In my work with clients I have provided original Excel workbooks, usually with macros, and databases in Access for a number of clients. I have also worked with existing spreadsheets and databases, mainly to add some more complex features, to automate operations and make them more user friendly. I have also added security features. Several of my clients use the workbooks and databases on a daily basis for preparing price lists, quotations, proposals, etc. Also some of my clients use my work to evaluate and reorder inventory of various types.
