Yes, OpusFlow is a could-based software and can be accessed from anywhere in the world.

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.

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.

OpusFlow integrates directly with Mollie to handle SEPA Direct Debit payments. When a customer signs the contract, they authorise a direct debit mandate at the same time. From that point, payments are collected automatically on the billing schedule without any manual chasing, payment links, or follow-up required from your team.

When a project is confirmed, OpusFlow reserves the required stock against that project automatically, based on the Bill of Materials. The reservation is hard — meaning those items cannot be allocated to another project, eliminating the double-allocation problem that causes install-day shortages. Stock levels across your warehouses, vehicles, and staging locations all update in real time so you always have an accurate picture of what is actually available.

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.

Yes. The customer portal carries your branding, so the experience your customer has is consistent with the rest of your communications. It reinforces your company’s identity rather than surfacing OpusFlow’s.
