What is a credit limit in business?

A credit limit is the cap a business sets on how much any single customer can owe at one time. When a customer reaches their limit, the seller typically stops shipping goods or starting new work until existing invoices are paid down. Credit limits are most common in wholesale, distribution, and professional services where large customers can quickly accumulate significant outstanding balances.

Setting credit limits requires balancing sales growth against collection risk. A limit that is too low frustrates good customers and blocks deals. A limit that is too high concentrates risk in accounts that may not be able to pay if something goes wrong. A useful starting framework sets limits based on the customer's creditworthiness, payment history, and the size of the exposure relative to the seller's own cash position.

Credit limits are most effective when enforced consistently and reviewed periodically. A customer whose limit was set when they were small may need adjustment as they grow — or a reduction if their payment history has deteriorated. Reviewing limits at least annually, and after any significant late payment, keeps the exposure aligned with reality.
