The front office, not the shop floor.
erp4.us is made for the front office of industrial SMEs. It is not a shop-floor MES: no physical stock management, no scheduling or capacity planning, no time tracking, no quality management, no maintenance or after-sales service. If your main need is there, erp4.us is not the right tool — and we prefer to tell you so.
Ready for e-invoicing.
E-invoicing is becoming mandatory: reception for all companies from September 1, 2026, issuing extended to SMEs and micro-enterprises in 2027. erp4.us issues invoices in the Factur-X format and interfaces with a dematerialization platform (PDP).
