Stone and aggregate from nearby quarries
The quarrying around Rohtas means aggregate and stone are local rather than brought in, which changes the rate structure and the units. CFT, tractor loads and tipper measures vary by convention, and holding the conversion on the item is what keeps your quoting consistent and your stock figure meaningful.
A highway location supplies both ways
Being on the main route means buyers arrive from several districts and loads leave in several directions. Agreed rates held per party mean the right price appears whoever is billing, and the delivery record with vehicle and receiver settles the question that comes weeks later.
Royalty and freight on their own lines
The delivered price of aggregate is material, royalty or ghat charge, and the run to the site. Folding all three into one rate makes your quote look expensive against a supplier who breaks them out, and hides where your margin actually is.
Credit across a rural catchment
Buyers spread across the district settle at different paces tied to their own income. Ageing rather than a total shows where the risk sits, and a statement on the first of the month settles accounts before they accumulate into something awkward.
