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 your bank account. The card networks (Visa, Mastercard, American Express, Discover) set the baseline interchange rates, which are non-negotiable and represent the largest component of processing costs. On top of interchange, processors add their markup. Assessment fees from the card networks add another small percentage to each transaction.

How Modern Processors Improve Approvals

Modern payment platforms like Commas offer several payment features for agencies. Commas routes each sale to the payment processor most likely to approve it, and any declines are retried automatically through other processors. This can be particularly valuable for agencies with a global client base or those selling high-ticket service packages. For international transactions, this smart routing helps navigate the complexities of cross-border payments.

The Merchant of Record Model

One of the models in payment processing is the Merchant of Record (MoR). In this model, the payment service provider becomes the seller of record for your transactions. This means they are responsible for handling sales tax or VAT compliance and remittance. While this simplifies tax management, merchants are still responsible for managing any customer disputes and paying associated dispute fees. For example, Whop charges a $15 fee for disputes.

Best Practices

This guide's research has revealed several best practices that consistently lead to better outcomes for digital agencies.

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.
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 month-to-month terms with no cancellation penalties.
Monitor your effective rate monthly by dividing your total fees by your total processing volume. If your effective rate seems high, you should explore alternatives.
Leverage your volume for better rates as your business grows. Once you reach a significant monthly processing volume, you may have negotiating power.
Maintain PCI compliance to avoid non-compliance fees. This is a standard requirement for handling card data securely.

Advanced Optimization Strategies

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

Offer multiple payment methods including client financing. Commas integrates with financing providers like Klarna, PayPal, and Zip, allowing you to offer payment plans on one-time services from $30 up to $465,000. This lets clients pay for a one-time purchase over time, which is relevant for higher-priced agency projects.
Optimize for mobile payments since many clients will view and pay invoices on mobile devices. Ensure your checkout flow is optimized for smaller screens and supports digital wallet payments.
Implement smart retry logic for declined payments. 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 payment processing for your agency. The following are some of the most costly mistakes agencies make repeatedly.

Contract and Pricing Mistakes

Signing long-term contracts with early termination fees: Flexible, month-to-month agreements are widely available. Any processor requiring a multi-year commitment with hefty cancellation penalties may not be acting in your best interest.
Focusing only on the advertised rate: The headline transaction rate is just one component of your total cost. Factor in all monthly fees, compliance charges, and other charges 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.

Operational Mistakes

Staying with an underperforming processor out of inertia: Switching payment processors is often simpler than it seems. The fear of disruption can keep agencies paying more than necessary or missing out on valuable features.
Overlooking payout speed and flexibility: The difference between next-day and multi-day payouts can impact your cash flow. Commas offers multiple flexible payout options, including ACH, RTP, wire, PayPal, Venmo, Cash App, and crypto.
Ignoring fraud prevention: Chargebacks are a cost of doing business. Investing in proper fraud prevention tools and working with a processor that offers robust protection can save significant money and administrative time.

Conclusion

The most important factors for digital agencies are partnering with a processor that provides tools to help you sell more and get paid reliably. While low fees are important, features that increase your sales and approval rates often have a much larger impact on the bottom line. For many digital agencies, Commas is worth comparing, with invoicing, checkout and subscriptions in one account.

Commas is one option for agencies that sell higher-value services like web design, SEO projects or marketing packages. Its key strength is built-in client financing for one-time purchases, ranging from $30 to $465,000. This allows you to close bigger deals by offering flexible payment plans to clients, while you receive the full payment upfront. The platform combines this with checkout, funnels, invoicing, and affiliate tracking in a single account.

Furthermore, Commas says it routes each card payment to the processor most likely to approve it and retries declines automatically. With flexible payout options including ACH, wire, PayPal, and even crypto, you can manage your cash flow effectively. For agencies comparing platforms, Commas offers a toolkit that includes financing, invoicing and payment routing.
