B2B Payment Processing
B2B businesses have access to lower interchange rates than most processors will tell them about. Level 2 and Level 3 data processing, ACH, invoicing, and ERP integrations built for businesses that bill other businesses.
How B2B Payment Processing Is Different
B2B payments are not just larger versions of consumer transactions. They involve different card types, different risk profiles, and significant rate reduction opportunities that most processors ignore.
When a business customer pays you with a corporate purchasing card or commercial credit card, the transaction runs through the same Visa and Mastercard networks as a consumer card purchase. But the underlying economics are different. Corporate cards are issued to businesses for business expenses, and Visa and Mastercard have established a tiered rate structure specifically for these transactions that rewards merchants who submit enhanced transaction data.
Most small business processors do not support this enhanced data submission. They process your B2B corporate card transactions at standard interchange rates, keeping the lower B2B rates inaccessible to you. GoPayhawk supports Level 2 and Level 3 data submission, which qualifies eligible transactions for meaningfully lower interchange rates. For B2B businesses processing high volumes on corporate cards, this is often the single largest savings opportunity in their payment setup.
Large Ticket Sizes, High Stakes
B2B transactions are often large: a contractor invoicing $5,000 for a job, a distributor billing $12,000 for a product order, a professional services firm charging $8,000 for a month of work. At a 2.5% effective rate on a $5,000 transaction, you pay $125 in processing fees. At 1.8% with Level 2/3 data on the same transaction, you pay $90. That $35 difference on a single invoice becomes a material annual number across dozens of similar transactions each month. Flat-rate processors do not differentiate transaction size or card type, which means B2B merchants consistently overpay.
Corporate Card Mix
Business customers typically pay with corporate purchasing cards, company credit cards, or fleet cards rather than consumer debit cards. These card types carry higher base interchange rates than consumer cards, which is exactly why the Level 2 and Level 3 programs exist: to give merchants a way to reduce the cost of accepting these commercial cards when they submit additional transaction data. If your customer base is predominantly business buyers, your card mix almost certainly contains card types where Level 2/3 processing produces real savings.
Invoice-Based Payment Workflows
Most B2B businesses do not have a counter. They send invoices and wait for payment, sometimes weeks after the work is done. That creates a different workflow than retail: you need to accept cards by phone, through a payment link, or via a virtual terminal. Card-not-present B2B transactions carry higher base interchange rates than in-person transactions. Combined with Level 2/3 data submission and the option to offer ACH payment on large invoices, GoPayhawk gives B2B merchants the tools to keep total collection costs as low as possible across all payment methods.
What Level 2 and Level 3 Data Actually Means
These are the enhanced data fields that qualify B2B transactions for lower interchange rates. Most processors do not submit them. GoPayhawk does.
The key requirement is that your payment processor and gateway support submission of Level 2 and Level 3 data fields alongside the transaction. If your current processor does not support this, you are likely paying standard corporate card interchange rates on every transaction that could qualify for a lower rate. A statement analysis will show you which transactions could have qualified and what the savings would look like.
Which Pricing Model Is Right for B2B?
The pricing model matters more for B2B than almost any other industry, because flat-rate pricing completely neutralizes the Level 2/3 advantage.
| Pricing Model | How It Works for B2B | Level 2/3 Benefit | Best When |
|---|---|---|---|
| Interchange Plus Recommended for B2B |
You pay the actual card network interchange cost plus a fixed markup. Level 2/3 savings pass directly to you as lower interchange on qualifying transactions. | Full benefit: lower interchange rates appear directly on your statement. | All B2B businesses with meaningful corporate card volume |
| ACH Payments | Bank-to-bank transfers at a flat per-transaction fee rather than a percentage. Ideal for large invoices where even 1.5% is a significant dollar amount on a single payment. | Not applicable (no interchange on ACH). | Large invoices over $2,000 where flat ACH fee is lower than card processing cost |
| Flat Rate | Fixed percentage on every transaction. Your processor captures all Level 2/3 interchange savings as their own margin. You pay the same regardless of card type or data submitted. | None: flat-rate processors keep the Level 2/3 savings. | Not recommended for B2B businesses with meaningful corporate card volume |
| Surcharging | Credit card users pay a surcharge of up to 3%. Applicable to corporate cards in most states. Requires card network registration and compliant terminal setup. | Partial: surcharging eliminates your cost but does not reduce interchange directly. | B2B businesses with consistent credit card usage whose customer relationships accept surcharging |
| Cash Discounting | Posted price is the card price; customers paying by check or ACH pay a lower amount. Works well in B2B invoice workflows where two prices can be clearly displayed. Legal in all 50 states. | Not directly applicable to interchange, but eliminates card processing cost on transactions that shift to ACH. | B2B businesses with invoice workflows that can clearly display dual pricing |
Required Features for B2B Payment Processing
B2B payment processing needs are different from retail. These are the features that matter most when your customers are businesses.
Level 2 and Level 3 Data
GoPayhawk supports Level 2 and Level 3 data submission for qualifying B2B corporate card transactions. This is the primary cost-reduction tool for B2B merchants and is not offered by most flat-rate or self-service processors. Your account manager will configure data submission for your specific transaction and invoice types.
ACH Payments
Accept bank-to-bank ACH payments from business customers at a fraction of credit card processing costs. ACH is particularly valuable for large recurring invoices where even a modest percentage fee adds up to a significant dollar amount. Offering ACH alongside card acceptance gives your customers the option to choose the lower-cost payment method.
Invoice Payment Links
Send a secure payment link alongside your invoice so customers can pay online by card or ACH without requiring a terminal on your end. Invoice payment links are the standard B2B collection tool for contractors, professional services firms, and any business without a customer-facing location.
Recurring Billing
For retainer clients, ongoing contracts, and subscription services, automated recurring billing reduces the monthly collection friction. Automated payment scheduling, failed payment retry logic, and customer notification flows. Your account manager configures the billing schedule that matches your contract structure.
Virtual Terminal
A web-based interface for manually processing card payments over the phone or via email authorization. Essential for B2B businesses that do not have a physical counter and need to process customer-provided card numbers. Virtual terminal transactions benefit from Level 2/3 data submission where the card type qualifies.
Detailed Reporting
Transaction-level reporting showing card type, interchange category, and fee breakdown per transaction. For B2B merchants, this visibility is essential for verifying that Level 2/3 qualifying transactions are actually being processed at the lower rate. GoPayhawk's portal gives you the data to confirm your savings month over month.
Accounting, ERP, and Business System Integrations
GoPayhawk connects to the accounting and ERP platforms that B2B businesses rely on, so payments and invoices stay in sync without manual data entry.

What Level 2/3 Processing Actually Saves
Here is what the interchange rate difference looks like in real dollars for a typical B2B business.
Example: B2B Business, $75,000/Month, Primarily Corporate Card Payments
Assumptions: approximately 150 transactions per month at an average of $500 per invoice. All transactions are on Visa or Mastercard corporate purchasing or commercial cards.
Without Level 2/3 data (standard corporate card interchange, approximately 2.5% effective):
2.5% of $75,000 = $1,875/month
With Level 2 data submitted (typical reduction to approximately 2.1% effective):
2.1% of $75,000 = $1,575/month — saving approximately $300/month
With Level 3 data submitted (typical reduction to approximately 1.7% to 1.9% effective):
1.8% of $75,000 = $1,350/month — saving approximately $525/month versus standard rates
Annual savings from Level 2/3 alone: approximately $3,600 to $6,300
If a portion of those invoices are paid by ACH instead of card, the per-transaction cost is typically a flat fee rather than a percentage, reducing cost further on the largest invoices.
Rate reductions are estimates based on typical Level 2/3 interchange reductions for qualifying Visa and Mastercard corporate card transactions. Actual savings depend on your specific card mix, transaction data eligibility, and whether transactions qualify for Level 2 or Level 3 classification. Submit your statement for an exact analysis.
The math above assumes all transactions qualify for Level 2 or Level 3 rates. In practice, the qualifying percentage depends on what card types your customers use. Your account manager will review your current statement to estimate what portion of your transactions are on qualifying commercial card types and produce a realistic projection for your business specifically.
If you are currently on a flat-rate processor, none of the Level 2/3 savings are reaching you. The interchange rate reduction is happening at the network level, but your processor is capturing the difference as margin rather than passing it through to you.
B2B Business Types We Work With

B2B Payment Processing FAQ
Level 2 and Level 3 are enhanced data interchange categories for commercial and corporate card transactions. When a merchant submits additional transaction data alongside a qualifying B2B payment, the card networks classify it at a lower interchange rate. Level 2 adds sales tax, purchase order number, and postal code. Level 3 adds full line-item detail. Most processors do not support this data submission, which means B2B merchants on those platforms pay standard rates even on transactions that could qualify for lower rates.
Any B2B business whose customers pay with corporate purchasing cards, fleet cards, or commercial credit cards benefits from Level 2/3 processing. This includes contractors, HVAC companies, wholesale distributors, professional services firms, staffing companies, and any business that regularly invoices other businesses. The savings are largest for businesses with high average ticket sizes on corporate cards, since the rate reduction applies to the full transaction amount.
Yes. GoPayhawk supports ACH payments, which allow business customers to pay directly from their bank account at a flat per-transaction fee rather than a percentage. For large B2B invoices, offering ACH as a payment option can substantially reduce your effective processing cost. Your account manager can configure ACH acceptance alongside card processing so customers can choose their preferred method.
GoPayhawk supports invoice payment links, which let you send a secure payment link alongside your invoice so customers can pay online by card or ACH. Payment links pair with accounting integrations like QuickBooks or Microsoft Dynamics 365 to keep your records in sync automatically. This is the standard collection model for B2B businesses without a customer-facing counter.
Interchange-plus is the best pricing model for most B2B businesses because it allows Level 2 and Level 3 rate reductions to pass directly to the merchant. Under flat-rate pricing, your processor captures the interchange savings from qualifying corporate card transactions as their own margin. Under interchange-plus, lower rates on qualifying B2B transactions reduce your effective rate directly, which is why interchange-plus and Level 2/3 work together as a system.
Yes. GoPayhawk has a featured integration with Intuit QuickBooks that syncs transactions automatically to QuickBooks Online or Desktop. GoPayhawk also integrates with Microsoft Dynamics 365, Oracle NetSuite, and Odoo. Your account manager confirms the specific setup for your accounting system during onboarding so payments and invoices stay in sync without manual data entry.
GoPayhawk supports large B2B transactions through its acquiring relationship with Elavon. For very large invoices, your account manager can advise on transaction limits, split tender options, and whether ACH would be more cost-effective for specific invoice sizes. The dedicated account model means you have a real person to call when a large transaction needs attention rather than navigating a ticket queue.
Level 2 and Level 3 rates apply based on the card type being used, not your specific industry. If your customer pays with a Visa or Mastercard corporate purchasing card, fleet card, or commercial card, and you submit the required additional data, the transaction qualifies regardless of whether you are a contractor, distributor, professional services firm, or any other B2B category. The key requirement is that your processor supports Level 2/3 data submission, which GoPayhawk does.
