Trading Parties have ten (10) business days from the invoice due date to make payment before MOSL will commence formally recovering outstanding debts.

To the extent an invoice remains unpaid after ten (10) business days of its due date, details of the non-paying parties and invoice amount will be published on the MOSL website within two (2) business days. MOSL will also formally notify the Panel and Ofwat of the payment failure.
