I don't know about you, but I rarely write checks anymore - nor do I carry cash - I use plastic; both debit and credit cards. The card I use for any given transaction depends on several factors, not the least of which are the perks related to each card. With my personal debit card, I get cash back that adjusts to the top three spending categories each month. One of my business credit cards gives extra points for grocery and fuel purchases. Being a personal chef, 90% of that card's usage is groceries - Cha-Ching!!
In my business Your Place Gourmet - Personal Chef Service I've decided to accept Visa, Mastercard, Discover, and American Express cards. I find it terribly irritating when the particular store or service provider, from whom I'd like to make a purchase, doesn't accept the card of my choice. I wanted my clients to be able to use their favorite card. I also wanted to offer payment plans and automatic billing to my regularly scheduled clients.
