You should have a field for couples. If you have a young couple you may wantn to place an area that indicates this so you kow what products to offer s they expand their family. A birthday field is a great customer service tool that way you can send birthday and holiday cards to your clientes. Lastly, I think you should add a profession field. Learn and keep track of where your clients work that way you hace a reference when you go into business to offer products to their employees AND offer group rate to that customer.
