Does your product or service generate a positive outcome for your customers?
If you answered with yes, your business generates a profitable Return on investment (ROI). The ROI is a percentage that is calculated by dividing the investment’s net profit by its cost. Example, if you spend $100 on Google Ads that nets you $500 in sales, the ROI is 400%. Pretty sweet.
