If you are looking for accountancy documents I assume that you don't have any accounts software at present.
Try Sage. Brilliant support and you can pick up a copy from larger office supply companies or order it on the website. The good bits are that you can upgrade to bigger packages as you grow and it is a well used software, there are lots of people trained to use it so as you grow you can hire a clerk to input your data.
Your Profit and Loss account will depend on what headings you are using. If you are still stuck - email me:
nora@arleysangels.co.uk and I will send you a spreadsheet back with a very basic layout.
