the mutual understanding between the supplier/vendor
and the buyer.

large value.
@ terms and conditions are required for large
volumes.

from only one source.
@ when no acceptable quotations are received
from the other vendors.
4) DISCOUNTS:- They are cash concessions offered by

Purchasing from many many suppliers.
