The ERP built for installation companies.
OpusFlow is an ERP for installation companies that fit solar panels, heat pumps, home batteries, EV chargers and HVAC systems. It is built in Deventer in the Netherlands, has been on the market since 2022 and is used in the Netherlands, Belgium, Germany and Spain, in Dutch, French, English, German and Spanish. One platform covers CRM and quotations, project planning and digital field forms. Time registration, purchasing and stock, invoicing and service contracts sit in the same package.
Quotes are built with the PV Designer, the heat pump calculator and the battery calculator, and the bill of materials of a signed quote becomes a purchase order and a stock reservation for that project. Technicians clock their hours and fill in forms with photos and a signature from the mobile app, and the invoice is generated from the project, in milestones if you work that way. OpusFlow has an open API that makes project, customer, invoice and planning data available outside the platform, for reporting and for links with other systems.
