Subscription Billing

Subscription billing is the set of processes a business uses to charge customers at regular intervals for an ongoing service. It covers the definition of price plans, the creation of invoices for each period, the collection of payment, and the handling of upgrades, cancellations and failed payments. It is used by software companies, streaming and media services, telecoms providers, gyms, insurers and membership organizations.

The term describes the commercial and accounting side of a subscription. The movement of money is handled through recurring payments on cards, bank debits or wallets. A subscription business therefore runs two connected systems: a billing system that decides who owes what and when, and a payment system that collects it.

A plan sets the price, the billing interval and what the customer receives. Common models are listed below, and many businesses combine them.

• Flat rate. One price per period for a defined package.
• Per seat. The price is multiplied by the number of users or licenses.
• Tiered. Several packages at rising prices, or a unit price that changes with quantity, as in tiered pricing.
• Usage-based. The charge depends on consumption measured during the period, covered under usage-based billing.
• Hybrid. A fixed platform fee plus charges for usage above an included allowance.

Plans may also include a free trial, a setup fee, discounts or coupons, and a minimum contract term. Annual plans are usually billed in advance at a lower effective monthly price.

Each subscription has a billing cycle that begins on the day the customer signs up or on a fixed calendar date. At the start of each cycle, for plans billed in advance, the system generates an invoice, applies taxes and credits, and attempts payment using the stored method. Usage charges are billed in arrears, once the period's consumption is known.

Changes in the middle of a cycle need adjustment. When a customer upgrades, adds seats or downgrades, the system calculates a partial charge or credit for the remaining days, a process called proration. Cancellations may take effect immediately with a refund or at the end of the paid period, depending on the terms.

For consumer subscriptions the usual method is a card kept on file. The first payment is authenticated by the customer, and later charges are submitted by the business as a merchant-initiated transaction. Bank debits are common for utilities, insurance and business customers, and require a mandate. Larger business customers often pay invoices by bank transfer on agreed terms.

Card details go out of date when cards expire or are replaced. Businesses reduce the resulting failures with network tokens and a card account updater, services through which the card networks supply new details automatically.

A share of renewal charges fails each cycle, for reasons such as insufficient funds, expired cards or issuer fraud controls. Customers lost this way did not choose to leave, and the loss is called involuntary churn. The process for recovering failed payments is dunning: the system retries the charge on a schedule, sends reminders asking the customer to update their details, and eventually suspends or cancels the service. Well-designed retry timing and messaging can recover a large part of failed renewals.

Cash collected is not the same as revenue earned. Under accounting standards such as IFRS 15 and its United States equivalent, a business that bills a year in advance records the cash as deferred revenue and recognizes it month by month as the service is delivered. Billing systems keep the schedules needed for this.

The standard performance measure is monthly recurring revenue, the normalized monthly value of all active subscriptions, along with its annual equivalent. Related figures include churn rate, expansion revenue from upgrades and customer lifetime value.

Subscriptions attract consumer protection rules because customers can be charged repeatedly without acting. Card networks require clear disclosure of terms at sign-up, a reminder before a free trial converts to a paid plan in many cases, and an easy way to cancel online. Laws in several jurisdictions, including automatic renewal statutes in US states and consumer law in the European Union and United Kingdom, set similar requirements. Merchants with unclear terms or difficult cancellation face high dispute rates, which can lead to penalties from their acquirer.

Small businesses often use the subscription features built into their payment processor. Larger ones use a dedicated billing platform that connects to several processors, tax engines and the accounting system. Some sell through a merchant of record, which takes on billing, tax collection and payment handling in return for a share of sales.
