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 Sollit vs OpusFlow comparison.
OpusFlow functions as a full ERP platform designed specifically for companies delivering renewable energy installations. Core business processes such as sales, project execution, purchasing, finance, documentation, and reporting all operate within one connected system.
This unified setup ensures that data flows smoothly across teams. Everyone works from the same information, enabling clearer collaboration, better planning, and stronger operational control as your business grows.


OpusFlow centralises customer information, communication, and project history into one accessible view. Built-in CRM functionality gives your team full context at every customer interaction, from first enquiry to long-term support.
With clearer insights and organised communication through Customer Portal, your team can respond faster and more consistently. Customers experience a more professional journey, leading to improved satisfaction and long-lasting relationships.
OpusFlow brings purchasing and inventory management into the same system as your projects and finances. Stock levels, orders, and material usage are tracked in real time, ensuring accuracy across the business.
Working from one source of truth helps avoid delays caused by missing materials or over-ordering. Planning becomes more reliable, and coordination between office, warehouse, and field teams improves significantly.


OpusFlow is built to support installation businesses that expand into additional renewable technologies. The platform adapts easily to projects involving heat pumps, battery storage, EV chargers, wind turbines, and future energy solutions.
As your offering evolves, OpusFlow grows with you. You can manage increasing complexity within the same ERP structure, giving you the confidence to scale without losing clarity or control.
OpusFlow automation reduces manual effort by triggering tasks, updates, and reminders automatically as projects move through different stages. Processes run consistently without relying on constant follow-up from your team.
This automation keeps operations efficient and predictable. Your team can focus on delivering quality work and supporting customers, while OpusFlow ensures routine actions are handled reliably in the background.


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.
OpusFlow integrates directly with Mollie to handle SEPA Direct Debit payments. When a customer signs the contract, they authorise a direct debit mandate at the same time. From that point, payments are collected automatically on the billing schedule without any manual chasing, payment links, or follow-up required from your team.
The tools are designed to be used on-site by sales consultants, not engineers. The PV Designer handles string validation and technical checks automatically, flagging errors without requiring the user to understand the underlying rules. The battery and heat pump calculators guide the user through a step-by-step input flow and generate the recommendation from there. Most consultants are comfortable running a full calculation independently within their first few demos.
For every successful referral, when the referral subscribes to OpusFlow for a minimum of 3 licenses and on an anual contract, both you and the referred installer receive €250.
The referred installer receives their award as a discount to their first years subscription, and you will receive the money via bank transfer as outlined in our terms and conditions.
Yes! You can build your own forms from scratch and save them as templates, so every installation type has exactly the right checklist.
No. We care more about the right mindset than sector knowledge. You’ll learn the industry quickly by working with the product and the team every day. What we do look for is curiosity, ownership, and the drive to get things done.
Yes. You can upgrade from monthly to annual at any time. Once your annual contract ends, you’re free to switch back to monthly if you prefer.
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.
