Run your window and door
factory on one platform
Go from a visual window design in the browser to a cut list on the production floor — without spreadsheets, redrawn plans, or chasing updates on WhatsApp.
Trusted by window and door manufacturers
Stop running the factory on guesswork
Most fabricators lose hours and margin in the gap between the design and the floor. Vinstra Flow closes it.
The old way
- Quotes built by hand in Excel, priced from memory
- Every design redrawn three times across teams
- No real idea what is actually on the factory floor
- Inventory lives in someone's head, not a system
- Updates chased through WhatsApp and phone calls
With Vinstra Flow
- Design once and quote instantly, priced automatically
- One drawing flows to BOM, cut list, and production
- A live production board everyone can see
- Stock that updates itself as jobs are built
- One source of truth from enquiry to install
Everything the factory needs, in one place
Eight connected modules that replace the stack of spreadsheets, drawings, and side apps you use today.
Design Canvas

Instant Quotations
Priced automatically from the design — a customer-ready quote in minutes.
Bill of Materials
Every profile, bead, gasket, and fitting listed and costed from one drawing.
Production Planning
Turn orders into cut lists and schedule jobs across the factory floor.
Inventory
Stock levels that update themselves as jobs are quoted and built.
Installation & Site Tracking

Fabricators who stopped firefighting
“We used to spend a full day building a quote from Excel. Now the design gives us a priced quote and cut list before the customer has left the showroom.”
“The production board changed how the floor runs. Everyone can see what's next, and nothing gets fabricated twice because a drawing changed.”
“We fabricate aluminium and timber, and Vinstra Flow handles both without workarounds. Bar optimisation alone paid for it in the first month.”
“Stock finally matches reality. Inventory updates as we build, so we stopped running out of beads and gaskets mid-run.”
Questions, answered
It runs the whole factory from one platform. You design a window or door on a browser canvas, and Vinstra Flow instantly produces a priced quote, a full bill of materials, and a cut list — then carries that same data through production planning, inventory, installation, and invoicing.
Window and door manufacturers of every size, from a small workshop quoting a few jobs a week to a factory running multiple production lines. If you design, fabricate, and fit windows or doors, it's built for you.
Yes. Vinstra Flow supports uPVC, aluminium, and wooden window and door businesses. Each material has its own profile systems, allowances, finishes, and optimisation rules built in — you're not forcing a uPVC tool to fit an aluminium line.
Most factories are quoting from Vinstra Flow within days. We load your profile systems, pricing, and suppliers with you, so the platform reflects how your factory actually works before you go live.
Pricing is a straightforward monthly subscription based on the size of your team and the modules you use. There's no per-quote charge and no long lock-in — book a demo and we'll size a plan to your factory.
