Selling subscriptions online: models, tools and keeping customers

Subscriptions are appealing for an obvious reason: predictable revenue. Instead of winning every sale from scratch, you win a customer once and they keep ordering. Coffee roasters, pet food brands, skincare companies and software businesses all use the model.

But a subscription is a relationship, not a single transaction. It needs the right model, reliable billing and a way for customers to manage things without calling you. Get those right and subscriptions can steady your business. Get them wrong and you get a stream of failed payments, angry emails and cancellations.

Choose a subscription model that fits

Most subscription businesses fall into a few patterns:

• Replenishment: products people run out of, such as coffee, vitamins or filters, delivered on a schedule.
• Subscribe and save: an optional discount for customers who choose a recurring order instead of a one-time purchase.
• Curated boxes: a surprise or themed selection each month.
• Memberships and access: perks, content, software or services for a recurring fee.

Pick the one that matches how your customers already buy. If people reorder your product every few weeks, replenishment is a natural fit. If they buy once a year, forcing a subscription will mostly create cancellations.

Pick the right tools

If you sell physical products on Shopify, start by looking at Shopify's own Subscriptions app and the subscription apps in the Shopify App Store. They plug into your existing checkout, products and customer accounts. WooCommerce has subscription extensions that do a similar job.

If you sell software, services or memberships, a billing platform such as Stripe Billing is often a better fit. It handles recurring invoices, plan changes, trials and proration, and you build your own sign-up and account experience around it. That takes more development, but gives you full control.

Plan for billing problems

Cards expire, get replaced after fraud or hit their limits. Every subscription business deals with failed payments, and many of them are recoverable if you try again at the right time.

Good billing tools handle this for you. Stripe's Smart Retries feature, for example, automatically retries failed subscription payments and lets you set how many attempts to make over a chosen period. Stripe can also email customers when a payment fails, with a link to update their card. Whatever tool you use, check that it supports automatic retries, reminder emails and an easy way for customers to update payment details.

Understand why customers leave

Churn is the share of subscribers who stop paying. It comes in two kinds, and they need different fixes.

• Involuntary churn happens when a payment fails and never gets recovered. The customer did not mean to leave. Retries and card update reminders address this.
• Voluntary churn happens when a customer decides to cancel. Common reasons include too much product piling up, price, or simply losing interest. Better flexibility and a better product address this.

Ask a short question when people cancel. Even a single dropdown with a few reasons will tell you more than guessing.

Also look at when people cancel. If many leave right after the first or second order, the problem may be expectations set at sign-up, such as unclear delivery frequency or portion sizes. If they leave after several months, product fatigue or price is a more likely cause.

Give customers real self-service

Customers expect to manage subscriptions themselves. Shopify's Subscriptions app, for example, lets customers edit payment details, change their shipping address, skip upcoming orders, and pause or cancel from their customer account. Whatever you use, those basics should be available without contacting you.

Skip and pause options are especially valuable. Many customers who cancel really just have too much stock on hand. Letting them skip a month keeps them as customers.

Getting started

Start small. Offer a subscription option on a handful of products your customers already reorder, with a modest discount and clear terms. Show the full recurring price and frequency before checkout, and send a reminder before each renewal if your tool supports it.

Our honest recommendation: use an established subscription app or billing platform rather than building recurring billing from scratch. Spend your custom effort on the customer experience around it, and watch failed payments and cancellation reasons closely for the first few months.
