OpusFlow is an ERP platform built for installation companies, including solar, heat pump, home battery, EV charging, air conditioning, HVAC, wind farm maintenance and general installation businesses. It brings CRM, quoting, planning, project management, purchasing, invoicing and automation into one system with one login.
The vendor positions it as a replacement for the mix of spreadsheets, separate planning tools and quoting software that many installers run on. It is made by ProfitFlow BV in Deventer, the Netherlands, and the company says more than 3,000 installers use it.
Work moves through connected modules. A lead enters the CRM, a quote is built and sent from the platform, and the accepted job becomes a project in a visual pipeline. Planners schedule crews with drag-and-drop planning, and field staff complete digital forms with photos and signatures on site.
Invoices, timesheets and purchase orders are generated from project data, so details are not re-entered between systems. OpusAI sits across the platform with context of the account. Users ask questions in plain language, request reports, or instruct it to reschedule jobs, assign staff or send emails.
Sales tools include CRM, lead management, quotations and a customer portal where clients see project status, documents and invoices. Operations tools cover planning, purchasing and stock across locations, field data forms, tickets and chats, hour registrations and time off, plus contract management for service contracts.
The calculation tools set it apart from general ERPs: a PV designer, a heat pump calculator using room-by-room heat loss to DIN EN 12831, a battery calculator and ROI projections over 25 years. Automations, workflow management, dashboards with a Power BI link and role-based access complete the set.
