How to reduce churn and keep more of your customers.

Churn quietly cancels out growth. A monthly revenue churn of 4% sounds small, but compounded over a year it means losing roughly 39% of the revenue you started with. Your sales team then has to replace that before it can grow the business at all. Small improvements in retention make a large difference to lifetime value, as the unit economics calculator will show you.

Separate the types of churn

• Logo churn: the number of customers who leave.
• Revenue churn: the recurring revenue lost, including downgrades. This matters more if customers vary in size.
• Voluntary churn: the customer chose to leave.
• Involuntary churn: payment failed and was never recovered. In card-billed products this can be a surprisingly large share, and it is the easiest to fix.

Find out why customers leave

1. Ask at cancellation. A short exit question with fixed options (too expensive, missing feature, switched to competitor, business closed or changed, not using it, other) plus a comment box.
2. Talk to churned customers. A 20-minute call with a few customers who left this quarter will tell you more than the form. Ask what changed, when they first had doubts and what would have made them stay. Use the same approach as customer discovery interviews.
3. Look at cohorts. Use cohort analysis to see whether churn is concentrated in a sign-up month, a segment, an acquisition channel or a plan.
4. Write down the top three causes by revenue lost, not by number of mentions.

Fix the cause, not the symptom

Run renewals as a process

For annual contracts, start renewal conversations well before the date. A rule of thumb: a value review at 90 days out, a renewal proposal at 60, and the signed renewal by 30. A value review covers the outcome agreed at onboarding, the evidence it has been reached, what the customer wants next year and any risks. If the customer wants to cancel, offer alternatives that suit them: a pause, a smaller plan or a shorter commitment. Never make cancelling deliberately difficult; it damages trust and, for consumers, can breach consumer protection rules. See the Competition and Markets Authority for current guidance.

A worked example

Tallyhouse, a fictional Leeds tech startup, sells bookkeeping software to sole traders on monthly card billing. Monthly revenue churn was around 5%. Exit surveys pointed to price, but when the team looked closer, about a third of lost revenue came from failed card payments that were never chased. A further large share came from customers who had never connected a bank feed.

Tallyhouse added payment retries and reminder emails, and made bank connection the first step of onboarding with personal help for anyone stuck. Within two quarters, monthly churn fell to around 3%, without any change to price.

Common mistakes

• Accepting the stated reason at face value. “Too expensive” often means “not valuable enough”.
• Offering discounts to every leaving customer, which trains customers to threaten to leave.
• Measuring an average churn rate that hides one bad segment.
• Waiting for the renewal date to find out whether the customer is happy.

What to measure

• Monthly logo churn and revenue churn, voluntary and involuntary separately.
• Gross revenue retention over 12 months.
• Churn by cohort, segment and cancellation reason.
• Renewal rate for annual contracts, and the share with a value review held on time.
