GST input credit

If you're a GST-registered builder buying against tax invoices, the 18% GST shown above (₹2,72,164) is generally available as input tax credit (ITC), set off against your output GST — so your effective door cost is closer to the ex-GST subtotal of 15,12,020. Note: ITC on works contracts and immovable-property construction can be restricted (Section 17(5) blocked credits) depending on whether you're reselling/leasing or constructing for own use. Always confirm eligibility with your CA.

Optimise your project door spec

DesignAI helps you split the door schedule across types, sense-checks bulk rates for your city and suggests where to push the vendor for a deeper break.

Go deeper

Assumptions: supply-only base rates per standard 7×3 ft leaf, city-indexed; volume discount applied to leaf + frame only; hardware, fitting and 18% GST added on top. Discount tiers are indicative — real breaks depend on vendor, order mix, payment terms and freight. Verify every rate by city and vendor before ordering.
