The calculator is designed to be used by sales consultants on-site, not heat pump engineers. The 3D scan does the heavy lifting for room geometry, the input flow guides the consultant through the remaining variables, and the output is generated automatically from there. The plain-language recommendation is specifically written to be read straight to the customer without requiring the consultant to interpret technical data. Most teams are comfortable running a full assessment independently after a single walkthrough of the tool.

When a project reaches the invoicing stage, OpusFlow pulls the line items directly from the project’s Bill of Materials and generates the invoice automatically, with correct quantities, pricing, and totals already populated. For service contracts, you set a billing frequency at the start and the system generates and sends invoices on schedule without anyone triggering it manually. A built-in dry-run mode lets you simulate a billing cycle before it goes live.

Solar yield calculations are based on real localised irradiance data, factoring in the exact orientation, tilt, and shading conditions entered during the design. The ROI model incorporates current energy tariffs, applicable subsidies, and hardware degradation curves to build a 25-year projection. For the Dutch market, additional levers are available including feed-in cost modeling and salderingsregeling phase-out scenarios. The methodology is consistent across every consultant, so the numbers your team presents reflect the same underlying model every time.

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.

You can refer professional solar installers and companies working with renewable energy technologies, such as HVAC, battery storage, and EV charging. The ideal referral is an installer with 10+ employees who manages multiple projects and could benefit from running their operations more efficiently with OpusFlow.

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.

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.
