Interior design agreement — what to check before signing

The contract is the only thing standing between you and a project that drifts in scope, cost and time. Here are the 10 clauses every Chennai interior agreement must contain — and the ones vendors hope you won't ask for.

Quick answer

A solid interior design contract must include: an itemised scope referencing the BOQ, named materials and brands with grades, a milestone-linked payment schedule, a fixed timeline with a delay-penalty clause, a change-order process, a written warranty, and a final retention held until snag clearance. WhatsApp messages and verbal promises are not a substitute for a signed agreement.

Why a verbal agreement isn't enough

Most interior disputes in Chennai share one root cause: nothing was written down. Scope, materials, timeline and warranty all lived in WhatsApp messages and conversation — so when things drifted, there was nothing to enforce.

A proper contract isn't about distrust. It's about both sides agreeing precisely on the same thing, so there's no room for "that wasn't included" later.

The 10 clauses your contract must have

  1. Itemised scope — references the full BOQ; every room and unit listed.
  2. Materials & brands — plywood grade (marine BWP IS:710), hardware brand, finishes — named exactly.
  3. Payment schedule — milestone-linked, with each milestone defined and its amount.
  4. Timeline — a fixed completion date, not "around two months".
  5. Delay penalty — a per-day amount for delay beyond an agreed date.
  6. Change-order process — any scope change needs written approval and a priced addendum before work proceeds.
  7. Warranty — duration and exactly what's covered (workmanship, hardware).
  8. Final retention — 10–15% held until snag-list clearance.
  9. Material verification — your right to inspect material on site and receive retailer invoices.
  10. Exit / dispute terms — what happens if either side needs to end the contract.

Clauses vendors hope you skip

Watch for what's missing. A weak contract is often weak by omission. The clauses most often left out — because they protect you, not the vendor — are:

If any of these is missing, ask for it to be added. A fair vendor will agree.

Before you sign — a final checklist

  1. The itemised BOQ is attached to or referenced by the contract.
  2. Every material grade and brand is named — no vague terms.
  3. The payment schedule is milestone-linked, advance ≤ 10–15%.
  4. There's a fixed date and a delay-penalty clause.
  5. The warranty duration and coverage are in writing.
  6. A 10–15% retention is held until snag clearance.
  7. Both parties sign every page; you keep an original copy.
Tip: Read every line yourself. If a clause is unclear, ask for it to be reworded before signing — never after.

The Homeli contract

Every Homeli project runs on a written contract built around all ten clauses above. The itemised quote you approve becomes the contract — so scope can't drift. Materials and brands are named exactly. Payment is milestone-linked with a 10% booking advance. The timeline carries a ₹1,000/day penalty beyond day 70. Any change needs your written approval and a priced addendum before work proceeds. The warranty is written, and a final retention is held until you've cleared the snag list.

Note: This guide is general information, not legal advice. For a high-value project, having an advocate review your contract is always worthwhile.

Frequently asked

Should I sign a contract with an interior designer in Chennai?
Always. A written contract that references your itemised quote is your only enforceable protection. It should name materials and brands with grades, set a milestone-linked payment schedule, fix a timeline with a delay-penalty clause, define a change-order process, and state the warranty and final retention. Verbal promises and WhatsApp messages are not a practical substitute.
What should an interior design agreement include?
Ten essentials: an itemised scope referencing the BOQ, named materials and brands with grades, a milestone-linked payment schedule, a fixed timeline, a delay-penalty clause, a change-order process requiring written approval, a written warranty, a 10–15% final retention held until snag clearance, your right to verify materials and receive invoices, and clear exit/dispute terms.
What clauses do interior vendors often leave out of contracts?
The clauses most often omitted are the ones that protect the homeowner: the delay-penalty clause, named material grades (e.g. "marine BWP IS:710" rather than just "plywood"), the change-order process, the final retention, and the material-invoice handover. A weak contract is often weak by omission — if any of these is missing, ask for it to be added before signing.
What is a change-order clause and why does it matter?
A change-order clause requires that any change to the agreed scope — adding a unit, changing a material — be approved by you in writing, with a priced addendum, before that work proceeds. Without it, "extras" get added and charged at the vendor's discretion, and your final bill drifts well beyond the original quote. It is one of the most important protective clauses.
Is a WhatsApp agreement with an interior designer legally valid?
WhatsApp messages can serve as supporting evidence, but they are a poor substitute for a proper signed contract. Scope, materials, payment milestones, timeline, penalty and warranty scattered across chat messages are difficult to enforce. Always have a single, signed written agreement that consolidates everything, with the itemised quote attached or referenced.
Should I get a lawyer to review my interior contract?
For a standard project, carefully reading every clause yourself against a checklist is often enough — ensure scope, materials, payment, timeline, penalty, warranty and retention are all clearly stated. For a high-value project, having an advocate review the contract is worthwhile. General guides like this one are informational, not legal advice specific to your situation.
