Online payment processing – how does it work with PayU?

The payment processing journey in e-commerce

Consumers today enjoy a plethora of options to pay for goods and services online. Yet while the interface of online payments might seem basic to the end user, the online payments ecosystem is an ever-growing sphere. As money changes hands from customer to merchant, card networks, payment acquirers, alternative payment method providers, and many other players involved in the processing of online payments are communicating in a harmonious, behind-the-scenes dance that ensures the performance and continuous flow of transactions.

 

With transactions becoming more global and with more of them taking place online merchants must keep up with this complex playground – particularly the ins and outs of regulations and compliance requirements – all while trying to ensure the performance of their payment stack and make it as efficient as possible.

 

The following page outlines the individual role of every player in the online payment processing ecosystem, which ones are linked to your payment stack directly, and where each piece of the puzzle fits within the overall flow of online payments. Lastly, we explore where PayU comes into the equation and how we can help you maximize the efficiency of your online payments.

The lifecycle of online payments

 

The lifecycle of a transaction on its way to authorization starts with the user’s intent to purchase goods or services. In the user’s experience, the entire process lasts no more than a few seconds, yet the story behind the curtain involves multiple stages and each stage can impact the possibility of a transaction being approved or declined.
 
Online payment processing differs from ‘regular’ payment processing mainly in that online transactions are often performed between a consumer and a merchant which are placed in different geographical locations, and therefore the consumer’s identity cannot be verified by the merchant physically. This gap creates an added layer of complexity of online payment processing in comparison to POS (point-of-sale) transactions.
 

The key players in payments

 
If we simplify the process to its core, each online payment consists of the user, merchant, and the payment processing solutions that the merchant needs to interact with in order to approve/decline the transaction. In order to get paid, merchants need to integrate with a bank/payment acquirer whose job it is to hold on to the user’s payment on the merchant’s behalf –eventually depositing the funds into the merchant account once the transaction is authorized.
 
In addition to these basics, there are further players that help maintain the flow of sending and receiving payments. The payment processor is a service that works directly with the banks and card issuers, as well as any alternative payment methods. The payment gateway, meanwhile, links the shopping cart on your website to the payment processing network. Many payment services providers, including PayU, function as both a payment processor and a payment gateway.
 
Regardless of the level of integration along the way, all of the above players communicate with each other and in an optimal scenario the transaction is processed successfully without the user (or merchant) paying much attention. Yet as with most aspects of e-commerce, money is made and lost along the margins. This creates a plethora of opportunities for optimizing the payment flow, which helps merchants grow their customers and increase sales through the simple act of increasing the number of payments which are processed successfully.

Authorization and settlement in online payment processing

The step-by-step process – and how it can be optimized

The following summary looks at each step in the journey of online payment processing – and the ways in which merchants can optimize their payment flow to maximize revenue and conversions.

 

See the infographic above for a visual description of what happens behind the scenes during an online payment.

 

 

Part 1: Authorization

  • Each payment begins with the end customer – an online transaction is initiated when customers confirm a purchase after entering their payment information during checkout. Merchants can increase the number of successful checkouts (and therefore reduce the number of so-called ‘cart abandons’) by offering a wide variety of payment method options which are in line with the preferences of local customers.

 

  • Once a transaction is initiated, the customer’s payment information is then transmitted and tokenized via a payment gateway, which in turn passes the encrypted information on to the payment provider/acquirer.

 

  • The acquiring bank then captures the transaction and forwards the information to the customer’s card issuer (e.g. Visa, Mastercard) or alternative payment method provider.

 

  • The card issuer then sends a request for approval. Sometimes the user will need to verify their identity at this stage via a 2-step authentication process.

 

  • Next, the transaction receives a final ‘verdict’ whether it is approved or declined. The decision relies on multiple factors – but first the account needs to have the funds available to cover for the purchase. This process is therefore known as the authorization process, where if the transaction is indeed authorized, the cardholder’s funds are put on hold before they are transferred to the merchant account after all deductions (fees) are applied, in a subsequent process called the ‘settlement’.

 

 

Part 2: Settlement

  • After authorization is received, the settlement follows, during which funds enter the merchant account.

 

  • The acquiring bank where the merchant’s account is located sends the request to the card network for settlement, after which approved transactions reach the issuing bank, where the issuer sends the funds to the merchant’s acquiring bank, deducting the interchange fee from the overall sum. The issuing bank then bills the cardholder for the transaction, and the payment is complete.

 

  • Although the settlement process is straightforward, as with the other steps there are countless places where the payment can go wrong or where the process can be optimized. Throughout the entire chain of online payment processing, each hand that touches the transaction is taking a cut of the merchant’s revenue by charging fees that can vary depending on the bank/payment acquirer. The job of a good online payment processor is to maximize approval rates and minimize unnecessary fees.

 

 

Tools to battle false declines

One of the biggest scourges for any merchant accepting online payments is that of ‘false declines’ – transactions which should not have any reason to be declined but are declined anyway, generally because they trigger one of many possible fraud filters which are typically determined by an algorithm.

 

There are many reasons for fraud filters to raise a red flag and trigger a false decline, from the shopper’s IP location, to the value of the transaction, to inconsistencies between the shipping and billing addresses (plus many more).

 

One of the ways that payment processors can help merchants to maximize the value of their online transactions is through solutions like PayU’s Instant Retry Feature, which allows merchants to configure their own set of custom routing rules that can attempt payments again in real-time using a different payment acquirer, in the event that a transaction is declined by the first provider.

Payment processing FAQs

What are card networks?

Card networks are card brands such as Visa, Mastercard, American Express, etc., which have a regulatory role in the ecosystem, and they oversee the flow of transactions performed by users.

Who are the card issuers?

Issuers are entities that issue credit and debit cards to consumers on behalf of the card networks (e.g. Visa, Mastercard). The issuers are usually banks, but not necessarily. Since issuers are the ones who assume risk if a customer is unable to pay, the authorization process cannot be complete without their assurance that the customer has the funds to pay for the transaction.

Who are the acquirers?

Acquirers play a key role in the payment processing flow. They are the bodies that process payments on behalf of merchants, but they can also function as payment processors or as an Independent Sales Organizations (ISO), which (in the latter case) means that they also function as an acquiring bank. The acquirer oversees the passing of the merchant’s transaction to card networks/alternative payment methods, in order to complete the payment.

What is a chargeback?

A chargeback is a procedure whereby a cardholder or the cardholder’s bank disputes transactions to payment cards. A disputed payment card transaction is returned to the acquirer/ISO/MSP for reimbursement.

What are Card Not Present (CNP) transactions?

Card Not Present (or CNP) transactions are when payments are performed where the cardholder is not physically present or cannot physically present the card for a merchant’s visual examination at the time that an order is placed. CNP transactions encompass both the “analog” (mail-order transactions or payments made via phone) as well as the digital (online payments).

What are cross-border payments?

Cross-border payments are payments performed between accounts in different countries – from the payment system of the country of origin through a payment processing provider to the payment system of the country of receipt.

How does PayU protect online payments?

Payment performed via the PayU Hub are tokenized, receiving an ID which conceals the original data. That way, your customers can rest assured that their personal data and card information is protected by the highest possible standards. As a merchant, tokenization helps to lower your PCI scope and adhere to regulatory requirements when it comes to processing a customer’s personal payment information.
