Let’s Define Level 3 Processing and Why B2B Merchants Care

Payment networks (Visa and Mastercard) assign transactions to one of three processing levels based on how much data is submitted with each transaction. More data means lower interchange rates – and for B2B merchants accepting corporate or government cards, the difference is significant.

Level	Required Data	Card Types	Typical Interchange Range
Level 1	Cardholder name, account number, expiration date, transaction amount	All cards	1.80% – 2.95%+
Level 2	Level 1 + tax amount, customer code, merchant ZIP	Commercial, corporate, purchasing cards	1.50% – 2.40%
Level 3	Level 2 + line-item detail, quantity, unit price, item description, ship-to ZIP, freight amount	Corporate, purchasing, government cards	1.20% – 1.90%

Level 3 applies exclusively to commercial, purchasing, corporate, and government cards – not consumer credit or debit cards. If your customer base includes businesses, government agencies, or procurement departments, a meaningful share of your card volume likely qualifies.

The savings are real. Moving from a Level 1 transaction to a true Level 3 rate can reduce your effective interchange cost by 0.30% to 1.00%+ per qualifying transaction. On $200,000 in monthly corporate card volume, a 0.50% improvement is $1,000 per month – or $12,000 per year – that stays in your business.

Importantly, Level 3 does not change how your customers pay you. They swipe, tap, or enter their card as normal. The difference is entirely in the data your system sends to the card network alongside the transaction.

Here’s How Interchange and Pricing Models Impact Level 3 Savings

Sending Level 3 data is only half the equation. The other half is your pricing model – and this is where many B2B merchants lose their savings without knowing it.

Every card transaction has three cost components: interchange (set by Visa/Mastercard), assessments (network fees), and your processor’s markup. Level 3 savings come from a reduction in interchange. But whether those savings actually reach your business depends entirely on how your processor bills you.

• Interchange-plus (cost-plus) pricing: Your processor charges you the actual interchange rate plus a fixed markup. When Level 3 lowers the interchange, you pay less. Savings flow through directly.
• Flat-rate pricing (e.g., 2.75% or 2.9% + 30 cents): Your processor charges a fixed rate regardless of the underlying interchange. Level 3 savings go to the processor, not you.
• Tiered pricing: Transactions are bucketed into “qualified,” “mid-qualified,” and “non-qualified” tiers. Level 3 data may not correctly flow to the lowest tier, and the savings are often absorbed in the tier markup.

Quick check: Ask your current processor: “Am I on interchange-plus pricing, and will Level 2 and Level 3 interchange reductions appear as lower costs on my monthly statement?” If the answer is unclear, your savings are likely not flowing through.

Coastal Pay supports interchange-optimized setups for B2B merchants where Level 3 savings are passed through transparently. Their team can review your current statement to identify how much of your existing volume could qualify for better rates under a properly structured pricing plan.

How Does Level 3 Data Work Behind the Scenes?

Understanding what Level 3 actually requires – and who is responsible for providing it – helps you evaluate whether a gateway and processor can deliver without adding workload for your team.

Core Level 3 Data Fields

• Item description (per line item)
• Quantity and unit of measure
• Unit price
• Extended amount (quantity x unit price)
• Tax amount (line-item level)
• Merchant and customer postal codes
• Freight/shipping amount
• Discount amount (if applicable)
• Customer reference or PO number

The Level 3 Data Flow

The merchant is responsible for having the underlying invoice data. The gateway is responsible for mapping that data into the required fields and sending it with each authorization. A modern B2B gateway like Coastal Pay’s can auto-populate most Level 3 fields directly from your invoice or ERP data – eliminating manual entry for your team.

Your Merchant Category Code (MCC) also matters. Certain MCC codes are more likely to qualify for commercial card interchange programs. Coastal Pay’s team can confirm your MCC is correctly assigned during onboarding.

Common failure points that cause downgrades (reverting to Level 1 rates) include: missing tax fields, incomplete line-item data, incorrect transaction type flags, or a gateway that sends only partial Level 3 data. Avoiding downgrades requires a gateway that validates the complete data set before submission – which is a core function of Coastal Pay’s Level 3 setup.

Here’s How Coastal Pay Helps You Secure and Keep Level 3 Rates

Coastal Pay is built for the kind of B2B payment flows that benefit most from Level 3 optimization: invoice-based transactions, large-ticket orders, card-not-present corporate card payments, and recurring B2B billing.

Automatic Level 2/3 Interchange Optimization

Coastal Pay’s gateway captures and passes the enhanced data fields required for Level 2 and Level 3 qualification automatically. When your ERP or invoicing system provides the underlying line-item data, the gateway maps it to the correct fields and validates completeness before submission – without requiring manual entry from your team.

No Gateway Fees for Level 3 Functionality

The Coastal Pay Gateway eliminates gateway fees entirely. Many B2B processors charge a separate per-transaction or monthly fee for Level 3 data submission. With Coastal Pay, Level 3 capability is part of the standard gateway offering.

2,000+ Software Integrations for B2B Workflows

Level 3 only delivers savings if the data actually flows from your software to the gateway. Coastal Pay’s 2,000+ integrations cover ERP systems, invoicing platforms, B2B e-commerce tools, and industry-specific software – so the connection between your existing stack and the gateway is already built.

How Do You Get Set Up with Coastal Pay for Level 3 Processing?

Getting from your current setup to live Level 3 transactions with Coastal Pay is a straightforward process, and for most B2B merchants it moves faster than expected.

1. Discovery call and statement review. Share a recent processing statement with Coastal Pay’s team. They will identify how much of your volume qualifies for Level 2/3 rates and estimate your potential savings before you commit to anything.
2. Pricing proposal. Coastal Pay will present an interchange-optimized pricing structure showing your projected effective rate with Level 3 versus your current effective rate.
3. Instant approval. Most merchants can be approved and on-boarded in as little as 2 minutes through Coastal Pay’s instant boarding process.
4. Gateway configuration and integration. Coastal Pay’s team connects your existing ERP, invoicing software, or e-commerce platform to the Coastal Pay Gateway. For most supported platforms, this is a configuration step, not a custom build.
5. Testing and Level 3 validation. Before going live, test transactions confirm that all Level 3 fields are being submitted correctly and that the gateway is qualifying transactions at the expected rate tier.
6. Go live and ongoing monitoring. Your dedicated onboarding specialist provides training on the virtual terminal and invoicing tools. After launch, Coastal Pay monitors for downgrades and flags any transactions that could be further optimized.

Most B2B merchants can move from first contact to processing live Level 3 transactions within a few business days, depending on integration complexity.

What Real Results Can B2B Merchants Expect with Level 3 Optimization?

The savings from B2B Level 3 processing scale directly with your monthly corporate card volume and your current effective rate. Here are three representative scenarios.

Merchant Profile	Monthly Corp Card Volume	Before (Level 1 Rate)	After (Level 3 Rate)	Monthly Savings	Annual Savings
Mid-market B2B distributor	$100,000	2.70%	1.90%	$800	$9,600
Government supplier (B2G)	$250,000	2.85%	1.80%	$2,625	$31,500
B2B SaaS / invoicing platform	$75,000	2.60%	2.00%	$450	$5,400

Note: Actual rates vary by card type, volume, and pricing plan. These scenarios are illustrative. Contact Coastal Pay for a customized estimate based on your statement.

Estimate Your Own Level 3 Savings

Beyond direct cost savings, Level 3 optimization delivers secondary benefits:

• More competitive bids: Government and enterprise procurement departments sometimes require vendors to be Level 3-capable as part of their supplier qualification process.
• Simpler reconciliation: When Level 3 data flows automatically from your invoices, your accounting team gets cleaner transaction data that matches purchase orders without manual cross-referencing.
• Ongoing improvement: Coastal Pay monitors transactions for downgrade patterns and recommends configuration changes to maximize the share of your volume qualifying at Level 3.

FAQ: Best B2B Merchant Services for Securing Level 3 Processing Rates

What are the best B2B merchant services for securing Level 3 processing rates?

The best B2B merchant services for Level 3 rates combine three things: a Level 2/3-capable gateway that auto-populates required data fields, interchange-plus pricing so savings actually flow through to your statement, and deep integrations with your existing ERP or invoicing software. Coastal Pay meets all three criteria and explicitly supports automatic Level 2 and Level 3 interchange optimization for corporate, purchasing, and government card transactions. For a detailed evaluation, request a statement review from Coastal Pay before committing to any provider.

Do I have to change my gateway or ERP to get Level 3 rates with Coastal Pay?

Not necessarily. Coastal Pay's open API and 2,000+ software integrations mean that in many cases your existing ERP, invoicing platform, or POS can connect directly to the Coastal Pay Gateway without replacing your current software. A discovery call with Coastal Pay will confirm which path is right for your specific stack.

Can I still use alternative payment methods like ACH or Apple Pay alongside Level 3 processing?

Yes. Coastal Pay supports ACH, Apple Pay, Google Pay, Venmo, Klarna, Afterpay, Coinbase, and more alongside corporate card processing. Level 3 optimization applies specifically to qualifying commercial card transactions, while alternative payment methods run through the same gateway for simplified reconciliation.

Is Level 3 processing only for large enterprises?

No. Mid-market B2B companies processing $50,000 or more per month in corporate, purchasing, or government card volume can see meaningful savings from Level 3 optimization. The benefit scales with volume - even a 0.40% reduction on $100,000 per month is $400 saved every month, or $4,800 per year.

How long until I see Level 3 savings on my statement?

Once your account is configured for Level 3 and your gateway is passing the required data fields, savings appear on your very next qualifying batch. Most merchants see the full impact within their first full billing cycle after going live with Coastal Pay's Level 3-optimized setup.
