Credit limit less outstanding balance per trade account. An account with little headroom whose purchases flattened, or whose orders were held for credit, is constrained by credit rather than demand. Good payers get a limit review; slow payers get a collections conversation.
Credit control sees the limit; sales sees the flat purchases. The join shows a customer who wants to buy more.
Not unlimited. Excluded and counted.
Credit limit minus outstanding balance, as a share of the limit, per account, read beside payment record and the recent purchase trend.
A contractor with a $50,000 limit has a balance of $48,600 and has paid to terms for three years. Purchases stopped mid-month for the third month running. It is buying elsewhere from the 20th.
Sales sees a quiet account and credit control sees a full limit, in different files. Nobody joins them.
