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 Syntess vs OpusFlow comparison.

OpusFlow delivers a cloud-based all-in-one ERP for installation businesses

OpusFlow is a cloud-based ERP platform that brings all core operations into one system. Sales, project management, quotations, solar design, purchasing, inventory, invoicing, and documentation are all connected and accessible from anywhere.

By running your business in the cloud, OpusFlow gives your team flexibility without losing control. Everyone works from the same real-time data, making collaboration easier and keeping operations transparent as your business grows.

Automations | OpusFlow

Automate your workflows with OpusFlow and keep projects moving

OpusFlow automation connects your entire workflow across sales, planning, delivery, and aftercare. As a project changes status, the platform automatically triggers the right actions: tasks are assigned, reminders are sent, documents are created, and internal updates happen without manual follow-up.

This structured automation ensures that every project follows the same reliable process, even when your team is busy or scaling fast. Nothing gets overlooked, handovers are clearer, and responsibilities are always visible. By removing repetitive coordination, OpusFlow helps your business run faster and more consistently with less operational effort.

Create accurate solar designs inside OpusFlow with a native PV designer

OpusFlow’s native PV designer allows your team to create solar layouts directly within the same platform used for quoting, planning, and execution. Design data is automatically connected to customer records, system components, and pricing logic, ensuring consistency from the first proposal onward.

By keeping solar design embedded in your operational workflow, OpusFlow reduces errors caused by disconnected tools and manual data transfer. Your team can design, quote, and prepare installations more efficiently, shortening lead times and improving overall project accuracy.

With such calculators your team can plan and price complex systems accurately. As your services expand, OpusFlow grows with you, providing a scalable foundation that adapts to new technologies and business models.

Connect with over 6,000 tools using OpusFlow’s open API

OpusFlow’s Open API enables seamless integration with more than 6,000 external tools, allowing your business to connect accounting systems, analytics platforms, marketing tools, and custom internal software. Data flows automatically between systems, reducing duplication and manual input.

This integration flexibility means OpusFlow fits into your existing technology landscape while acting as the central operational hub. As your business evolves, you can add or change tools without disrupting workflows, keeping your setup scalable, adaptable, and future-proof.

FAQ

Everything you want to know before booking a demo.

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.

Who can I refer to the OpusFlow referral program?

You can refer professional solar installers and companies working with renewable energy technologies, such as HVAC, battery storage, and EV charging. The ideal referral is an installer with 10+ employees who manages multiple projects and could benefit from running their operations more efficiently with OpusFlow.

What is OpusAI and what can it do?

OpusAI is a conversational AI assistant built directly into OpusFlow. Because it has full context of your entire account, every project, schedule, invoice, and BOM, you can ask it to do real work. Generate a margin report, reschedule a week, draft a proposal email, flag overdue jobs, or create a purchase order. In plain language, in seconds.

Do I need technical knowledge to build automations?

No. Automations in OpusFlow are configured through a visual rule builder — you select a trigger, add conditions, and define one or more actions. No code involved. For more complex workflows, pre-configured automation templates give you a proven starting point you can adapt rather than build from scratch. Most teams have their first automations running within an hour of setup.

How does the OpusFlow referral program work?

  1. Complete the form with your own details
  2. Enter the referral’s details via the same form (step 2);
  3. OpusFlow reviews the referral and contacts the referred person
  4. When the referral subscribes to an OpusFlow subscription, both you and the referred installer receive €250.
  5. Terms & conditions apply, you can read the full terms here

What is the process for managing user permissions and roles?

OpusFlow gives you full control over who sees what. With the User Management module you can restrict access per employee, down to individual modules and actions, so your data stays exactly where it belongs.

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.
