Just wanting to know if anyone has any recommendations as far as a basic billing system goes. Is there a good computer program to use? A decent proportion of my clietele are elderly and they tend to talk my ear off when it is time to collect the money. I would be able to get more done in a day if contact were kept to a minumum and I could just mail my clients their bill. Do you recommend billing every two weeks, monthly, or what? Thanks for the feedback!
