One of the most important—and often overlooked—aspects of managing your business operations is negotiating the right pricing with your payment service provider (PSP). Regardless of your industry, finding a PSP to process your credit and debit card transactions is just the beginning. We’ve worked with over 700 merchants, and 9.9 times out of 10 (real stat from our CEO) they were overpaying their PSP and didn’t know it. Negotiating and minimizing PSP fees is a core component of payment optimization—and one of the most impactful ways to manage payment costs. In this post, we’ll share four ways to strengthen your negotiation strategy and reduce costs.
What is a Payment Service Provider (PSP)?
A payment service provider (PSP) is a company that facilitates the transfer of funds between you and your customers—whether those payments are made via debit card, credit card, ACH transfer, or digital wallet. Acting as the middleman between merchants, customers, and banks, a PSP enables businesses to start accepting payments quickly, without the need to set up a traditional merchant account.
They provide the infrastructure to move money, ensure transactions are secure, maintain compliance standards, and offer built-in tools like payment gateways and dashboards. From onboarding to settlement, they handle much of the heavy lifting behind the scenes.
PSPs also play a key role in your broader payment strategy. From optimizing approval rates to managing risk and ensuring regulatory compliance, your PSP has a direct impact on the efficiency and profitability of your payment operations. Providers like Stripe, Square, Toast, and Stax are common examples, each offering slightly different tools and pricing models depending on your business needs.
Because of this convenience, many merchants rely heavily on their PSP—not just to process transactions, but to route them efficiently and secure the most cost-effective rates. Unfortunately, that trust is often misplaced. Without visibility into pricing or control over routing, merchants can end up paying far more than they should.
Common Pricing Methodologies
Understanding how your PSP charges for processing payments is one of the most critical steps in managing payment costs. While many merchants focus on the flat rate they see on paper, the actual fee structure can be far more complex—and in many cases, more expensive than necessary.
Some PSPs charge a flat fee per transaction, while others use a percentage of the transaction value. On top of those core fees, merchants may also be responsible for setup fees, monthly service fees, chargeback fees, and currency conversion fees. And we can’t forget about potential hidden fees—like cross-border fees or authorization fees—that are often buried in your monthly statement and easy to overlook.
Most PSPs use one of two main pricing models:
- Blended Pricing Model
This approach combines a fixed gateway fee with a variable processing fee. While it may seem simpler, it lacks transparency. The variable fee often includes the PSP’s markup—but it’s not always clear how much of it goes to actual processing costs vs. margin. Because of this, many merchants unknowingly pay more than they would under a different model.
Interchange Plus Pricing Model
- This model breaks out the fees more clearly. Merchants are charged a gateway fee, plus the actual interchange fee set by the card networks (like Visa or Mastercard), scheme fees, and a separate acquirer markup. Each party—network, processor, and acquirer—takes a small fee for their role in the transaction. While this model may appear more complex on the surface, it gives you visibility into where your money is going and can be more cost-effective in the long run.
Many merchants default to blended pricing because it looks simple and predictable. But in our experience, that simplicity often comes at a cost.
Negotiating With Your PSP
If your goal is to optimize payments and gain better control over fees, you may be wondering: What can I actually do to ensure I’m paying the most optimal rates? Here are four actions we encourage every merchant to take when negotiating with their PSP.
1.Review Your Current Contract
Many merchants assume their PSP is being fully transparent about pricing—but that’s often not the case. It’s not uncommon for providers to bundle fees in a way that obscures where your money is actually going. That’s why one of the most important steps you can take is to thoroughly review your current agreement.
We strongly encourage every merchant to request a breakdown of interchange plus pricing. This level of transparency allows you to see exactly how much is going to the card networks and issuing banks (interchange), versus what’s being added on by your processor (markup). Without this detail, it’s nearly impossible to understand whether your rates are fair—or how much room you have to negotiate.
By identifying how much of your total processing cost is tied to interchange fees (which are non-negotiable) versus your PSP’s margin (which is negotiable), you can make a more informed case for better terms. It’s your money—you deserve to know exactly where it’s going.
2.Benchmark Your Pricing Against Industry Peers
Now that you are fully aware of how much you’re paying and where your money is going, we encourage you to compare it to your peers. When it comes to negotiating with your PSP, you come to the table with a stronger hand if you know what others in your industry are paying. Without this context, it’s easy to accept rates that sound reasonable—but may be well above market standards.
There are a few ways to gather this insight:
- Do Your Own Research: While PSP pricing isn’t always transparent, you can often find ranges by looking at publicly available fee structures, industry forums, and merchant case studies. Just keep in mind that pricing can vary based on transaction volume, average ticket size, industry type (MCC), and geography—so look for examples that match your business profile as closely as possible.
- Talk to Your Peers: If you’re part of an industry group or merchant network, don’t be afraid to ask other professionals what they’re paying and who they’re using. Many merchants are more open than you’d think, especially if it helps everyone negotiate better terms.
- Work with a Consultant: Payment consultants have visibility into what similar merchants are paying across processors, industries, and transaction types. That allows us to benchmark your pricing against real, recent data—and help you identify where you’re overpaying.
Benchmarking gives you leverage. Armed with real-world comparisons, you can challenge inflated rates, spot hidden markups, and negotiate more confidently.
3.Avoid Long-Term Contracts
Your PSP benefits when you lock into a long-term agreement—but that doesn’t mean it’s what’s best for your business. While multi-year contracts may come with the promise of stable pricing or waived setup fees, they often limit your flexibility and leave you stuck with unfavorable terms.
We recommend negotiating shorter contract lengths whenever possible. In our experience, many merchants sign 5 years agreements, but we would encourage you to take a 3 year agreement (or less) as it gives you the freedom to reassess if your business grows, if your processing rates increase, or if your PSP’s service isn’t meeting expectations. It also keeps your provider on their toes—knowing you can walk away gives you more leverage throughout the relationship.
The payments landscape changes quickly, and your contract should give you the ability to adapt. Don’t give that power away too easily.
4.Consider a Multi-PSP Strategy
Relying on a single PSP might seem like the simpler route—but it can leave you vulnerable. If your only processor experiences downtime, rate increases, or approval rate issues, your business has no backup. You’re also limited to one pricing structure, one set of capabilities, and one relationship—regardless of whether it continues to meet your evolving needs.
That’s why a multi-PSP strategy is worth considering, especially for enterprise merchants. Diversifying your processors gives you options: to route transactions more efficiently, test new markets, and negotiate better rates by creating internal competition. It also adds resilience to your payment operations, helping you avoid disruptions that can impact revenue and customer experience.
