Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How Overdue Receivables Spike Your Borrowing Costs
Transcript
- Lucas: Luna, here's a number that surprised me: the average small business with more than 30 percent of receivables past due pays about 2.3 percentage points more on their credit lines than one with clean books. Luna: That's a huge premium. And I'm guessing lenders aren't just guessing—they're looking at the aging report. Lucas: Exactly. A 2025 Fed study looked at loan-level data from community banks and found that the single best predictor of a small business's credit spread wasn't their debt to equity or even their personal credit score—it was the percentage of receivables over 90 days. Every 10 percent increase in that bucket added about 40 basis points to the rate. Luna: Forty basis points per ten percent? So if you've got forty percent of invoices sitting past ninety days, you're looking at 160 basis points extra on top of whatever base rate you'd get. Lucas: That's right. And that's before any loan covenants that might trigger. Some banks write in a receivables-aging covenant—if your over-90-day bucket exceeds, say, 20 percent of total AR, the bank can raise your rate by another 50 to 100 basis points on the spot, or even demand immediate repayment. Luna: So the same late-paying customer who's costing you time and potential write-offs is also making your borrowing more expensive. That's a double hit. Lucas: It is. And it's invisible to a lot of business owners because they don't connect their credit line renewal to their AR aging. They think the bank is looking at their cash flow statement or their tax returns. And those matter. But the aging report is a forward-looking signal of collection risk. Luna: And banks hate uncertainty. If they see a growing pool of old receivables, they assume worse is coming. Lucas: Right. So the fix isn't just about cash flow—it's about your cost of capital. One of the most direct tools is to offer a prompt payment discount. A classic 2/10 net 30—two percent off if paid within ten days, full amount due in thirty. We've talked about that before, but here's the angle I hadn't fully appreciated: a well-run discount program can shrink your over-90-day bucket to under 5 percent. Luna: And that sub-5 percent number is a signal to the lender that you've got control over collections. That can directly lead to a lower rate. Lucas: Exactly. A business owner I spoke with runs a wholesale distribution company. He implemented 2/10 net 30 about eighteen months ago. His over-90-day AR went from 22 percent to 4 percent. When he renewed his line of credit last quarter, his bank shaved 75 basis points off the rate. That's real money on a $500,000 line. Luna: That's $3,750 a year in interest savings just from offering a discount. And you'd have to calculate whether the discount costs more than that—but often the net effect is positive because you get paid faster and write off fewer receivables. Lucas: There is a point where this kind of work intersects with keeping the show going. If these conversations have moved your work forward in some small way, a couple of dollars a month is genuinely what keeps these going—buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it really does help. And we keep it ad-free because of that. Lucas: Alright, back to the mechanics. The other angle I want to highlight is that you can use your aging report proactively when negotiating with your lender. Luna: Bring it to the meeting, show them the trend line. Lucas: Exactly. If you can show that your over-90-day bucket has been declining for six quarters, you're making a case that your risk profile is improving even if your revenue is flat. That's a data-driven argument for a lower spread. Luna: And if you're applying for a new loan, you can present your aging report as part of your credit package. Some lenders might even offer a rate break if you commit to maintaining under 10 percent in the over-90 bucket. Lucas: Yes. There are banks now that explicitly price receivables quality into their small business loan pricing models. They'll ask for your AR aging as part of the application. If you don't have a clean one, you're leaving money on the table. Luna: What about using something like supply chain financing or factoring? We've covered those before—but do they affect borrowing costs? Lucas: They can, indirectly. If you factor your receivables, you're essentially selling them at a discount, which removes them from your balance sheet. Your aging report might look cleaner, but the cost of factoring can be high—often 1 to 3 percent of invoice value. And lenders may see factoring as a sign of cash stress, which could counteract the benefit. Luna: So it's not a straightforward fix. The cleaner path is to improve your own collections process. Lucas: Right. And it's not just about discounts. Some businesses use automated reminder systems, dunning emails that escalate, or even third-party collection agencies for the worst offenders. But the key metric to watch is your 'receivables turnover ratio'—how many times a year you collect your average receivables. Luna: Higher turnover means faster collection, which should lower your borrowing costs. Lucas: Exactly. If your turnover ratio improves from 6 to 8, that's a 33 percent improvement in collection speed. That directly reduces the risk premium a lender assigns. Luna: And we should mention that this applies to lines of credit, term loans, even equipment financing. Lenders look at overall working capital health. Lucas: Yes. The broader point is: your receivables management isn't just an operational concern—it's a financial strategy. Every day you shave off your average collection period is a small step toward lower cost of capital. Luna: So what's the one takeaway for a business owner listening? If you have a credit line or are planning to apply for one, run your current aging report. If your over-90-day bucket is above 10 percent, make a plan to bring it down. It could save you thousands a year. Lucas: And if that plan includes offering a 2/10 net 30 discount, run the numbers first. But the risk of higher borrowing costs is a powerful motivator to get those overdue invoices collected. Luna: I think that's a strong note to end on. Next time we could talk about how aging reports differ by industry—construction vs retail vs services. Lucas: That's a good idea. Some sectors have notoriously long payment cycles, and the lender expectations adjust accordingly. We'll dig into that.
