The features that matter most to your business, compared side by side.
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 Wattwin vs OpusFlow comparison.
OpusFlow gives every team a shared, real-time view of projects, tasks, and timelines. Sales, operations, installers, and back-office staff all work from the same data, ensuring that everyone knows what is happening and what comes next.
This alignment reduces delays and miscommunication across the business. When updates are visible instantly and responsibilities are clear, handovers become smoother and teams can work together more efficiently.
OpusFlow brings core business operations into a single ERP-style platform built specifically for installation companies. Project management, purchasing, invoicing, documentation, reporting, and internal coordination are all connected within one system.
By replacing fragmented tools with one central platform, OpusFlow improves visibility and control. Your business gains a clear operational structure that supports day-to-day execution as well as long-term planning.
OpusFlow helps you deliver a consistent and transparent experience to your customers. All communication, documents, and project updates are stored centrally in a Customer Portal and a dedicated CRM module, giving your team full context at every interaction.
Customers benefit from clearer updates and faster responses, while your team avoids duplicated work and missing information. This structured approach builds trust and supports stronger, long-term customer relationships.
OpusFlow integrates with a wide range of external tools, allowing your business to connect accounting software, marketing platforms, reporting systems, and other services. Data flows automatically between systems, reducing manual input.
The 6000+ integrations make OpusFlow flexible and easy to adapt. You can keep the tools that work best for your business while using OpusFlow as the central hub that ties everything together.
OpusFlow automation connects your processes across sales, project management, purchasing, installation, and aftercare. As a project moves from one stage to the next, actions are triggered automatically based on rules you define. Tasks are assigned, reminders are sent, documents are generated, and internal updates happen without manual coordination.
This structured automation ensures that every project follows the same reliable workflow, even when your team is busy or scaling fast. Nothing gets missed, handovers are clearer, and responsibilities are always visible. The result is a smoother operation that runs efficiently as your business grows.
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. The solar design, battery recommendation, and heat pump sizing all feed into the same quotation flow within OpusFlow. The combined ROI can be presented as a single financial picture covering the full renewable energy installation, and the full output exports into one branded PDF proposal. Your consultant can cover all three in a single appointment and send a complete, itemised quote before leaving the customer’s home.
Yes. The heat pump calculator sits inside the same quotation flow as the PV Designer and battery calculator, so your consultant can cover solar design, battery sizing, and heat pump assessment in a single appointment and present a combined proposal with a full renewable energy picture — including a joint ROI calculation — in one branded PDF. No switching between tools, no separate follow-up visits.
There is no limit to the number of users you can invite to OpusFlow. Each user is billed at the agreed monthly or yearly subscription fee.
Yes. OpusFlow connects with Google Workspace and Microsoft 365 for calendar and email, external accounting packages via API export, wholesale product catalogues via 2BA, and payment processing via Mollie for automated SEPA billing. It also connects to Zapier for endless possibilities.

Both options are available. OpusFlow ships with pre-configured automation templates built around common installation business workflows, which you can deploy immediately and adjust to fit your process. You can also build entirely custom automations from scratch using the rule builder, with full control over triggers, conditions, and chained actions. Most teams start with a template and modify it once they’ve seen how it works in practice.
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. Once the design and calculation are complete, OpusFlow’s automation engine can send a templated follow-up email the moment the quote goes out. OpusAI goes further: instruct it in plain language to draft a personalised proposal email, create the CRM contact record, and summarise the system spec from your notes — all without manual data entry. The calculation work closes the deal on-site. OpusFlow handles everything that comes after it.
