My advice would be to invest in a basic copy of Sage Instant Accounts and use that. It may be a bit overkill for a very small business, but I've always used it from starting out and it's worth its weight in gold now my business is very busy and I'm dealing with lots of customers and suppliers. I can keep on top of my all my accounts in about half an hour a day, if I didn't use it I'd probably have to employ someone to do the accounts. It also helps keep in with suppliers because its easy to see when invoices are due for payment. You can move you data across into the bigger versions very easily as your business gets bigger.
