Why opusflow

Benefits for your company

OpusFlow’s ROI Calculations module gives every proposal a financial foundation clients can trust. Payback periods, savings forecasts, and energy breakdowns are calculated automatically and included in every quote.

Instant ROI clarity
Show payback periods, savings, and returns the moment a quote is built.
Close deals with real numbers
Use data-backed proposals to build trust and handle objections with confidence.
Tailored to every situation
Set local energy prices, monthly usage, subsidies, and battery scenarios per quote.
Proof your clients can see
Graphs, energy diagrams, and KPI visuals are included in every PDF proposal.

SOUND FAMILIAR?

Your numbers are guessed. Your clients know it.

Installation companies don’t lose deals because their work is bad. They lose them because the financial story they tell is vague, inconsistent, and built on assumptions. When a client asks “but what will I actually save?” and the answer takes three days or comes from a spreadsheet nobody fully trusts, the deal stalls. OpusFlow changes that.

Your solutions

Every quote is built from scratch. Every time.

No templates, no saved inputs, no starting point. Each new ROI calculation means digging up energy prices, subsidy figures, and system specs all over again. The time adds up fast, and so do the inconsistencies.

Someone built a calculator two years ago. It gets copied, tweaked, and passed around until nobody is sure which version is current or whether the formula still works. Clients are getting different numbers depending on who they spoke to.

Switching between a solar calculator, a separate heat pump spreadsheet, and your quoting software to produce one proposal is slow and error-prone. Your team wastes time and clients wait longer than they should.

Start smart. Finish fast.

Reusable templates and pre-configured inputs mean your team builds accurate quotes in minutes.

One version. Updated.

All ROI calculations live inside your quoting workflow, updated centrally.

Both covered. One place.

Solar and heat pump ROI are calculated within the same module.

Monthly energy breakdown

Instead of a single annual estimate, you can split energy consumption per month to reflect seasonal variation. This produces a month-by-month savings prediction that matches how clients actually experience their energy bill. You can set a global energy price or override it per quote for maximum accuracy. The result is a projection clients can follow and verify themselves.

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.

Solar and heat pump ROI in one place

OpusFlow calculates ROI for both solar panel and heat pump installations from the same module. Sales teams working across both product types don’t need separate tools or different workflows. Each installation type uses relevant inputs, so a heat pump quote reflects heating efficiency and energy savings rather than solar generation.

“The ability to adapt our own formats and processes without depending on consultants gives us the freedom to grow and develop as a company.”

Location-specific pricing and subsidies

Every quote can be configured with local energy rates and applicable subsidies rather than averaged figures. The calculation adjusts for panel type, inverter specifications, shading loss, and system efficiency.

FAQ

Everything you want to know before booking a demo.

Do my consultants need technical training to use the calculation tools?

The tools are designed to be used on-site by sales consultants, not engineers. The PV Designer handles string validation and technical checks automatically, flagging errors without requiring the user to understand the underlying rules. The battery and heat pump calculators guide the user through a step-by-step input flow and generate the recommendation from there. Most consultants are comfortable running a full calculation independently within their first few demos.

Is the heat loss calculation certified to a recognised standard?

Yes. The calculation follows the DIN EN 12831-1:2017 methodology, which is the recognised European standard for determining building heating load. It covers per-room heat loss including U-values, thermal bridges, ventilation, airtightness, and surface adjacency. The output is a DIN-compliant PDF report that includes a per-room breakdown, total heat demand, and the final hardware recommendation — suitable for use as supporting documentation with the customer or for your own internal records.

Which 3D scanning tools does OpusFlow work with?

OpusFlow accepts scans from iPhone Pro (via LiDAR), Matterport, Polycam, and other scanners that export in OBJ, STL, GLTF, or GLB formats. The scan is processed directly in the browser — no file upload to a server is required, which keeps the process fast and keeps your customer data on-device during the calculation.

Can the heat pump calculation be combined with a solar or battery quote in the same proposal?

Yes. The heat pump calculator sits inside the same quotation flow as the PV Designer and battery calculator, so your consultant can cover solar design, battery sizing, and heat pump assessment in a single appointment and present a combined proposal with a full renewable energy picture — including a joint ROI calculation — in one branded PDF. No switching between tools, no separate follow-up visits.

How accurate are the solar yield and ROI projections?

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.

Can all three calculations — solar, battery, and heat pump — be combined into a single quote?

Yes. The solar design, battery recommendation, and heat pump sizing all feed into the same quotation flow within OpusFlow. The combined ROI can be presented as a single financial picture covering the full renewable energy installation, and the full output exports into one branded PDF proposal. Your consultant can cover all three in a single appointment and send a complete, itemised quote before leaving the customer’s home.

What happens after the appointment — does OpusFlow handle the follow-up too?

Yes. Once the design and calculation are complete, OpusFlow’s automation engine can send a templated follow-up email the moment the quote goes out. OpusAI goes further: instruct it in plain language to draft a personalised proposal email, create the CRM contact record, and summarise the system spec from your notes — all without manual data entry. The calculation work closes the deal on-site. OpusFlow handles everything that comes after it.

Does the consultant need technical training to run the heat loss calculation?

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.
