Trade credit is the oldest form of business financing on the planet, and it is still the most underused. Ask any seasoned controller how they fund inventory or supplies, and the answer is almost never "a loan." The answer is net terms. The supplier ships, you sell, and you pay the supplier 30, 60, or 90 days later out of the revenue the product generated. No application, no underwriting committee, just a credit line built into the way the business buys.
This guide covers what trade credit business owners should actually be using, how to build a reporting trade profile that lifts your bank credit ranking, and the one piece of math (early-pay discounts) that catches more owners off guard than anything else in B2B finance.
Net-30, 60, and 90 terms are de facto interest-free working capital
Here is the simplest way to think about trade credit: when a vendor extends net-30 terms, they are giving you a 30-day interest-free loan in the amount of the invoice. The Independent Finance Association and the Commercial Finance Association estimate that US B2B trade credit exposure runs around $5 trillion annually, which is larger than every business loan written by every bank in the country combined. It is the single biggest pool of working capital in the economy, and most small business owners barely touch it.
The mechanics are simple. You order $20,000 of inventory on net-60 terms. The supplier ships day one and invoices you. You have 60 days to pay. If your inventory turns in 35 days, you have already sold the product and collected the cash before the supplier's invoice is due. The float funds your entire purchase cycle at zero cost, which no bank product can match.
For comparison, a business line of credit at a competitive rate might cost you 12 to 18% APR. A working capital advance can land higher than that. Trade credit at $0 if paid on time beats both. The limit is that you cannot repurpose the money. A vendor giving you $50K of net-30 on industrial supply cannot fund payroll or rent. That is why most operators run trade credit alongside a bank line. For when each fits, see our guide on working capital vs. business line of credit.
Larger vendors run substantial credit programs once you are an established customer. Restaurant suppliers like Sysco and US Foods, industrial distributors like MSC and Fastenal, and trade specialists like Ferguson and Wesco routinely extend $50K to $500K credit lines to customers with a year of history. Those are real working capital lines, set up without a bank meeting.
Reporting trade lines build business credit faster than almost anything else
Here is the part most owners miss. Not all trade credit shows up on your business credit report. Vendors choose whether to report to Dun & Bradstreet, Experian Business, and Equifax Business, and most do not bother. The ones that do report, though, are the fastest legitimate way to build a strong commercial credit profile.
The classic starter list of net-30 reporters is well known inside the business credit community. Quill, Uline, Grainger, Home Depot Commercial, Lowe's Pro, and Office Depot ODP Business Solutions all report consistently. A second tier including Crown Office Supplies, Wise Business Supplies, and Granite Building Supply will often approve newer businesses with just an EIN and a DUNS number, no personal guarantee required. The trick is that you pay the same prices you would have paid anyway, you just buy the office supplies, cleaning products, or tools you already need on net-30 instead of putting them on a card.
The standard playbook to build a strong PAYDEX score in six to twelve months looks like this. First, register for a free DUNS number through Dun & Bradstreet, which takes about 30 days. Second, open three to five trade accounts with reporting vendors. Third, place small orders monthly and pay early or on time without exception. PAYDEX is a 0 to 100 score where 80 represents on-time payment and anything above 80 reflects early payment. Consistent activity across three to five reporters typically pushes a fresh DUNS profile from 0 to 80+ inside a year.
Why does that matter? A clean business credit profile is one of the things bank underwriters check before approving term loans and lines of credit. It is also the biggest separator between owners who can borrow in the business's name without a personal guarantee and owners who cannot. Our building business credit guide covers which bureaus to monitor, and the companion piece on business vs. personal credit scores explains how the two interact.
Take the early-pay discount almost every time
The single piece of trade credit math that owners get wrong most often is the early-pay discount. Vendors will sometimes offer terms written as "2/10 net 30," which means 2% off the invoice if paid by day 10, full amount due by day 30. On the surface that looks like a modest 2% saving for paying three weeks early. The actual annualized cost of skipping the discount is dramatically higher.
Run the math. By skipping the discount, you are effectively borrowing the discounted amount for the extra 20 days (day 10 to day 30) at a cost of 2%. Annualize that 2% across roughly 18 cycles per year and you land at an effective annual rate near 36%. That is more expensive than almost any bank product and competitive with the highest-cost merchant cash advances. Unless your cost of capital is genuinely north of 36%, take the discount.
The practical implication is that a 12% APR line of credit can be a profitable trade. Draw on the line to pay invoices by day 10, capture the 2% discount, and the spread between the 36% you avoid and the 12% you pay is pure margin. That is one of the cleanest uses of a line of credit.
For owners who want to fund this kind of strategy with a card stack, our complete guide to business credit cards covers which cards play well with early-pay strategies and which fall short on credit limits.

Frequently Asked Questions
Q. How do I get my first net-30 account if I have no business credit yet?
A. Start with vendors that approve new businesses on EIN and DUNS alone. Quill, Uline, and Crown Office Supplies are common first accounts because they extend small net-30 terms without a personal guarantee or extensive history. Place a small order, pay it on time, then add a second and third reporting vendor over the next 60 to 90 days.
Q. Does trade credit hurt my personal credit?
A. Generally no, as long as the vendor reports only to commercial bureaus and you pay on time. If you personally guarantee the account or default, it can roll over to personal credit through collections. Treat trade credit like real debt because it is. Late payments lead to fees of 1 to 3% and can result in vendor sales suspension, which is more disruptive to operations than most owners expect.
Q. Should I take vendor terms or use a business credit card?
A. Both, ideally. Vendor terms are interest-free and report to commercial bureaus, while a business card extends the float by another 25 to 50 days and earns rewards. The sequence we recommend most often is: pay the vendor invoice by day 10 with the business card to capture the early-pay discount, then pay the card balance in full at statement close. You get the discount, the float, and the rewards.
Q. What is a DUNS number and how do I get one?
A. A DUNS number is a unique nine-digit identifier issued by Dun & Bradstreet, and it is the foundation of your business credit profile. It is free to apply for and takes around 30 days to issue through the standard process. You need a DUNS number before any commercial bureau can track trade payment activity on your business.
Q. Can I get a bigger trade line from a major distributor as a newer business?
A. Sometimes, with a personal guarantee and tax returns or bank statements. Distributors like Ferguson, Wesco, MSC, and Fastenal will extend $25K to $100K credit lines to newer businesses if you provide financials and a PG. Once you have 12 to 24 months of clean payment history, those lines often expand into the hundreds of thousands without renewed underwriting.
Trade credit is the working capital tool sitting in plain sight on every supplier invoice, and most SMB owners use a small fraction of what is available to them. The owners who run a tight trade credit playbook (three to five reporting vendors, on-time payment, early-pay discounts captured every cycle) pay less for capital and qualify for cheaper bank products at the same time. If you want help structuring a line of credit that funds early-pay discounts, or working capital that bridges the gap when vendor terms run out, we can size the right product.
