When materials lists are built by hand and yield figures are copied between tools, something eventually gets missed. And that mistake does not show up until the crew is already on-site.
You open satellite images in one tab, calculate yields in another, and manually type out a materials list in a spreadsheet. By the time the proposal is ready, hours have gone by and the customer has already called your competitor.
You build the quote from memory, copy-paste from old projects, or guess which substructure components are needed. Then the installation crew arrives on-site and half the order is wrong.
One colleague uses their own template, another adjusts it, and somehow the customer ends up with something that looks half-finished. A patchy proposal tells a customer everything they need to know about how you run your projects.
Draw the installation directly on a satellite image, and let the system handle the rest.
The moment your design is done, the correct materials are pulled in automatically.
Select your template, make any final adjustments, and send. Every quote looks sharp and on-brand.

OpusFlow connects directly to leading substructure suppliers including ESDEC, Blubase, Van der Valk and Sunbeam, pulling the correct materials list into your quote automatically. If you work with a different provider, you can add articles manually and the ROI calculation stays intact.
OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.
Every installation plan in OpusFlow automatically accounts for shading and installation losses based on the actual roof layout. This means your yield calculations reflect real-world conditions, not best-case assumptions. Your customers get honest, credible numbers.
Drawing a roof in OpusFlow now starts with defining the ridge side, with a live preview updating as you go. This removes one of the most common sources of rework: getting the panel orientation wrong at the start. Whether you work on simple pitched roofs or complex commercial layouts, the designer guides you through each step so the plan is right the first time.

OpusFlow runs a billing engine every night that checks all active contracts and automatically generates invoices for any that are due. There is no manual step required and no risk of a billing run being forgotten because someone was on holiday. The system also includes built-in safeguards that prevent a customer from ever being billed twice for the same period.
OpusFlow is an all-in-one business management platform built specifically for solar, heatpump, battery, charging stations and other sustainable energy installation companies. It connects your sales, operations, planning, warehouse, and finance in one system so your whole team works from the same data, not separate spreadsheets messaging apps or other external apps or software.
Yes. The customer portal displays a visual milestone tracker showing exactly where the project stands, from initial survey through to commissioning. The indicators update in real time as your team progresses the project in OpusFlow, so customers always have an accurate picture without needing to chase your team for an update.
Yes! OpusFlow is an ERP system built specifically for sustainable installers. Beyond the full ERP suite, it includes industry-specific tools like a PV Designer and Battery Calculator. All designed to work together in one platform.
OpusFlow currently integrates with Google Workspace, Microsoft 365, Mollie for payment processing, the Dutch 2BA product catalog, Exact and Peppol for accounting and e-invoicing, and AEAT for the Spanish market. For tools not on this list, the open API allows you to build custom integrations and connect OpusFlow to virtually any platform in your existing stack.
Yes. OpusFlow’s Multi-Entity Finance feature lets you manage multiple companies, labels, or subsidiaries from a single account. Each entity gets its own branding, invoice number sequences, payment terms, and accounting integration. Projects and quotes are automatically linked to the correct entity, so there’s no risk of invoices going out under the wrong logo or routing to the wrong general ledger.
Yes. Every ticket is linked directly to the parent project in OpusFlow, which means the moment a service request comes in, the person handling it has immediate access to the original Bill of Materials, installation photos, engineering models, and the full project history. There is no need to search through archives or ask a colleague — the context is already there.
Yes. The CRM is used by companies installing solar panels, heat pumps, EV charging stations, air conditioning systems, and more. You can tag and filter customers by installation type, which means your pipeline and customer records always reflect the specific products and services your business offers.
Yes. A single automation can span multiple modules — for example, when an installation is marked complete in project management, it can trigger an invoice in finance, create a follow-up task for the sales team, and send a completion notification to the customer portal simultaneously. Workflows aren’t limited to one department, and you can build approval chains that route between teams as part of the same sequence.
No. Automations in OpusFlow are configured through a visual rule builder — you select a trigger, add conditions, and define one or more actions. No code involved. For more complex workflows, pre-configured automation templates give you a proven starting point you can adapt rather than build from scratch. Most teams have their first automations running within an hour of setup.
Yes. Field-captured photos linked to the project are displayed in a gallery within the portal, including installation progress images and final commissioning shots. It’s a straightforward way to keep customers informed and build confidence in the quality of the work being done.
