If you're a self-employed person, you often need to be pitching for new clients at the same time as attempting to complete projects for existing clients. Problem is that time may be against you and you soon realise that an all-important deadline is looming. Worse, you don't ever have time to send or chase outstanding invoices, so do not get paid on time. Many small businesses end up going bust this way - profitable companies are only profitable when they get paid. If their cash flow is affected, they can't pay their creditors.26 Feb 2009
