In the world of payment processing, merchants are often confronted with a crucial decision: which pricing model should they adopt?
Among the various pricing options available in payments, two stand out as the most popular and widely used: flat rate pricing and interchange plus pricing, also known as cost plus pricing.
Each of these models has its merits and considerations, and understanding the nuances between them is essential for businesses aiming to optimize their payment processing strategies.
Flat rate pricing simplifies the credit card processing cost structure by offering merchants a fixed percentage fee and a set transaction fee for each transaction processed. This pricing model is renowned for its predictability, often featuring rates like 2.9% and $0.30 per transaction.
With flat rate pricing, the type of credit card used by customers does not affect the cost to the merchant. Credit cards are categorized by their interchange fees, which represent the fees charged by banks and passed on to merchants. Under flat fee pricing, these differences in interchange fees are essentially smoothed out, providing a sense of simplicity and ease in understanding pricing.
While flat rate pricing offers a straightforward approach to payment processing costs, it’s essential to note that simplicity comes at a price. Generally, merchants on flat fee pricing may experience higher fees compared to interchange plus pricing, especially when dealing with an average transaction size above a certain threshold. The only scenario where flat fee pricing often proves more cost-effective is when dealing with small transactions, such as those found in quick-service stores, typically less than $5 per transaction.
Interchange plus pricing goes deeper into the intricacies of credit card fees by considering the underlying cost known as the interchange fee. Different types of credit cards come with varying interchange fees; for example, high-end credit cards may have significantly higher interchange fees compared to basic ones.
In an interchange plus pricing model, the fee charged to the merchant varies depending on the type of credit card used by the customer. However, what remains consistent is the markup applied to each transaction. This pricing structure empowers merchants to optimize their costs, as they pay lower fees for transactions involving basic credit cards and higher fees when processing high-end cards.
Understanding that the majority of credit card transactions in North America involve basic cards with lower interchange rates is crucial. This means that, for most businesses, the potential to benefit from lower fees is significant.
Here we explore the pros and cons of Interchange Plus and Flat Rate pricing models in payment processing. By looking at the strengths and weaknesses of each approach, you’ll gain a clearer perspective on how these models align with your specific business needs and financial goals.

When selecting between flat rate pricing and interchange plus pricing, consider the following practical tips:
Analyze Transaction Patterns: Examine your business’s transaction volume, average transaction size, and the types of credit cards your customers use. This analysis will guide your choice.
Customer Payment Habits: Understand your customers’ payment habits. Do they often use basic credit cards, or do premium cards play a significant role?
Flexibility Requirements: Assess how adaptable your pricing model needs to be. If your business experiences fluctuating transaction patterns, interchange plus pricing may offer more flexibility.
Compare the Fees: Take into consideration the difference in percentage charge, the difference in per transaction charges, and consider the monthly fee that comes with interchange plus accounts.
Certain industries benefit more from one pricing model over the other:
Retail: Retail businesses with few transactions, especially smaller ones, may find flat rate pricing more straightforward.
B2B and eCommerce: eCommerce businesses processing various credit card types often benefit from interchange plus pricing due to cost optimization opportunities.
When it comes to choosing between flat rate pricing and interchange plus pricing, it generally comes down to if you want the simplicity or lower fees rather than industry. If simplicity is paramount, flat rate works. If saving money is paramount, you’ll need to analyze your business. It’s imperative for merchants to evaluate their transaction patterns, customer base, and processing volume to determine which pricing model aligns best with their unique needs and financial goals.
In the realm of payment processing strategies, interchange plus pricing emerges as the superior choice for the majority of businesses, especially for businesses that process more than $200,000 per year. This model not only enables merchants to harness the benefits of variable interchange rates but also ensures that the payment processor’s profit margin remains minimal. Unless your monthly payment processing volume is relatively insignificant or your typical transaction size falls well below the average, interchange plus pricing should almost certainly be your preferred option when charting your business’s payment processing course.
