You will notice a slow loading 'bound' form for larger volumes of data sets which is an overhead that could be easily avoided if adopting the unbound approach. The coding for this type of form is not too exhaustive but does require some basic knowledge which is taught to the more advanced delegate (normally day 4 or 5). Personally, using unbound Access database forms is a more professional and polished approach as it mimics the way a 'true' database system should be operated as well as giving you full control and still maintain data integrity.
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.
