SOUND FAMILIAR?

Your tools don't talk to each other

Most installation businesses aren’t struggling because of bad work on the roof. They’re struggling because their CRM, accounting software, planning tool, and lead platform all live in separate worlds. Data gets copied by hand, mistakes creep in, and your team wastes hours every week on admin that should never exist.

Your solutions

You're copy-pasting data between systems all day.

A lead comes in from your website. You copy it into your CRM. Then into your project tool. Then into your accounting software. By the end of the week, you’ve manually moved the same information five times and introduced errors each time.

Your ads and contact forms are generating interest, but without a direct connection to your workflow, leads sit in a form submission inbox until someone checks it. By then, the customer has already called someone else.

Invoices created in your tools never make it to your accounting software automatically. Someone exports a file, emails it across, and imports it manually. It happens once a week if you’re lucky, which means your financial overview is always a few days behind reality.

One entry. Everywhere.

Data entered once flows automatically to every connected tool. Stop copying and start working.

New lead. Instant action.

Every incoming lead triggers an automatic project or ticket in your system the moment it arrives.

Finance synced. Updated.

Invoice and payment data moves between systems in real time.

Open API with no call limits

OpusFlow’s open API gives your team unrestricted access to project, client, invoice, and planning data across any platform. Whether you are designing installation plan for solar panels, syncing leads from Google Ads, pushing data to a BI tool, the API handles it without throttling your operations.

Works with the tools your business already runs on

OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.

Data migration

Switching to a new platform is a lot less daunting when you know your data isn’t going to get stuck. With OpusFlow’s built-in CSV importer, you can bring in contacts, projects, and other key data from practically any system you’re moving away from. On the other side, the open API lets you send data out to the tools you already rely on, whether that’s your accounting package, your emails in Google, Zapier or another platform entirely. And if you’d rather not handle the migration yourself, the onboarding team takes care of it for you.

One integration. Hours saved every week.

OpusFlow customers didn't just clean up their tech stack, they changed how their whole operation runs. Read what they found on the other side.

FAQ

Everything you want to know before booking a demo.

Which tools does OpusFlow integrate with natively?

OpusFlow currently integrates with Google Workspace, Microsoft 365, Mollie for payment processing, the Dutch 2BA product catalog, Exact and Peppol for accounting and e-invoicing, and AEAT for the Spanish market. For tools not on this list, the open API allows you to build custom integrations and connect OpusFlow to virtually any platform in your existing stack.

What’s the difference between the automation engine and OpusAgent?

The automation engine runs predefined rule-based workflows in the background — you set the trigger and the actions once, and they fire automatically whenever the conditions are met. OpusAgent is the AI layer that lets you give instructions in plain language and get results on demand. They work well together: automations handle the predictable, recurring work, and OpusAgent handles the ad-hoc requests that would otherwise need manual effort.

Can we import products from supplier catalogs directly into OpusFlow?

Yes, through two routes. The 2BA integration gives you access to over a million supplier products — search, compare pricing, and link results directly to your stock articles, with a bulk sync option to keep pricing up to date across all articles from a given supplier. The ENF integration covers solar panels, batteries, and inverters specifically, auto-populating product specifications on import so you can add new hardware to your catalogue and set your own pricing without any manual spec entry.

How does the migration from our current system work?

OpusFlow is built on an open API, which gives your team or ours a structured way to bring existing data across from your current platform. The onboarding process is guided by the OpusFlow team directly, without the need for expensive third-party consultancy. Because the platform is purpose-built for installation businesses, the setup process is shaped around how your business already works rather than requiring months of configuration to get there. The best starting point is a demo conversation where we can map your current setup to what OpusFlow covers.
