I need to be able to track the Service Units purchased by my Clients each month. Information for a Service Unit is supplied by a vendor. The service is preformed by a Service Provider, at a variable cost. So I need to track: 1. clients 2. service units 3. vendors 4. Service suppliers 5. Cost of service (by supplier) 6. Date service was performed I need to be able to get 1 report that tells me All the services that a Client has received in order of Date In another report (or view) I need to be able to see that: Service A was purchased by Client C in Sept 2010. I've never done this before, so I'm not sure if I described the project correctly.
