I am not a developer hence please guide on the steps or material or videos to do the below.

I have created a form to collect products we sell this just captures basic information of the products like Name (single Line Field), description (Multi line Field) and Part number(Single line field).

i would like to generate a sales order, for the same i would like to call this data from the products form and add quantity, rate and amount and do the calculations. etc.

I would then based on the SO generated would like to add a Purchase order and Invoice and based on this data would like to make a delivery note.
