Monthly billing
Charges for the agreed period are billed together according to the closing date, invoice date and due date stated in the contract.
Corporate customers may use monthly billing or payment in advance under terms agreed by both parties. The contract, quotation or invoice states the method, amount and deadline.

Before business begins, billing details, payment method, closing date and due date are confirmed in writing. An enquiry or application alone does not approve monthly billing.
Charges for the agreed period are billed together according to the closing date, invoice date and due date stated in the contract.
The agreed amount is paid before service by the deadline stated in the contract, quotation or invoice. The service is then arranged against the confirmed terms after payment is matched.
Payment terms do not take effect merely by sending an enquiry. Company details, invoice addressee, closing date, due date and contact are reviewed and confirmed in a contract or other written agreement.
You can enquire with the information currently available, even if regions or volume are not final.
