Most installation companies don’t struggle with doing the work. They struggle with getting paid for it. Invoices go out late, payment terms get forgotten, and the admin piles up while the next job is already underway. OpusFlow provides a solution to it.
You pull hours from a timesheet, materials from a spreadsheet and project notes from your inbox. By the time the invoice is ready, something is wrong, something is missing, or it is just too late.
The work is finished but the invoice is still sitting in a draft. Between the busyness of the next project and the back-and-forth to gather the right details, sending it on time just never happens.
Somewhere there are unpaid invoices. You just don’t know exactly which ones, how long they have been outstanding, or how much it adds up to. Chasing them happens when someone remembers.
Hours, materials and project data come together in a single invoice view. You bill what was actually done.
Create and send a complete invoice in minutes, straight from the project. No delays, no drafts.
Your financial overview shows outstanding invoices, payment volumes and margins in real time.

OpusFlow’s Email Builder lets you create professional invoice emails using a block-based editor. You don’t need experience in design. Set up templates for different invoice types, add dynamic variables like project number and client name, and send directly from the project view with one click.
OpusFlow connects natively with Google Workspace, Microsoft 365, Exact, Mollie, and more, so your team hits the ground running, not starting over.
OpusFlow links your invoices directly to the project they belong to. Hours registered, materials used and bill of materials data are all visible on the invoice screen, so your billing team has full context without switching between modules. Prepayments are tracked separately in the overview, keeping your totals clear at every stage. You invoice what was actually done, nothing more, nothing less.
Not every project is billed the same way. OpusFlow lets you split invoices into milestones, in exact euro amounts or percentages, and set your own payment terms per invoice. You can add early payment discounts and select alternate billing addresses directly in the invoice dialog. Your billing follows your agreements, not the other way around.

OpusAiis an agentic AI built into OpusFlow that can take action, not just answer questions. You can ask it to generate a labour cost report for a specific period, flag timesheets awaiting approval, summarise outstanding purchase orders, or pull a project margin breakdown for a client meeting. Because it has full access to your live OpusFlow data, the outputs are accurate and actionable, not generic summaries. It’s currently rolling out to early adopters, with a broader release to follow.
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.

OpusFlow integrates directly with Mollie to handle SEPA Direct Debit payments. When a customer signs the contract, they authorise a direct debit mandate at the same time. From that point, payments are collected automatically on the billing schedule without any manual chasing, payment links, or follow-up required from your team.
When a contract is ready to send, the customer receives a secure magic link by email. They can open it on any device, review the contract, sign digitally, and authorise their payment mandate — all without creating an account or needing a password. The whole process is designed to be as frictionless as possible so that signing does not become a reason for delay.
OpusFlow runs a billing engine every night that checks all active contracts and automatically generates invoices for any that are due. There is no manual step required and no risk of a billing run being forgotten because someone was on holiday. The system also includes built-in safeguards that prevent a customer from ever being billed twice for the same period.
Both options are available. OpusFlow ships with out-of-the-box dashboards pre-configured for the metrics most installation businesses need immediately — project pipeline velocity, revenue forecasting, team capacity, and live stock levels. If you need something more specific to how your business works, you can build custom dashboards using a drag-and-drop widget builder with charts, numeric counters, prioritised lists, and data tables.
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.
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.
Yes! You can design your invoices entirely in your own corporate identity. Logo, layout and colors, everything is on your terms.
Yes! Payment terms in OpusFlow are fully flexible, so you set them exactly the way your business works.
When a project reaches the invoicing stage, OpusFlow pulls the line items directly from the project’s Bill of Materials and generates the invoice automatically, with correct quantities, pricing, and totals already populated. For service contracts, you set a billing frequency at the start and the system generates and sends invoices on schedule without anyone triggering it manually. A built-in dry-run mode lets you simulate a billing cycle before it goes live.
