a more scalable model.
You should also consider the 'replenishment' vs 'discovery' vs 'access' models. Replenishment subscriptions (e.g., razor blades or coffee) rely on convenience and price. Discovery subscriptions (e.g., wine clubs or beauty boxes) rely on curation and surprise. Access subscriptions (e.g., Netflix or a gym) rely on the value of the platform or community. Each requires a different marketing and retention strategy. Discovery models, for example, have much higher churn rates as the novelty often wears off after a few months.
The critical math: LTV and CAC
In a subscription business, the most important metrics are Customer Acquisition Cost (CAC) and Lifetime Value (LTV). LTV is the total profit you expect to make from a customer before they churn. CAC is the total amount you spend on marketing and sales to get that customer through the door. For a subscription business to be sustainable, your LTV must be significantly higher than your CAC—ideally significantly higher or more to account for overheads and reinvestment.
Many subscription startups fail because they focus on 'total subscribers' rather than 'profitable subscribers'. If it costs you £100 in Facebook ads to acquire a customer who pays £10 a month but cancels after four months, you are losing money on every sale. You must have a clear understanding of your 'payback period'—how many months it takes for a new customer to cover their own acquisition cost. If your payback period is longer than your typical customer lifespan, your business is effectively a 'leaking bucket'.
Understanding your margins is equally vital. A £50/month physical box might only have a £10 profit margin after COGS (Cost of Goods Sold), shipping, and packaging. In contrast, a £50/month digital subscription might have a £45 profit margin. The digital model allows you to spend much more on CAC while still achieving a healthy LTV/CAC ratio. Evans advises founders to model their unit economics rigorously before committing to a specific price point or marketing channel.
Managing and reducing customer churn
Churn is the 'silent killer' of subscription businesses. If you lose a portion of your customers every month, you have to replace a significant number just to stand still. High churn is usually a sign that the product is not delivering enough continuous value or that the onboarding process is failing to help customers get results quickly. There are two types of churn: voluntary (the customer decides to leave) and involuntary (the customer's credit card fails).
Reducing voluntary churn requires constant engagement. You must proactively show the customer the value they are getting. This might involve 'usage reports', new feature announcements, or exclusive community content. In the physical box world, it means ensuring every box feels like it's worth more than the subscription price. If a customer hasn't used your software or opened your box in two months, they are a 'zombie subscriber' who is highly likely to cancel the moment they look at their bank statement.
Involuntary churn is often overlooked but can account for a significant portion of lost revenue. Credit cards expire, are reported lost, or hit their limits. Using modern billing platforms that automatically retry failed payments and send 'dunning' emails (reminders to update card details) can instantly recover lost revenue. Evans suggests that reducing churn by even a small percentage is often more profitable and easier than increasing new sales by a much larger margin.
Pricing and billing infrastructure
Subscription pricing is a science that involves psychology and economics. You must find the balance between a price that is low enough to encourage sign-ups but high enough to cover your costs and allow for profit. Tiered pricing (e.g., Bronze, Silver, Gold) is the industry standard because it allows you to cater to different segments of the market—from budget-conscious individuals to high-value corporate clients—and provides a clear 'upgrade path' for customers as their needs grow.
Your billing infrastructure must be robust, automated, and compliant. Manually invoicing subscribers every month is not scalable, leads to payment delays, and is prone to human error. Use established platforms like Stripe, Paddle, or specialised subscription management software (like Chargebee or Recurly) to handle recurring payments, failed cards, and VAT compliance (especially if selling internationally). Don't forget that as a UK business, you must comply with 'Strong Customer Authentication' (SCA) requirements for recurring payments.
Consider the 'commitment' factor in your pricing. Offering a discount for annual billing (e.g., '12 months for the price of 10') is a powerful way to improve cash flow and lock in customers, reducing churn. However, it also means you are receiving that cash upfront and must manage it carefully to ensure you can still service the customer for the full year. Annual plans are great for 'lumpy' cash flow needs, while monthly plans provide a steady, predictable income stream.
The challenge of 'Content Fatigue' and operations
For content or box-based subscriptions, the biggest operational challenge is the 'content treadmill'. You must produce something new and high-quality every single month (or week). This requires a highly organised production process and a deep well of ideas. If the quality of one month's offering dips, you will see a spike in churn. Many founders underestimate how much work it takes to keep a subscription 'fresh' after the first six months.
Logistics in physical subscriptions is another major hurdle. You are essentially running a miniature e-commerce and logistics business. You have to manage suppliers, warehouse space, pick-and-pack labour, and shipping partners. A delay in shipping or a high rate of damaged goods will lead to immediate cancellations and a damaged reputation. Scaling a physical subscription requires moving from 'packing at the kitchen table' to using a 3PL (Third Party Logistics) provider, which introduces new costs and management challenges.
Customer support is also a significant overhead. Subscription customers expect high levels of service, especially if they are paying a premium recurring fee. You will deal with questions about billing, shipping, product usage, and cancellations. Providing fast, professional support is a key retention tool. If a customer finds it impossible to cancel or get a simple question answered, they will not only leave but may also post negative reviews that damage your future acquisition efforts.
Building a community or utility
The most successful subscriptions aren't just about the product; they are about being part of something or providing a necessary tool. If your subscription provides a 'utility' that the customer relies on daily (like accounting software or a specific professional network), they are much less likely to cancel. If it's a 'luxury' or 'entertainment' item, it's often the first thing to be cut when household or business budgets are tight.
Building a community around your subscription can significantly improve retention. When customers feel connected to other members or to the brand itself, the subscription becomes a part of their identity. This is particularly effective in niche hobbyist markets or professional peer groups. However, community management is a significant time commitment and should be factored into your running costs. A thriving community needs moderation, engagement, and regular events or content to stay active.
Focus on 'stickiness'—features or benefits that make it harder for a customer to leave. For software, this might be the data they have stored in your system. For a service, it might be the deep understanding you have of their business. The more 'integrated' your subscription is into the customer's life or work, the higher their lifetime value will be. Evans advises looking for ways to move from a 'nice-to-have' discovery box to a 'can't-live-without-it' utility or community.
Validation: The cheapest way to test your subscription idea
Do not build a full software platform or buy a warehouse full of stock to test a subscription idea. The cheapest validation test is to launch a simple landing page that describes the offer and asks for a small deposit-backed signup or a 'waitlist' registration. If you can get 50 people to commit their email and a small deposit for a future launch, you have a proven interest.
You can then deliver the first few months 'manually' (e.g., using off-the-shelf tools like Typeform for data collection and manual Stripe links for payment) to test the logistics and the customer's appetite for the ongoing fee. This is often called 'Wizard of Oz' testing—where the front end looks automated, but the back end is manually managed by the founder. Only once you see that people stay beyond the second or third month should you invest in the full infrastructure.
Use Evans Business Builder to map out your initial 'Minimum Viable Subscription' (MVS). Your goal during validation is not to make a profit, but to prove the 'retention' hypothesis: do people actually want this enough to pay for it more than once? If you have total churn in month two, your business model is broken, and no amount of fancy software will fix it. Use this early feedback to pivot your offering before you've spent significant capital.
