That’s one of the smartest questions to ask 👍 — because many designers in Delhi NCR quote a “base cost” but later add GST, transport, supervision charges as extras. This is where budgets often get derailed.

✅ Typical Extra Charges You Should Clarify

Table of Contents

1. GST (Goods & Services Tax)

Standard GST for interior services: 18%.
Some designers quote exclusive of GST (add later).
Always confirm: “Is this quote GST inclusive or exclusive?”

2. Transport & Delivery

Covers shifting materials from vendors to your site.
Typical: ₹10,000–₹30,000 (can be higher if multiple trips or heavy marble/stone).
Some turnkey firms include it, others bill separately.

3. Site Supervision / Project Management

Covers designer/project manager/site engineer visits.
Small studios: may charge ₹1,000–₹5,000 per visit if not included.
Larger firms: usually include supervision in turnkey package.
Premium firms: charge 5–10% of project value as project management fee.

💡 What to Ask Your Designer

Is GST included in this quote?
Is transport/delivery/installation included?
Are site visits and supervision included, or extra?
If supervision is chargeable, how many visits are included?
Can I get a breakup sheet (Base Cost + GST + Transport + Supervision)?

⚠️ Red Flags

Designer avoids giving breakup, just quotes “lump sum.”
GST suddenly added at the end.
Transport not included → you pay surprise bills later.
Supervision not included → you end up paying extra for every site visit.

✅ Pro Tip

When finalizing, ask for an “All Inclusive Quote” with line items:

Base project cost
GST %
Transport/logistics
Site supervision
Any exclusions (appliances, loose furniture, décor, etc.)

That way, there are no hidden surprises later.

👉 Do you want me to prepare a Hidden Charges Checklist (GST, transport, supervision, exclusions) that you can hand to your designer, so you know everything is covered in writing before you sign?
