JoineryCore is built by Skylon Development LTD — but it didn't start in an office. It started on a workshop floor.
That floor belongs to Prime Sash Windows, a London joinery business — and the living proof that JoineryCore is built by people who know the trade inside out. Prime Sash makes bespoke timber sash and casement windows, hand-built in Britain from premium hardwood and Accoya, glazed with high-performance passive glass and backed by a 10-year warranty. Every window is FENSA-registered and built to PAS24 security standards — and Prime Sash is the only sash window company in the UK with a live 3D configurator that lets you design and price your windows instantly online.
Running a workshop to that standard means dealing every day with exactly what our customers deal with: quoting jobs, ordering timber, scheduling production and keeping a team organised. We built JoineryCore because the tools we needed didn't exist. Spreadsheets, whiteboards and scraps of paper don't scale — so we made software that does, designed around how a real workshop actually works.
Why that matters
JoineryCore isn't a generic business tool bent to fit joiners. It's built by joiners, for joiners — shaped by the realities of running a workshop, not by a feature list dreamed up in a meeting room.
From the floor
Every feature comes from a real problem we hit running our own workshop.
One screen
Estimating, production, stock, team and finances — together, not scattered.
No fluff
Honest software with no false promises. If we wouldn't use it, we don't build it.
