Using this insight, they implement targeted engagement campaigns at months 12-15 when they notice early warning signs of potential churn. They also adjust their pricing model to offer incentives for annual subscriptions rather than monthly payments. As a result, they extend their average customer life to 27 months, significantly increasing their customer lifetime value and reducing the pressure to constantly acquire new customers to maintain revenue. This allows them to allocate more resources toward product development rather than acquisition marketing, creating a positive cycle of improved product quality leading to even longer customer retention. ## You should also read: [Average Order Value](/glossary/average-order-valuex)[Average Revenue Per Account](/glossary/average-revenue-per-accountx)[Average Revenue Per User](/glossary/average-revenue-per-userx)[Average Selling Price](/glossary/average-selling-pricex)[Awareness Buying Stage](/glossary/awareness-buying-stagex)[B2B Buyer Intent Data](/glossary/b2b-buyer-intent-datax)[B2B Data](/glossary/b2b-datax) ## Why teams choose Derrick.
