Customer Acquisition is more about acquiring customers that stay lifelong or for a long duration of time. The old model of Marketing-Lead-Sales-Customers tends to dissociate from a customer after the acquisition. Even while bringing in new customers is important, the ones on-board are more important. When you follow the flywheel model of Attract-Engage-Delight and enable the customers to succeed, your customers work on your behalf and act as promoters for your brand bringing in more referrals. So by centring your efforts around your existing customers through the flywheel of Marketing-Sales-Service opens new customer relationships. Your business succeeds when your customers succeed.
