In short
An interior designer's invoice shows the project and site address, the stage billed (concept, design development, execution or handover), design fees separately from materials and labour, HSN codes for goods supplied and SAC codes for services, GST on each line at its own rate (design services are usually 18%), advances received and the balance due. Splitting lines this way avoids disputes and keeps each GST rate right.

Frequently asked questions
Can design fees and materials be on one invoice?
Yes, as separate lines with their own HSN or SAC code and GST rate. If you take full responsibility for design and execution as one job, it may be a works contract instead; ask your CA.
What GST rate do interior designers charge?
Design services are usually taxed at 18% once you're registered. Goods you supply carry their own rates, often 18% for furniture and fittings.
How should I bill stage payments?
Issue an invoice at each agreed stage, quoting the stage and the total contract value, and take the earlier advance off the balance.
