From changing regulations to cross-border fees, there are many payment processing challenges that can impact your acceptance rates, overall costs, and network reliability. Smart payment routing is essential for facing these obstacles. 

Intelligent payment routing allows you to optimize your payment routing so that transactions go to the best possible provider. The routing considers important signals, such as historical success, geographic location, and the card network, in order to make sure the payment goes to the ideal payment gateway. Through this type of change, you can lower your overall costs without making any updates to your products, services, or customer experience.

To learn more about how a smart routing payment gateway works, read on.

TL;DR

  • With the help of real-time data, smart payment routing can send payments to the best-suited payment processor.
  • Smart routing replaces static rules and single points of failure with dynamic routing and data-driven decisions.
  • Intelligent routing tracks signals, such as geographic locations, processing fees, latency, approval rates, and historical data.
  • When routing is implemented poorly, it can lead to more frequent declines, higher fees, and messy reconciliation processes.
  • Through the best routing, you can improve your revenue stream, enhance your customer experience, and prevent declined transactions
  • By routing soft declines through a backup processor, you can avoid the inconvenience of failed transactions.

By using intelligent routing, companies can improve their approval rates, reduce how much they spend on fees, and achieve a better level of reliability.

What Is Smart Payment Routing?

Smart payment routing is when payments are routed through different processors based on the rules you choose. These decisions are made using hard data, so the most effective route is selected.

Let’s look at how this works in practice.

Imagine you have two processors. Processor 1 has excellent fraud detection, low processing costs, and primarily serves your local region. Meanwhile, Processor 2 is known for its global coverage and low cross-border fees.

With this information, you can create different rules.

  • Rule 1: If the card is from outside of your local area, you use Processor 2 because of its better global coverage and lower cross-border fees.
  • Rule 2: For cards that are in your local region, opt for Processor 1 because of its low processing costs for local cards.

These aren’t the only rules you can choose. For example, you can select rules that maximize uptime, reduce costs, ensure better fraud prevention, or pick processors based on your geography. How you optimize your routing all depends on your end goal.

With intelligent payment routing, you don’t have to personally know if one processor is faster or more reliable than another. Smart routing incorporates A/B testing, so your system can test which processor returns the best results over time.

How Intelligent Routing Works To Boost Payment Performance

While our example was fixed and rule-based, modern routing is never static. The routing system is constantly testing different routes to determine which payment gateways and processors will be the most successful. Through advanced routing strategies, merchants can enjoy a few key advantages.

Fewer Payment Failures

Through advanced routing, you can prevent payment failures. If one gateway is experiencing latency or an outage, your system can redirect payments in real time. Similarly, you can avoid technical declines and underperforming routes. As a result, your company can bring in more revenue and experience fewer instances of failed payments.

Higher Authorization and Approval Rates

Authorization and approval rates are often used interchangeably in the industry. For clarity, we typically refer to authorization rates as the number of transactions approved by an issuing bank. Meanwhile, approval rates represent the percentage of orders that pass fraud, risk, and bank checks to get fully processed. Authorization occurs at the beginning of payment processing, while approvals complete the process.

With smart routing, transactions aren’t just sent to the payment processor that has the highest approval and authorization rates. Instead, your system considers which processor has the highest rates of approval for each specific kind of transaction.

Lower Processing Costs

Through intelligent routing, your transactions can be sent to the lowest cost option without sacrificing your approval rates and reliability. Cross-border fees, conversion rates, and other fee types can vary based on the transaction, which makes intelligent payment optimization even more important.

Improved Reliability During Provider Incidents

Partial degradations, outages, and other problems can occur from time to time. Because of this, you can’t afford to have a static routing system. Smart payment routing allows you to send transactions to backup routes as soon as a provider incident is detected.

What Are Routing Decisions Based On? 

When routing decisions are made, they’re based on historical data, payment routing signals, and transaction information. This data changes in real time, so modern routing engines must be dynamic and capable of adjusting as the routing pathways change.

To get a better understanding of how these decisions are made, let’s look at common payment routing strategies and what different routing signals mean.

Top Payment Routing Strategies 

Through smart payment routing and advanced payment orchestration, you can optimize your payment systems. There are a few common strategies that companies use to improve their payment routing.

  • Performance-Based Routing: This style of routing is used to optimize success rates based on historical data for each route.
  • Backup Routing: Redundancies are typically created in case one route fails or experiences higher latency.
  • Geo-Optimized Routing: This routing strategy targets different routes based on the geographic region, reducing cross-border fees.
  • Method-Based Routing: With this approach, the route is chosen based on the type of payment used.
  • Low-Cost Routing: This routing strategy involves selecting the most cost-effective route that also fulfills minimum approval requirements.
  • Retry Routing: When a specific payment fails due to a soft decline, this strategy uses backup options to avoid another failed transaction.

Common Payment Routing Signals and What They Mean

Payment routing signals are real-time data points that are used to optimize the routing process. Basically, they are inputs that your payment systems look at to determine how payments should be routed. 

When a specific signal or condition is detected, it triggers a specific routing action. The overall goal is to improve approval rates, lower costs, or boost reliability.

Routing factor / signalWhat HappensWhy It Happens
Card NetworkThe best network or path is chosen for the transaction, based on which card type is involved.Higher approvals
CurrencyTransactions are routed to acquirers that support the local currency, so conversion fees are avoided.Lower costs
GeographyTo prevent cross-border declines, the transaction is routed to a regional or local acquirer based on its geographic location.Higher approvals
Interchange and Processing FeesThe payment is routed through low-cost networks, so merchants pay lower fees while still obtaining a high approval rate.Lower cost
Issuer Response HistoryThe routing engine sends the transaction to the acquirer or gateway with the highest approval record.Higher approvals
Latency (Acquirer or Gateway)Transactions are routed away from slow acquirers or gateways.Better reliability
Payment MethodRoutes are chosen according to their performance for different kinds of payment methods, such as credit cards and prepaid cards.Higher approvals
Real-Time AvailabilityThe transaction is routed to a backup route if its initial route fails.Better reliability
Retry EligibilityWhen a transaction receives a soft decline, it is rerouted through a backup network or acquirer.Higher approvals
Time of Day or WeekCertain routes are avoided during peak congestion days or times.Better reliability
Transaction AmountAn acquirer or route is picked based on the total value of the transaction.Higher approvals

When Is Smart Routing Worth the Effort? 

Intelligent payment routing allows you to maximize your revenue and optimize your payment systems. This type of approach is more likely to be worth the effort when it demonstrably increases your revenue, lowers your costs, and boosts your approval rates. It is especially effective for international merchants that need to route cross-border transactions.

While smart routing offers better results for some merchants than others, every merchant can benefit in some way. Intelligent routing offers convenient payment processing across different geographic regions, better resilience, and lower transaction costs. Plus, small gains in your approval rates can result in appreciable revenue increases.

Common Routing Pitfalls To Avoid

When adopting smart routing techniques, there are a few common pitfalls you should watch out for.

Over-Retrying

If you retry a transaction too many times, it can result in a worse cardholder experience and serve as a red flag with your issuer. The repeated attempts may look like fraud or abuse. To avoid this issue, it’s essential to limit the number of retries after a soft decline.

Creating False Declines

When you set up overly aggressive routing rules, it can increase the likelihood of false declines. To avoid this, it’s important to set routing rules that don’t filter out transactions excessively.

Messy Reporting and Reconciliation

Routing across different networks and processors creates a more complicated reconciliation process and paper trail. Unified reporting is essential for making sure all of the data is compiled into one cohesive record.

Only Optimizing for Approvals

While maximizing approval rates is important, it isn’t the only routing goal you should focus on. If you focus entirely on approvals, you may be routing transactions through processors that have higher costs, increased latency rates, and more risk.

Static Routing Rules 

Static routing rules don’t adapt to day-by-day and minute-by-minute changes. With dynamic, smart routing, you can learn from outcomes and adjust. This ensures that each routing decision is improved as the processing environment changes.

Inadequate Monitoring

Even with an intelligent routing system, you shouldn’t just adjust your system settings and forget about it. As you receive data about how your routing rules are working out, it’s important to make modifications. Good data tracking and monitoring ensure the best level of payment optimization.

Exchanging Low Costs for Reliability

Low-cost routing is important, but it isn’t the only factor in determining the right payment processor. If you only route to the cheapest provider, it can result in more failures, downtime, and timeouts. Instead, you need to make sure low-cost providers meet a minimum standard for reliability and approval rates.
