SOUND FAMILIAR?

Quoting is costing you more than you think

Most installation companies don’t lose deals because of the work. They lose them because quotes take too long, follow-ups get forgotten, and customer info is scattered across inboxes and spreadsheets. OpusFlow fixes that.

Your solutions

Quote built. Deal sent. Before you leave.

Leads in your inbox, quotes in a spreadsheet, project notes in someone’s head. By the time you piece it all together, the moment has passed and the deal has gone cold.

Every day you spend waiting for a quote to be built is a day your prospect is talking to someone else. Speed is where deals are won and lost in this market.

Without a system tracking what needs doing and when, leads go cold and service calls get missed. Not from lack of effort, but because no one can keep up manually.

Quote built before you leave the driveway

Every project, email, and document linked to one profile. Pick up the phone knowing everything before you say hello.

Every spec checked. Every quote bulletproof.

Build a quote, run the ROI, and send a professional proposal in the same appointment.

One click to sign. Zero reasons to wait.

Every lead tracked from first contact to signed contract, with automatic follow-up tasks so the next step always happens.

Your quote doesn't go silent after you hit send

Most quotes disappear into a black hole the moment you hit send. OpusFlow shows you exactly when your prospect opened their quote and how many times they’ve come back to it. So instead of awkward “just checking in” calls, your reps reach out at precisely the right moment when interest is already there. Less guessing, more closing.

FAQ

Everything you want to know before booking a demo.

Do you charge per quote or per project?

No. One subscription covers everything, no matter how much you use it. You should never be penalised for growing your business.

Can I add my own price lists?

Yes! You can add price lists, product prices and discounts directly in OpusFlow, so your team always works with the right figures when building a quote.

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.

What can a customer actually see in the portal?

Customers have access to real-time project milestone tracking, all commercial documents linked to their project, scheduled appointment and survey dates, photo galleries from the installation, and a communication thread with your team. Everything relevant to their project is in one place, presented clearly without exposing any of your internal data or other customers’ records.

Can I add time estimates to my calculation?

Yes! You can create and save your own time standards in OpusFlow and apply them directly to any calculation.

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.

How can I calculate a project within OpusFlow?

OpusFlow has a dedicated quotation and calculation module that gives every project a solid financial foundation. For PV installations, the built-in PV Designer lets you calculate directly from your installation plan, and the Battery Calculator helps you size and financially justify a battery storage system on the spot.

Does OpusFlow replace our external accounting software?

No, and it’s not designed to. OpusFlow handles everything up to the point of invoicing — project data, BOMs, hours, contracts, and administration — and then exports clean, structured financial data directly to your existing accounting package via API. Your accountant keeps working in the tool they already know. You just stop spending hours preparing the data they need.
