oneS PMSb is an integrated building management software system with built-in e-invoicing tools, helping management units save costs, fully comply with tax regulations, and maintain flexibility and efficiency in operations.
New regulations on electronic invoicing issued by the Tax Authority are placing urgent demands on building, apartment, and urban area management units: invoices must be issued at the right time, in the correct format, with system integration and transparent data. However, investing in separate, bulky software or outsourcing invoicing services often leads to increased operational costs and a lack of system-wide efficiency.
