When calculating an ROI it’s important to consider what a customer is worth to your business, and then ask yourself how much revenue would increase if each customer came in one more time per year? One more time per month? One more time per week? CityGro offers the ability to constantly communicate with past customers so they don’t forget about you. Our average business adds 2,000 people to their database each year. This amounts to a $20,000 increase in revenue for every additional $10 dollars spent!
