Hi Mat,
Not sure what sort of venture you have, but have you considered using MS Money?
I use it for my own books and also do book-keeping, payroll and VAT returns for several other small businesses - including a beauty salon, astrologer, builder and decorator, taxi driver, author, etc. The reports facility is quite extensive and gives cashflow info, transaction analysis, bank account balances, etc. I use the reports to submit to various accountants who prepare my customers' accounts and have had positive reports on the info provided. It's dead easy to set up and use after a little thought on the categories and payess have been set up.
