Linja — Manufacturing ERP and production control for industry

Linja is a modern, browser-based manufacturing ERP built for metal fabrication, welding shops and small-to-mid-size industrial companies. It unifies project management, time tracking, purchase orders, inventory, e-invoicing and AI-powered document recognition into one easy Finnish-made platform at https://linja.io.

  • Time tracking — mobile timer, weekly overtime (50 % >8 h, 100 % >10 h), approvals and payroll exports.
  • Purchase orders & receiving — supplier registry, traceability and heat-number capture.
  • Inventory — batch tracking, reservations and FIFO consumption against bills of materials.
  • Welding quality — WPS/WPQR/pWPS, welder qualifications, EN 1090 and ISO 3834 compliance documents.
  • AI document recognition — extract data from drawings, invoices and material certificates.
  • E-invoicing — Maventa integration for sending and receiving Finnvoice / Peppol invoices.
