The fastest way to revenue growth is not finding new business, but rather by upselling to your existing customer base!
One study shows that a company can increase its annual sales/revenues up to 30% by simply selling to its existing customers. According to Marketing Metrics, the probability of converting (selling) an EXISTING customer is 60% to 70% while the probability of converting a NEW prospect, on the other hand, is only 5% to 20%.
