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 OpenSolar vs OpusFlow comparison.

Run your entire operation in one place and keep teams aligned

OpusFlow acts as the central workspace for your installation business. Sales, project management, purchasing, warehouse control, planning, automations, documentation, and financial processes all live in one platform, giving every team access to the same up-to-date information.

Because everything is connected, teams stay aligned automatically. Updates made by one department are visible to everyone else, reducing miscommunication and ensuring that projects move forward with clarity and confidence.

Create professional quotations in minutes using OpusFlow

OpusFlow allows you to generate accurate, professional quotations in minutes instead of hours. Customisable templates pull in customer data, system details, and pricing automatically, eliminating repetitive manual work.

This speed helps you respond to leads faster and present consistent, high-quality offers every time. Your sales team can focus on closing deals while OpusFlow handles the structure and accuracy of your proposals.

Manage purchasing and stock control with one source of truth

OpusFlow centralises purchasing and inventory management so your team always works from accurate, real-time data. Materials, orders, and stock levels are directly linked to projects, preventing shortages, over-ordering, and last-minute surprises.

With a single source of truth, planning becomes more reliable and coordination between office and field teams improves. Everyone knows what is available, what is needed, and when it will arrive.

Automate your workflows with OpusFlow and reduce manual coordination

OpusFlow automation removes repetitive tasks from daily operations. As projects progress, tasks are created, reminders are sent, and updates are triggered automatically based on predefined workflows.

Customer Testimonials

Making the switch is a big decision. These companies made it, and here’s what changed.

FAQ

Everything you want to know before booking a demo.

Why do I need a document management software?

Good document management gives every department access to the most up-to-date information at all times, so nothing gets lost between business processes.

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.

How does the CRM help with follow-ups and sales conversion?

Every lead in OpusFlow has a clear next action attached to it. Follow-up tasks are tracked automatically, so no prospect goes cold because someone forgot to call back. Combined with the pipeline overview, you always know which deals need attention and when, without relying on memory or manual reminders.

How long does it take to get up and running?

Most teams are operational within a few weeks. OpusFlow is configured around your workflows by our team before go-live and your job types, project stages, and team structure are set up for you. Onboarding is guided, support is included, and you don’t need an IT department to get started.

What is CRM software for installers?

CRM software for installers is a customer management tool built specifically for installation companies. Unlike generic CRM systems, it connects your leads, quotes, projects, and after-sales service in one place, so your sales pipeline and your operations stay in sync from the first contact to the final handover.

Is my data safe?

Yes! OpusFlow takes security seriously. Every environment has its own dedicated database, hosted and managed by AWS (Amazon Web Services), and we use Clerk for authentication, one of the leading platforms for securing cloud applications.

Can we manage subcontractors and external users separately from internal staff?

Yes. OpusFlow lets you create distinct user profiles with separate permission sets for internal team members, subcontractors, and any other user type you need. Subcontractors can be given access to only the specific modules and records relevant to their work, with no visibility into financial data, other clients, or internal processes. Access can be time-limited and revoked immediately when a project ends.
