If your company relies on Microsoft Dynamics GP credit card processing for B2B or B2G transactions, there’s a good chance you’re paying more in interchange fees than you should — not because of your processor’s markup, but because of how your transactions are qualifying behind the scenes. Most companies review their processor’s rate. Very few review whether their commercial card transactions are actually landing in the lowest interchange categories available. For companies accepting corporate purchasing cards, business cards, or government purchase cards, that gap can become substantial over time.
Microsoft Dynamics GP is built for complex B2B accounting workflows, detailed invoicing, and multi-entity environments. But many payment gateway integrations connected to Dynamics GP simply process the transaction without optimizing the interchange qualification process. That’s where Level 3 processing becomes important.
What Is Level 3 Processing?
Level 3 processing is a commercial card data standard used by Visa and Mastercard for B2B and government card transactions. When Level 3 data is transmitted with a transaction, the card brands classify the payment as a more transparent, lower-risk commercial transaction — which can qualify the merchant for significantly lower interchange costs.
Level 3 data typically includes:
- Product descriptions
- Quantities
- Unit costs
- Tax amounts
- Freight information
- Customer codes
- Invoice detail
Most of this information already exists inside Microsoft Dynamics GP invoices. The key is whether your payment gateway integration is actually capturing and transmitting that data when the transaction is processed.
Why Most Microsoft Dynamics GP Users Overpay on Commercial Cards
Most Microsoft Dynamics GP payment integrations focus on processing the payment itself — not on optimizing how the transaction qualifies at the interchange level. That means many transactions default into higher-cost interchange categories even though they may be eligible for lower commercial card rates.
For B2B companies processing large invoices, the difference can be meaningful. A $15,000 purchasing card transaction that fails to qualify correctly can cost significantly more in interchange fees than the exact same transaction processed with proper Level 3 data attached. The processor doesn’t flag the downgrade. The transaction still goes through normally. Most companies never realize it’s happening.
It’s also worth noting: Visa eliminated Level 2 interchange qualification for business cards in January 2026. Level 3 is now the primary path to reduced interchange for commercial card transactions in the B2B space.
How Level 3 Processing Works Inside Microsoft Dynamics GP
When properly integrated, the payment gateway automatically pulls line-item invoice data directly from Microsoft Dynamics GP and attaches it to eligible commercial card transactions during processing. This happens automatically — no workflow changes, no additional work for your accounting team.
A properly integrated Microsoft Dynamics GP credit card processing solution supports transactions at multiple stages:
- Customer level payments
- Sales order authorizations
- Invoice captures
- Credit memo refunds
Once approved, payments automatically update Accounts Receivable and General Ledger records inside Dynamics GP — reducing manual reconciliation and eliminating unnecessary double entry.
Government Purchase Cards and Microsoft Dynamics GP
For companies selling to federal, state, or local government agencies, Level 3 processing is especially important. Government purchase cards and GSA SmartPay cards generally require Level 3 data to qualify for the appropriate government interchange categories. Without it, transactions automatically downgrade into more expensive tiers.
One detail most processors don’t surface: cross-border fees apply to US government card transactions processed outside the US. If any part of your payment infrastructure routes through non-US systems, that can disqualify the transaction from Level 3 rates entirely. For companies with meaningful B2G volume, that’s a cost worth identifying.
What to Look for in a Microsoft Dynamics GP Payment Gateway
Not all Microsoft Dynamics GP payment gateway integrations are built the same. If you’re evaluating your current setup, here are the questions that actually matter:
- Does the gateway automatically detect commercial cards and attach Level 3 data?
- Does it pull invoice detail directly from Dynamics GP without manual input?
- Does it update AR and GL records automatically after approval?
- Is cardholder data stored in a PCI-compliant off-site environment?
- Can you see how your transactions are qualifying at the interchange level?
Most companies focus exclusively on processor pricing while overlooking how transactions are actually qualifying. That’s usually where the biggest gap is.
The Bottom Line
Microsoft Dynamics GP already contains the invoice and line-item data needed for Level 3 processing. The real question is whether your payment gateway integration is actually using it. For companies accepting commercial cards or government purchase cards, properly configured Microsoft Dynamics GP credit card processing can meaningfully reduce interchange costs while streamlining accounting workflow at the same time.
If your company has never benchmarked how its commercial card transactions are qualifying, it’s worth finding out. The number is usually bigger than people expect.

Frequently Asked Questions
Does Level 3 processing work with all versions of Microsoft Dynamics GP?
Most Level 3 payment integrations support Microsoft Dynamics GP 2010 and newer. Compatibility depends on the specific payment gateway integration being used.
What cards qualify for Level 3 processing?
Level 3 processing applies to Visa and Mastercard commercial purchasing cards and government purchase cards. Consumer cards, standard debit cards, and most standard business credit cards do not qualify for Level 3 interchange rates.
Does Level 3 processing require manual data entry?
No. When properly integrated with Microsoft Dynamics GP, Level 3 data is transmitted automatically from the invoice at the time of processing — no additional steps required.
What happened to Level 2 processing?
Visa eliminated Level 2 interchange qualification for business cards in January 2026. Level 3 remains the primary interchange optimization path for B2B merchants processing commercial cards.
Is Level 3 processing available in Canada?
Level 3 processing is a US market program and is not available in Canada. Canadian merchants have different interchange structures. If you process cross-border transactions between the US and Canada, it’s important to understand how those transactions are classified and whether cross-border fees affect qualification.
Can Level 3 processing reduce interchange costs?
Yes. Commercial card transactions properly qualified with Level 3 data can process at significantly lower interchange categories than transactions submitted without it. The savings vary based on card mix and transaction volume, but for B2B and B2G merchants the difference is typically meaningful.
