One of the biggest mistakes most businesses make is focusing all their effort on finding new customers and forgetting about the ones that just bought from them. This is a big mistake because it cost money in the form of advertising and marketing to acquire a new customer.
Your business will make more profits by increasing sales from existing customers because It is up to six times easier and cheaper to sell again to an existing customer than it is to sell to a new potential customer.
Your ideal goal should be to find and keep customers for life. The best investment and ROI is to invest in your current customers and cultivating new business from them than you are trying to chase down new clients. Just a 5% increase in customer retention (stop existing customers leaving) produces a 25% to 100% improvement in profit.
