Udaipur and its surrounding belt move an enormous amount of stone, and almost all of it is sold on quotations assembled by hand. An enquiry arrives in English from a buyer who may be in the Netherlands, Vietnam or the Gulf, specifying grades, finishes, thicknesses and a port.
Producing the quote means walking several rooms. Someone checks what is actually in the yard. Someone else looks up the current slab rate. Someone works out packing, inland haulage, freight to the named port, insurance and the applicable duty drawback. Someone writes the email. Three days, sometimes five.
The numbers that moved.

A decimal error in a CIF quote on a 20-tonne order is a disaster that cannot be recalled.
