Keeping eCommerce sales profitable can feel like using a stairmaster whose speed is controlled by an invisible demon you inexplicably offended. The constant calibration of advertising costs, order volume, and returns management leaves you stressed, confused, and liable to be blindsided by a sudden shift in pace.
The D2C subscription model promises an escape from that machine: orders that keep arriving with no fresh effort required. The relief is almost unthinkable, like being told you never have to look at your bank balance again. But it's also exactly the kind of prospect that warps founders’ judgement.
The scenario is probably familiar: founders look at their subscription data, calculate a tidy customer lifetime value (LTV), and start spending aggressively to acquire more subscribers, on the assumption that a high customer acquisition cost (CAC) will sort itself out once the recurring revenue kicks in and finally calls off the demon.
We call this the LTV delusion: a premature belief that early purchase trends will hold at scale. It's often fuelled by dubious data, like the claim that loyal customers are worth 22 times more than other customers.
The study defines "loyal" customers as those who place 13 or more orders, which means the finding essentially amounts to "customers who order more generate more revenue." But even if subscribers really are an order of magnitude more valuable, the harder question remains: can D2C founders afford to win subscription customers at a loss?
Recurring revenue does genuinely change the unit economics for categories that build habits (like supplements) or reward experimentation (like booze.) Subscribers can compound your marketing investment and even improve your chances with investors.
The question is whether that's true broadly enough to justify chasing it at any cost.
We brought together James Kouhry (CEO of Zendbox and serial founder) and Peter Fairhurst (Head of Sales at Zendbox) to debate that question and share their experience helping countless D2C brands launch and scale subscriptions.
This piece is part of a series Zendbox has produced analysing the key dilemmas D2C founders face as they scale.
James starts by asserting that eCommerce growth is zero-sum. “Your brand is competing with seven competitors with a longer financial runway” he says. “If your first order has to be profitable, other companies will win by being less efficient and earning their investment back over subsequent months.”
He likens it to tying one arm behind your back. “If you have no financial wiggle room, there’s just less you can do,” he says. “It’s famously hard to measure influencer ROI, for example. Brands with strict first-order profitability might shy away from that, which means you miss a net gain in the name of ‘financial prudence.’”
That discipline is essential when you’re operating on a shoestring, he says. But it soon becomes a growth bottleneck:
While Peter agrees an upfront investment to drive subscriptions can accelerate growth, he points out a unique quirk that makes the ROI of eCommerce subscriptions harder to project.
The “lose-and-recoup” approach works for Software-as-a-service (SaaS) or magazine publishers who can expect relatively stable order rates. Even with high subscriber churn, they can at least calculate how much runway is required before the average customer becomes profitable.
eCommerce has a very unpredictable payback period—the duration it takes to recover the customer acquisition cost and generate profit. “People pause and change subscription dates all the time,” Peter says. “What looks like a four-month payback period can easily spread to eight.” That’s a very different equation for brands that probably have limited ramp time during which they can swallow losses.
eCommerce companies often struggle to calibrate the risk/reward of earning subscribers at a loss, or determine exactly how much they can afford to lose upfront. Founders often chase scale based on faulty assumptions and end up building an acquisition system—and ultimately, a business model—that won’t last long enough to turn into a sustainable company.
“It feels like you can iron out the creases later,” Peter says. “But what you build while you scale just is your company. There’s no ‘before and after’ photo.” He argues that’s the central point founders should bear in mind: subscriptions aren’t a magic bullet for slow growth; they’re a strategic direction that might work or not, depending on the product and how it’s sold.
James argues subscriptions aren’t just about recurring revenue; plenty of products without official subscription programs rely on repeat custom and often use the same “lose-and-recoup” strategy.
What’s different is the frame subscriptions place around your product. Rolling subscriptions make repeat purchase automatic and remove friction, but they also signal that the product is intended to be used as part of a routine.
“You can often improve conversions just by adding a ‘recommended’ or ‘most popular’ frequency of order,” James says. “It implies a correct or optimal way of using the product that reassures the customer.”
Importantly, the model has become ubiquitous enough that not offering a subscription option sends a signal to consumers. “You’ve either decided people don’t want the product every month,” James says, “or you’ve revealed a terrible lack of awareness about your audience. Both lead to lost sales.”
James follows this up by asserting that there are certain categories that are almost by definition ‘subscription products.’ “If you’re selling something like coffee or workout supplements, subscriptions ought to be the default,” he says. “Retention issues are likely a problem with the product itself, not the stickiness of the subscription model.”
“That’s true,” Peter says. “But it’s also true that some products just aren’t subscriptions.”
This underpins an important point for Peter: the subscriptions that work—and can justify an upfront loss—treat subscription as the product, not just a purchase option.
“Even if your product is an obvious ‘replenishment’ purchase, the subscription deal has to deliver extra value,” he says. Not just through discounts or free gifts, but through a complete experience.
“You really have to look beyond the first month or two,” James agrees. “Inertia is powerful, but it won’t keep most people subscribing through most brands’ payback period. And consumers are far more active about managing their unused subscriptions now.”
James encourages founders to think about their subscription-market fit, just as they would when developing products. “You’re not just stuck with a static product,” he says. “You can calibrate the price structure, gifts, and membership perks to align with what your specific customers want.”
Creativity plays a surprising role here. “We’re seeing far more variability in how brands price and frame their subscriptions,” Peter explains. “There used to be this idea that subscriptions are either ‘Subscribe and Save’ plays, curated products, or a membership deal. Now brands can pull on all of those levers in inventive ways to find the offer that connects with their customers.”
That experimentation is essential to making the economics of subscriptions work. Get the subscription-market fit right, and James insists far more brands will be able to justify the ‘lose-and-recoup’ strategy. “It’s just like developing a killer product people actually want,” he says. “Once you’ve nailed it, a lot of your problems go away.”
Subscriptions that really work are used consistently, Peter says. You see less pausing or moving the subscription date, which makes the payback period easier to anticipate. And the overall churn is reduced, because even if people do subscribe initially with a “F—It, Why Not?” mentality, they are won over by the experience.
Getting there can require experimentation though, which brings us back to the central problem: can brands afford to invest upfront in scaling subscriptions?
Yet the answer now appears clearer: yes, as long as there’s a good reason to think your product has the potential for a strong subscription-market fit.
Products that help customers build virtuous habits, such as health and wellness, are the obvious example. But it’s also possible to develop a strong subscription service with any product that can become a ritual that customers integrate into their lives—be that self-care, improved fitness, or a monthly indulgence. And sometimes the solution is simply to ask.
“Don’t be afraid to invite feedback,” Peter tells founders. “Your subscription can evolve, just like your products.” If you realise churn is too high, it’s worth running tests or asking customers what would make them continue subscribing. But that goes beyond the standard “exit interview” form they fill in when subscribing.
“Customers often really like sharing their opinions,” James says. “They just don’t like narrow forms that feel extractive, or like they’re trying to block their decision to unsubscribe.” Frame the feedback as helping other customers or explicitly state that the feedback will be used to redesign the subscription, and you’re likely to see far higher participation.
And that is the essence of all successful eCommerce subscriptions, according to James: building a real sense of shared investment between you and your customers. Brands that see subscription as a way to justify overspending on marketing or fixing faulty unit economics miss that—and their founders never find their way off that demon-operated stairmaster.
Sometimes, but the decision should rest on evidence that the subscription itself appeals to customers, not on an LTV figure projected forward from a handful of early orders.
If your category rewards routine and your competitors have deeper pockets, insisting on first-order profitability can cap your growth. If you have no read on whether people will stay subscribed past the first few cycles, an upfront loss is just a loss with optimistic accounting attached.
The obvious one is churn eating the returns you spent to acquire. Less obvious are the operational costs: forecasting inventory against a subscriber base that pauses and reschedules, managing failed payments, and running a fulfilment cadence that has to hit reliably every cycle rather than once.
Discounting is a further drag, since the same percentage comes off every order rather than the first. And an acquisition engine that only works while it is subsidised is difficult to unwind once the business is built around it.
There is no dependable benchmark, and treating any published figure as one is risky. The calculation itself is simple enough: acquisition cost divided by contribution margin per order tells you how many orders you need.
What makes eCommerce awkward is that the interval between those orders is not fixed. Customers pause, skip, and push delivery dates back, so a modelled timeline routinely stretches well beyond the plan. Model a slower version of your forecast and check whether your cash position survives it.
Subscription-market fit is James Kouhry (CEO of Zendbox and serial founder) coinage for how closely your subscription offer matches the way customers actually want to buy: the frequency options, the price structure, the perks, and how easily people can adjust their plan.
It is distinct from product-market fit, because a product people like can still be wrapped in a subscription they have no reason to keep. You can usually spot good fit in the behaviour: steady order cadence, little pausing, and churn that settles after the first few cycles instead of climbing. Like the product, it can be tested and improved.
