Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How Credit Card Surcharges Reshape Small Business Cash Flow
Transcript
- Lucas: Luna, here's a number that might surprise you. The average small business in the US pays somewhere between 1.5 and 3.5 percent of every credit card transaction in processing fees. If that business does $500,000 in card sales a year — and most of them do — that's $7,500 to $17,500 straight out of working capital. Gone. Luna: That's a lot of cash. And it's not like they're choosing to eat that cost — customers expect to tap or swipe. Lucas: Right. And the structure of those fees is surprisingly opaque. The big chunk is the interchange fee — that's the percentage that goes to the card-issuing bank — and it varies by card type, by transaction size, even by whether the card is present or not. Rewards cards cost more. Corporate cards cost more. A Visa Signature card can carry an interchange rate of 2.5 percent plus ten cents, while a basic Visa debit might be 0.05 percent plus twenty-two cents. Luna: So the same coffee shop, same $5 latte — one customer pays with a Chase Sapphire Reserve, another with a debit card — the shopkeeper keeps a different amount each time. Lucas: Exactly. And until a few years ago, merchants couldn't do much about it. But in 2013, Visa and Mastercard settled a class-action lawsuit that opened the door for merchants to surcharge — that is, add a fee to the transaction to cover the processing cost. That settlement changed the game. Luna: I've seen that. A few stores in my neighborhood add a 3 percent 'card fee' at checkout. I'll admit, it makes me reach for cash sometimes. But is it actually legal everywhere? Lucas: Not everywhere. Ten states still ban surcharging entirely — California, New York, Texas, Florida are among them. And there are nuances. In some states, you can surcharge but you have to disclose it clearly at the point of entry. In others, you can only surcharge up to the actual cost of acceptance. So a blanket 3 percent might be illegal if your effective rate is 2.2 percent. Luna: So what's a business owner supposed to do? Eat the cost, pass it on, or just refuse cards? Lucas: A lot of them are choosing a fourth option: level-cost processing. That's where you negotiate a flat rate — say 2.3 percent — for all card types. It eliminates the surprise of high-interchange corporate cards and makes cash flow more predictable. But I want to talk about a specific case that shows the real impact on working capital. Luna: Let me guess — you've got a bakery in Portland? Lucas: How did you know? There's a bakery in Portland — call it 'Flour & Water' for the sake of the story — that was pulling about $400,000 a year in card sales. Their effective processing rate was around 3.2 percent because they had a lot of corporate card users — tech workers buying $12 sourdough loaves on their Amex. That's $12,800 in fees per year. They switched to a surcharge model where they added 3 percent at the register for all card payments. Luna: Did they lose customers? Lucas: A handful, but mostly at first. They put up a clear sign: 'A 3 percent surcharge applies to credit card transactions to cover processing fees. No surcharge for debit or cash.' Within three months, cash usage went from 20 percent of transactions to 35 percent. Their net margin improved by about 2 percentage points. That's $8,000 a year back in their pocket. Luna: And that $8,000 goes straight to working capital — it's not revenue, it's saved cost. That's meaningful for a small shop. Lucas: Exactly. And look — there's another piece of this that's less visible but even bigger for B2B businesses. When you sell to other businesses on net-30 or net-60 terms, and you accept credit card payments, the fee structure can actually eat your entire profit margin on that sale. Luna: Wait — say that again slowly. A 3 percent fee on a net-30 invoice could wipe out the profit? Lucas: Think about it. A typical wholesale margin in many industries is 15 to 25 percent. If you're selling $10,000 worth of goods at a 20 percent gross margin — so $2,000 in profit — and the customer pays with a corporate card costing you 3 percent, that's $300 in fees. Suddenly your margin drops from 20 percent to 17 percent. And if the customer pays late — say day 45 instead of day 30 — you've also lost the time value of that cash. Luna: So then some suppliers are starting to surcharge invoices, right? I've seen '2.9 percent surcharge for credit card payments' on a few vendor invoices recently. Lucas: That's becoming more common, especially in industries like wholesale distribution and manufacturing. And here's the interesting twist: the Card Act of 2009 and the Durbin Amendment capped debit interchange for large banks, but credit card interchange was never capped. So the fees have actually been rising. The average interchange rate for a Visa rewards card has increased about 20 basis points over the past five years. Luna: Twenty basis points doesn't sound like much, but on a $1 million in sales, that's $2,000. Lucas: Right. And it compounds. The other strategy I'm seeing more of is what's called 'interchange-plus' pricing. Instead of a bundled rate, the processor charges a fixed markup — say 0.25 percent plus ten cents — on top of the actual interchange cost. It's more transparent. You can see exactly where the money goes. Luna: So if your interchange cost is 1.8 percent, you pay 2.05 percent total. No hidden margin for the processor. Lucas: Exactly. And for a business that processes $500,000 a year, that can save $2,000 to $4,000 annually compared to a bundled rate. Now, I want to be clear — surcharging isn't right for every business. If you're in a competitive retail environment where every dollar matters, a surcharge might drive customers to the competitor across the street. But for B2B, where relationships are deeper, it's often an easier conversation. Luna: Yeah, you can frame it as a cost transparency thing. 'We're just passing along what Visa charges us.' That's harder to argue with. Lucas: And there's a regulatory angle that's worth flagging. The National Retail Federation has been pushing for legislation to cap credit card interchange fees — similar to what Europe did. In the EU, interchange is capped at 0.3 percent for credit cards and 0.2 percent for debit. That's a fraction of US rates. If something like that passed here, the whole calculus would shift. Luna: Imagine a world where the bakery in Portland pays $1,200 in fees instead of $12,800. That's real money for hiring or investing. Lucas: Exactly. But until that happens — if it ever does — the smartest move for a small business owner is to audit their processing statements. Most people never look at the line item. They just see 'processing fee' and accept it. Luna: And you're saying the audit alone can reveal thousands in savings? Lucas: Easily. I've seen businesses paying 3.5 percent effective rate on a mix that's mostly debit. They should be at 2 percent. That's $7,500 on $500,000 in sales. And it takes one phone call to their processor to renegotiate. Luna: Speaking of things that take one phone call — I want to mention something real quick.

Lucas: Yeah, and honestly — if one of these episodes saves you a few hundred bucks on processing fees, that's worth it. Anyway, back to the money. I want to talk about a tactic that's counterintuitive: offering a discount for paying by ACH or check. Luna: You mean like a 2 percent discount if they pay within 10 days? That's classic trade credit. Lucas: Right — the old 2/10 net-30. But applied to credit card payments. If a customer pays by credit card, you're losing 2.5 to 3 percent. If you offer them a 2 percent discount for paying by ACH, you come out ahead by 0.5 to 1 percent. And the customer gets a small benefit too. It's a win-win. Luna: So you're essentially sharing the processing savings with the customer. That's smart relationship management. Lucas: And it improves your cash conversion cycle because ACH settles in one to two days, while credit card settlements can take two to three days. Faster cash, lower fees. It's one of those rare moves that improves both the income statement and the balance sheet. Luna: But it requires some discipline to set up. You need to have the systems in place to track who's paying by what method and apply the discount automatically. Lucas: True. But most accounting software — QuickBooks, Xero, FreshBooks — can handle that now. They have payment gateways that let you set up surcharge rules or discount rules. It's not 2013 anymore. The technology has caught up. Luna: And I guess the last piece is the behavioral angle. If you surcharge, you're effectively training customers to use cheaper payment methods over time. That can lower your effective rate without you having to do anything else. Lucas: Exactly. One coffee shop I know put up a sign that says 'Cash and debit get a 10 percent discount' — which is actually just a surcharge on credit wrapped differently. Customers love it. They feel like they're getting a deal. And the shop saves money. Luna: Psychology matters. So to wrap up — the key takeaway for a small business owner today: pull your latest processing statement, calculate your effective rate, and see if you're leaving money on the table. Lucas: And if you're above 2.5 percent, you probably are. Call your processor, ask about interchange-plus, or consider a surcharge if it's legal in your state. Even a half-percent improvement on $500,000 is $2,500 a year. That's a meaningful chunk of working capital. Luna: And if you want to dig deeper, we'll put links to the state-by-state surcharge laws and a sample rate comparison sheet in the show notes. Lucas: Next episode, I want to talk about something that came up in listener mail — how to handle cash flow when you're growing too fast. It's a good problem to have, but it can kill you if you're not careful. Luna: Looking forward to it. For now, go check those statements. Lucas: Thanks for listening — we'll see you next time.
