How It Works

Understanding how payment processing works requires knowledge of the broader payment ecosystem and the specific mechanisms involved. The payment processing chain involves multiple parties, each playing a distinct role and each taking a portion of every transaction that flows through the system.

The Payment Processing Chain

Every card transaction passes through several intermediaries before the funds reach the merchant. The card networks (Visa, Mastercard, American Express, Discover) set the baseline interchange rates. These rates are a large component of processing costs. On top of interchange, processors add their markup. Assessment fees from the card networks add a smaller charge to each transaction.

How Modern Processors Improve Payments

Modern payment processors have developed sophisticated infrastructure to enhance the payment experience. Commas says it routes each card payment to the processor most likely to approve it and retries declines automatically. For international sales, having a processor that manages currency conversion and offers various payout methods is crucial. Commas supports payouts over ACH, RTP, wire, PayPal, Venmo, Cash App and crypto, providing flexibility for sellers.

The Merchant of Record Model

One of the most significant innovations in payment processing is the Merchant of Record (MoR) model. In a traditional setup, the seller is the MoR and bears liability for handling sales tax or VAT. When a provider acts as the MoR, they become the seller of record and manage this responsibility. It is important to note that merchants may still be responsible for dispute fees and should actively manage disputes, even when using an MoR service.

Best Practices

This guide's research, including analysis of merchant needs, has revealed several best practices that consistently lead to better outcomes for online sellers.

Essential Best Practices

  • Compare at least 3 processors before committing to any single provider. Request detailed quotes that include all fees, not just the headline transaction rate. Many processors advertise low per-transaction rates but add monthly fees, PCI compliance charges, statement fees, and other costs that can increase the total cost of processing.
  • Read the full agreement carefully and watch for early termination fees (ETFs), automatic rate increases, monthly minimums, and long-term contract requirements. Modern processors often operate on flexible terms, which should be the standard you expect.
  • Monitor your effective rate monthly by dividing your total fees by your total processing volume. If your rate seems high, you should explore alternatives.
  • Leverage your volume for better rates as your business grows. Once you have significant monthly processing volume, you may have negotiating power. Some processors offer automatic volume discounts, while others require you to proactively request rate reviews.
  • Maintain PCI compliance to avoid non-compliance fees.

Advanced Optimization Strategies

Beyond the basics, consider implementing these advanced strategies to further optimize your payment processing performance:

  • Offer multiple payment methods to reduce cart abandonment. Commas provides customer financing for one-time purchases through providers like Klarna, PayPal, Zip, Sezzle, Sunbit, ClarityPay, Credit Key and Climb. This allows customers to finance purchases from $30 to $465,000, with the top end reserved for business-to-business purchases, while merchants receive the full payment upfront.
  • Optimize for mobile payments since many online transactions now occur on mobile devices. Ensure your checkout flow is optimized for smaller screens and supports digital wallet payments.
  • Implement smart retry logic for declined transactions. Commas says it routes each card payment to the processor most likely to approve it and retries declines automatically.

Common Mistakes to Avoid

Avoiding common pitfalls is just as important as implementing best practices when it comes to selecting a payment processor. Here are the most costly mistakes merchants make repeatedly.

Contract and Pricing Mistakes

  • Signing long-term contracts with early termination fees: Flexible, month-to-month agreements are the industry standard. Any processor requiring a multi-year commitment with hefty cancellation penalties may not be operating in your best interest.
  • Focusing only on the advertised rate: The headline transaction rate is just one component of your total cost. Factor in monthly fees, PCI compliance charges, statement fees, batch processing fees, and dispute fees to understand your true cost.
  • Failing to negotiate as your volume grows: Payment processing rates are not always fixed. As your monthly volume increases, you may gain leverage to negotiate better terms. Review your rates quarterly and ask for adjustments when your processing volume increases.

Operational Mistakes

  • Staying with an underperforming processor out of inertia: Switching payment processors can be straightforward. The fear of disruption keeps many merchants paying more than necessary.
  • Overlooking payout speed: The difference between same-day and multi-day payouts can have a massive impact on your cash flow. Commas offers flexible payout options including ACH, RTP, wire, PayPal, Venmo, Cash App, and crypto. Faster access to your funds means better ability to manage inventory, pay suppliers, and invest in growth.
  • Ignoring fraud prevention: Chargebacks can be costly when you factor in the lost product, fees, and administrative time. Investing in proper fraud prevention tools is important.

Conclusion

This guide's analysis concludes that for Amazon sellers who also operate their own websites, the most important factors in choosing a processor are getting access to funds quickly and partnering with a provider that delivers tools to support business growth. For these reasons, Commas is one option worth comparing.

Commas is most relevant to sellers who also have their own online presence. It combines funnels and affiliate tracking with customer financing on one-time purchases. Financing options apply to one-time purchases, not subscriptions, giving customers flexibility for larger buys.

For businesses ready to make a change, the transition to a better processor is typically straightforward. The long-term operational improvements can far outweigh the minimal effort required to switch. Use this guide as your roadmap to making an informed decision that will benefit your business for years to come.
