WHERE EV CHARGING INSTALLERS LOSE MARGIN

Three places every job gets harder than it needs to be

It’s rarely one big failure. It’s the quote that took three days instead of one, the charger that wasn’t in stock on install day, the commercial rollout that nobody could keep track of across sites. These are the three places OpusFlow closes the gap for EV charging installers.

Sound familiar?

Your sales process costs you deals

Your consultant visits the site, goes back to the office to configure the installation 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. Residential customers move on fast. Commercial customers move on faster.

Ten chargers across three locations, different crews on different days, materials ordered in batches. Nobody has the full picture. Updates happen by phone. Something always falls through and you find out too late to fix it without cost.

The install goes well, but the invoice goes out days late with missing line items. Hour registrations aren’t submitted on time. On a large commercial rollout, these small gaps add up fast and by the time the job is closed, the margin is already gone.

Quoted on-site. Deal closed.

OpusFlow gives your consultant everything they need in one screen. Configure the installation, build the material list, 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.

Every site. Every crew. One overview.

OpusFlow links every installation to its parent project, with real-time status updates, crew assignments, and material tracking across every location. Your planner sees the full picture at a glance, and your field crew gets push notifications the moment anything changes.

Clean records in. Accurate invoices out.

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, on every job, across every site.

From single install to full commercial rollout

Managing a single EV charger installation is straightforward. Managing a rollout across a business park with multiple crews, phased delivery, and batch material orders is a different challenge entirely. OpusFlow gives planners a drag-and-drop scheduling calendar with conflict detection and real-time push notifications to field crews the moment anything changes. Every installation links to its parent project, so your team always knows what’s happening where, and your back office always has the data it needs to invoice accurately and on time.

Planning OpusFlow

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.

Your AI co-worker for EV charging operations

OpusAI agent is built directly into OpusFlow. Tell it what you need in plain language, show me all open EV jobs across our commercial sites this week, create a service ticket for the charger fault at location Eindhoven, build a report on install costs per site for the Breda rollout, and it handles the rest. No navigation, no clicking through menus. This native data assistant has full context of every project, schedule, quote, and invoice in your account, so its outputs are specific to your business, not generic suggestions.

One platform. Every part of the business covered.

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.

FAQ

Everything you want to know before booking a demo.

How does the automated billing work?

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.

Is a ticket linked to the original installation project?

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.

Can customers see photos from their installation in the Customer Portal?

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.

Can customers track where their installation is in the process?

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.

We run more than one company under the same group. Can OpusFlow handle that?

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.

Can automations work across different departments and modules?

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.

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.

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.

Can I make a calculation based on my installation plan?

Yes! With the PV Designer you can design both private and commercial roofs and generate a full calculation and Bill of Materials directly from your installation plan.

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.

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.

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.

What is OpusFlow and who is it built for?

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.
