    # Understanding Interchange-Plus: The Secret to Lower Processing Fees for Wisconsin Small Businesses


    If there is one thing Wisconsin business owners are known for, it’s hard work and a keen eye for value. Whether you’re running a bustling diner in the heart of Madison, a family-owned hardware store in Eau Claire, or a boutique in Cedarburg, you know that every cent counts.


    However, when it comes to credit card processing, many local business owners feel like they’re reading a foreign language. You see terms like "flat-rate," "tiered pricing," and the gold standard: Interchange-Plus.


    Today, we’re going to pull back the curtain on Interchange-Plus pricing. Once you understand how it works, you’ll realize why it’s often the most transparent and cost-effective way to handle your business’s payments.


    The Three Layers of Credit Card Processing Fees


    To understand Interchange-Plus, you first have to understand the three entities that get a piece of every transaction:


    1. The Card Issuing Bank: The bank that issued the card to your customer (e.g., Chase, Wells Fargo, a local Credit Union). They take the largest share, known as the Interchange Fee.

    2. The Card Brands: Visa, Mastercard, Discover, and American Express. They charge Assessment Fees.

    3. The Processor: This is the company that provides your equipment and connects your business to the banking networks. This is where Wisconsin Electronic Payments fits in.


    What Exactly is Interchange-Plus?


    In a "Flat-Rate" model (think Square or PayPal), you might pay a flat 2.6% + $0.10 for every transaction. It’s simple, but it’s often very expensive because the processor keeps the difference between that flat rate and the actual cost.


    Interchange-Plus is different. It is a "cost-plus" model.


  1. Interchange: You pay the exact, raw cost of the transaction charged by the banks and card brands.
  2. Plus: You pay a small, fixed markup to your processor for their services.

  3. Let’s look at a real-world Wisconsin example:

    Imagine a customer buys a $100 jacket at your shop in Green Bay using a basic debit card.

  4. The Interchange cost for that debit card might only be 0.05% + $0.21.
  5. With a Flat-Rate of 2.6%, you’d pay $2.60.
  6. With Interchange-Plus (assuming a markup of 0.20%), you might only pay $0.46.

  7. In this scenario, you just saved over $2.00 on a single transaction. Over the course of a Fish Fry Friday or a busy weekend at the farmer’s market, those savings add up to thousands of dollars a year.


    Why Interchange-Plus is the Better Choice for Wisconsin Locals


    1. Complete Transparency

    With Interchange-Plus, your monthly statement shows exactly what the banks charged and exactly what your processor earned. There are no "hidden" categories or "non-qualified" surcharges that suddenly inflate your bill at the end of the month.


    2. Lower Costs on Lower-Risk Cards

    Not all credit cards are created equal. A "Rewards" card costs more to process than a standard debit card. With flat-rate pricing, you pay the high price for every card. With Interchange-Plus, when a customer pays with a low-cost debit card, you keep those savings.


    3. Business-to-Business (B2B) Savings

    If you run a manufacturing shop in Milwaukee or a wholesale nursery in the Fox Valley, you likely deal with corporate cards. Interchange-Plus allows you to utilize "Level 2 and Level 3" data, which can significantly lower the interchange rates on corporate and government cards—savings that stay in your pocket.


    Actionable Tips for Reducing Your Rates Today


    If you’re ready to stop overpaying for your processing, here are three steps you can take right now:


  8. Review Your Statement: Look for the term "Non-Qualified" or "Mid-Qualified." If you see these, you are on a Tiered Pricing plan, which is almost always the most expensive way to process.
  9. Ask About Wholesale Rates: Contact your current provider and ask if they offer Interchange-Plus. If they hesitate or say "you’re too small for that," it’s time to look for a local partner.
  10. Batch Out Daily: In Wisconsin, we know the value of a routine. Ensure your terminal batches out every night to ensure you get the best possible interchange rates for each day's transactions.

  11. The Value of a Local Partner
