Damon Boswell and Ashley Boswell make the case that a 5% increase in retention can lift profits 25-95% — and the retention strategy that actually delivers it.
There is a number Ashley Boswell writes on the whiteboard in nearly every growth strategy engagement: a 5% increase in customer retention can lift profits by 25% to 95%. The figure, well established in business research, is one of the most counterintuitive findings in all of business strategy — and it is the one most leadership teams consistently ignore. The reason is simple: acquisition is exciting and retention is invisible. New customers are a story. Retained customers are a baseline. Yet the baseline is where the profit actually lives.
The economics are straightforward once a leader stops to look at them. Acquiring a new customer is, on average, five to seven times more expensive than retaining an existing one. Damon Boswell puts it in concrete terms: every dollar spent chasing a new customer is a dollar that could have produced a higher return if it had been spent keeping a current one. A business that optimizes only for acquisition is running a leaky bucket — pouring new customers in the top while existing customers drain out the bottom. The net level rises slowly, if at all, and the cost of filling it keeps climbing.
Customer success is the discipline that has emerged to close that gap, and Ashley Boswell is clear that it is not a renamed support function. Traditional customer support is reactive — it waits for something to break. Customer success is proactive — it works to make sure the customer achieves the outcome they bought the product to achieve. The distinction matters because a customer who is succeeding does not churn, and a customer who is not succeeding will churn no matter how good the support is once they complain.
Damon Boswell structures a retention strategy around three pillars. The first is onboarding — the first 30 to 60 days after a customer signs determine whether they will ever reach the value they were promised. A customer who does not reach their first meaningful outcome quickly is a customer who is already halfway out the door. The onboarding is not a welcome email; it is a guided path to the first result, with a human checking in at the moments where customers typically stall.
The second pillar is proactive engagement. Ashley Boswell builds customer health scores — a small set of signals that indicate whether a customer is on track, at risk, or already disengaging. Usage frequency, support ticket sentiment, and time since last meaningful interaction are the kinds of signals that flag a problem weeks before a cancellation does. When a health score drops, the customer success team reaches out before the customer reaches for the exit. This is the work that turns retention from a hope into a system.
The third pillar is the customer journey map — the deliberate design of every touchpoint a customer experiences from purchase through renewal. Damon Boswell walks leadership teams through their own customer journey and asks them to identify the friction points, the silent periods, and the moments where the customer is left to figure things out alone. Removing those friction points is, in his experience, the single highest-leverage retention move a business can make. Customers do not leave because the product is bad. They leave because the experience of being a customer is harder than it should be.
The measurement layer is what makes the strategy defensible. Ashley Boswell tracks retention rate, churn rate, and customer lifetime value together, because no single metric tells the whole story. A high retention rate with a declining lifetime value means the business is keeping customers but losing the relationship — they stay, but they spend less. A low churn rate with a long silent period before cancellation means the business is losing customers it did not realize were unhappy. The metrics, read together, are the early-warning system.
Customer retention is not a soft initiative. It is the most profitable growth lever most businesses have, and it is the one most consistently underfunded. Damon Boswell and Ashley Boswell help leadership teams build the retention system — onboarding, proactive engagement, journey design, and measurement — that turns existing customers into the foundation of sustainable growth. That is the work, and it is the work Blueprint Business Advisors was built to do.
