Credit Limit

A credit limit is the maximum amount of outstanding credit a business agrees to extend to a customer at any one time - acting as a cap on unpaid invoices before new orders must be paused, reviewed, or prepaid.

Why Credit Limits Matter in Practice

When a business supplies goods or services on credit, each unpaid invoice represents money the supplier has already spent - on materials, labour, or time - before receiving payment. A credit limit sets the point at which that exposure becomes too high relative to the risk the customer represents. Without a defined limit, a single customer can accumulate a large unpaid balance that, if they fail to pay, creates a cash flow problem disproportionate to the value of their account.

Credit limits are most common in B2B trade relationships: a supplier of materials, a promotional merchandise distributor shipping orders on account, or a contract furniture business sending staged deliveries before final invoice settlement. Any business that extends net-30 or net-60 payment terms to customers is, in effect, operating a credit facility - and each customer on those terms should have a limit, even an informal one.

How Credit Limits Are Set

The most practical method for SMBs is to base initial credit limits on a combination of: the customer's trading history (if any), reference checks or credit reports, and the expected order value over a rolling period. A common rule of thumb is that initial limits should not exceed the equivalent of one or two standard order cycles - enough to accommodate normal trading without creating undue exposure if payment slips.

For established customers, limits should be reviewed periodically and adjusted based on payment track record. A customer who consistently pays on time warrants a higher limit; one who regularly pays late or disputes invoices warrants a lower one - or a requirement to prepay.

A credit hold is the operational action that follows when a customer reaches or exceeds their limit. New orders are paused until outstanding invoices are paid down below the limit, or until the limit is formally reviewed and increased. Tracking customer balances against credit limits in real time - rather than checking manually at the point of a new order - is what makes credit limits practically enforceable for a business handling multiple accounts simultaneously.
