How to Run a Business Credit Check on a Customer Before You Extend Terms

To run a business credit check on a customer, pull a commercial credit report from Dun and Bradstreet, Experian Business or Equifax Business using the company's legal name and address, review its credit score, payment history and any liens or judgments, and combine that with a completed credit application, bank and trade references, and your own read of their financials. Then set a credit limit and terms that match the risk. For a small order you might skip straight to references; for a large one, check all of it before you ship a dollar of product on credit.

Selling on terms is lending. The moment you deliver goods and agree to be paid in 30 days, you have made your customer an unsecured loan, usually at zero interest, on nothing but trust. A credit check is how you decide whether that trust is warranted and how much of it to extend. It is the cheapest bad debt you will ever avoid, because the money you do not lend to a company that was never going to pay is money you never have to chase.

How do you run a credit check on a business?

There are five sources of signal, and how many you use scales with how much credit is at stake.

1. A completed credit application. Before anything else, have the customer fill one out. It gives you their exact legal entity name, address, tax ID, principals, bank details and trade references, and it establishes in writing that they agreed to your terms. Everything else builds on getting the legal name right, because a report on the wrong entity is worthless.
2. A commercial credit report. Pull a report from one of the three main business bureaus (details below). This is the core of the check: a score, a credit limit recommendation, payment history, public records and company background.
3. Trade references. Call two or three suppliers the customer already buys from on terms. Ask how long they have sold to them, the high credit extended, current balance, and whether they pay on time. Suppliers are usually candid, and a real trade reference often tells you more than a score.
4. A bank reference. The customer's bank can confirm the account is in good standing and give a general sense of average balances. It will not share specifics without authorization, but it confirms the business is real and banked.
5. Their financials, when the deal is big enough. For a large credit line, ask for recent financial statements. You are looking at liquidity, whether they are profitable, and how much debt they already carry. An independent read on the numbers, and on the terms buried in the underlying contract of a large deal, tells you whether the request is proportional to the size of the business.

Which business credit bureaus should you use?

The three major commercial bureaus each score companies differently. You do not need all three for a routine check, but knowing what each one measures helps you read the report.

Higher is better on all three, but the number is a starting point, not a verdict. A thin file (a young company with little credit history) is not the same as a bad file, and a strong score on a company that just took on heavy debt can lag reality by months. Read the payment trend and the public records, not just the headline score.

What are you actually looking for in the report?

Skip past the score for a moment and look at four things that predict whether you get paid:

• Payment history trend. Are they paying suppliers slower this quarter than last? A rising average days-to-pay is an early warning that cash is getting tight, well before a score moves.
• Liens, judgments and collections. Tax liens, court judgments and accounts already in collections are the clearest red flags. A company that is not paying the government or losing lawsuits over unpaid bills will not prioritize you.
• Time in business and size. A company operating for ten years with steady revenue is a different risk from one incorporated last spring. Match the credit line to the track record.
• Consistency across sources. If the score is fine but two trade references say they stretch payments to 60 days, believe the references. Behavior beats the model.

How do you turn the check into a credit limit?

A credit check is only useful if it ends in a decision. Translate what you found into three levers: whether to extend credit at all, how much, and on what terms. A common approach is to start conservative and let good behavior earn a higher limit. Extend a modest line, require a deposit or shorter terms on the first few orders, and raise the limit once the customer has paid on time a few times. For a marginal applicant, you can still do business: ask for payment in advance, a partial deposit, or a personal guarantee from an owner.

Whatever you decide, write it down in a credit policy so the same rules apply to every customer and the decision does not depend on who took the order. Our guide on how to set a credit policy covers the limits, terms and approval steps to define once, and a good credit management software keeps those limits and the customer's live payment behavior in one place so the check does not end the day you approve them.

How often should you re-check existing customers?

Credit risk is not static, and the customer most likely to burn you is often one you approved years ago and never looked at again. Re-check your larger accounts at least annually, and immediately if you see warning signs: payments slowing down, a request to sharply increase their limit, partial payments, or an industry-wide downturn hitting their sector. The behavior you can watch for free, on your own ledger, is the best monitor you have. A customer whose average days-to-pay is creeping up is telling you something, which is why keeping an eye on days sales outstanding per account matters as much as the original check. If a good account starts slipping, tighten terms before the balance gets large, not after.

The bottom line

Running a business credit check means pulling a commercial credit report, reading the payment trend and public records rather than just the score, confirming it against trade and bank references and a signed credit application, and asking for financials when the line is large. Then you convert what you learned into a credit limit and terms sized to the risk, and you re-check as the relationship grows. It takes an hour and it is the single most effective way to prevent bad debt, because the debt you never extend is the debt you never write off. When customers do pass the check and buy on terms, the follow-up still has to happen, and accounts receivable automation software makes sure every one of those approved invoices actually gets collected on time.
