How it works!

This software package facilitates utility companies toautomatically prepare and submit invoices, thereby helping theircash flow management on one hand. The plant's automation system may be Programmable Logic Controllers (PLC), Programmable Automation Controllers (PAC), Distributed Control Systems (DCS), or Supervisory Control and Data Acquisition Systems (SCADA). The architecture of the system allows aISHa to work with any make of automation system and tariff meter. The system is also designed to accept manual entry of data byauthorized persons.


Pass system process them, so as to perform tariff calculations and generate the desired invoices for the billing period, as laid down in the purchase agreement.
