FAQ

Everything you want to know before booking a demo.

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.

Can I link my billing to my financial package?

Yes! OpusFlow connects with a wide range of accounting software. We have extensive experience integrating with platforms like Exact, Holded and Quipu, and through our Zapier integration you can link virtually any financial package.

How can tickets be created in OpusFlow?

Tickets can be created through several routes: logged manually by your team after a phone call, parsed directly from an incoming email, or submitted by the customer themselves through the Customer Portal. However a request comes in, it ends up in the same structured queue — so nothing gets handled informally through a personal inbox and nothing falls through the cracks.

Can I participate in the OpusFlow referral program?

Anyone can take part in this referral program, whether you are an existing customer or not. Simply complete the referral form with your own details and the referral information and we’ll take care of the rest.

Can you make a strip schedule in the planning module?

Yes! Within OpusFlow you can easily create a strip schedule, with tasks and subtasks on the vertical axis and time on the horizontal axis. This way you always have a clear overview of what needs to be done and when.

Can I transfer data from my current software package to OpusFlow?

Yes, data migration is part of our onboarding process. Our import module lets us transfer almost any database from your current software, and your account manager will guide you through every step. Book a free demo to get started.

Which 3D scanning tools does OpusFlow work with?

OpusFlow accepts scans from iPhone Pro (via LiDAR), Matterport, Polycam, and other scanners that export in OBJ, STL, GLTF, or GLB formats. The scan is processed directly in the browser — no file upload to a server is required, which keeps the process fast and keeps your customer data on-device during the calculation.
