I use SM to keep track of my consulting business. Most of my business is with large banks where I support either a department, or team. Each of the members can assign me a project. My problem comes in when one of these contacts either moves to another company, or other job within the organization. When I update my contact info in OSX Contacts, the new info appears in the contact info for SM. For auditing purposes I need to generate reports during the course of the year that contain historical as well as current work. So far the only way it seems I can keep my historical reports accurate is to make a completely new entry in OSX Contacts for client contacts who change jobs. That seems cumbersome. Is there a better solution?
How can I keep the client contact info intact when the contact person moves to another job?
