Every business: 9 card nuggets
What suppliers can charge you, how they get coded, and the settlement that could change who takes your business card.
Grab it →
The code is the store's biggest line, not your purchase. A merchant's code reflects its main business by sales volume, and its processor sets it. Printer ink bought at a hardware store earns like hardware.
Same roof, different code. When a business inside another one has its own name, its own space and its own register, Visa requires it to carry its own code. The coffee bar inside the supermarket isn't grocery.
A card-reader app still gets you coded. Payment facilitators have to look at every business they sign up and give it the code that fits. A shop on a phone reader is coded by what it sells, not by the app.
A surcharge is credit only, and capped. Visa caps credit surcharges at 3% or what the merchant pays to accept the card, whichever is lower, and bans them on debit and prepaid cards. It has to sit on its own line on your receipt.
Mastercard still allows 4%, for now. Mastercard's US cap is 4% or the merchant's cost, whichever is lower. The pending settlement would cut it to 3%.
A real convenience fee is flat. Visa's rules say a convenience fee is one fixed amount, whatever you pay, for using an extra channel like phone or online. It can't be stacked on a surcharge or added to recurring payments.
Government can charge service fees. Most suppliers can't. Visa allows a separate service fee only for utilities, schools, courts, fines, tax payments and government services.
A dollar price can still carry a foreign transaction fee. If your card charges one, it can apply to a purchase from a merchant based abroad, even when you pay in US dollars. Check software and ad bills.
Your supplier may soon be allowed to turn down business cards. A pending Visa and Mastercard settlement would let merchants decline whole card categories, business cards included. The final approval hearing is set for November 16, 2026. Nothing has changed yet.
General information, not tax, legal or financial advice. Merchant codes are set by each merchant's processor, so your statement is the final word.

Selling to businesses: 2 nuggets
When your customers pay with business cards, the data you send changes what you pay.
Grab it →
Line-item data can cut your card cost. Visa's April 2026 rates show commercial cards with full line-item data at 1.75% plus 10 cents, against 2.70% plus 10 cents for a commercial card not present.
Your processor has to send it. Enhanced data only reaches Visa if you supply it and your processor passes it on.

Agencies: 3 Golden Nuggets
Media, creative and client money. What only an agency's statement shows.
Grab it →
Your clients see you as 7311. Visa lists ad agencies under Advertising Services, so client payments to you carry the advertising code.
Fronted media is your spend on the statement. Ad spend you pay for a client and bill back still lands on your card as yours. Agree on who carries it before the month closes. Example
Run the big media buy right after close. A buy charged the day after your statement closes isn't due until the next statement's due date. Your dates will differ. Example

The owner's operating rhythm
Weekly, monthly, twice a year. The money habits that keep surprises small.
Grab it →
Weekly: reconcile the cards. Ten minutes matching charges to receipts beats a lost Saturday at year end. Example
Monthly: run the statement check. The 10-minute statement check catches surcharges, foreign fees and miscoded suppliers. Example
Twice a year: re-read your card terms. Rewards categories and fees change. Your spending probably did too. Example
Before any big purchase: check your close date. A buy right after the statement closes buys you the most time. Example
A starting point, not legal, tax, HR or financial advice. State and local rules vary.

Day one: set up the money right
Onboarding your own business. Five moves that save years of cleanup.
Grab it →
Open the business bank account before the first invoice. Clean books start on day one. Commingled accounts are the most expensive habit to break. Example
Put every business expense on business accounts. One card per purpose makes categories and rewards easier. Example
Choose your statement close date on purpose. Line it up with when your biggest bills land. Example
Decide who can spend before anyone can. Write down who gets a card, the limit and who approves. Example
List your top suppliers and their codes. It's the map for every card decision after this. Example

Growing: cash, cards and rails
When revenue climbs, the payment rails matter as much as the price.
Grab it →
Use the card float on purpose. Time big buys right after your close date, and pay in full by the due date. Example
Send big payments the fast way when it matters. Same Day ACH handles up to $1 million per payment. RTP and FedNow allow up to $10 million, if your bank does.
Ask your bank about positive pay and ACH debit blocks. They stop the payments you didn't approve before they clear. Example
Review card limits before peak season. A declined card at the supply house is a lost day. Example
Re-map supplier codes when you add suppliers. New vendors mean new codes. Check the first statement after. Example

Playbook6 Example1 min
Scaling: cards, controls and approvals
More people spending means more ways for money to leak. Seven controls.
Grab it →
Separate approval from payment. The person who approves a vendor shouldn't be the one who pays it. Example
Set per-person limits and category blocks where your issuer allows. Spending controls work best before the first surprise. Example
Give each recurring vendor one card, with alerts. One place to look when a subscription changes. Example
Reconcile weekly once volume grows. Monthly reconciliations hide problems for 30 days. Example
Ask your issuer about corporate vs individual liability. It decides who owes the balance on an employee's card. Example
Check your own merchant code when your mix changes. Visa says a code follows the line with the most sales, so a shifted mix can mean a new code.
Train the team on bank-detail changes. Every change gets a phone call to a number you already had. Example
A starting point, not legal, tax, HR or financial advice. State and local rules vary.

5 questions for your supplier
Read them at the counter. Most reps have never been asked, and the answers are worth knowing.
Grab it →
"What category does your card terminal run under? Can you check the merchant code on your processor statement?"
"Do you add a surcharge for cards? Is it the same at every location and for every card type?"
"Is there a different price for paying by bank transfer, or for net terms?"
"Does your online ordering run through the same terminal as the counter?"
"Can my receipts show the item lines, not just a total?"
The questions are ours. Our words, not legal advice. The person on the other end may answer differently.

3 questions for your own processor
If you take cards, this is the call that tells you what your customers see.
Grab it →
"What merchant code is my account set up under? Is it the same for every location and website?"
"If I surcharge, is it credit only, under the cap, and on its own receipt line?"
"If the Visa and Mastercard settlement is approved, will you let me choose which card categories I accept?"
The questions are ours. Our words, not legal advice. The person on the other end may answer differently.

When a supplier adds a card fee
Four polite questions that tell you whether the fee follows the rules.
Grab it →
"Is that a surcharge or a convenience fee?"
"Is it on credit only? It can't apply to debit."
"Will it show as its own line on my receipt?"
"What's the price if I pay by ACH instead?"
This follows the card networks' US surcharge and convenience fee rules. State laws can be stricter. Our words, not legal advice. The person on the other end may answer differently.

For your bank, about ACH and wires
Two questions that tighten how money leaves your account.

For a client's accounts payable team
Three questions that get you paid faster and cheaper.
Grab it →
"Do you pay vendors by card, ACH or check, and which is fastest for you?"
"If it's a commercial card, do you need line-item detail on my invoices?"
"What are your payment terms, and who approves invoices?"
The questions are ours. Commercial card payments with line-item data can carry lower card costs. Our words, not legal advice. The person on the other end may answer differently.

One trip, five codes. Flights 4511, hotels 7011, cabs and rideshare 4121, rail 4112, rental cars 7512.
Big airlines carry their own code. Visa gives major airlines their own codes, from 3000 to 3350, and requires them on tickets, bag fees, upgrades and onboard buys.
If the travel agency charges you, it's 4722. Travel agencies and tour operators code as 4722, not as the airline or hotel.
A short-term rental can be a hotel, to Visa. Visa's lodging code, 7011, includes short-term rentals of under 30 days.
Car sharing counts as car rental. Visa includes car-sharing schemes in 7512, Automobile Rental Agency.
