AI-Powered Waste Management Platform
Reimagining waste management — one invoice at a time. An AI-Powered Invoice Processing Platform setting a new standard for automation, compliance, and efficiency, transforming manual invoice handling into intelligent, automated workflows.
Project Overview
The Vision
At Pristren, we built this platform to solve a clear challenge: manual invoice handling was eating time, drowning teams in paperwork, and leaving room for costly human errors. So, we built a smarter path — powered by intelligence, not repetition. Now live and transforming operations with ≥90% accuracy in automated data extraction using advanced AI models, support for scanned and digital PDFs (even multi-invoice batches), intelligent credit/debit recognition with real-time validation workflows, and GDPR/Swiss DSG-grade compliance. Real results speak for themselves: 70% less manual processing effort, 40% drop in admin overhead, CHF 25,000+ saved in supplier benchmarking, and audit perfection with zero findings. At Pristren, we believe automation isn't about replacing human effort — it's about amplifying it. This platform is more than software; it's a step toward an intelligent, sustainable future for the waste management industry.
Technical Details
A comprehensive web-based platform that revolutionizes waste management invoice processing through advanced AI technology. The solution achieves ≥90% field accuracy in data extraction, processes multiple invoice formats, and provides comprehensive analytics for cost optimization and compliance management. Built with Natif AI for OCR and machine learning processing, the platform handles both scanned and digital PDF invoices up to 200MB, features smart splitting to automatically detect and separate multiple invoices, and includes advanced fingerprinting for duplicate prevention. The system features intelligent credit/debit recognition and real-time validation workflows, with GDPR/Swiss DSG-grade compliance baked in. The intuitive multilingual interface includes a localized German UI, powered by Next.js & TypeScript with React Frontend, MongoDB Backend, and SFTP + API integrations. The system provides automated audit trails ensuring GDPR/Swiss DSG compliance, reducing regulatory risk and improving reporting transparency.
