It is easy to find generic business forms and standard letters online but finding forms specifically relating to the catering business can be more difficult. However, if you can get a hold of specific documentation used in the catering industry that you can adjust for your own use then you will be saving yourself a lot of time in the early days of your business.
Using 'Unbound' Access forms changes the dynamics of how you use and control records via a form. The obvious point is that by default the form loads with no data attached to it which improves the general performance especially if you had quite a busy looking form with many controls. How you create a connection to associate data to your form would normally mean using Access VBA code (with reference to DAO or ADO _ another time!) that allow users to control when to edit, update, delete and save changes to records.
