A Bangalore homeowner's checklist of questions, contract clauses, and red flags to check before paying any interior design advance.
A few months back, a homeowner on Sarjapur Road posted in a local Facebook group about her interior contractor. She'd paid him 3.5 lakh as a booking advance for her 3BHK, work started on schedule, then stalled for six weeks with no explanation, and then his number stopped going through altogether. If you spend any time in Bangalore homeowner WhatsApp groups, you'll find some version of this story on a loop. It isn't that interior design here is a uniquely risky trade. It's that most people sign their first interior contract without knowing what a normal one is even supposed to contain, and that gap is exactly where things go wrong. None of this is meant to scare you off hiring help. It's meant to help you spot the difference between a professional setup and a risky one before any money leaves your account.
Red flags to watch for before you sign anything
The biggest interior designer red flags show up long before the first coat of paint. If a designer or contractor won't put anything on paper and works entirely off WhatsApp quotes and verbal promises, that's the first thing to notice. A written agreement costs them nothing to produce if the business is legitimate.
Pressure to pay a large advance fast is another one. Lines like "this rate is only valid if you confirm today" or "I need 50% now to block your slot" are designed to get money moving before you've had time to check anything. A firm confident in its own work rarely needs to rush you.
Watch for the absence of a GST invoice or a registered business name on the quotation. A one-person operation billing you off a personal UPI ID or a WhatsApp number, with no firm name, no GSTIN, and no office address, is much harder to trace if something goes wrong later. Also be wary of a scope of work that just says "kitchen and wardrobes as discussed" instead of an itemized list with measurements, materials, and finishes. Vague scope is how disputes over "what was actually promised" begin.
Questions to ask an interior designer before hiring
Before you hire anyone, or hand over even a token amount, there's a set of questions to ask an interior designer before hiring that tends to separate serious professionals from people who'll disappear halfway through your project.
Ask to see two or three sites that are currently under construction, not just finished portfolio photos. Anyone can share nice pictures; an active site tells you how they actually manage a project mid-way. Ask for their GST number and registered firm name, and check the GSTIN yourself on the GST portal rather than taking it on faith.
Ask exactly which plywood brand and grade they'll use for your carcass, and get that written into the quote rather than left as a verbal assurance. Ask how the payment schedule is structured and what deliverable each payment is tied to. Ask who your single point of contact will be once the project starts, because a designer who hands you off to an unnamed "site team" with no one accountable is a common early complaint in Bangalore forums. Ask what warranty applies to workmanship versus what the plywood or hardware manufacturer separately covers, and ask what happens to your payment schedule if the project runs late.
What a proper interior design contract should include
A decent interior design contract checklist isn't complicated, but it does need to cover a few specific things, and most disputes trace back to one of these being missing or left vague.
Payment milestones should be tied to actual deliverables, not calendar dates. "30% on completion of carcass installation" protects you far more than "30% after 20 days," because the second version pays out whether or not the work is actually done. Material specifications need to be written into the contract itself, not just mentioned during a showroom visit; if you agreed on Century Ply or Greenply BWP-grade for wet areas, that brand and grade should appear on paper, along with the laminate brand and thickness and the hardware brand for hinges and channels.
The timeline should carry a real completion date along with a delay clause, something as simple as a small percentage deducted for every week past the agreed date, beyond a reasonable grace period. And the warranty terms matter more than people expect: workmanship warranty (usually a year, sometimes two) is separate from the plywood manufacturer's own warranty, which can run much longer depending on the grade. Finally, a good contract holds back a small retention amount, often 5 to 10% of the total value, paid out only after a final walkthrough and a punch-list of snags is cleared.
This is more or less how we structure every project at YellowDot Design Studio: milestone-linked payments, brand and grade written into the BOQ line by line, and a delay clause instead of a soft target date. If you're currently comparing two or three quotes, send them over and we'll walk you through what's missing before you sign anything, no strings attached.

How to check material quality once work starts
Paperwork protects you before the project starts. Once carpentry work is actually underway, you need a few practical ways to check what's going into your home matches what was quoted.
Start with the plywood. Ask the site team to show you an offcut and look at the cross-section, the exposed edge where the layers are visible. It should show uniform layers with no visible gaps, no crumbling core, and no odd filler blocks patched in. Genuine BWP and BWR grade ply usually carries an ISI mark stamped or printed on the edge along with the brand name; if the material on site has no markings at all, or the brand doesn't match your invoice, that's worth stopping and asking about immediately.
Cross-check the material delivery challan against your quotation. If you were quoted a specific plywood brand and grade, the delivery slip should show that same brand, not a generic "commercial ply" substitute. The same applies to hardware: brands like Hettich, Hafele, and Ebco stamp their names directly onto hinges, channels, and soft-close mechanisms, so a quick look at the fitting itself tells you whether it matches what you paid for or whether an unbranded lookalike has been swapped in.
Payment structure that actually protects you
This is where most of the damage happens when things go wrong, and it's also the easiest thing to get right if you set it up correctly from the start. As a general rule, never pay more than 10 to 20% as a token or booking advance, regardless of how good the discount sounds for paying more upfront.
A reasonable structure looks something like this: 10 to 20% at booking, 30% once materials are ordered and confirmed against the BOQ, 30% after carcass and carpentry work is installed on site, 20% after shutters, hardware, and finishing are fixed, and the final 10% released after a completed handover and snag-list walkthrough. This way, no single payment ever gets too far ahead of the actual work you can see in front of you. Pay through a bank transfer or cheque to the business's registered account rather than a personal UPI ID, since it gives you a documented trail if you ever need to prove what was paid and when. Whenever anyone frames a large upfront payment as the only way to "lock in" pricing, treat it as a prompt to slow down rather than speed up.
What to do if your designer or contractor stops responding
If calls go unanswered and messages sit on one tick for days, start by pulling together everything you have: the signed contract, the original quotation, payment receipts, WhatsApp conversations, and dated photos of the work at each stage. This record matters far more than it seems like it should in the moment, because it's what turns "he stopped answering" into a documented, provable timeline.
Send a written notice, over email if possible, describing the breach and giving a specific, reasonable deadline to resume work or respond. Interior fit-out work in Bangalore isn't regulated the way new real estate construction is under RERA, but that doesn't mean you're without options. Consumer protection law in India covers deficiency in service, and the district consumer disputes redressal commissions accept complaints through the government's e-Daakhil portal for exactly this kind of dispute. This is general awareness rather than legal advice, and for anything involving a significant sum, it's worth a short consultation with a lawyer who handles consumer cases before you file anything formally.
