Actually, if you are looking for a program to keep track of your customer's information, Intuit makes Cutomer Manager, an application that integrates directly into Quicken and/or Quickbooks. It's a lot cheaper than Microsoft Access at $100 compared to the $230 of Access. Or, another option is ACT!, also $230, but the Intuit Customer Manager should work very well, if not better since it is made/published by the same company...
