Do you recognise this situation? You're flat out dealing with customers, getting the job done on time, when you get a call from one of your suppliers. You're 45 days overdue with their invoice and they're refusing to supply the goods you need to complete your jobs or sell to customers until you pay the outstanding amount. You tell the supplier “as soon as I can get my customers to pay – I'll pay you” and with that you either head over to your accounts staff and ask them what the holdup is, or you jump on the phone yourself and ring a handful of customers who have large outstanding accounts.
