Is surcharging the right tool for B2B?
Published network caps are often 2.4% on credit. Debit is often outside that framework. Some markets prohibit surcharging; confirm with counsel before advising a named merchant. Legality is not the same as it being the right tool on an $8,000–$47,000 invoice.
B2B is not exempt from the customer noticing. A purchasing card is 30–55 days of issuer float plus a rebate the buyer’s treasury already modelled. Add 2.4% to the invoice and you have given them a project: move the account to EFT. They will complete that project on the large tickets first.
The processing charge difference, in dollars
Invoice × 2.4%. $800 → $19. $8,000 → $192. $47,000 → $1,128. Those tickets are illustrative, not a sample. The $19 does not move a buyer. The $1,128 does, immediately and permanently. Distributors do not live on $800 tickets. That is why a surcharge that “works” in retail fails in wholesale.
Interchange optimization does not add a line to the invoice. The published reduction on qualifying commercial volume is 0.45–1.5%. The customer’s cost does not change. You settle in 48 hours. The processing charge difference versus a 2.85% effective rate is the entire product. We verify it against the statement at no cost.
What happens to volume over twelve months
A modelled assumption, labelled illustrative, is that 30–50% of surcharged volume migrates to EFT within 12 months. It is not an observed Novaline panel. We still use it because the direction is obvious to anyone who has tried to surcharge a house account. You keep the small-ticket tail. You lose the tickets that made card acceptance valuable once the take-rate was honest.
Optimization keeps the volume and, if the rate is honest, can grow it. Payment links on every invoice, a portal showing open balances, and a willingness to take commercial cards without a penalty are how you get paid in 48 hours without training the customer to leave. That is supplier payment solutions as a cash-cycle product, not as a fee argument.
The honest comparison table, written out
Your cost: optimization falls 0.45–1.5% on qualifying volume; surcharge can take your cost near zero while moving the cost to the customer. Customer’s cost: nothing changes versus up to 2.4%. Notice: none versus immediate. DSO: neutral to improved versus longer on large accounts. Rules: optimization does not add a line to the invoice; surcharge caps and prohibitions vary by market — confirm with counsel.
We will surcharge the small-ticket tail where nobody switches, when the mix warrants it. We will not recommend a blanket B2B surcharge as the default. The commission on surcharge is higher. The relationship is worse. A 55-year-old controller already knows which of those two sentences is the business.
When surcharge is still the correct tool
Small average tickets. A buyer base that will not operationalize EFT. A file with little commercial volume, so there is nothing to optimize. Where surcharging is prohibited, split the book. If those conditions describe you, say so on the audit form. We would rather place the correct product than win an argument on this page.
If those conditions do not describe you — $2M–$25M distributor, commercial cards, tickets in the thousands — start with the fee audit. Then read the factoring page only for the invoices that should stay on terms. Do not surcharge your way out of a DSO problem. That is how you get paid slower on the accounts that matter.
Worked dollars, then the decision
A $12.5M book, 28% card, 55% commercial: commercial volume $1.925M. Optimization at the 0.65% midpoint is about $12,500 a year, customer cost unchanged, settlement still 48 hours. Surcharge at 2.4% on the same commercial book is $46,200 a year — paid by the customer — and a modelled 30–50% of that volume walks to EFT within twelve months. After a 40% walk, you have kept $27,720 of surcharge income and lost the float-for-cash trade on $770,000 of volume. That is not a win. It is a smaller book with angrier house accounts.
On the $47,000 invoice, 2.4% is $1,128. On the $800 invoice it is $19. If 80% of card volume sits above $5,000, surcharge is the wrong default. If 80% sits below $1,000, surcharge on the tail can be the correct tool and optimization still belongs on the commercial remainder. Mix decides. Commission does not.
Surcharge rules vary by market. Some prohibit it. Confirm with counsel on a named file. Legality was never the interesting part. The interesting part is whether you still want those customers to pay by card once you have taxed the float.
How to get paid faster as a wholesale distributor, without the surcharge
Cut the take-rate into the published commercial range. Put a payment link on every invoice. Show open balances in a portal. Settle in 48 hours. Keep the customer on their purchasing-card program. Fund the remainder that should stay on terms with factoring at 1.5–4.5% per 30 days, or with a line if you can get one cheaper. That sequence is supplier payment solutions as a cash cycle. Surcharge is a shortcut that trains the account to leave.
We will tell you if surcharge is still the right tool on the small-ticket tail. We will not pretend a blanket B2B surcharge is interchange optimization with a higher commission. The comparison is honest because both options are on this page, including the one that pays us less.
A controller comparing the two will rebuild the dollars. Take last month’s card volume. Multiply by 2.4% for the surcharge case. Multiply the commercial share by 0.45%, then by 1.5%, for the optimization envelope. Put both next to DSO. If surcharge is larger on paper, ask what share of volume you are willing to lose. The modelled 30–50% migration is labelled illustrative because it is not an observed panel. The direction is not in dispute. Large tickets leave. Those were the tickets that made 48-hour settlement valuable.
Is surcharging the right tool for B2B? Published caps are often 2.4% on credit. Debit is often outside that framework. Some markets prohibit it. Confirm with counsel on a named merchant. Then ignore legality and ask whether you want the house account to keep a purchasing card. If yes, do not tax the float. Cut the take-rate instead. If the tickets are small and the buyers will not operationalize EFT, surcharge the tail and still optimize the commercial remainder. Mix decides. A slogan does not.
How to get paid faster as a wholesale distributor is not a surcharge question. It is a rails question: 48 hours versus 45 days on the card slice, and a facility on the rest. Processing charge difference versus advertised 2.9% + $0.30 is the first subtraction. Published commercial range 0.45–1.5% is the second. Published average interchange near 1.4% is context, not a quote. The statement is the measurement. The finding is the artifact. This article is the comparison so you do not have to hear only the product that commissions higher.
