You’ll feel the difference after the first week.

FAQ

Everything you want to know before booking a demo.

Can I determine my payment terms myself?

Yes! Payment terms in OpusFlow are fully flexible, so you set them exactly the way your business works.

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.

Can we track whether tickets are being resolved on time?

Yes. OpusFlow monitors initial response and resolution timelines against your configured targets and flags tickets that are approaching or past their deadline. Over time, the ticket data also surfaces patterns — recurring hardware issues, high-volume request types, or areas where response times consistently slip — giving your service management team the information they need to improve the process rather than just react to it.

Do I have to use the onboarding services?

It’s not mandatory to use the onboarding, but we strongly recommend it. Implementing an ERP system is a big step for your organization, and the success of it largely depends on how well your team embraces the platform. A structured onboarding makes all the difference.

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 is a CRM for installers different from a standard CRM?

A standard CRM tracks contacts and deals, and that’s about it. CRM software built for installation companies goes further: it links each customer to their projects, installations, and service history. That means your sales team, planners, and technicians all work from the same customer record, without switching between tools.

What is the customer portal?

The customer portal is a branded, self-service environment where your customers can track their installation progress, access documents, view appointment dates, and submit service requests — without needing to call or email your team. It’s available 24/7 and runs directly from OpusFlow, so everything your customer sees is always up to date.
