Interior companies, residential designers, and commercial fit-out firms trust InteriorOS to replace WhatsApp, Excel, and Tally with one connected platform.
See what's new in InteriorOSYou're running 5 projects across 3 cities. Your supervisor sends updates on WhatsApp. Your accountant tracks payments in Tally. Material orders live in Excel. Nothing talks to anything.
Updates buried in group chats, site photos lost in media folders, no search, no accountability. Critical decisions vanish in scroll.
Your budget spreadsheet says ₹18L. Your site spent ₹22L. You find out a month later. By then, the margin is gone.
You call each supervisor individually for updates. Labour attendance is a paper register. Material approvals happen verbally. Nothing is trackable.
Stop losing time to chaos. InteriorOS brings structure to every step.
See how InteriorOS solves this →Site management, financials, designer tools, CRM and team — every module purpose-built for Indian interior studios. No plugins. No setup. No training.
Project timelines with milestones, daily progress reports with photos, labour attendance, and task assignments — one thread per project.
Payment in/out tracking per project, expense submissions with approval workflows, and a full studio ledger across all projects. Share payment summary PDFs with clients in one tap.
No generic project app has this. Laminate library with room-by-room selection, whiteboard for sketches, material requests with photo approvals, and a vendor directory with running balances.
Lead capture with follow-up reminders, appointment scheduling, quotation drafting, invoice generation, and notifications when payments are due — all in one place.
Add multiple supervisors, assign them to projects, control what they see. Team members can join other organizations too. Multi-level approvals ensure nothing gets spent without your sign-off.
Each project includes a dedicated client view — progress, approvals, payment status, and DPR photos. Internal margins, vendor rates, and team chat stay private. One project. Two perfectly separated channels.
Margin protection by design — your client never sees what you don't want them to.
Stop forcing generic project tools to fit interior design workflows. InteriorOS speaks your language.

"The toolkit alone is worth the price. My team calculates paint and tile requirements directly from the app without calling me. The material approval workflow has completely stopped unauthorized purchases."
"We transitioned from Excel and WhatsApp groups to InteriorOS in 2 days. Having the CRM, financials, and project timelines in one single dashboard gives me immense peace of mind. Highly recommended."
"The GPS labour attendance feature is a game-changer. We no longer rely on paper registers that get lost or fudged. I know exactly who is at which site, every single day."
