Unless you're a CFO type then don't do it yourself. One of the best things I ever did was get a bookkeeper. They know the rules, prepare everything for your accountant to sign off and will make you more money in tax savings than they usually cost.

Doing the accounts might seem like a monthly thing, but realistically the amount of stuff you have to learn, understand and keep up with takes your time away from working on your business. If you can afford it, don't do it.
