Vetting Shippers: Credit Checks Before You Book a Load

As a freight broker, you sit in the middle of every transaction. The shipper pays you, and you pay the carrier. That arrangement is what makes brokerage work—but it also carries a risk that catches new brokers off guard: you owe the carrier whether or not the shipper ever pays you.

That single fact is why vetting a shipper's credit is one of the most important things you can do before booking a load. This guide covers why shipper credit matters, how payment timing affects your cash flow, where brokers find credit information, and what to do when a customer starts paying slow.

Why Shipper Credit Matters

When you book a load, you're extending credit. You arrange transportation, the carrier hauls the freight, and you invoice the shipper—usually with payment terms of 30, 45, or even 60 days. During that gap, you are on the hook.

Here's the uncomfortable reality: carriers expect to be paid, often within 30 days or less, and many use factoring companies that will come after you directly. If your shipper goes bankrupt, disputes the invoice, or simply refuses to pay, you still owe the carrier. The margin on a single load is thin. One unpaid invoice can wipe out the profit from a dozen good loads.

This is why experienced brokers treat every new shipper as a credit decision, not just a sales opportunity. Booking freight for a customer who can't or won't pay isn't revenue—it's a liability.

How Days-to-Pay Affects Cash Flow

Even shippers who pay in full can hurt you if they pay slowly. Days-to-pay—the average number of days a customer takes to settle an invoice—directly determines how much working capital you need.

Consider what happens between booking and collecting:

• You book a load and the carrier delivers.
• The carrier invoices you and expects payment in 15 to 30 days.
• You invoice the shipper on 45-day terms.
• You pay the carrier weeks before the shipper pays you.

That gap is a hole you have to fund out of your own pocket or a line of credit. The longer a shipper's days-to-pay, the bigger the hole. A customer who promises 30-day terms but consistently pays in 60 is effectively borrowing from you—interest free—and starving your cash flow in the process.

When you evaluate a shipper, don't just ask whether they pay. Ask how fast. A slow payer with a strong balance sheet is still a cash-flow problem for a growing brokerage.

Where Brokers Find Credit Information

You don't have to guess. Several sources give brokers real data on how a shipper handles its bills.

Industry Credit Bureaus

Freight-specific credit services aggregate payment behavior reported by other brokers and carriers. Common sources include:

• DAT — offers credit scores and days-to-pay data on brokers and shippers, drawn from its large network of load-board users.
• Ansonia Credit Data — a transportation-focused bureau that reports days-to-pay and credit limits based on trade experiences from other carriers and brokers.
• General business credit reports — services like Dun & Bradstreet, Experian Business, and Equifax Business provide broader financial health data, liens, judgments, and bankruptcy history.

Direct References and Public Records

Beyond the bureaus, do some homework of your own:

• Ask the shipper for trade references and actually call them.
• Check for tax liens, lawsuits, or bankruptcy filings in public records.
• Look at how long the company has been in business and whether it has a stable physical presence.

No single source tells the whole story. The best decisions come from combining an industry credit score, a general business report, and a couple of live reference calls.

Setting Per-Customer Credit Limits

Once you've reviewed a shipper's credit, translate what you learned into a hard number: a credit limit. This is the maximum amount of unpaid, outstanding freight you're willing to carry for that customer at any one time.

A simple approach:

1. Start conservative. Give new shippers a modest limit until they establish a payment history with you.
2. Tie the limit to the credit data. A strong score and fast days-to-pay justify a higher limit; a weak or thin file justifies a lower one.
3. Track outstanding exposure in real time. Before booking a new load, check whether it would push the customer over their limit.
4. Raise limits with proven history. As a shipper pays reliably, increase the limit gradually.

A credit limit isn't a punishment—it's a guardrail. It keeps one customer's problems from taking down your business, and it gives your team a clear rule instead of a case-by-case gut call under booking pressure.

Watching Concentration Risk

Even a great-paying shipper can be dangerous if you rely on them too heavily. Concentration risk is the exposure that comes from having too much of your revenue tied to a single customer.

If one shipper accounts for 40% of your loads and they suddenly slow their payments, cut volume, or fold, your entire brokerage feels it immediately. Diversification protects you:

• Track what percentage of your monthly revenue each customer represents.
• Set an internal ceiling—many brokers get uncomfortable when a single shipper exceeds 15 to 20% of revenue.
• Actively build new customer relationships before you become dependent on any one account.

Concentration risk and credit risk compound each other. A large credit limit for your biggest customer is exactly the situation that can sink you if that customer stops paying.

What to Do When a Shipper Pays Slow

Sooner or later, a customer who looked fine on paper starts stretching their terms. Catching it early is what separates a minor annoyance from a serious loss.

When days-to-pay starts creeping up:

1. Follow up immediately. Don't wait for an invoice to age 60 days. A friendly reminder at 35 days signals that you're watching.
2. Understand the cause. Is it a paperwork dispute, a temporary cash crunch, or a pattern of delay? The response differs for each.
3. Freeze new bookings if needed. If a shipper is over their limit or badly past due, stop booking new freight until they catch up. Adding loads only deepens your exposure.
4. Tighten or reduce their credit limit. Slow payment is new information. Adjust the limit to reflect it.
5. Escalate formally. If reminders don't work, move to written demand, then collections. Document everything.

The goal is never to be adversarial for its own sake. It's to protect the money you've already committed to your carriers. Every day an invoice ages, the risk of never collecting it grows.

The Bottom Line

Vetting a shipper's credit before you book isn't bureaucracy—it's survival. You are the one who pays the carrier no matter what, so you are the one who has to know whether the money is going to come back.

Check the credit data, watch days-to-pay, set a limit for every customer, avoid leaning too hard on any single account, and act the moment payments slow down. Do that consistently, and you turn credit risk from the thing that quietly kills brokerages into a routine part of running a healthy one.
