Hi Danielle,
Yes, we do that here at Wollongong. Generally once they get to an unacceptable level of fees outstanding, normally around 90 days overdue (depending of value being tipped each month). We notify our waste team and the weighbridge (and the debtor) that credit has been suspended and they have to pay cash each time they go.
Once the overdue amount is paid, we then re-instate the credit facility.
We also have it written in to our Sundry debtor policy, that if an organisation intends to or tips more than 5K per month, we have them complete a directors guarantee for any pty ltd organisations.
Hope this helps.
Regards,
Dallas
