Designed and developed a multi-tenant cloud-based SaaS platform for real-time enterprise printer fleet monitoring, automated copy tracking, and invoice generation. The system integrates SNMP-based data collection using standard and vendor-specific Printer MIB OIDs to capture accurate page counters, toner levels, device status, and usage metrics across multiple client locations. Built a secure backend architecture for storing historical copy readings, enabling on-demand invoice calculation rather than continuous recalculation, optimizing performance and database efficiency. Key features include: • Real-time printer monitoring dashboard • Historical copy tracking for billing accuracy • Automated invoice calculation based on usage thresholds • Multi-client (multi-tenant) architecture • Secure hosting and server configuration management • Cloud agent integration for remote printer communication • Database optimization for large-scale copy data storage The platform supports enterprise-level scalability and is designed for managed print service (MPS) providers.
