PSIpenta/ERP is a modular ERP system for medium-sized discrete manufacturers. It covers purchasing, warehouse, production, sales and customer-order handling, with workflow-based process modelling, EDI connections for call-offs and orders, central permissions management and use on mobile devices. Customers license the functions they need, and the interface can be adapted with PSI Click Design. The same vendor offers a separate MES product, PSIpenta/MES, for production control.
PSIpenta/ERP is published by PSI Software SE in Berlin, Germany. According to the company's own investor pages, funds managed by Warburg Pincus LLC secured a majority of PSI shares through a takeover offer settled in July 2026, through the holding company Zest Bidco GmbH, while E.ON keeps a minority stake. A US-managed majority owner is relevant to CLOUD Act questions. The product pages do not state whether the system runs on your own servers or is hosted, or where data is stored, so ask the vendor.
