Before You Sign: What to Check Before Hiring an Interior Designer in Mumbai

Hiring an interior designer is one of the most significant decisions you will make as a homeowner or business owner in Mumbai. You are not just hiring someone to pick colours and furniture — you are trusting a team with your home, your budget, your timeline, and your daily life for several months. Get it right and the experience is exciting, collaborative, and deeply rewarding. Get it wrong and it can become one of the most stressful and expensive experiences of your life.

At Tachi India, Wadala's most trusted interior design firm, we believe every client deserves to make an informed decision. So here is our honest, no-holds-barred guide to everything you should check, ask, and verify before you sign a contract with any interior design firm in Mumbai — and exactly how Tachi India measures up at every step.

1. Check Their Portfolio — Not Just the Best Projects

Every interior design firm has a curated portfolio of their finest work. That is not where the truth lives. Ask to see a range of projects — including smaller budgets, older projects, and spaces similar to yours in size and type. Ask what the brief was and how closely the final result matched it. A great firm is not one that only performs well on big-budget showcase projects. It is one that delivers consistently across all kinds of briefs.

At Tachi India, we are proud to show prospective clients our full body of work — from compact 1BHK apartments in Wadala to premium commercial fit-outs across central Mumbai. We share before-and-after documentation, client briefs, and the thinking behind every design decision. Our quality does not fluctuate based on the size of the budget.

2. Speak to Previous Clients Directly

Testimonials on a website are curated. Google reviews can be managed. The most reliable reference you can get is a direct conversation with a past client — ideally someone whose project was similar to yours. Ask the firm to connect you with two or three past clients. Ask whether the project was delivered on time, whether the final cost matched the original quote, whether communication was proactive, and whether they would hire the firm again.

Tachi India actively encourages prospective clients to speak with our past clients. We provide references without hesitation because we stand behind every project we deliver. If a firm is reluctant to provide references, that reluctance tells you everything you need to know.

3. Understand Exactly What the Quote Includes

One of the most common complaints about interior designers in Mumbai is that the final bill bears no resemblance to the original quote. Before you sign anything, insist on a fully itemised quotation that specifies every category of work: civil, electrical, carpentry, modular furniture, loose furniture, soft furnishings, lighting, décor, and labour. Ask specifically what is NOT included. Ask whether GST is included or will be added. Ask whether project management is charged separately.

At Tachi India, every client receives a fully itemised quotation before work begins. We sit with you and walk through it line by line so there are zero surprises from day one. This transparency is not just good practice — it is the foundation of a healthy client relationship.

4. Clarify Who Will Actually Work on Your Project

Many interior design firms in Mumbai sell you on the strength of their senior designer's personality and portfolio during the pitch, then hand your project to a junior team member with six months of experience. You meet the creative director twice and deal with a junior designer for the remaining five months of the project.

Ask who your primary point of contact will be from brief to handover. Ask who leads design and who manages the site. At Tachi India, we assign a dedicated senior designer and project manager to every client from the very first meeting. You always know who is accountable and have a direct line to them throughout.

5. Ask About Their Process for Managing Changes

Changes happen in every project. The question is not whether they will occur but how the firm handles them. A professional firm will have a formal change request process: the client requests a change, the firm assesses the cost and timeline impact, presents both to the client in writing, and proceeds only after written approval. An unprofessional firm will say yes to everything verbally and then present a large additional bill at the end.

At Tachi India, every change — no matter how small — is documented with a written cost and timeline impact communicated to the client before execution. You are always in complete control of your project and your budget.

6. Read the Contract Thoroughly Before Signing

A professional interior design contract should cover the full scope of work, the payment schedule tied to project milestones, the timeline with key dates, the change management process, warranty on materials and workmanship, and a dispute resolution mechanism. Read every clause. Do not sign anything with vague language around scope, timeline, or payment. Never accept verbal assurances about things that should be in writing.

Tachi India provides a comprehensive, client-friendly contract written in plain language. We encourage every client to read it carefully, ask questions, and fully understand what they are agreeing to before signing. A firm unwilling to put its commitments in writing is a firm that does not plan to keep them.

7. Verify Their Material and Vendor Relationships

Interior design firms often have commercial relationships with material vendors. Ask whether the firm marks up materials, whether you are free to source certain items independently, and whether the firm receives undisclosed referral commissions. At Tachi India, we are fully transparent about our vendor relationships and pricing model. Our priority is always to get you the best quality for your budget — and that sometimes means recommending a smaller local supplier over a big brand name.

8. Visit an Active Project Site

A portfolio shows you the finished product. An active project site shows you the process. Ask if you can visit a current project in progress. Is the site clean and organised? Are workers following safety practices? Does the project manager know the status of every element without having to check with someone else? A firm that manages its sites well will manage yours well too.

Tachi India welcomes prospective clients to visit our active project sites with prior notice and client permission. We are proud of how we run our operations and we have nothing to hide.

9. Trust Your Instincts in the First Meeting

The first meeting is as much about fit as it is about credentials. Did they listen more than they spoke? Did they ask about your life, your routines, and your preferences — or did they mostly talk about their own work? Did they treat your budget with respect, or immediately push you toward a higher spend? If you leave the first meeting feeling unheard or pressured, that feeling will not improve over a five-month project.

At Tachi India, our first meeting is always a listening session. We want to understand your world before we begin designing your space. Every great home starts with a great conversation.
