Best B2B Payment Gateway for Manufacturers and Distributors

Learn what manufacturers, distributors, wholesalers, and suppliers should look for in a B2B payment gateway, including ACH, Level 2/3, Smart Invoicing, APIs, webhooks and real support.

Presented by Allen Kopelman, CEO — Nationwide Payment Systems-Host of B2B Vault: The Biz2Biz Podcast

AI Overview

A B2B payment gateway for manufacturers, distributors, and wholesalers should do more than process credit cards. The best options support ACH, Smart Invoicing, Level 2 and Level 3 data, recurring billing, ERP and accounting integrations, APIs, webhooks, white-label payment experiences, and real support. For companies with large invoices, commercial cards, and slower accounts-receivable cycles, a gateway like NPSONE can help shorten payment delays, reduce manual work, and improve cash flow.

You Process $100,000 a Month — Does Flat-Rate Payment Processing Still Make Sense?

If your business is processing $100,000 per month in credit and debit card payments, you are no longer a tiny merchant

At that volume, payment processing deserves a closer look

A flat-rate payment company may have been a great choice when you were smaller

. It was easy to sign up, the pricing looked simple, and you did not have to think about interchange, card types, B2B transactions, transaction counts, average ticket size, or payment optimization

But once you are processing six figures every month, the math changes

The question becomes: Is flat-rate payment processing still convenient — or has it become expensive?

At Nationwide Payment Systems, this is exactly the type of account we would like to analyze

. Not because flat-rate pricing is automatically bad, but because at $100,000 per month, even small pricing differences can add up to real money

Start With the Annual Number

A business processing $100,000 per month is processing approximately $1.2 million per year

Now consider the impact of even a small pricing difference on $1.2 million

0.25% difference = approximately $3,000 per year
0.50% difference = approximately $6,000 per year
0.75% difference = approximately $9,000 per year
1.00% difference = approximately $12,000 per year

That is why six-figure monthly processing volume deserves a professional review

. A fraction of a percentage point may not sound important, but when multiplied across $1.2 million in annual card volume, it can become a meaningful operating expense

The First Question: What Are You Really Paying?

Many business owners know the advertised rate of their payment provider, but far fewer know their actual effective processing rate

Those are not necessarily the same thing

. Your effective processing rate is calculated by comparing total payment-processing costs to total payment-processing volume

\text{Effective Processing Rate} = \frac{\text{Total Processing Cost}}{\text{Total Processing Volume}}

For example, suppose you processed $100,000 and your total payment costs for the month were $3,200

. Your effective rate would be approximately 3.20%

That gives you a real number to work with, allowing you to start asking better questions

Why the Advertised Rate Does Not Tell the Whole Story

Flat-rate processors are built around simplicity

. That simplicity is valuable, but your business activity may be much more complicated than one advertised percentage

Factors That Influence Total Processing Cost:

Transaction fees
Online payment fees
Card-not-present transactions
Keyed payments
Recurring payments
International cards
Refund activity
Chargebacks
Instant transfer fees
Additional software services
Payment links
Invoicing tools

That is why the best way to evaluate your processing cost is to look at what actually happened over a meaningful period of time

Why We Prefer 90 Days of Data

One month can be unusual

. Maybe sales were exceptionally high, there was a large refund, there were several chargebacks, or your average sale changed

That is why Nationwide Payment Systems generally prefers to review approximately 90 days of payment data

What a 90-Day Review Reveals:

Total sales volume
Number of transactions
Average ticket
Refunds
Chargebacks
Total fees
Payment methods
Transaction environments

From there, we can estimate your real processing costs more accurately

You May Not Need Merchant Statements

Traditional merchant accounts usually produce monthly processing statements, but platforms such as Stripe, Square, PayPal, QuickBooks Payments, and similar providers often rely heavily on online dashboards

We can work directly with that data

Log into your dashboard and set the reporting range to approximately 90 days.
Capture the main dashboard showing gross sales, net sales, refunds, disputes/chargebacks, transaction count, and processing fees.
Download detailed reporting if available, or use a full-page screen capture to save the report as a PDF.

Give us the raw information and let us do the analysis

$100,000 in Volume Does Not Tell Us Enough

Two businesses may each process $100,000 per month and still have completely different payment economics

Business A: $100,000 monthly volume | $25 average sale | ~4,000 transactions per month
Business B: $100,000 monthly volume | $2,500 average sale | ~40 transactions per month

Same processing volume, but very different businesses

. Since many payment costs contain a per-transaction component, the average ticket can materially affect total cost

What Type of Business Are You?

Your business type matters too

. A restaurant processing $100,000 per month looks very different from a manufacturer, distributor, wholesaler, insurance agency, professional-services company, medical supplier, SaaS business, contractor, or e-commerce company

Payment networks classify businesses into merchant categories

. Those categories, transaction environments, and customer types can influence processing economics

How Much of Your Business Is B2B?

If a large percentage of your revenue comes from business customers, the payment strategy may need to be different

B2B companies often accept business credit cards, corporate cards, purchasing cards, commercial cards, and virtual cards

. Depending on the transaction type and payment technology, some B2B businesses may benefit from enhanced transaction data such as Level 2 and Level 3 data

That can be especially important for manufacturers, wholesalers, distributors, and suppliers

Card-Present Versus Card-Not-Present Matters

Where and how your customers pay affects your profile

. We evaluate whether transactions are:

Tapped or EMV chip inserted
Paid through a website or invoice
Called in or entered via virtual terminal
Enrolled in recurring billing
Processed through QuickBooks or an ERP system

A business doing most of its transactions face-to-face has a very different processing profile than a business sending $10,000 invoices electronically

If You Are Processing Large Invoices, ACH Should Be Part of the Conversation

Imagine you send customers invoices for $5,000, $10,000, $25,000, or $50,000

. Does every customer need to pay by credit card?

Probably not

Some will want the card for rewards, convenience, or internal procedures

. Others may be perfectly happy paying through ACH

Giving customers options (Card or ACH) becomes very important as average invoice sizes increase

Cost-Plus Pricing Can Be Worth Reviewing

Once you reach $100,000 per month, it becomes reasonable to compare your current flat-rate structure with a customized cost-plus model

Cost-plus pricing separates the underlying transaction costs from the processor’s agreed markup

. Instead of charging one broad percentage, the account is priced around the actual underlying payment costs plus the processor margin

The Goal Is Not to Find a Fake Low Rate

One of the biggest problems in the payment industry is the race to advertise the lowest number

. That is not how Nationwide Payment Systems approaches an account

. We are not interested in showing you a teaser rate that has nothing to do with what you will actually pay

We analyze your volume, average ticket, transaction count, business type, B2B percentage, payment methods, card-present vs. card-not-present mix, recurring activity, and large-ticket transactions to estimate your real cost under a different pricing model

At $100,000 a Month, Support Matters Too

Once your business is processing $100,000 per month, payment problems become expensive very quickly

If your system stops working, your account gets flagged for compliance, you receive an unexpected chargeback spike, or you have a funding issue, can you reach a real person?

At Nationwide Payment Systems, we believe payment processing should include both competitive economics and real support

Technology Matters More as You Grow

At $100,000 per month, businesses often need more than a basic card terminal

. You may need:

Smart Invoicing
ACH
Recurring billing
Payment links
Virtual terminals
E-commerce integrations
QuickBooks, Xero, or Sage integrations
ERP connectivity
API access & webhooks
Level 2 and Level 3 processing
Multi-user access & reporting

The payment system should fit the business — the business should not have to work around system limitations

Should You Pass Processing Costs to Customers?

If you process $100,000 every month, card-processing costs represent a significant annual expense

Depending on your business model, applicable laws, and card-brand requirements, options may include:

Surcharging
Dual pricing
Convenience fees
ACH alternatives

When implemented correctly, these programs can materially change the economics of accepting payments

What Does a 90-Day NPS Review Look Like?

Step 1

Send us a screenshot of your payment dashboard showing approximately 90 days of activity

Step 2

Send us a detailed report if available (or a full-page screen capture saved as a PDF)

Step 3

Tell us your business type, approximate B2B vs. B2C mix, payment methods, recurring activity, and invoice sizes

Step 4

We calculate your estimated effective processing costs and review the payment profile

Step 5

We estimate what the account could look like using Nationwide Payment Systems cost-plus pricing and other payment strategies to give you an actual comparison

What If Your Current Pricing Is Already Good?

If your current pricing is competitive, your technology works well, and your support is good, the analysis may confirm that you are already in a strong position

The purpose of the review is not to manufacture savings; it is to understand the account

. Now you know

What If You Are Paying Too Much?

Then you have options

Moving to cost-plus pricing
Adding ACH
Optimizing B2B transactions with Level 2 or Level 3 data
Implementing Smart Invoicing
Reviewing surcharging or dual pricing
Improving recurring billing

Sometimes the biggest savings come from changing the overall payment strategy rather than changing just one rate

$100,000 Per Month Is Enough Volume to Ask Better Questions

At $100,000 per month, your business is processing approximately $1.2 million per year

. Ask yourself:

What am I actually paying, and why?
Could I pay less with a cost-plus pricing model?
Could some customers pay through ACH instead?
Could my B2B transactions be optimized?
Could I pass some payment costs to customers legally and properly?
Is my current processor providing the technology and support my business needs?

Stop Guessing and Run the Numbers

If your company processes approximately $100,000 per month through Stripe, Square, PayPal, QuickBooks Payments, or another flat-rate processor, Nationwide Payment Systems can review your payment data

Start with approximately 90 days of dashboard data, send us the detailed report, and tell us about your business

. We will analyze the numbers and show you what your payment costs could look like using NPS cost-plus pricing, ACH, Smart Invoicing, B2B optimization, Level 2/3 processing, surcharging, or dual pricing

At $100,000 per month, payment processing is no longer a minor expense — it is worth knowing your numbers
