How Lead Desk works for building materials
An enquiry arrives from IndiaMART or JustDial.
Vijaya calls and notes what the customer needs.
You approve the quote before it goes out.
Vijaya follows up on the delivery.
Every enquiry needs maths, and every delivery needs a plan
- Area to quantity, wastage and transport take time, so quotes go out late.
- Deliveries go in trips, and a missed trip means an angry site.
- Contractors pay late, and chasing them takes your evenings.

Pieces per sq ft and the truck load are typical figures, not your seller's. Your exact quote can differ.
Questions, answered calmly
Does the calculator give a price?
It gives the quantity and the trips. If you type a price per sq ft, it shows the material amount. A seller's exact quote can differ.
Can it handle transport and delivery trips?
Yes. You set the transport rule once. Quotes include it, and deliveries are planned in trips.
Will it chase contractors by itself?
No. It drafts a polite reminder, and you approve it. Anything about money always waits for you.
