For Indian Interior Designers

Stop losing ₹50,000+ per project to

Vismayum is a project management tool built specifically for Indian interior designers. Track BOQs, manage vendors, bill clients correctly - all in one place.

From Sanskrit vismaya, which means wonder. The feeling your spaces create. The chaos of running them shouldn't get in the way.

Currently in development

Every project. One place.

BOQs, change orders, vendor POs, GST invoices - all connected, all tracked, nothing missed.

Mockup for illustration purposes only. Final UI may differ slightly during development. All data shown - project names, amounts, vendor details - are fictional test data.

The Problem

If this sounds familiar, Vismayum is for you.

01

BOQ Version Chaos

You send Version 7 to the client. Their spouse is looking at Version 5 from their inbox. Nobody knows which is final. WhatsApp has 7 different Excel files floating around.

02

Change Orders Vanish

"Actually, let's change the marble to tiles." "Add an extra wardrobe here." Every project has 10-15 changes. Half never get billed because there's no record.

03

No Vendor POs

Everything happens on WhatsApp. Verbal agreements. When the carpenter delivers different quality or less quantity, you have zero proof of what was agreed.

04

GST Invoice Errors

CGST or IGST? Same state or different state? TDS 1% or 10%? You create invoices manually in Word and hope the numbers are right. Your CA finds errors 3 months later.

05

Money Gets Lost

Client paid ₹6L for material procurement. You paid carpenter ₹2L, marble vendor ₹1.5L, electrician ₹80K. What's left? You scroll through bank statements trying to reconcile.

06

Design Files Everywhere

Floor_Plan_v3_FINAL_revised.dwg. Render_kitchen_NEW.jpg. The client approved something - but which version? You're sharing 50MB files over WhatsApp and praying the right one gets used on site.

07

Site Updates Pile Up

You take 80 site photos a week. They sit in your camera roll, scattered across WhatsApp groups, lost in the scroll. The client asks 'how is the kitchen coming along?' and you spend 20 minutes searching.

How it works

One system. Every stage of your project.

Create a professional quotation

Build a detailed quotation room-by-room in minutes — not hours. Select from pre-built item templates, adjust rates, and Vismayum auto-calculates GST. CGST + SGST or IGST, depending on where your client is.

Send a PDF to your client. Once approved, convert the quotation to a live project in one click — BOQ pre-filled, payment milestones set, nothing re-entered.

Track your BOQ with version control

Build your BOQ room-by-room. Every line item, every rate, every quantity. When the client asks for changes, create Version 2. Version 10. Vismayum tracks them all — you always know what the latest approved version is.

Send a single approval link to your client. They approve on their phone, timestamp recorded. No more 'I never agreed to this' disputes.

Who it's for

Built for Indian interior designers.

Freelance designer

If you're a freelance designer doing 4-8 projects a year at ₹5-15 lakh each, Vismayum helps you stay organized without hiring an admin.

Small studio

If you run a small studio with 3-15 people doing 10-25 projects a year, Vismayum becomes your single source of truth so your team stops working in scattered Excel files.

Tired of disputes

If you're tired of disputes at project end because clients don't remember what they approved and vendors claim they delivered what you ordered - Vismayum gives you a paper trail.

Pricing

Simple pricing. No hidden costs.
