In manufacturing, usance means inputs.
It is used in usance bills.
Usance differs from country to country.
Usance usually applies to items or goods purchased on credit.
In medieval banking, usance denoted the period of time, set by custom, before a bill of exchange could be redeemed at its destination.
Usance may also mean the interest that will be charged on the person who has borrowed some amount of money.
I am advised that a maximum usance of 90 days is adequate for most cases; longer periods are exceptionally allowed if the circumstances justify.
