The best way of getting paid if the customer is a limited company is a winding-up petition. Surprisingly, a petition can be issued for any debt over £750 providing it's not contested on any genuine grounds. I've issued dozens over the years, and they are by far the most effective method of getting payment. The County Court system is utterly useless these days. Any half-intelligent or competently advised debtor can easily spin out County Court proceedings for months, and if the debt's less than £10,000 it's classed as a small claim, so you can't normally recover any significant legal costs. Consequently, if you employ a lawyer you can end up out of pocket even if you ultimately get judgment. And even when you do get judgment the court won't do anything of their own volition to help you get paid. You then have to pay even more court fees to enforce the judgment. A winding up petition, on the other hand, is not accompanied by any `how to avoid paying this debt' rubbish, such as the County Court send out. It can be advertised in the London Gazette within a couple of weeks of it being served on the debtor, which means their bank accounts are frozen the same day. Believe me, that does grab their attention! Yes, it's relatively expensive to issue one, but assuming the company actually has the money you'll get it back as well as the payment, and if you've employed a decent lawyer to deal with it you should also be able to get your legal fees paid as well.
