An ecommerce platform with subscriptions as a first-class product type

Selling a one-time product is a single transaction. Selling a subscription is the start of a relationship that lasts months or years. The platform has to handle a steady drumbeat of renewals, the inevitable failed payments (Stripe data: roughly 6–11% of recurring charges fail on the first attempt), the customer who wants to pause for a month, the one who upgrades mid-cycle and expects a prorated charge, the one who downgrades, the one who cancels and the one who comes back. Each of those flows is a feature — and on most platforms, each of them is a third-party app.

The compounding cost is what drives subscription merchants away from generic platforms. A typical Shopify subscription business stacks: Shopify Basic at £29/mo + Recharge at £60/mo + Klaviyo for retention emails at £45/mo + Loop for returns at £25/mo. That's £159/mo before you've sold anything, and Recharge takes a 1% transaction fee on top of Shopify's payment processing fee. By the time a £30/mo subscription customer is on their third renewal, they've cost you almost £15 in compounding platform fees — half the revenue gone before COGS.

Axnify rolls the subscription primitives into the core platform. The product type is `subscription`. The billing interval, trial period, auto-renewal flag, upgrade pool and grace period are first-class fields on the product, not config in an add-on app. The customer portal where buyers manage their active subscriptions is part of the default storefront theme. Failed-payment dunning emails are configurable in the admin under Notifications. The only fee on top of standard Stripe processing is the platform fee on your tier (1.5% on Starter, dropping to 0% on Enterprise).

Use this checklist when evaluating Axnify, Shopify+Recharge, Cratejoy, Subbly, WooCommerce Subscriptions and the rest. Most platforms tick three or four boxes; the gaps are where you'll lose revenue 6 months in.

First, native subscription support without an add-on. If the platform's pitch is 'install [app name],' that's an extra subscription, an extra transaction fee and an extra surface to debug when something breaks. Add the app's monthly cost to the platform cost before comparing.

Second, smart dunning. Ask how the platform retries failed payments. The answer should include a multi-attempt schedule (3-5 attempts over 14-21 days), escalating customer notifications, and suspend-on-final-fail. 'Email the customer once and cancel' is not enough — it sets your involuntary churn to ~10% monthly which compounds devastatingly over a year.

Third, prorated upgrades. A customer wants to upgrade mid-cycle. Does the platform charge the prorated difference for the remaining period? Or does it cancel the old sub, refund the unused portion and create a new sub? The latter is messy on the books, breaks attribution and confuses customers who see a refund and a new charge on the same day.

Fourth, customer self-service. The portal where customers manage their own subscriptions is the single biggest lever on support cost. If your platform doesn't have one, every pause / cancel / upgrade / change-card flow lands in your CS queue. That's a hidden cost of running on the wrong platform.

Fifth, mixed-cart support. Subscription businesses also sell one-time products (gift add-ons, sample boxes, one-off upgrades). The platform should handle subs + one-time in a single cart and a single checkout. Two-cart workarounds bleed conversion.
