THE PROBLEM

Running a growing installation business is complex enough.

Your software shouldn't make it harder.

Most installation companies are managing projects, quotes, teams, and finances across five different tools, and none of them talk to each other. Your sales team works from one system, planning from another, and finance from a spreadsheet no one fully trusts. The result is wasted hours, avoidable errors, and a business that’s harder to run than it needs to be.

Your data lives in too many places

Quotes in one system, planning in a spreadsheet, invoices in another. Nothing talks to each other. Your team wastes hours re-entering the same data, and errors slip through every handover.

Admin is eating your team's time

Every quote, invoice, and purchase order is built from scratch. Chasing approvals, updating statuses, sending reminders – it is all manual. And as your business grows, so does the workload.

You only find out when something goes wrong

Project margins, team capacity, stock levels – the picture only becomes clear at month-end. By the time the report lands, the decisions have already been made.

FAQ

Everything you want to know before booking a demo.

What is the customer portal?

The customer portal is a branded, self-service environment where your customers can track their installation progress, access documents, view appointment dates, and submit service requests — without needing to call or email your team. It’s available 24/7 and runs directly from OpusFlow, so everything your customer sees is always up to date.

Do I need technical knowledge to build automations?

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.

What security standards does OpusFlow support?

OpusFlow supports Single Sign-On (SSO) and Multi-Factor Authentication (MFA) for all users. Every login event and critical data action is recorded in an immutable audit log that cannot be edited or deleted. Role-based access control ensures users only interact with the data and modules relevant to their role. For businesses operating across multiple entities, each company can be managed with independent access configurations under the same overarching account.

Is my data safe?

Yes! OpusFlow takes security seriously. Every environment has its own dedicated database, hosted and managed by AWS (Amazon Web Services), and we use Clerk for authentication, one of the leading platforms for securing cloud applications.

Can I also fill out forms on my phone/tablet?

Yes! All OpusFlow modules work on any device, so filling out forms on your smartphone or tablet is no problem at all.

What type of companies can use OpusFlow?

OpusFlow is built for sustainable installers: think solar, heat pumps, air conditioning, climate control, and wind farms. General installation companies are equally at home on the platform. Thanks to its modular setup, you simply switch off what you don’t need and focus on what matters to your business.

What is the process for managing user permissions and roles?

OpusFlow gives you full control over who sees what. With the User Management module you can restrict access per employee, down to individual modules and actions, so your data stays exactly where it belongs.

Are there any industry-specific modules?

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.

Can the software be accessed remotely (cloud)?

Yes, OpusFlow is a could-based software and can be accessed from anywhere in the world.

What kind of customer support and training is provided?

Our onboarding process includes interactive video tutorials you can revisit at your own pace, plus personal support from our consultancy team whenever you need it. After onboarding, you’ll have access to a comprehensive knowledge base and can always reach our support team by phone or email. And whenever major updates roll out, we keep you informed through newsletters and updated tutorials.

What are the integration capabilities?

OpusFlow intergrates with many other software including Zapier or Exact accounting. OpusFlow offers an API solution to connect to any other software to import or export data.

Do you have a mobile version?

Yes! Our Mobile Web App allows you to access the OpusFlow software from anywhere in the world.

Can I transfer data from my current software package to OpusFlow?

Yes, data migration is part of our onboarding process. Our import module lets us transfer almost any database from your current software, and your account manager will guide you through every step. Book a free demo to get started.

Does OpusFlow’s CRM work for different types of installation companies?

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.

Still have questions?

Our team knows the product inside out. Ask us anything — no sales pressure, no scripts.
