Yes. OpusFlow connects with Google Workspace and Microsoft 365 for calendar and email, external accounting packages via API export, wholesale product catalogues via 2BA, and payment processing via Mollie for automated SEPA billing. It also connects to Zapier for endless possibilities.

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.

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.

When a project is confirmed, OpusFlow reserves the required stock against that project automatically, based on the Bill of Materials. The reservation is hard — meaning those items cannot be allocated to another project, eliminating the double-allocation problem that causes install-day shortages. Stock levels across your warehouses, vehicles, and staging locations all update in real time so you always have an accurate picture of what is actually available.

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.

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.

Yes. The customer portal carries your branding, so the experience your customer has is consistent with the rest of your communications. It reinforces your company’s identity rather than surfacing OpusFlow’s.
