FitOutOS: From a Measured Wall to a Client-Ready Quote

A spreadsheet quote is free right up until a price changes and nobody updates the formula. A finish gets swapped, a rate goes up, a module gets substituted mid-project — and the quote a client actually signed no longer matches what the job costs to deliver. That gap is where fit-out and kitchen studios quietly lose margin, one small correction at a time.

FitOutOS is the OS Series' constraint-driven cabinet configurator and quoting engine for kitchen and fit-out studios — built by Xamun and delivered by BlastAsia — purpose-built for the studio caught between a heavyweight CAD-and-catalogue suite built for showroom chains and a spreadsheet that drifts the moment a price changes.

A Brief In, a Costed Concept Out

FitOutOS starts with plain-language brief parsing: a line like "matte white, lots of drawers, around £6,500, splashback and cornice" becomes structured design preferences the engine can act on directly — no form-filling, no translating a client conversation into CAD inputs by hand. From there, constraint-driven auto-layout fills the measured run with valid, fixed-dimension modules around sinks, hobs, and tall units. The layout can never be wrong by construction — no impossible plan, no unbuildable configuration slipping through to a client.

Every brief produces genuinely different options: value, balanced, and storage-led layouts, distinct in module mix and price, generated side by side — so a client is comparing real alternatives, not three versions of the same plan with a different label. Each option arrives with an AI concept render and sketch: a photoreal perspective and a hand-drawn concept sketch generated directly from the brief, client-ready imagery in seconds alongside a written concept — the kind of visual that closes a sale in the room rather than days later.

Drawings That Agree With the Concept

Every layout ships with to-scale elevations, a plan, and a floor plan — a true top-down floor plan, per-run plan view, and 2D elevations, all colour-matched to the chosen finish, so the technical drawings and the concept image never disagree with each other the way a CAD file and a separate rendering package sometimes do.

Pricing That Never Drifts From the Catalogue

Live catalogue-true pricing is where FitOutOS earns its keep against a spreadsheet: materials, finishes, labour, waste, markup, and VAT recompute on every change, with worktop, splashback, panels, plinth, cornice, and handles derived automatically rather than added as a manual afterthought. Revise and re-price instantly carries that through the entire job — swap a finish globally or per module, override a line, lock a unit, and regenerate; the quote and the colour-matched drawings update together, live.

The studio's own catalogue drives all of it. Bring your own catalogue imports modules, finishes, and rates from CSV, with kitchen and office sets included as a starting point — the engine is the asset, the studio's own catalogue is what makes it theirs.

One Board, From Measured to Quoted

A pipeline the studio shares puts every job on one board — draft, measured, concept-ready, in revision, quoted — with role-aware access for designers, estimators, and managers, so a job's status is visible to the whole team rather than living in one person's inbox.

At the end of the process, a branded PDF quotation exports with the studio's own logo and brand: cover, AI concept, elevations and floor plan, itemised or bundled pricing, scope of work, and terms — the quote total always equal to the engine total, with no reconciliation step between what the software calculated and what actually gets sent.

Right-Sized for the Studio in the Middle

FitOutOS isn't scaled down from a showroom-chain CAD suite, and it isn't a spreadsheet with better formatting — it's purpose-built for the studio that needs valid layouts and catalogue-true pricing without a CAD-suite budget or a Windows-only workstation. That covers kitchen studios and showrooms quoting on the spot, fit-out and joinery contractors turning a site measure into a priced proposal without a CAD technician in the loop, cabinet makers running their own modules and rates, and office fit-out businesses applying the same engine to storage walls and credenzas with an office catalogue in place of a kitchen one.

Delivered Through BlastAsia's Engagement Models

FitOutOS is built by Xamun through the Xamun Software Factory and delivered by BlastAsia through its Turnkey or xDD engagement models, with catalogue and module configuration scoped as part of onboarding — and, as a source-available, perpetually licensed product, owned outright by the studio rather than rented seat by seat.

If your studio is still quoting off a spreadsheet that drifts or a CAD suite that's overkill for the size of the job, let's talk through how FitOutOS fits.
