Payment Routing: 7 Ways to Boost your Approval Rates

TL;DR

‍

U.S. merchants lose revenue every day due to payment failures, inconsistent success rates, and weak routing logic inside legacy payment stacks. Intelligent payment routing uses real-time data to route transactions to the payment processor most likely to approve them. It improves approval rates, reduces declines, increases cost efficiency, and works without changing your checkout. Below are seven ways routing boosts performance, based on real industry data and authoritative sources.

‍

Why U.S. Merchants Struggle With Payment Failures

‍

The U.S. payments landscape is large and fragmented. There are thousands of issuers, many acquirers, and fast-changing risk models. These moving parts often lead to payment failures, even when customers have funds and intend to pay.

‍

Reports like the LexisNexis True Cost of Fraud Study show that false declines cost U.S. merchants more than actual fraud losses. ACI Worldwide’s detailed breakdown of ecommerce trends in its Global Payments Report highlights how approval rates fluctuate by issuer, processor, and region. The Federal Reserve’s research on cross-border payments shows that routing choice affects both speed and completion rates.

‍

Many merchants try to fix this by modifying their checkout or switching processors. But an easier solution sits behind the scenes: payment routing.

‍

Payment routing works by deciding the best path for each payment in real time. It uses rules, data, machine learning, and processor performance insights to guide traffic to the acquirer most likely to approve each transaction. This is a powerful way to reduce declines, recover lost revenue, and stabilize payments without rebuilding your customer experience.

‍

The rest of this article explains how payment routing works and details seven ways U.S. merchants can increase approval rates without changing the checkout at all.

‍

What Is Payment Routing?

‍

At its core, payment routing is the engine that decides where each transaction goes. Instead of sending all payments to one processor, routing uses transaction data to select the best-performing provider at that moment.

‍

Routing considers:

‍

• Card network and BIN
• Issuer history
• Risk signals
• Transaction amount
• Payment method
• Customer country
• Processor performance
• Cost and fee structures

‍

Because U.S. processors perform unevenly throughout the day, routing has a big impact on success rates.

‍

There are several types of payment routing.

‍

Static routing

‍

Simple rules like “send all traffic to Processor A”. Easy, but often inefficient.

‍

Dynamic payment routing

‍

Uses live insights like latency, downtime, and approval rate patterns to pick the best processor.

‍

Smart payment routing

‍

Uses machine learning to predict which processor is most likely to approve each payment.

‍

Multi-acquirer routing

‍

Spreads payments across several processors for redundancy and optimization.

‍

Fallback routing

‍

Retries failed payments instantly with another processor to recover revenue.

‍

Together, these routing paths unlock higher performance and stronger reliability for U.S. merchants.

‍

Why Payment Routing Matters More in the U.S.

‍

Several factors make routing especially impactful for U.S. merchants.

‍

1. Issuer behavior varies widely

‍

McKinsey’s analysis of payment fraud and false declines in its report on digital payments resilience shows large differences in how issuers treat transactions. Some issuers prefer specific routing paths, while others respond to enriched data or domestic routing patterns.

‍

2. Acquirer performance changes constantly

‍

Holiday and sales-event reporting from PaymentsDive shows that processors often slow down or fail during peak times. A single slowdown can damage approval rates.

‍

3. False declines hit U.S. merchants especially hard

‍

False declines cost merchants billions each year. LexisNexis reports that for every $1 in fraud, merchants lose over $3 in decline fallout.

‍

4. More payment methods mean more routing complexity

‍

Wallets, ACH, BNPL, instant payouts, and alternative rails all affect routing paths.

‍

5. Cross-border payments are sensitive to routing

‍

The Federal Reserve’s research highlights that routing paths impact speed, fees, and approval outcomes.

‍

Because of these factors, intelligent payment routing is one of the most effective tools for improving approval rate and reducing payment failures in the U.S.

‍

7 Ways Payment Routing Increases Approval Rates Without Changing Your Checkout

‍

Below are the seven key routing strategies that help U.S. merchants improve performance fast.

‍

1. Fallback Routing Recovers Failed Transactions

‍

Many declines come from technical issues, not real customer problems. These include:

‍

• Processor downtime
• Network timeouts
• Latency spikes
• Soft risk declines
  
  

Fallback routing detects these events and instantly re-routes the transaction to a stronger processor. This recovers revenue that would otherwise disappear. It’s one of the quickest ways to reduce declines.

‍

2. BIN-Level Optimization Matches Transactions With the Right Processor

‍

Issuers have clear routing preferences. Visa’s data on authorization decline codes shows how issuers respond differently to transaction types and data elements.

‍

By studying BIN patterns, routing can:

‍

• Send Chase cards to the processor that approves them most
• Route Capital One cards to the processor with higher success rates
• Steer high-risk BINs to processors with better fraud balancing

‍

This targeted routing lifts success rates without higher fees.

‍

3. Real-Time Processor Monitoring Avoids Decline Spikes

‍

Processors do not perform consistently during the day. Approval rates rise and fall based on traffic load, system health, and risk tuning.

‍

TechCrunch has tracked several large-scale outages and slowdown incidents.

‍

Dynamic routing monitors:

‍

• Authorization success rates
• Latency
• Processor outages
• Risk-engine shifts

‍

When performance drops, routing shifts traffic away from trouble. This keeps approval rates steady during peak periods.

‍

4. Domestic and Cross-Border Routing Improves Cost and Performance

‍

Routing also chooses the most efficient geographic path. Domestic routing often results in higher approval rates and lower network fees. Cross-border routing, when not optimized, can increase declines.

‍

The Federal Reserve’s analysis of cross-border payment systems explains how routing choices affect performance.

‍

Routing engines can:

‍

• Prioritize domestic processors for U.S. cardholders
• Use data-rich processors for issuers that need more context
• Select the cheapest viable path for cost efficiency
• Reduce cross-border friction
  
  

This is especially important for merchants selling into or out of the U.S.

‍

5. Fraud-Aware Routing Reduces False Declines

‍

Fraud tools can block good customers. LexisNexis’ fraud study shows that false declines cost merchants more than completed fraud.

‍

Fraud-aware routing can:

‍

• Avoid unnecessary 3DS or step-up flows
• Pick processors with more balanced fraud models
• Use enriched transaction data to increase trust
• Reduce declines without raising fraud risk

‍

This creates a better customer experience and higher approval rate.

‍

6. Multi-Acquirer Routing Increases Stability and Reduces Transaction Costs

‍

Merchants that rely on one processor take on a single point of failure. Multi-acquirer routing protects against outages and gives merchants more control.

‍

With multi-acquirer routing, merchants can:

‍

• Reduce dependency on one provider
• Lower costs using cost-based routing
• Improve authorization outcomes
• Support more payment methods
• Achieve better stability during peak events
  ‍

‍

This is critical for enterprise-scale merchants handling large U.S. volumes.

‍

7. Issuer-Preference Routing Boosts Approval Rates for Specific Cards

‍

Issuer-preference routing uses data to detect which processor each issuer prefers. Data sources like Plaid help illustrate how different banks respond to different transaction types.

‍

Routing engines track patterns such as:

‍

• Which processors approve specific BINs
• Which issuers prefer domestic rails
• Which issuer categories trigger extra checks
  
  

This routing method is especially effective for:

‍

• Travel
• Gaming
• Ticketing
• Subscription billing
• Digital marketplaces

‍

These industries often see high issuer-driven declines. Routing helps offset that risk.

‍

Real Examples of How Intelligent Payment Routing Works

‍

Example 1: Latency spike

A processor slows down during a holiday promotion. Routing senses the slowdown and moves traffic to a faster processor.

‍

Example 2: Issuer decline wave

A major issuer tightens fraud rules. Routing shifts traffic to processors with enriched data flows.

‍

Example 3: Subscription retry

Soft declines from recurring payments are reattempted automatically through higher-performing processors.

‍

Example 4:Cross-border mismatch

Routing detects that a cardholder is international and selects a processor optimized for that region.
