Prepayment support enables utilities to offer "Pay As You Go" services allowing customers to manage energy credit through top-up payments. It records financial balances, sends low credit notifications, and automates disconnects and reconnects based on payment rules. Prepayment support can decrease write-offs by 10-15% through increased efficiency, empower customers to avoid debt, and help utilities meet regulatory guidelines for low-income customers. It supports both meter-managed and central-managed prepayment models.
