Reasons to choose OpusFlow

Most platforms track your projects. OpusFlow tracks your margins. Built from the ground up for solar and sustainable energy installers, it connects every job, every euro, and every team member in one system.

Below, we break down some of OpusFlow’s key capabilities that make it a powerful all-in-one alternative in the Eturnity vs OpusFlow comparison.

OpusFlow grows with renewable businesses beyond solar installations

OpusFlow is built to support installation businesses as they expand into additional renewable technologies. Whether you’re adding heat pumps, battery storage, or other energy solutions, the platform adapts to your evolving services.

As your business scales, OpusFlow helps you maintain structure and visibility across all projects and technologies. This makes growth more predictable and allows you to take on more work without increasing operational complexity.

Automations | OpusFlow

OpusFlow automates operational tasks across the entire project lifecycle

OpusFlow automation is designed to support every stage of your workflow. As projects move forward, the platform automatically handles task creation, notifications, document updates, and follow-ups without manual intervention.

This reduces administrative workload and ensures that processes are followed consistently. Your team can focus on delivering quality installations while OpusFlow takes care of the routine operational steps in the background.

OpusFlow keeps everyone on your team working from the same information

OpusFlow acts as a shared workspace where every team member sees the same up-to-date project data. Sales, operations, and installation teams stay aligned through real-time task updates, clear responsibilities, and transparent project timelines.

When information is easy to access and always current, handovers become smoother and mistakes are reduced. OpusFlow helps your team collaborate efficiently, even when managing many projects at once.

API integrations | OpusFlow

OpusFlow integrates seamlessly with external systems through its API

OpusFlow provides an Open API that allows your business to connect essential external tools directly to the platform. This makes it easy to synchronise data with accounting systems, analytics tools, or custom software tailored to your internal processes.

By automating data exchange between systems, OpusFlow reduces duplicate work and keeps information consistent. You maintain flexibility in how your tech stack evolves, while OpusFlow remains the operational core of your business.

OpusFlow accelerates project delivery with built-in solar design

OpusFlow includes native solar design tools that allow your team to create PV layouts directly within the system. Design data is automatically linked to customer records, quotes, and project plans.

This tight integration shortens the time from initial design to installation and reduces errors caused by disconnected tools. Projects move forward faster, and your team gains a more efficient, streamlined way of working.

FAQ

Everything you want to know before booking a demo.

What does the leave management module cover?

You can configure leave types such as vacation, sick leave, and personal leave, each with their own rules and accrual settings. Employees submit requests through a calendar view that shows their own balances and any existing approved leave. Managers approve or reject via a dedicated workflow and approved leave is immediately reflected on the planning calendar. The module also surfaces working-hours compliance warnings in hour registrations, so break and shift rules are checked as hours are logged rather than after the fact.

Why do I need a document management software?

Good document management gives every department access to the most up-to-date information at all times, so nothing gets lost between business processes.

Is a ticket linked to the original installation project?

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.

Is there a dashboard for my financial data?

Yes! Within OpusFlow you get a clear overview of your most important financial data, all in one place.

Does OpusFlow have a time registration module?

Yes! All your employees can log their hours directly in OpusFlow via the mobile web app. Time registrations are linked to projects, so you always have a clear picture of project profitability including labor costs.

Which documents can customers view and download in the Customer portal?

Customers can access any document linked to their project, including quotes, invoices, contracts, and completion certificates. Documents are available securely at any time, so a customer who needs to retrieve their invoice six months after installation can do so without contacting your office.

How does the automated billing work?

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.
