Possession, not intention
Interiors buying is triggered by handover. Once keys arrive, a decision that has been drifting for months usually resolves within weeks, because the family is paying rent and an EMI at the same time. Capturing possession date at first contact turns an undifferentiated list into a queue with a natural order.
Area and scope, captured as numbers
Carpet area gives a defensible project value before a single drawing exists, and scope tells you whether the work is a full fit-out, a part scope or a single modular package. Together they decide whether the enquiry deserves a senior designer or a standard quotation, and they do it more reliably than a stated budget.
Money and access
Two behaviours separate real projects from free-design shopping: paying a design or booking fee, and allowing a site measurement. Both cost the client something, which is precisely why they predict. A client who has done neither, however enthusiastic on the phone, is usually still comparing studios.
