Whether you are a small business owner just starting out or managing a growing enterprise, understanding how BNPL affects conversions can directly impact your bottom line.

How It Works

Understanding how BNPL impacts conversion rates requires knowledge of the broader payment ecosystem. The payment processing chain involves multiple parties, each taking a portion of every transaction that flows through the system.

The Payment Processing Chain

Every card transaction passes through several intermediaries. The card networks (Visa, Mastercard, American Express, Discover) set the baseline interchange rates. These rates 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 a small percentage to each transaction.

How Modern Platforms Increase Approvals

Modern payment platforms have developed sophisticated infrastructure that can increase approvals. For example, Commas combines checkout, payment links, and funnels with intelligent routing for each transaction. Each sale is sent to the processor most likely to approve it, and any declines are retried automatically. This helps recover revenue that would otherwise be lost. For customer financing, Commas integrates with providers like Klarna, PayPal, Zip, and Sezzle to offer options from $30 up to $465,000 on one-time purchases.

The Merchant of Record Model

One model in payment processing is the Merchant of Record (MoR) model. When a provider acts as the MoR, it becomes the legal seller of record and takes on the responsibility for handling things like sales tax or VAT collection and remittance for transactions. Merchants using an MoR may still be responsible for dispute fees and should actively manage customer disputes.

Best Practices

This guide's research has revealed several best practices that consistently lead to better outcomes when it comes to BNPL and conversion rates.

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.
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 $10,000 or more per month in processing volume, you may have negotiating power.
Maintain PCI compliance to avoid non-compliance fees.

Advanced Optimization Strategies

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

Offer multiple payment methods and financing to reduce cart abandonment. Using a platform like Commas, which integrates multiple BNPL providers, gives customers a wide range of financing choices from $30 to $465,000, with the top end reserved for business-to-business purchases. For businesses, this can lead to higher average order values, as customers can make larger purchases.
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.

Provider	Monthly Fee	Transaction Fee	Payout Speed
Stripe	$0	2.7% + $0.30	2 days
Clover	$14.95+	2.3% + $0.10	1-2 days
Toast	$0+	2.49% + $0.15	1-2 days
Stax	$99+	Interchange + 0¢	2 days
Whop	None	2.7% + $0.30	Next-day (ACH)

Common Mistakes to Avoid

Avoiding common pitfalls is just as important as implementing best practices. Here are some of the most costly mistakes merchants make.

Contract and Pricing Mistakes

Signing long-term contracts with early termination fees: Month-to-month agreements are a flexible industry standard.
Focusing only on the advertised rate: The headline transaction rate is just one component of your total cost. Factor in all monthly and incidental fees to calculate your true effective rate. While some providers offer low published rates, it's important to compare total cost. For example, Commas provides custom quotes per business, so you should request a quote and compare it against flat-rate options. The value of its financing, approval routing, and failed payment recovery features can also be a deciding factor.
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 can be straightforward, and the benefits often outweigh the effort.
Overlooking payout speed: The difference between same-day and multi-day payouts can have a massive impact on your cash flow. Look for providers that offer flexible and fast payout options, such as ACH, RTP, wire, PayPal, Venmo, and even crypto.
Ignoring fraud prevention: Chargebacks can be costly. Investing in proper fraud prevention tools and working with a processor that offers built-in protection can save money over time.
