How to Start an Interior Design Business in India: Skills, Pricing, Contracts, GST and Growth

India’s housing boom has created strong demand for interior designers. New apartment owners want modular kitchens, wardrobes, false ceilings and lighting planned properly; offices, clinics, cafes and shops want spaces that work and look good. Interior design is also one of the best-paid small professional businesses in India, and one where a solo designer can grow into a studio with a team. This guide explains how to start an interior design business in India, from licences and costs to finding your first customers.

This guide explains how to start, how to price and protect your work, and how to grow.

Key points

• You don’t need a licence to work as an interior designer in India, but only people registered with the Council of Architecture can call themselves "architects".
• Your portfolio wins clients. Start with real projects, even small ones, and photograph them well.
• Decide early whether you’ll offer design only, or design and execution (turnkey). Execution earns more but carries far more risk.
• Always use a written contract with scope, fees, timelines and payment milestones.
• Design services attract 18% GST. Register once your turnover crosses ₹20 lakh in most states, or earlier if your clients are businesses.

The market in numbers

Interior design falls within what MoSPI’s surveys call professional, scientific and technical services, alongside architecture, accounting, consulting, photography and other professional businesses. In 2023-24 there were about 6.9 lakh small unincorporated establishments in this group, employing 14.3 lakh people, and 67.2% ran without hired workers.

It’s one of the highest-earning small business groups. Average value added per business was ₹5,92,712 a year in urban areas in 2023-24. Solo professionals added ₹2,50,602 on average, while those with hired staff added ₹10,44,736. Average pay per hired worker in urban professional businesses was ₹1,87,936, including employer contributions.

Step 1: Build skills and credentials

Clients hire designers they trust to manage their money and their home. Build:

• Formal training: a degree or diploma in interior design from a recognised institute helps, though many successful designers start with shorter courses and experience.
• Technical skills: space planning, materials, lighting, furniture, joinery details and basic services (electrical, plumbing, HVAC coordination).
• Software: AutoCAD for drawings, SketchUp or similar for 3D, and a rendering tool for realistic visuals.
• Site experience: working for an established designer or contractor teaches you what clients never see in a course: how carpenters, electricians and vendors work, and what goes wrong.

Professional bodies such as the Institute of Indian Interior Designers (IIID) offer networking, events and credibility.

A note on titles: under the Architects Act, 1972, only people registered with the Council of Architecture can use the title "architect". Interior designers can offer design services freely, but should describe themselves as interior designers.

Step 2: Choose your business model

• Design only (consultancy): you provide concepts, drawings, 3D views, a bill of quantities and specifications, and the client hires contractors. Lower risk, lower revenue.
• Design and supervision: you design and supervise the contractors the client hires, checking quality and progress.
• Turnkey (design and build): you design and deliver the finished space, managing vendors and materials. Higher revenue, but you carry the risk of delays, cost overruns and quality issues, and need working capital.

Many designers start with design-only or supervision projects, then move into turnkey work as they build a reliable vendor team.

Step 3: Set up the business

• Structure: most designers start as sole proprietors. Partnerships and growing studios often choose an LLP for limited liability with lighter compliance than a company. Try Advanton’s business structure chooser, or read choosing a business structure in India.
• Registrations: shops and establishments registration for a studio, Udyam registration (free) and GST registration once turnover crosses the threshold or your business clients need it. See our GST registration guide.
• Workspace: start from home or a co-working space; a small studio with material samples helps clients decide once you’re established.
• Tools: a good laptop, software licences, a laser measure, material sample boards and a camera or good phone for project photos.

Step 4: Price your services

Common fee models in India include:

• A fixed design fee for a defined scope, such as a 2BHK apartment.
• A rate per square foot of carpet or built-up area.
• A percentage of the project cost, common for design and supervision, and for turnkey work.
• Hourly or daily rates for consultations and small jobs.

Whatever model you use, define exactly what’s included: number of design options, revisions, site visits, drawings and whether supervision is included. Extra revisions and visits should be charged separately.

For turnkey projects, separate your design fee from the execution cost in your quotes, and show your margin on materials and labour clearly.

Step 5: Contracts and payments

Disputes in interior projects usually come from unclear scope or payments. Your contract should cover:

• the scope of work, rooms and deliverables
• the fee and what it includes
• the timeline, with dependencies on the client (approvals, site access, payments)
• payment milestones, for example an advance on signing, then payments on design approval, on starting work, at key stages and on handover
• how changes (variations) are priced and approved
• who buys materials, and who’s responsible for defects
• warranty and after-sales support

Issue a proper invoice for each payment with Advanton’s free GST invoice generator.

Step 6: GST for interior designers

• Design services are generally taxed at 18% GST.
• Turnkey projects that combine design, materials and installation can be treated as works contracts, with their own GST treatment. Get advice from a chartered accountant on how to structure and invoice them.
• Business clients, such as offices, clinics, cafes and builders, can claim input tax credit on your GST, so they often prefer registered designers.
• Clients in other states: charge IGST instead of CGST and SGST. Our GST invoice guide explains how.

Step 7: Build a vendor network

Turnkey work depends on reliable partners: carpenters and modular kitchen and wardrobe manufacturers, false ceiling and painting contractors, electricians and plumbers, flooring and tile suppliers, and lighting, furniture and furnishing suppliers.

Test vendors on small jobs, agree rates and quality standards in writing, and pay them on time. A dependable team is your biggest competitive advantage.

A typical project, stage by stage

Most residential projects follow the same path. Setting expectations at each stage avoids most disputes.

1. First meeting and site visit: understand the client’s needs, budget, timeline and taste. Measure the site and photograph it.
2. Proposal and contract: scope, fee, timeline and payment milestones. Take an advance on signing.
3. Concept: mood boards, layout options and a rough budget. Agree one direction.
4. Design development: detailed layouts, 3D views, lighting and electrical plans, and material and finish selections. Limit revisions to what your contract allows.
5. Working drawings and bill of quantities: detailed drawings for carpenters and contractors, and a costed list of materials and work. For design-only projects, this is often the main deliverable.
6. Execution: site work in a sensible order (civil changes, electrical and plumbing, false ceiling, flooring, carpentry and modular work, painting, then fixtures and furnishings), with regular site visits and photos for the client.
7. Snagging and handover: a joint walk-through, a list of fixes, and final payment once they’re done.
8. After-sales: a warranty period for workmanship, and a request for a review and permission to photograph the space.

Step 8: Win clients

• Portfolio: photograph every finished project professionally, with before-and-after shots. Show your process, not just the final result.
• Instagram and Pinterest: interior design is visual, and many clients find designers there.
• Google Business Profile: with project photos, services and reviews.
• The India Business Directory: list your studio free so homeowners and businesses searching for interior designers in your city find you.
• Referrals and partnerships: builders, real estate brokers, architects and modular kitchen showrooms can send you clients. Happy clients are your best marketing.

Step 9: Grow into a studio

Hiring is how design businesses grow: a junior designer for drawings and 3D, a site supervisor, and later a project manager. The ASUSE figures show that professional businesses with staff generate several times the value of solo practices. Check the full cost of each hire with Advanton’s hiring cost calculator, and read running solo or hiring staff.

Common mistakes

• Unlimited revisions. Define the number in your contract.
• Starting work without an advance. Always take one, and stage payments to match work.
• Mixing design fee and material margins without telling the client. Transparency builds trust and referrals.
• Taking on too many turnkey projects without the working capital or team to deliver them.
• No photos of finished work. Every project is future marketing.
