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 Gaussol vs OpusFlow comparison.
OpusFlow is designed as a single platform that covers the full lifecycle of an installation project. Sales activities, project planning, documentation, communication, and financial processes all live in one connected environment, eliminating the need to switch between multiple tools.
With one system as the backbone of your business, information stays consistent and accessible across teams. This reduces errors, improves collaboration, and gives you clear oversight of everything that’s happening, from first lead to final delivery.


OpusFlow helps you manage customer relationships with clarity and structure throughout the entire journey. All interactions, documents, and project updates are stored centrally, giving your team a complete view of each customer at every stage.
Customers benefit from clear communication through Customer Portal, timely updates, and easy access to information, while your team avoids miscommunication and duplicated work. This structured approach builds trust, improves satisfaction, and supports long-term customer relationships.
OpusFlow is built for installation businesses that want to expand beyond solar. The platform supports a wide range of renewable technologies, including heat pumps, battery storage, EV chargers, wind turbines, and future energy solutions.
As your offering grows, OpusFlow adapts without adding complexity. You can manage different project types, technologies, and teams within the same system, giving you the flexibility to grow your business while maintaining operational control.


OpusFlow automation tools help streamline everyday operations by removing manual steps from your workflow. Tasks, reminders, updates, and follow-ups are triggered automatically as projects progress through different phases.
This automation improves reliability and consistency across projects. Your team spends less time coordinating work and more time delivering results, allowing the business to operate faster without increasing workload.
OpusFlow integrates with over 6,000 external tools, allowing you to connect the platform seamlessly with the systems you already use. From accounting and CRM tools to marketing, analytics, and custom software, data can flow automatically between platforms.
These integrations give you flexibility and future-proof your setup. OpusFlow becomes the central operational hub of your business while remaining open and adaptable to your evolving technology stack.


Making the switch is a big decision. These companies made it, and here’s what changed.
Everything you want to know before booking a demo.
Yes, OpusAI is included in every contract. A usage rate limit applies, but if you need more you can increase your limit at minimal cost.
Tickets can be created through several routes: logged manually by your team after a phone call, parsed directly from an incoming email, or submitted by the customer themselves through the Customer Portal. However a request comes in, it ends up in the same structured queue — so nothing gets handled informally through a personal inbox and nothing falls through the cracks.
Solar yield calculations are based on real localised irradiance data, factoring in the exact orientation, tilt, and shading conditions entered during the design. The ROI model incorporates current energy tariffs, applicable subsidies, and hardware degradation curves to build a 25-year projection. For the Dutch market, additional levers are available including feed-in cost modeling and salderingsregeling phase-out scenarios. The methodology is consistent across every consultant, so the numbers your team presents reflect the same underlying model every time.
OpusFlow accepts scans from iPhone Pro (via LiDAR), Matterport, Polycam, and other scanners that export in OBJ, STL, GLTF, or GLB formats. The scan is processed directly in the browser — no file upload to a server is required, which keeps the process fast and keeps your customer data on-device during the calculation.
When a project reaches the invoicing stage, OpusFlow pulls the line items directly from the project’s Bill of Materials and generates the invoice automatically, with correct quantities, pricing, and totals already populated. For service contracts, you set a billing frequency at the start and the system generates and sends invoices on schedule without anyone triggering it manually. A built-in dry-run mode lets you simulate a billing cycle before it goes live.
Yes. OpusFlow includes a built-in PV designer, energy simulation engine, heatpump and ROI calculator. Your sales consultants can design the system, model a 25-year financial projection, and hand the client a professional proposal all in a single appointment, without waiting for back-office sign-off.
Very. OpusFlow’s Role-Based Access Control lets you define permissions at the individual module, record type, and field level. You can restrict a user to read-only access on financial data while giving them full edit rights on projects, for example. Permissions are assigned via profiles that you can apply to multiple users at once, so updating a role type updates everyone assigned to it in a single action.
