Ecommerce Subscription Models: Subscribe & Save, Membership, or Both?
Subscriptions promise predictable revenue and higher LTV. But the wrong model for your product will churn faster than it grows.

Subscriptions promise predictable revenue and higher LTV. But the wrong model for your product will churn faster than it grows. Here's how to choose.
The Three Subscription Models
Subscribe & Save (Replenishment)
The customer gets the same product delivered on a recurring schedule at a discount. Best for consumables with predictable usage cycles — supplements, coffee, skincare, pet food.
This is the most natural subscription model because it solves a real problem: the customer runs out and needs more. You're removing friction, not creating a new behaviour.
Curation (Discovery Boxes)
The customer receives a curated selection of products each cycle. Think beauty boxes, snack boxes, book subscriptions. Harder to sustain because novelty fades. Churn rates are highest in this model — once the surprise factor wears off, customers cancel.
Unless you have a genuinely deep and rotating catalogue, curation subscriptions plateau fast.
Membership/Access
The customer pays for perks: free shipping, exclusive pricing, early access, VIP support. This works for brands with wide catalogues and frequent shoppers. The subscription isn't tied to a specific product — it's tied to the relationship.
When Subscribe & Save Works
Subscribe & save is the right model when:
Your product is consumed and needs replacing. Supplements, skincare, coffee, cleaning products, pet food.
The usage cycle is predictable. A 30-day supply means a 30-day subscription. A face serum that lasts 8 weeks means a 60-day cycle.
Customers already reorder. Check your repeat purchase rate. If 20%+ of customers reorder within 90 days, subscription is a natural extension.
The Economics
Typical subscribe & save discount: 10–15% off one-time price. This looks like you're giving away margin, but the maths works differently:
Reacquisition cost drops to near zero. A subscribed customer doesn't need to be re-acquired through paid channels. Their CAC on orders 2, 3, 4+ is essentially $0.
LTV increases dramatically. A customer who buys once at $80 is worth $80. A customer who subscribes for 6 months at $68/month is worth $408.
Cash flow becomes predictable. You know how much revenue is coming next month before you spend a dollar on ads.
Price the discount at or below what it would cost you to reacquire that customer. If your repeat purchase CAC is $15, a 10% discount ($8 on an $80 order) is cheaper than paying to get them back. That's the framework. For the full LTV picture, see our guide on customer lifetime value.
When Membership Works
Membership subscriptions work for brands with:
Wide product catalogues where customers shop frequently
High shipping costs that a "free shipping membership" can absorb
Exclusive products or early access that create genuine FOMO
The membership needs to pay for itself in the customer's mind within 2–3 purchases. If your membership costs $49/year and includes free shipping worth $9/order, it pays for itself after 6 orders. If your average customer orders 8+ times per year, that's compelling.
Churn: The Subscription Killer
Average ecommerce subscription churn is 10–15% per month. That means you lose 10–15% of your subscriber base every single month. If you're not adding subscribers faster than you're losing them, the programme shrinks.
Common churn reasons:
Product accumulation. The customer has 3 unopened boxes. They're receiving faster than they're consuming.
Lack of flexibility. No easy way to skip, pause, or swap products.
Price sensitivity. The initial discount attracted deal-seekers, not loyal customers.
Forgotten subscriptions. The customer didn't realise they were still being charged. This leads to chargebacks and brand damage.
How to Reduce Churn
Make skip/pause/swap easy. One click. No phone call. No guilt trip. Customers who can pause are less likely to cancel outright.
Match the delivery frequency to actual usage. If your product lasts 45 days, don't default to 30-day delivery. Over-delivering is the fastest path to cancellation.
Communicate proactively. Send a reminder before each charge. Show what's coming. Let them modify. Transparency builds trust.
Surprise and delight. Free samples, exclusive content, or a thank-you note in the box. Small gestures remind the customer why they subscribed.
Track retention rate by cohort. If month-3 churn is consistently high, something about the 3-month experience is broken. Diagnose and fix it.
The Tech Stack
On Shopify, the main subscription platforms are:
Recharge: The market leader. Most features, best integrations, handles complex subscription logic well.
Loop: Strong on flexibility and customer portal UX. Good for brands that want a modern self-service experience.
Skio: Focused on reducing churn. Passwordless login, group subscriptions, strong analytics.
All three integrate with Klaviyo for subscription-specific email flows (upcoming charge reminders, reactivation sequences, upsells within the subscription).
Implementation: Start Small
Don't launch subscriptions across your entire catalogue. Start with your top 3 consumable SKUs — the products with the highest natural reorder rate. These are the ones where subscription adds genuine value for the customer.
Offer subscribe & save at 10–15% off on product pages, with subscription as the default selection.
Set the delivery frequency to match actual product consumption (not arbitrary 30-day cycles).
Build a post-subscription email flow that confirms the subscription, educates on how to manage it, and reinforces the value they're getting.
Track subscriber churn monthly. If it's above 15%, diagnose why and fix before scaling.
Subscription revenue should complement your unit economics, not distort them. A subscription programme that acquires subscribers at a loss and churns them at 15%/month is a cash incinerator. One that converts existing repeat buyers into subscribers at a modest discount is a profit machine.
The Bottom Line
Subscriptions work when the model matches the product's natural purchase behaviour. Subscribe & save for consumables. Membership for high-frequency, wide-catalogue brands. Curation only if you have genuinely deep inventory and a strong editorial angle.
Start with subscribe & save on your best-selling consumable SKUs. Price the discount below your repeat-purchase CAC. Make it easy to skip, pause, and cancel. Measure churn monthly. And treat every subscriber as a customer relationship to nurture, not a revenue stream to extract.
