Interior Design Web App Development for Project Delivery
A browser-based workspace where designers, site supervisors and clients see the same project status, drawings and approvals. Built for studios running several sites at once.
This page is about interior design web app development: internal dashboards and client portals that replace WhatsApp groups, Excel sheets and email attachments for running live projects. It suits studios and contractors with five or more concurrent sites. It is not a marketing website, and it is not a mobile app, though the two can share one backend.
The real problem in interiors is rarely design. It is that a client approved the laminate on a call, the carpenter heard something else, and nobody can prove which version was final. A web app gives every decision a date, a name and a file attached to it. Plain records end most of those arguments early.
What interior studios need from a project web app
One source for drawings and approvals
Layouts, elevations and material choices go through revisions. Each file needs a version, an approver and a timestamp so a disputed change can be traced in seconds.
Stage-wise milestones and payments
Interior contracts are usually paid in stages tied to design sign-off, civil work, carpentry and handover. The app should show what is due, what is raised and what is received, with GST invoices.
Site updates from supervisors
Supervisors send photos and notes from the flat itself, often with weak signal inside a half-built building. Uploads must queue and retry rather than fail silently.
A client view that is deliberately limited
Clients should see progress photos, pending decisions and invoices. They should not see your vendor rates, margins or internal comments.
What we build for interior design teams
Client portal with approval trail
Clients log in by phone OTP, review designs, approve or comment on each item and download invoices. Every approval is stored with date and version so scope changes are visible.
BOQ and quotation builder
Build a bill of quantities from your own rate list of materials, labour and hardware. Revisions create a new version while the earlier quote stays on record.
Site task board for supervisors
Tasks per room, assigned to carpenters, painters or electricians, with photo proof on completion. The studio owner sees delays by site without calling each supervisor.
Vendor and purchase tracking
Log purchase orders for plywood, tiles and fittings against each project, with delivery status and payables. Costs roll up so you can compare quoted and actual spend.
What it costs
This is the web app anchor with the launch discount applied. Cost moves with the number of user roles, BOQ complexity, accounting export needs and any mobile-friendly supervisor screens, and is fixed in writing after discovery.
Questions we get asked
Can the app work for a studio with only five or six staff?
Yes, provided you run enough concurrent projects to feel the coordination pain. Small teams usually start with client approvals, BOQ and stage payments, then add vendor tracking later. We scope version one around the two workflows that lose you the most time.
Can our rate list and BOQ format be reproduced exactly?
Yes. We build around your existing item codes, units and rate lists instead of forcing a template. During discovery we review a few of your real quotations so the printed PDF matches what clients already receive from you.
How do clients access it without installing anything?
They open a link in the phone browser and sign in with an OTP sent by SMS or WhatsApp. No download is needed. If clients later ask for an installable app, the same backend can support a mobile app.
Who owns the project data and drawings stored in it?
You do. The code and the data belong to your business, and we hand over a full export on request. During discovery we note where files are hosted and who holds the admin access, so you are never locked in.
