It’s rarely one big failure. It’s the quote that took two days instead of one, the unit that wasn’t in stock on install day, the invoice that went out a week late with a missing line item. These are the three places OpusFlow closes the gap for air conditioning installers.
Your consultant visits the site, goes back to the office to size the system, work out the savings, and put together a proposal. By the time it lands in the customer’s inbox, they have two other quotes and the moment has passed.
Nobody checked stock before the job was confirmed. The unit is reserved on paper but already allocated to another job. Your installer arrives and the job has to be rescheduled. The customer isn’t happy. Neither is your margin.
The install goes well, but the invoice goes out three days late with a missing line item. Hour registrations aren’t submitted until the end of the month. By then, the numbers don’t add up and nobody knows why.
OpusFlow gives your consultant everything they need in one screen. Size the system, model the savings, and send a branded, itemised proposal before leaving the appointment. Every quote links directly to the project record, the CRM contact, and the material list, so nothing gets lost between the visit and the install.
OpusFlow reserves materials the moment a contract is signed. Real-time stock levels across warehouses and vehicles mean you always know what’s available. Automatic reorder alerts make sure you’re never caught short on the next job either.
OpusFlow automates the parts that shouldn’t need human effort. Invoices inherit line items directly from finalised material lists. Hour registrations feed straight into project cost reports, so you always know where your margin is going.

AC deals are time-sensitive. The consultant who leaves with a signed proposal wins. OpusFlow gives your sales team everything in one screen: size the system, model the savings, and generate a branded, itemised proposal before the appointment is over. Every quote links directly to the project record, the CRM contact, and the material list, so nothing gets lost between the visit and the install.
OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.
Getting an AC job planned, staffed, and executed without friction is harder than it sounds when you’re running multiple installs at once. OpusFlow gives planners a drag-and-drop scheduling calendar with conflict detection and real-time push notifications to field crews the moment anything changes. On-site, technicians work from digital forms with conditional logic, photo capture, and on-screen signatures that sync to the project record instantly. Hours are logged per task from the mobile app, and that data feeds directly into project cost reporting, so you always know where your margin is going.
OpusAI data assistant is built directly into OpusFlow. Tell it what you need in plain language, show me all open AC jobs planned for next week, create a service ticket for customer Bakker, build a report on install costs by technician, and it handles the rest. No navigation, no clicking through menus. OpusAgent has full context of every project, schedule, quote, and invoice in your account, so its outputs are specific to your business, not generic suggestions.
OpusFlow is not a quoting tool with a few extras bolted on. It is a full business platform built specifically for sustainable installation companies — with 25+ modules covering everything from your first customer contact to your final invoice. Here is what is included.
Everything you want to know before booking a demo.
OpusFlow runs a billing engine every night that checks all active contracts and automatically generates invoices for any that are due. There is no manual step required and no risk of a billing run being forgotten because someone was on holiday. The system also includes built-in safeguards that prevent a customer from ever being billed twice for the same period.
Yes. Every ticket is linked directly to the parent project in OpusFlow, which means the moment a service request comes in, the person handling it has immediate access to the original Bill of Materials, installation photos, engineering models, and the full project history. There is no need to search through archives or ask a colleague — the context is already there.
Yes. Field-captured photos linked to the project are displayed in a gallery within the portal, including installation progress images and final commissioning shots. It’s a straightforward way to keep customers informed and build confidence in the quality of the work being done.
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. OpusFlow’s Multi-Entity Finance feature lets you manage multiple companies, labels, or subsidiaries from a single account. Each entity gets its own branding, invoice number sequences, payment terms, and accounting integration. Projects and quotes are automatically linked to the correct entity, so there’s no risk of invoices going out under the wrong logo or routing to the wrong general ledger.
Yes. A single automation can span multiple modules — for example, when an installation is marked complete in project management, it can trigger an invoice in finance, create a follow-up task for the sales team, and send a completion notification to the customer portal simultaneously. Workflows aren’t limited to one department, and you can build approval chains that route between teams as part of the same sequence.
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.
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.
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.
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.
OpusFlow is an all-in-one business management platform built specifically for solar, heatpump, battery, charging stations and other sustainable energy installation companies. It connects your sales, operations, planning, warehouse, and finance in one system so your whole team works from the same data, not separate spreadsheets messaging apps or other external apps or software.
