Licensees in South Australia, Western Australia and the Northern Territory will soon be transitioning to POMS.Australia Post has advised POAAL that, to assist in the transition from LiPOMS to the new system, Licensees in SA, WA and NT will need to perform a self-pay transaction as the last transaction on the last trading day of this month, being Thursday 31 March.According to Australia Post, this will enable the correct calculation of the one-off interim payment which aligns all fees and commissions to the end of the calendar month.If a Licensee does not perform a self-pay transaction as the last transaction on Thursday then there may be a considerable delay in the calculation of the interim payment.
