is broken.
Disconnected systems. Orders re-typed by hand. Deposits chased for weeks. Nobody knows what's coming next. It costs the trade money — and its reputation. FramesHub connects the whole chain back together.
A real system that works.
You already know how this goes.
The people aren't the problem. The disconnect between them is — and everyone in the chain pays for it.
The order gets re-typed at the factory — and something's wrong.
Fitter and factory blame each other. The customer just waits.
Deposits chased for weeks. Cash flow on a knife-edge.
No idea what's coming next week. Production is guesswork.
Remakes, delays, and profit quietly leaking at every handover.
The homeowner's left in the dark — and fenestration gets the blame.
Sound familiar? It doesn't have to.
One connected chain. End to end.
A doorstep survey becomes a real production order. The factory builds it — no re-keying, no queries. Everyone gets paid on time. And for the first time, the whole chain can see itself.
One platform. Three products. Every link.
Each part of the trade gets the tool built for them — connected to the same chain.
FramesHub Lite / Pro
Sits on a tablet, written by a fitter who understands the process — simple to use. Start with Lite: cheaper, and it does everything you want, replacing the paper and notebooks. Measure once, enter the dimensions, done. Then step up to Pro in-app — the complete business in a box, from installations to accounts.
FramesHub EXP
Two progressive versions, same design — no new learning curve. Grow to a full ERP and retire the legacy system in your own time. Deploys in days. No massive, expensive infrastructure upgrade — everything in one box, running alongside the system you already have. The factory never stops.

Is it worth it?
Every re-keyed order, every remake, every chased deposit, every week of guesswork — it all costs you, in money, time and trust. FramesHub is built to give it back. It doesn't add another system to wrestle with; it removes the gaps between the ones you already have.
We're not showing everything. Yet.
One survey. Two outputs — the customer's quote and the factory's spec, generated together. There's a lot more under the hood.
Built by people who've lived the problem.
Sitim began as a software company delivering global solutions — design to implementation. Its senior partner had spent years in fenestration before that, and knew exactly where the industry breaks.
"I came back to the industry after a few years away — and found that nothing had changed. The same disconnects, the same waste, the same 'that's just how it's done.' That was the moment I knew it had to be built."— Tim, Senior Partner
So a group of partners came together — best placed to design, program and build a system that covers every attribute of the industry. Between them they bring decades from:
Experience drawn from the UK, America, Japan, Germany and France.
We know the industry is inflexible, and that the software thrown at it has too often made things harder, not easier — longer waits, more friction. And expecting a window company or factory to carry an IT department is unrealistic; the cost alone rules it out. So FramesHub takes those headaches away — truly automated systems that quietly do the work, removing the reliance on management teams forever fighting to keep afloat against a flood of issues.

Common questions
A quick sample — see the full set, split by audience, on the FAQ page.
What is FramesHub?
FramesHub is window quoting and fenestration software that connects the whole chain — the fitter's quoting app, the factory's production system (FramesHub EXP) and the profile company's insight platform. A doorstep survey becomes a real, on-spec production order instantly, without needing to draw anything out or send emails to the factory — direct, fast and functional.
Is there window quoting software for fitters and window companies?
Yes. The FramesHub app is window quoting software, originally built for fitters and retail window companies — shaped by listening to a selection of them about the pitfalls they face today, chiefly the wait for a quote from the factory's processing team and the pressing need to cut that time. Produce professional quotes in minutes on a tablet, take payment, and send a real order straight to the factory. Start on FramesHub Lite and step up to Pro as you grow.
What software do window factories use to run production?
FramesHub EXP is fenestration factory software that quotes, produces, despatches and tracks in one box — running alongside the system a factory already has, with no massive or expensive infrastructure upgrade. And if your current supplier doesn't have it yet, that's fine — ask them to make it available.
Does FramesHub work for profile and systems companies?
Yes. The FramesHub Profile System gives profile companies live demand, pipeline and insight across the chain — statistical only — so they can plan production against real demand instead of guesswork.
When does FramesHub launch and how much does it cost?
FramesHub launches on 8 November 2026. Pricing is designed to pay for itself, with founding-member rates for early registrations — register your interest to hear first and lock in the founding rate.
