How Should I Compare Interior Quotations?
Two interior quotations can look similar at first glance and still represent very different projects. The safest comparison is scope-to-scope, specification-to-specification and item-to-item — not simply the lowest total.
Never compare two quotations until the scope is comparable.
A quotation is only meaningful when you know exactly what each designer or execution company has priced.
One company may include a modular kitchen, full-height wardrobes, electrical modifications and installation, while another may quote only cabinetry and selected furniture. The second quotation can look cheaper without actually representing the same project.
Current Interior A to Z guidance similarly recommends comparing the exact scope, materials, hardware, furniture, execution, supervision, installation and exclusions rather than the headline amount. :contentReference[oaicite:0]{index=0}
The best starting point is therefore to create one common brief and send that same brief to every designer you are evaluating.
Use the same seven-step method for every quotation.
Freeze the brief
Give every designer the same property type, rooms, area, requirements, style and expected scope.
Compare the BOQ
Check quantities, measurements, specifications and prices item by item rather than relying on a lump sum.
Check materials
Compare board grade, thickness, laminate or other finish, hardware and product specifications.
Check services
Confirm design, drawings, site supervision, installation, project management and coordination responsibilities.
Find exclusions
Identify electrical, plumbing, civil, appliances, taxes, transportation and other items outside the quote.
Check commercial terms
Review payment milestones, change-order rules, timeline, warranty and handover conditions.
Start with the rooms and work included.
Before looking at materials or prices, make sure every quotation covers the same parts of the home.
Use this table before deciding which quotation is actually comparable.
Put the quotations side by side and record the actual specification instead of marking everything simply as “included”.
| Category | What to compare | Questions to ask | Why it matters |
|---|---|---|---|
| Project scope | Rooms, areas and work items | Are both quotations covering exactly the same work? | A smaller scope can make a quotation appear cheaper. |
| Measurements | Carpet area, running feet, square feet or item quantity | What measurement basis was used? | Different measurement methods can change the total substantially. |
| Kitchen | Cabinet structure, shutters, hardware, accessories, countertop | What exactly is included? | Kitchen specifications can vary significantly between quotes. |
| Wardrobes | Quantity, dimensions, internals and hardware | Are internal drawers and accessories included? | Two wardrobes with the same outside appearance may have different internals. |
| Furniture | Beds, sofas, dining, study units and other pieces | Which furniture is fixed and which is loose? | Furniture exclusions can create a large difference in total project cost. |
| Electrical | Wiring, points, switches, fixtures and installation | Are new points and fixtures included? | Electrical changes are frequently handled separately. |
| Installation | Delivery, assembly, fixing, levelling and finishing | Who installs and completes the work? | A material-only quotation is not equivalent to a turnkey execution scope. |
| Taxes | GST and other applicable charges | Is the quoted amount tax-inclusive? | Headline prices should be compared on the same tax basis. |
| Warranty | Product and workmanship coverage | What is covered and for how long? | Warranty terms affect the real commercial value of a proposal. |
| Exclusions | Appliances, civil, plumbing, painting, curtains and other work | What will I have to pay separately? | Exclusions explain many apparent price differences. |
“Premium material” is not a specification.
Ask every designer to state the actual material, grade, thickness, finish and application. This is particularly important for kitchen and wardrobe quotations.
Compare the specification, not the adjective
“Best quality”, “premium plywood” or “branded hardware” does not provide enough information for a fair comparison. Ask for the exact specification that appears in the BOQ or material schedule.
A detailed BOQ makes the quotation easier to understand.
A Bill of Quantities can break a large project into measurable items. That makes differences between two proposals much easier to identify.
What a useful BOQ can show
• Item or work description
• Quantity or measurement
• Material specification
• Finish
• Hardware
• Unit rate where applicable
• Total amount
• Installation or labour scope
Why lump-sum quotes are harder to compare
A single project total does not reveal whether one quotation includes more cabinetry, better hardware, additional furniture or more site work.
Look inside the storage, not just at the elevation.
Kitchen and wardrobe quotations can look very similar visually while differing considerably in their internal specifications.
| Item | Check in the quotation | Common comparison mistake |
|---|---|---|
| Kitchen carcass | Board, grade, thickness and construction | Assuming all plywood or boards have identical specifications. |
| Kitchen shutters | Material, finish, thickness and edge treatment | Comparing only colour and appearance. |
| Kitchen hardware | Hinges, runners, lifts and mechanisms | Accepting “branded hardware” without a product specification. |
| Kitchen accessories | Baskets, pull-outs, pantry and corner storage | Assuming accessories shown in the design are automatically included. |
| Wardrobe carcass | Board and internal configuration | Comparing wardrobe price without checking internal storage. |
| Wardrobe shutters | Finish, handles, profiles and hardware | Ignoring differences in shutter material and hardware. |
Find the costs that may sit outside the headline quotation.
Current interior-cost guidance highlights transportation, installation, electrical modifications, plumbing, demolition, painting repairs, hardware upgrades, appliances, loose furniture, curtains and taxes as items that should be checked explicitly. :contentReference[oaicite:1]{index=1}
The quotation is also a project agreement.
Price is only one part of the commercial relationship. Review how changes, payments, delays, warranty and handover are handled.
Be careful when a quotation is difficult to verify.
A very low headline price without a detailed scope may indicate omitted work or lower specifications.
“Premium”, “branded” or “best quality” should be replaced with actual material details.
Without measurable items, it is harder to understand what has actually been priced.
If you cannot identify what is outside the quotation, the final project cost may be difficult to predict.
Ask how additional work, upgrades and design changes will be documented and approved.
Know who is responsible for coordination, supervision, installation and quality checks.
Turn three quotations into one clear comparison.
Instead of relying on memory, create a simple comparison sheet and record the actual facts from every proposal.
| Category | Quotation A | Quotation B | Quotation C |
|---|---|---|---|
| Same rooms covered | Yes / No | Yes / No | Yes / No |
| Detailed BOQ | Yes / No | Yes / No | Yes / No |
| Board specification | Record actual specification | Record actual specification | Record actual specification |
| Hardware specification | Record actual specification | Record actual specification | Record actual specification |
| Kitchen scope | Record inclusions | Record inclusions | Record inclusions |
| Wardrobe scope | Record inclusions | Record inclusions | Record inclusions |
| Furniture | Record inclusions | Record inclusions | Record inclusions |
| Electrical / ceiling | Included / excluded | Included / excluded | Included / excluded |
| Installation | Included / excluded | Included / excluded | Included / excluded |
| Taxes | Included / extra | Included / extra | Included / extra |
| Warranty | Record terms | Record terms | Record terms |
| Exclusions | Record | Record | Record |
Ask each designer to revise the quotation if the scope is unclear.
A useful comparison is not about forcing every company into the same price. It is about understanding exactly what each company is proposing.
Clarify
Ask questions about missing quantities, specifications, rooms and services.
Standardise
Request comparable material and hardware specifications where you want a like-for-like comparison.
Document
Keep the final scope, approved materials, exclusions and commercial terms in writing.
Do not negotiate only from the total
If a quotation is higher, first identify why. It may include additional rooms, better hardware, more furniture, additional site work or a broader execution responsibility. If a quotation is lower, identify what has been reduced or excluded.

Comparing interior quotations
How should I compare interior quotations?
Compare interior quotations using the same project brief and check the scope, quantities, materials, hardware, furniture, electrical work, ceiling, installation, site supervision, taxes, warranty, payment milestones and exclusions. Do not compare only the final price.
Should I compare interior quotations by price per square foot?
Per-square-foot pricing can be useful as an initial reference, but it should not be the only comparison method. Confirm what the quoted rate includes and compare the actual BOQ, materials and execution scope.
What should an interior quotation include?
A detailed quotation should identify the rooms and work scope, quantities or measurements where applicable, materials, finishes, hardware, furniture, installation, labour, site responsibilities, exclusions, taxes, payment milestones and warranty terms.
What is a BOQ in interior design?
BOQ means Bill of Quantities. In an interior project it can break the scope into work items, quantities, specifications and costs, making the quotation easier to review and compare.
Why are two interior quotations so different?
Two quotations can differ because of material grades, hardware, finishes, quantities, furniture, kitchen and wardrobe scope, electrical work, civil work, installation, project management, taxes and exclusions.
Should appliances be included in an interior quotation?
Appliances may be included or excluded depending on the project. The quotation should clearly list appliances such as chimney, hob, oven, dishwasher and refrigerator if they are part of the scope.
How do I compare plywood and hardware in interior quotations?
Compare the exact board material, grade, applicable standard, thickness and application. For hardware, compare the manufacturer or product series, mechanism type, quantity, load rating where relevant and warranty.
What exclusions should I check in an interior quotation?
Check electrical modifications, plumbing, civil work, demolition, painting repairs, appliances, loose furniture, curtains, transportation, installation, taxes and any additional-work charges.
Should payment milestones be included in the quotation?
Yes. Payment stages should be documented along with the corresponding project milestones, scope, taxes and conditions so both parties understand when payments are due.
Compare the scope before you compare the price.
A clear quotation should make the materials, quantities, services, installation, exclusions and commercial terms understandable before the project begins.
