Spatium — Interior Design Studio OS
Spatium is the business operating system for interior design studios — connecting your projects, vendors, procurement, and finances in one platform powered by Odoo 19. Know what every project actually costs you, in real time. Built for studios running 5 or more simultaneous active projects in KSA, Egypt, and the GCC. 6-week go-live guarantee. Fixed price. No surprises.
Most interior design studios deliver stunning work. But at the end of a project — when the client is happy, the space is finished, and the final invoice has gone out — many studio owners still can't answer a basic question: did we make money on that one?
Material costs tracked across 12 vendor conversations. Contractor payments buried in three different WhatsApp threads. Milestone invoices that went out late because nobody connected project delivery to billing. The margin you expected exists only on paper — because the data that would confirm or deny it is scattered across tools that don't talk to each other.
The Project That Looked Profitable Wasn't
Interior design studios run some of the most operationally complex project-based businesses that exist. The result of managing that complexity on disconnected tools is predictable — and expensive:
Material costs only visible at project close — by which point the overspend is already done and nothing can be done about it
Vendor quotes in WhatsApp, decisions verbal, agreements undocumented — invoices arrive with different numbers three weeks later and there's no baseline to dispute them
Milestone invoices sent two weeks late because no one formally connected project delivery to billing — on a four-milestone project that delay compounds into a serious cash flow problem
Eight active projects with no unified view — the status of each living in someone's head, a folder on a shared drive, and a WhatsApp chain. That absence of visibility is itself a cost
What Spatium Is
Spatium is a purpose-built business operating system for interior design studios with 5–30 staff running 5 or more simultaneous active projects in KSA, Egypt, and the GCC. Built on Odoo 19, it connects every part of how your studio operates — from new business pipeline to final project handover — in one unified platform, implemented in 6 weeks at a fixed price.
Every Part of Your Studio's Business. One Platform.
Client Pipeline & Proposal Management
Every prospect in a structured pipeline. Proposals with agreed values, stages, and follow-up actions. When a project is won, it moves directly into the project module — no re-entry, no data gaps. Your business development process becomes a system, not a memory exercise.
Who it's for
Built for the people who'll run it.
Studio Founders & Creative Directors
You're winning beautiful projects and your reputation is growing — but you still don't know, at any given moment, whether you're profitable. Spatium gives you the financial clarity that creative success alone can't provide: real margin on every active project, pipeline value at a glance, and the knowledge of which client relationships are driving the most revenue. Without waiting for your accountant to compile a report that's already two weeks out of date.
Senior Project Managers
You're managing six active projects at once — coordinating vendors, tracking deliveries, managing client expectations, and keeping everything on timeline. The admin overhead is crushing the time you need to actually manage outcomes. Spatium becomes your operational command center: every project, its phases, vendor POs, outstanding tasks, and billing milestones in one place. Less time managing information. More time managing results.
Architecture
What's inside the blueprint.
The components we engineer when we build this solution. Each one is documented, tested, and handed over with the rest.
01
Every prospect in a structured pipeline with proposal values, stages, and follow-up actions. When a project is won, it moves directly into the project module — no re-entry, no gaps. Win rates and pipeline value visible at a glance. Your business development process becomes a system, not a memory exercise.
02
A project for every client engagement with phases defined at the start: concept, design development, material specification, procurement, execution, handover. Milestones linked to billing. Real-time budget tracking showing design fee revenue against all associated costs. When you open a project, you see exactly where it stands — financially and operationally.

01
Discovery & Studio Mapping
In a focused 30-minute discovery call we map your current workflow — how you manage projects, how you procure materials, how you bill clients, and where the operational pain is sharpest. We identify the exact configuration Spatium needs for your studio's reality and confirm fit before any work begins.
02
Platform Configuration
We configure Spatium around how your studio actually works: your project phases and milestone structure, vendor categories and PO approval workflow, client billing model, and chart of accounts for KSA or Egypt VAT compliance. You receive a system that reflects your business — not a blank ERP you need to figure out.
03
Data Migration & Parallel Testing
We migrate your vendor records, client data, and up to two years of project history from your current tools. We run both systems in parallel during testing — confirming every figure, every vendor record, every billing milestone — so the transition is verified before it is final.
04
Team Training & Go-Live
Dedicated training sessions for project managers, procurement, and finance — each role trained on their specific workflows within Spatium. We confirm everything works before a single real project is entered. From go-live day, your procurement is tracked, budgets are visible, and milestone invoicing runs on schedule. The operational chaos does not migrate with you.
05
30-Day Hypercare Support
For 30 days after go-live, the QueuesHub team is actively engaged — monitoring performance, resolving any friction in day-to-day use, and ensuring your team is fully confident in the system. The first month is when habits form. We stay close until Spatium is simply how your studio works.

FAQ
Frequently asked questions
What is the best business management software for interior design studios in Saudi Arabia?
Spatium by QueuesHub is a purpose-built business operating system for interior design studios in KSA and Egypt, powered by Odoo 19. It connects project management, vendor procurement with formal PO management, milestone-based client billing, accounting, and HR in one platform. It includes native ZATCA Phase 2 e-invoicing compliance and Egyptian VAT handling. Implementation takes 6 weeks from kickoff and includes full team training and 30 days of hypercare support. It is built for studios with 5–30 staff running 5 or more simultaneous projects.
How do interior design studios automate milestone billing and avoid late invoicing?
Spatium automates milestone billing by linking client invoice triggers to project phase completions. When a project manager marks a milestone as complete — design concept approved, materials procured, execution signed off, or final handover delivered — the corresponding client invoice is automatically generated and sent. No manual chasing of finance. No invoices forgotten because someone was managing six other projects simultaneously. Cash flow improves from day one of go-live because the billing cycle is connected to actual project delivery, not to someone's memory.

Project & Engagement Management
A dedicated project for every client engagement, with phases defined at the start: concept, design development, material specification, procurement, execution, handover. Milestones linked to billing. Real-time budget tracking showing design fee revenue against all associated costs. When you open a project, you see exactly where it stands — financially and operationally.
Vendor Quotation & Purchase Order Management
The most important module for design studios. Request quotations from multiple vendors simultaneously and compare them in one view. Issue a formal purchase order with agreed price, scope, and delivery terms before any work begins. Every PO linked to the project it serves. Material costs flow automatically into project cost tracking. Vendor disputes become rare because the agreed terms are always on record.
Milestone-Based Client Billing
Define your billing milestones at project start — design fee instalment, procurement advance, execution sign-off, final handover. When the project manager marks a milestone complete, the client invoice is triggered automatically. No chasing finance. No forgotten billing. No cash flow gap between delivered work and collected payment. Recurring retainer clients invoiced automatically every month.
Financial Control & Real P&L per Project
Every design fee, material cost, contractor payment, and operational expense connected to the project it belongs to. P&L per project visible without asking your accountant to reconstruct it from five different files. VAT-compliant for Saudi Arabia — ZATCA Phase 2 e-invoicing included — and Egypt. Month-end close becomes a review, not a reconstruction.
Team, HR & Contractor Management
Employee profiles, contracts, leave management, and payroll for your in-house team. External contractors managed as vendors — their costs linked to the projects they serve. A resource view showing which team members are committed to which projects, so you know before you promise a client a start date whether you have the capacity to deliver.
What Spatium Replaces
The average interior design studio uses 4 to 6 separate tools to manage what should be one connected workflow. None of them share data. Every handoff between tools is a manual step — and manual steps are where errors, delays, and lost money live. Spatium consolidates everything in one platform: Excel project trackers replaced by a live connected project module, WhatsApp vendor negotiations replaced by formal POs with agreed terms on record, manual milestone invoice reminders replaced by automatic billing, and separate accounting software replaced by integrated financial reporting that connects directly to project activity. All for less than studios are currently spending on fragmented tools.
From Your First Call to Your Studio Going Live — In 6 Weeks
Discovery (Week 1): A focused 30-minute call maps your current workflow — projects, procurement, billing model, and where the pain is sharpest. We identify the exact configuration Spatium needs for your studio and confirm fit before any work begins. You don't get a generic demo. You get a specific answer.
Configuration & Migration (Weeks 2–4): We build Spatium around your actual workflow — your project phases and milestone structure, vendor categories and PO approval workflow, client billing model, chart of accounts for KSA or Egypt compliance. We migrate your vendor records and up to two years of project history. We run both systems in parallel and verify every figure before the transition is final.
Training, Go-Live & Hypercare (Weeks 5–6 + 30 days): Role-specific training for project managers, procurement, and finance. Gradual go-live with parallel confirmation that everything works before real projects are entered. Then 30 days of active hypercare support — the QueuesHub team stays close until Spatium is simply how your studio works.
Saudi Arabia Is Building at a Scale the Design Industry Has Never Seen
Vision 2030 is generating an unprecedented volume of premium residential, hospitality, commercial, and cultural projects across the Kingdom — NEOM, The Red Sea Project, Diriyah Gate, and thousands of high-end developments in Riyadh, Jeddah, and the Eastern Province. Every one represents design work. Interior design studios serving this market are growing faster than their operational infrastructure can support.
Studios that were managing 3 active projects two years ago are now managing 10. The WhatsApp groups and Excel trackers that worked at lower volume are visibly breaking. The studios that build operational foundations now — structured procurement, milestone billing, real project cost visibility — are the ones that will scale with the market without losing control of their margins. Spatium is built specifically for studios operating in KSA and Egypt. ZATCA Phase 2 e-invoicing (هيئة الزكاة والضريبة والجمارك), multi-currency for international clients — all configured as part of the standard setup.
Built for Studios That Have Outgrown Managing Complexity by Memory
If your studio has 5–30 people, you're running 5 or more active projects simultaneously, and you've experienced at least one project where actual costs significantly exceeded your original budget — Spatium was built for you. Not a solo designer, not a studio of three. Not someone looking for an afternoon self-configuration. A studio ready to run its business with the same care it brings to its craft.
Finance & Operations Managers
Every month you spend days reconciling what was spent, what was invoiced, and what was received across projects tracked in five different places. Month-end shouldn't be this hard. With Spatium, procurement costs flow directly from purchase orders into project accounts. Invoices are triggered by milestones, not by someone remembering to send an email. Month-end becomes a review of clean, connected data — not a reconstruction from scattered records.
Multi-Project Studio Leaders
You're running eight or more client engagements simultaneously — each at a different stage, each with its own vendors, budget, and timeline. The status of each lives in someone's head, a folder on a shared drive, and a chain of WhatsApp messages. Spatium gives you a unified view across your entire portfolio: which projects are on budget, which have outstanding invoices, which have pending procurement decisions, and which have team capacity to take on new work. The absence of that visibility was itself a cost.
03
Request quotations from multiple vendors simultaneously and compare them in one view. Issue a formal purchase order with agreed price, scope, and delivery terms before any work begins. Every PO linked to the project it serves. Material costs flow automatically into project cost tracking. Vendor disputes become rare because agreed terms are always on record.
04
Define billing milestones at project start — design fee instalment, procurement advance, execution sign-off, final handover. When the project manager marks a milestone complete, the client invoice is triggered automatically. No chasing finance. No forgotten billing. Recurring retainer clients invoiced automatically every month. Cash flow improves before anything else changes.
05
Every design fee, material cost, contractor payment, and operational expense connected to the project it belongs to. P&L per project visible without asking your accountant to reconstruct it from 5 different files. VAT-compliant for Saudi Arabia — ZATCA Phase 2 e-invoicing included — and Egypt. Month-end close becomes a review, not a reconstruction.
06
Employee profiles, contracts, leave management, and payroll for your in-house team. External contractors and freelancers managed as vendors — their costs linked to the projects they serve. Resource view showing which team members are committed to which projects, so you know before you promise a client a start date whether you have the capacity to deliver.
Is Odoo 19 suitable for managing interior design projects and procurement?
Yes — Odoo 19 is a business operations platform, not manufacturing software. The modules configured in Spatium — project management with milestone tracking, vendor quotation and PO management, milestone-based invoicing, and integrated accounting — map directly onto how an interior design studio works. QueuesHub configures Spatium specifically for interior design workflows, so studios are not adapting a generic system. Each project in Spatium is its own entity with its own phases, vendors, budget, and billing structure. No two projects need to look the same. The framework is consistent; the content of each project is entirely the studio's own.
