Introduction
In the rapidly evolving world of financial technology, companies like Stripe and Square have transformed how businesses accept payments. Their innovation lies in simplicity—businesses sign up, plug in, and start processing payments with minimal hassle. A significant selling point has been their flat-rate pricing, which offers predictability: a fixed percentage fee (e.g., 2.9%) plus a per-transaction fee (e.g., $0.30). At first glance, this seems like a fair, transparent approach. But beneath the surface, this pricing model may be costing businesses—especially small and medium-sized enterprises (SMEs)—far more than they realize.
Flat Fees: Simple, but Not Always Fair
The flat-rate fee model has undeniable appeal for its simplicity. Merchants know exactly what they’re paying per transaction, regardless of the customer’s payment method. But this “one-size-fits-all” approach fails to account for the nuances of payment processing, particularly when it comes to interchange fees.
Interchange fees are the variable costs set by credit card networks (like Visa and Mastercard) and paid to the card-issuing bank. These fees vary significantly based on factors such as:
• Card type: Debit cards typically have lower interchange fees than premium rewards credit cards.
• Transaction size: Smaller transactions often have higher percentage-based fees.
• Industry: Some industries, such as non-profits, qualify for lower rates.
• Risk level: Transactions deemed higher risk (e.g., online payments) incur higher fees.
Flat fees, however, disregard these variations. Merchants using Stripe or Square effectively subsidize customers using low-cost payment methods and overpay on transactions where interchange fees would otherwise be minimal.
Interchange-Plus Pricing: A Smarter Alternative
In contrast, the interchange-plus pricing model offers transparency and cost efficiency. With this model, merchants pay the actual interchange fee plus a fixed markup (e.g., interchange + 0.5%). This approach ensures merchants pay exactly what the transaction costs the payment processor, plus a reasonable service fee.
For example:
• A transaction involving a basic debit card may carry an interchange fee of 0.5% + $0.22. With interchange-plus pricing, the merchant might pay 1% + $0.22 total.
• Under Stripe or Square’s flat fee, the same transaction would cost 2.9% + $0.30—significantly more.
For businesses with thin margins, these differences can add up to thousands of dollars annually.
Who Loses the Most?
While flat fees may be manageable for micro-businesses or infrequent sellers, larger businesses and those processing high transaction volumes are disproportionately affected. Additionally:
• Non-profits: Often eligible for lower interchange rates, non-profits lose these savings when using flat-rate processors.
• High-volume merchants: Businesses processing large transaction volumes could save significantly with interchange-plus but instead pay inflated rates under flat-fee models.
• Low-ticket businesses: For smaller transactions, the per-transaction fee component ($0.30) becomes disproportionately burdensome.
Why Flat Fees Persist
So why do companies like Stripe and Square continue to offer flat fees? The answer lies in predictability—for both merchants and payment providers. Flat fees simplify accounting for merchants and create consistent, predictable revenue for payment companies. Additionally, many merchants may not have the time or expertise to explore more nuanced pricing models, making flat fees an easy sell.
What Merchants Can Do
1. Educate Themselves: Merchants should take the time to understand how payment processing fees are structured and evaluate whether flat fees or interchange-plus better suit their needs.
2. Shop Around: Many payment processors offer interchange-plus pricing with competitive rates and transparency. Providers like Adyen, Payline, and merchant-focused ISOs often cater to businesses seeking cost-efficient solutions.
3. Ask Questions: Businesses should inquire about hidden fees, markups, and flexibility when choosing a payment processor.
A Call for Transparency
While companies like Stripe and Square have revolutionized payments with their simplicity and innovation, their flat-rate pricing model may not always be in the best interest of the businesses they serve. As the payment landscape continues to evolve, it’s crucial for merchants to push for greater transparency and fairer pricing structures. Payment processors should focus on empowering their customers—not quietly overcharging them.
Flat fees may be convenient, but businesses deserve more than convenience. They deserve fairness. And it’s time for the industry to step up.
