Most NetSuite B2B Companies Leave Thousands on the Table in Processing Fees — Here’s Why, and How to Stop It

If your business sells to other businesses and accepts card payments through NetSuite, there’s a good chance you’re quietly paying more in processing fees than you need to. Not because of a bad contract. Not because of hidden charges buried in the fine print. But because of something most business owners have never heard of: Level 2 and Level 3 payment processing for NetSuite.

The good news: there’s now a straightforward, automatic way to fix it — without changing how your team works.

The Hidden Cost Inside Every Card Transaction

When a customer pays you by card — whether it’s a Visa, Mastercard, or corporate purchasing card — your payment processor charges you a fee called an interchange rate. This rate isn’t fixed. What drives it up or down is something most merchants never think about: how much structured data you send along with the payment.

To understand how payment processing fees are structured, it helps to know that card networks like Visa and Mastercard operate on a simple principle: the more verified data you provide about a transaction, the better they can assess risk — and the lower the fee they charge you. These data tiers have a name.

Level 1 (L1) is the baseline — the card number, the transaction amount, and the date. This is standard for most consumer checkouts. The network knows almost nothing about the purchase, so it charges the highest fees.

Level 2 (L2) adds a bit more context: tax amount, a customer reference or PO number, and your business’s postal code. A little more data, a noticeably lower rate.

Level 3 (L3) goes further — it includes full line-item detail: what was purchased, at what unit price, in what quantity, with what tax treatment, and where it was shipped. This is the level of transparency card networks reward most. In return, they offer their lowest possible interchange rates — often 0.5% to 1.5% lower than what you’d pay at Level 1.

To make that tangible: if your business processes $2 million a year in B2B card payments, that difference could mean $10,000 to $30,000 in annual savings. Recurring, every year.

Why Most B2B Businesses Still Pay Level 1 Rates

Here’s the problem: qualifying for Level 2 and Level 3 rates requires sending that extra data to the card network at the moment of each transaction. Most payment systems simply don’t do this. They transmit the minimum required to authorize the payment and stop there.

This means that even businesses using corporate purchasing cards — which are specifically designed to qualify for lower interchange rates — end up paying premium consumer-level rates, because nobody ever sends the richer data.

It’s not negligence. It’s a structural gap. The data already exists inside your business — your orders, your line items, your tax records — but your NetSuite payment gateway never reaches in to retrieve it and attach it to the transaction.

This is one of the most consistently overlooked opportunities in reducing interchange fees for businesses that sell to other businesses.

The B2B vs. B2C Distinction That Changes Everything

Not all card transactions carry the same fee profile, and understanding why is key to understanding the opportunity.

When a regular consumer pays with a personal Visa card, that’s a B2C transaction. The card network has limited context about the buyer, the purchase intent, or the business relationship behind it. Higher uncertainty means higher fees.

When a business pays another business using a corporate card or purchasing card, that’s a B2B transaction. These payments are typically planned, tied to a purchase order, made between known entities, and processed through formal procurement channels. The underlying risk is genuinely lower — and card networks know it.

That’s exactly why Visa and Mastercard built the Level 2 and Level 3 pricing tiers. They exist to reward B2B merchants who document and submit transaction context. The challenge is that most businesses have no reliable way to automatically detect which transactions are B2B at the moment of payment — let alone enrich them with the correct data on the fly.

That’s where SensePass for Oracle NetSuite changes the equation.

How SensePass Enables Level 2 and Level 3 Payment Processing for NetSuite

SensePass is a payment connector built natively for NetSuite — the ERP used by thousands of mid-market and enterprise B2B businesses to manage orders, invoices, customer records, and financials.

The insight at the core of SensePass is straightforward: NetSuite already holds every piece of data needed to qualify a B2B transaction for L3 rates. Customer records, order line items, product codes, tax amounts, PO references — it’s all there. The SensePass connector simply bridges the gap between that data and the payment processor.

Here’s what happens in practice:

When a payment comes in, SensePass automatically checks whether the paying entity is a business customer. If it is, the transaction is identified as B2B, and the connector assembles the relevant structured data directly from NetSuite — customer reference, tax amounts, line-item detail — and submits it alongside the payment at Level 3.

Your processor receives a fully enriched transaction. The card network classifies it at the lowest applicable interchange tier. You pay less. All of this happens automatically, in the background, without your team changing a single step of their workflow.

It also connects directly to automated payment reconciliation in NetSuite, so the lower fees and enriched transaction data flow cleanly into your ledger without manual intervention.

What This Means for Your Bottom Line

The impact is direct:

Lower processing costs on every qualifying B2B transaction. Payments that previously settled at standard L1 rates now qualify for L2/L3 pricing. The savings are real and they compound with volume.

No workflow changes for your team. Your finance and operations staff continue using NetSuite exactly as they do today. SensePass works at the payment processing layer — nothing changes at the surface.

No manual data entry or enrichment. The connector reads directly from existing NetSuite records. There’s no separate system to manage, no forms to fill in, no risk of human error degrading the data.

Automatic B2B identification. You don’t need to flag transactions manually or ask customers to self-identify. SensePass determines transaction type from the customer data already in NetSuite.

For a deeper look at the strategies B2B businesses use for saving on credit card processing fees, including Level 2/L3 data, processor negotiation, and payment method diversification, the SensePass resource library covers each in detail.

The Bottom Line

Card processing fees are among the most overlooked cost centers in B2B businesses. They don’t show up as a line item you consciously approved — they accumulate quietly with every transaction, month after month.

Level 2 and Level 3 payment processing for NetSuite exists precisely to address this. Card networks built these tiers to lower costs for merchants who demonstrate transaction transparency. The only reason most companies don’t benefit from them is that no one connected the data already inside their ERP to the payment layer that needed it.

SensePass makes that connection — and for businesses already running NetSuite, it’s a natural extension of infrastructure you’ve already invested in.

If your business processes meaningful volume in B2B card payments, the math is worth running. The data is already there. The savings are real. The only thing missing is the connector.
