For B2B merchants using Authorize.net, submitting Level 3 detail-Authorize.net is one of the most overlooked interchange optimization opportunities available. Authorize.net does not automatically submit Level 3 enhanced data on commercial and government card transactions through its standard virtual terminal — which means many merchants using Authorize.net for B2B payments may be leaving significant interchange savings on the table without knowing it. Revolution Payments has the back-end interchange optimization capability to identify qualifying cards, automatically submit Level 3 detail, and help ensure eligible transactions qualify for the lowest available interchange rate.

Authorize.net is one of the most widely used payment gateways in the country. For B2B merchants accepting commercial and government cards through Authorize.net, there is a significant interchange optimization opportunity that most accounts are missing — and it starts with Level 3 data.

What Authorize.net Level 3 Processing Actually Means

Authorize.net supports submitting Level 3 data when the processor or acquirer connection permits — but this capability is connection-specific and requires integration via the Authorize.net API. The standard Authorize.net virtual terminal typically passes Level 2 data at best on commercial card transactions, leaving B2B and government card transactions without the enhanced line-item detail required to qualify for lower interchange categories.

This matters because interchange — the fee paid to the card-issuing bank on every transaction — represents the majority of total credit card processing costs. For commercial cards, the interchange rate depends heavily on whether the right enhanced data is submitted with each transaction. Without Level 3 data, those transactions default to a significantly higher interchange category. With it, the cost can be reduced by up to 30% to 40% on eligible transactions.

How Revolution Payments Handles This

Revolution Payments provides back-end interchange optimization that works alongside the Authorize.net gateway. The solution identifies commercial and government cards at the time of the transaction and automatically submits the required Level 3 line-item data — including purchase order number, item description, quantity, unit of measure, unit cost, tax amount, freight amount, and postal codes — without any manual data entry required from the merchant or their team.

The result is that eligible commercial and government card transactions clear at the lower Level 3 interchange category rather than defaulting to the standard rate. For merchants processing significant B2B volume through Authorize.net, the difference in interchange cost represents real money that currently flows out before the processor’s markup is ever applied.

Current Interchange Rates — What You Are Actually Paying

The difference between a standard commercial card rate and a properly optimized Level 3 rate is significant. The table below shows current government purchase card interchange rates as of August 2026. Rates are subject to change — verify current rates with your processor.

High Ticket Interchange for Level 3 Detail Authorize.net Users

For Authorize.net users processing large individual commercial or government card transactions, there is an additional opportunity beyond standard Level 3 interchange optimization. Visa and Mastercard each have separate large ticket interchange programs that offer even lower rates on eligible transactions above specific thresholds.

• Visa Large Ticket — transactions of $7,555  and above may qualify for significantly reduced interchange rates with correct Level 3 data submission
• Visa GSA Large Ticket — government purchase card transactions of $5,557.14 and above may qualify for 1.20% + $39.00 as of August 2026
• Mastercard Large Ticket — transactions of $10,000 and above qualify for a tiered large ticket interchange program with rates as low as 0.70% on transactions above $1,000,000

Qualifying for these large ticket interchange programs requires Level 3 data to be submitted correctly on each eligible transaction and the merchant account to be properly configured for the applicable program. For Authorize.net users processing high-value B2B or government transactions who have never had their interchange qualification reviewed — this is one of the most overlooked cost reduction opportunities available.

What to Check on an Authorize.net Account for Level 3 Qualification

• Is the account configured for Level 3 data submission? Authorize.net’s standard virtual terminal typically passes Level 2 data only. Level 3 requires the right processor connection and back-end configuration.
• Are commercial card transactions clearing at the CEDP Verified rate? A statement review will show exactly what interchange category each transaction cleared at — and whether the account is qualifying correctly or defaulting to a higher rate.
• Are there STND or EIRF charges on the statement? These codes indicate transactions that downgraded — meaning required data was missing and the transaction did not qualify for the lower available interchange rate.
• Do large transactions qualify for high ticket interchange programs? Visa transactions above $7,500 and Mastercard transactions above $10,000 may qualify for additional interchange savings — but only with Level 3 data and proper account configuration.
• Is the processor connection capable of passing Level 3 data through Authorize.net? This is connection-specific. Not all processor and gateway combinations support full Level 3 data submission.

Revolution Payments and Level 3 Detail Authorize.net

Revolution Payments has specialized in Level 3 interchange optimization for B2B and government merchants for over 25 years. The back-end interchange optimization solution works alongside the Authorize.net gateway — automatically identifying qualifying cards and submitting the required Level 3 detail on eligible transactions without disrupting existing workflows or requiring manual data entry.

For Authorize.net users currently processing commercial or government cards and unsure whether transactions are qualifying at the Level 3 interchange rate — a no-cost statement review will show exactly what interchange categories transactions are clearing at and whether there is a configuration issue causing eligible transactions to default to a higher rate.  In fact when you process a commercial card in Auth.net without level 3 optimization you end up paying 80-1.20% higher in interchange fees before a processor ads their rate.

Send a recent processing statement for a no-obligation review. If transactions are already qualifying correctly, that will be the first thing communicated. If they are not, the review will show exactly where the additional interchange cost is coming from and what it would take to address it.
