What is customer churn?
Customer churn is when customers stop doing business with a company, by cancelling a subscription or not renewing a contract. In SaaS it usually means a paying account that leaves, and it is the main counterweight to growth from new customers.
What causes customer churn?
Customer churn usually starts long before the cancellation: the customer stopped getting the result they bought the product for, and nobody noticed in time. The cancellation is the last step of a decision made weeks or months earlier.
The common causes, roughly in the order they show up:
- They never reached the first result. Setup stalled, the data import failed or the one person who championed the purchase got busy.
- Usage stayed narrow. A handful of people use one feature. When budgets get reviewed, the product looks optional.
- The champion left. The person who chose the product moves on, and the replacement has no attachment to it.
- The need changed. The customer's process, team or strategy moved, and the product didn't move with it.
- A better fit appeared. A competitor, or a feature inside a tool they already pay for, does enough of the job.
- Price stopped matching value. Often a symptom of the causes above, not the root.
What are the types of customer churn?
Voluntary churn is a decision: the customer cancels or chooses not to renew. It is the type the causes above explain, and the one product and customer success teams can influence most.
Involuntary churn happens without a decision: a card expires, a payment fails, an invoice lands in an unmonitored inbox. It is fixed with billing operations such as payment retries, reminders before a card expires and a clear way to update details.
Teams also separate full churn (the account leaves) from partial churn (it downgrades or drops seats). Partial churn often comes first, so treat a downgrade as an early warning, not a smaller loss.
How do you measure customer churn?
Count the customers who left in a period and compare them with the customers you had at the start. That ratio is your churn rate, and you can measure it by customer count or by revenue.
The number arrives too late to act on, though. By the time an account shows up in it, the decision is made. Measure it to see the trend, and watch leading signals to change it.
How do you spot customer churn before it happens?
Look for changes in behavior, compared with the account's own history:
- Fewer active users, or active users who stopped doing the core action.
- Key features set up but not used.
- A drop in logins from the admin or champion.
- Support tickets that ask how to export data or cancel.
Here's a typical case. A 40-seat account of a scheduling tool looks fine on logins. Underneath, no one has built a new schedule in three weeks, because the admin who set it up left and the team is working around it in spreadsheets.
Usage data shows the drop. It rarely shows the reason, and the reason is what you need to act. The clearest early warning is what users try to do and can't, described by the users themselves. Foldspace's Conversational Analytics reads every conversation with the Product Agent and shows what each request was for, which conversations ended unresolved and which actions the agent was missing, so a customer success team sees the gap while there's still time to close it. That signal only exists once the agent is live in the product, since it comes from those conversations.
