Supplements and populating "reports"

I am a nutritional therapist and order supplements for my clients. When I recommend supplements I need to produce 4 different “reports” from one set of data. If I order supplement A, supplement B and supplement C I need to enter: the supplement, cost, quantity, code, total cost, when they should take it, how many they should take and some of this information to needs to populate 4 “reports” and I only want to have to enter this information once as this is very time consuming. The “reports” are

1) an invoice for the client
2) an order – either email or fax – for the supplement company
3) fridge report for the client – this tells them when to take ther supps and how many
4) a supplement history for each client – so I can see at a glance what they have been taking over time

I would be so 😀 if this is possible – it must be [-o<
Thanks
