Installers lose time by hunting for the right file, resending documents that already exist, and apologising to clients because something slipped through the cracks. OpusFlow puts an end to that.
When someone moves on, so does their filing logic, their inbox threads, and the documents only they knew how to find. You are left rebuilding from scratch and hoping nothing critical is missing.
There are three versions of that contract sitting in different folders, and nobody is quite sure which one the client actually signed. So you send one, the client references another, and the conversation turns into a mess nobody has time for.
You end up emailing large attachments, chasing delivery confirmations, and re-sending things that got buried. There is no clean way to hand over documents without it becoming a back-and-forth.
Documents are stored against the project, not the person. When someone leaves, nothing gets lost.
Every document is stored and updated centrally, so your whole team is always working from the same file.
Documents can be shared instantly from within the project, with full control over who sees what.

Every document you upload is automatically linked to the right project. OpusFlow creates and organises files across employees, projects, customers, and suppliers from a single action. Your team always finds the most up-to-date version without asking anyone.

OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.
Move away from paper and scattered digital files by bringing all your documents into OpusFlow. Quotations, contracts, forms, correspondence and invoices are digitised and stored centrally, accessible from any device. Your whole team works from the same source of truth, reducing miscommunication and keeping every department aligned.

Everything you want to know before booking a demo.
Every ticket has a built-in conversation thread where your team and the customer can exchange messages directly. The full history is stored chronologically and cannot be edited or deleted, so there is always a clear, accurate record of what was said and when. No more hunting through email chains to piece together what happened.
Yes. OpusFlow monitors stock levels across your primary warehouses, service vehicles, and any forward staging locations in real time. Every movement — inbound receipt, outbound deployment, or internal transfer between locations — is recorded in an immutable timestamped log. Items can be tracked by barcode, supplier SKU, or your own internal identifier, so you always know exactly where each product is across your entire operation.
Yes! You can easily attach photos and files directly to your forms, straight from your phone or tablet on-site.
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.
Three-way matching is the process of validating a purchase order against the warehouse goods receipt and the supplier invoice to confirm they all align before payment is approved. OpusFlow handles this automatically, flagging any discrepancies between what was ordered, what arrived, and what the supplier is billing. It removes a significant source of invoice errors and gives your finance team a clean, auditable trail for every purchase.
Yes! At every stage of a project you have a clear overview of the status, budget, timeline and all relevant documents, so you always know exactly where things stand.
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.
Yes. The customer portal displays a visual milestone tracker showing exactly where the project stands, from initial survey through to commissioning. The indicators update in real time as your team progresses the project in OpusFlow, so customers always have an accurate picture without needing to chase your team for an update.
Yes. OpusFlow’s Multi-Entity Finance feature lets you manage multiple companies, labels, or subsidiaries from a single account. Each entity gets its own branding, invoice number sequences, payment terms, and accounting integration. Projects and quotes are automatically linked to the correct entity, so there’s no risk of invoices going out under the wrong logo or routing to the wrong general ledger.
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.
More integrations are added regularly and you can check out all possible integrations here.
Project management software helps you plan, organize and manage your projects from start to finish. OpusFlow is built specifically for sustainable installers, so every feature fits the way you actually work.
You can migrate a large part of your data to OpusFlow via a fixed Excel template. It is worth considering whether all your historical data still needs to be active in the system, as you can always choose to store older data elsewhere and start with a clean slate in OpusFlow.
Yes! All your employees can log their hours directly in OpusFlow via the mobile web app. Time registrations are linked to projects, so you always have a clear picture of project profitability including labor costs.
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.
Yes! All OpusFlow modules work on any device, so filling out forms on your smartphone or tablet is no problem at all.
