Reasons to choose OpusFlow

Most platforms track your projects. OpusFlow tracks your margins. Built from the ground up for solar and sustainable energy installers, it connects every job, every euro, and every team member in one system.

Below, we break down some of OpusFlow’s key capabilities that make it a powerful all-in-one alternative in the Solarstream vs OpusFlow comparison.

OpusFlow keeps your entire business in one connected platform

With OpusFlow, all your core processes live in a single system. Sales data, project information, customer communication, purchases & stock, documents, forms, and financials are always connected and up to date.

By working from one source of truth, your team avoids duplicate work and missing information. Collaboration becomes easier, handovers are clearer, and management gains better visibility into what’s happening across the business at any given time.

Automations | OpusFlow

OpusFlow automates your installation workflow end to end

OpusFlow is built to reduce manual work from your daily operations. Automations connect every step of your process, from lead capture and quoting to planning, invoicing, and follow-up. Instead of pushing projects forward by hand, OpusFlow automatically triggers tasks, reminders, and updates as work progresses.

This creates a smoother, more predictable workflow for your entire team. Less time is spent on admin and coordination, and more time goes into selling, installing, and delivering high-quality projects.

OpusFlow includes native solar design built into your workflow

OpusFlow’s integrated solar design functionality allows your team to create PV layouts directly within the platform. Designs are automatically linked to customer data, quotes, and project stages, eliminating the need for disconnected tools.

This integrated approach speeds up quoting, reduces errors, and ensures that design decisions flow smoothly into execution. Your team works faster, projects move forward without friction, and your business gains a competitive edge through efficiency.

OpusFlow scales with your installation business as it grows

OpusFlow is designed for businesses that plan to grow. Whether you’re increasing lead volume, expanding your team, or adding new services, the platform adapts without becoming harder to manage.

You can track performance, identify inefficiencies, and maintain control even as operations become more complex. OpusFlow gives you the structure needed to scale confidently, without sacrificing visibility or operational discipline.

OpusFlow supports a complete and transparent customer journey

OpusFlow helps you manage customer relationships from first contact to post-installation support. The built-in CRM, Customer Portal, and communication tools ensure that every interaction is tracked and easy to follow.

Customers stay informed through automated updates and shared documents, while your team always knows the next step. This level of clarity builds trust, reduces misunderstandings, and delivers a professional experience that reflects the quality of your work.

How long does an onboarding take?

Where a traditional ERP implementation can take months or even years, OpusFlow is designed to get you up and running in just a few weeks. The platform works intuitively, which means less time spent on training and significant cost savings from the start.

What are the integration capabilities?

OpusFlow intergrates with many other software including Zapier or Exact accounting. OpusFlow offers an API solution to connect to any other software to import or export data.

How does OpusFlow help with planning and scheduling?

The planning module replaces whiteboards and group chats with a live drag-and-drop calendar. When a job changes, the whole team is notified instantly via smart automations. Conflict detection prevents double-bookings, and every scheduled job is linked directly to its project record so field teams have everything they need before they arrive on-site.

Can I also fill out forms on my phone/tablet?

Yes! All OpusFlow modules work on any device, so filling out forms on your smartphone or tablet is no problem at all.

What does contract management in OpusFlow actually cover?

OpusFlow lets you create service and maintenance contracts, send them to customers for digital signature, and then automate the entire billing cycle that follows. Once a contract is active, invoices generate and payments are collected on the schedule you define — without anyone on your team needing to trigger it manually. It is designed to turn one-off installation projects into predictable, recurring revenue without adding to your team’s workload.

Can my sales team build quotes and ROI proposals on-site?

Yes. OpusFlow includes a built-in PV designer, energy simulation engine, heatpump and ROI calculator. Your sales consultants can design the system, model a 25-year financial projection, and hand the client a professional proposal all in a single appointment, without waiting for back-office sign-off.
