Can I pay my invoice(s) in installments?
No. Invoices must be paid in full.
Invoices are sent annually, unless you request otherwise. It is possible to be billed half-yearly or quarterly. If you wish to change your payment schedule for next year, you must request this before 15 December of the current year. Once a yearly invoice has been issued, it is not possible to be billed half-yearly or quarterly for that year.
