A note
From the founder
This started at our kitchen table. My wife is an architect, and for years I watched her — and the interior designers she worked alongside — juggle clients, selections, approvals, vendors and invoices across a dozen disconnected tools. The software built for our industry was designed for firms that bill millions, not for the independent studios doing most of the beautiful work. So I drew the system I wished existed: relational, opinionated, set in the same calm palette you'd want in a client's drawing room. The Interior Designer OS is that system, tuned for the way you actually run a studio — one fabric, one approval, one project at a time.

01The friction · in three movements
Three things slow every studio down.
None of them are design problems.
They're operations problems — the kind no school taught you, the kind that quietly eat your evenings and your margin.
"FF&E in spreadsheets that splinter the moment a sofa changes."
"Lead times scattered across email, WhatsApp, and a paper diary."
"Approvals buried in threads you can no longer find."
02The system · eight rooms, one house
Eight databases.
Everything related.
Change a vendor's lead time and it flows through every selection that references them. Approve a finish and the room status updates itself. The relations are the point.

Clients
Households, preferences, history — one linked record per relationship.

Open →03The method · DRAW
Four phases.
One method.
Every project moves through the same rhythm. Every database, template, and prompt is organised around it — so nothing falls through the gaps between concept and handover.
- 01DDiscover the brief
Capture the client's vision, budget, and non-negotiables before a single sample is pulled. A Design Brief template that asks the questions you forget to ask at 6pm on a Friday.
- 02RRefine the scheme
Iterate through concept and schematic phases. Every revision tracked, every selection versioned, every comment threaded against the room it concerns.
- 03AApprove and lock
Formal, defensible sign-off. Room by room, line by line. A single source of truth the client signs and the contractor reads.
- 04WWrap and hand over
Snag lists, final invoices, warranties and care notes — bundled, formatted, delivered. The handover that makes them call you for the next house.
04Inside the workspace · three rooms
A walk through the rooms you'll live in.
Pl. 02 · Selections
An FF&E board you can defend.
Every piece linked to a vendor, a room, a status. Filter by lead time. Sort by approval. Total per room rolls up to the project.
Pl. 03 · Approvals
Sign-off, in writing.
Formal approval records by phase. Date-stamped, room-scoped, exportable. A paper trail that ends the 'I never agreed to that' conversation.
Pl. 04 · Vendors
A rolodex with memory.
Suppliers, trade discounts, lead times, terms — searchable, rankable, linked to every selection you've ever specified from them.

On using it
"It is the first tool that feels designed. We replaced four spreadsheets, two Google Docs, and a folder of PDFs in an afternoon. The client portal alone has saved us a difficult conversation a week."
