Understanding Pricing Models in Payment Processing
When it comes to accepting credit and debit card payments, the pricing model your payment processor uses can significantly impact your bottom line. Payment processors primarily use three common pricing models—Interchange Plus, Tiered Pricing, and Flat-Rate Pricing—plus a less frequent model known as Subscription or Membership Pricing. Each comes with its own structure, level of transparency, and cost implications.
Interchange Plus Pricing (Cost-Plus Pricing)
This model is widely considered the most transparent. With interchange plus, businesses pay the actual interchange fee set by the card networks (like Visa or Mastercard), plus a small, fixed markup set by the payment processor. The markup may be a flat fee per transaction, a small percentage, or both. While the total cost can vary per transaction—because interchange fees vary—the processor’s margin is clear, so businesses know exactly what they’re paying over the base cost.
Tiered Pricing
With tiered pricing, transactions are grouped into predefined categories or tiers—typically qualified, mid-qualified, and non-qualified—each with its own rate. The tier is determined based on perceived risk and card type. For example, a basic debit card may fall under the qualified tier (lowest cost), while a premium rewards credit card might fall into the non-qualified tier (highest cost). The downside? It’s often unclear how transactions are categorized, making it harder for merchants to predict or verify actual costs.
Flat-Rate Pricing
Flat-rate pricing is straightforward and often favored by small or seasonal businesses. Merchants pay the same fixed percentage and/or flat fee per transaction, regardless of the card type or method of payment. This simplifies billing and makes costs predictable, but that convenience often comes at a premium: the rate is typically higher than what you'd pay under interchange plus, especially for lower-risk or debit transactions.
Subscription / Membership Pricing
A newer and less common model, subscription pricing charges businesses a monthly membership fee in exchange for access to lower per-transaction costs. It works similarly to interchange plus—interchange fees are passed through—but the processor markup is a flat fee per transaction, rather than a percentage. This model can offer savings to businesses with high volume or larger average transactions, but may not be ideal for smaller operations.
Which Pricing Model Is Best?
Each model has pros and cons, and the best fit depends on your business type, transaction volume, and the cards your customers typically use. For example:
- Interchange plus is best for transparency and cost control.
- Flat-rate is ideal for simplicity and low-volume sellers.
- Tiered pricing is common but often lacks clarity.
- Subscription pricing can benefit high-volume merchants looking for low, fixed transaction fees.
