eCommerce Payment Processing: What is it, how is it done, and what are the best practices? 

E-commerce is an integral part of human life today. Fifteen years ago, shopping meant visiting a brick-and-mortar store, exploring the options, and experiencing the products firsthand before purchasing by paying cash or completing a credit card payment. But today, shopping usually involves browsing products on an e-commerce site, experiencing them virtually, making a digital payment, and completing the purchase online. This transformation has been made possible by the reliability and secure nature of the e-commerce payment process. 

The evolution of e-commerce payment methods has been pivotal in reshaping consumer behavior and propelling the online retail revolution.Secure payment gateways and advanced payment processors brought the integration of diverse payment options, including credit card payments, into the fabric of online transactions. They offered convenience and security, gradually built customers’ trust, drastically improved customer engagement with e-commerce businesses, and transformed the e-commerce landscape. 

Through the years, payment processing has become more reliable, as establishing secure channels for accepting payments and safeguarding customer information through merchant accounts and payment service providers gained priority. The more seamless the payment processors integrated with the e-commerce ecosystem, the easier the transactions became. This symbiotic relationship between cutting-edge payment methods and the e-commerce industry has catalyzed the digital shopping era. 

This article explores the payment process, its steps, the different payment processes, and the best practices in e-commerce payment integration. 

How does e-commerce payment processing work? 

The e-commerce payment processing system involves multiple steps, including: 

1. Product Selection 

The customers browse the online store, sift through numerous options, select the right products that suit their needs and price range, add to the cart, and proceed to checkout. It is the initial phase of the shopping journey. It culminates in navigating to the payment gateway, where the customer completes the online payment.  

2. Input of Payment Information 

The front end of the payment page lets customers enter their payment information, including credit/debit card details or digital wallet credentials, billing address, contact information, and other relevant data, and initiate the checkout process. 

3. Encryption and Security 

The back end takes over the checkout process, and the payment information is encrypted to ensure data security. Without encryption, there is a danger of theft of sensitive personal and financial data. So, this encryption is a critical measure to protect customer details from unauthorized access during transmission. 

4. Payment Gateway Authorization 

The payment gateway integrated with the back end receives the encrypted payment data. The payment gateway is usually a third-party integration offered by financial institutions and digital wallet services. It acts as an intermediary between the e-commerce platform and these financial institutions. It authorizes the transaction by verifying the validity of the payment details and checking if the customer has sufficient funds in the account/wallet. 

5. Communication with Payment Processor 

The payment gateway communicates with the payment processor. The payment processor is usually a financial institution or a third-party service responsible for handling the actual fund transfer. 

6. Authorization from Issuing Bank/Wallet Service 

Once the payment information is verified, the payment processor sends the transaction details to the customer’s credit card issuer/financial institution/digital wallet service provider for authorization. If the payment details are approved, the issuing bank/financial institution/digital wallet service will confirm the availability of funds in the customer’s account for the transaction and return an authorization code. 

7. Transaction Approval 

Upon receiving the authorization code, the payment processor informs the transaction status to the payment gateway. If approved, the payment gateway notifies the e-commerce platform that the transaction is successful, thus completing the transaction. 

8. Completion of Sale 

Completion of the transaction does not automatically mean the completion of the sale. Your e-commerce store receives the transaction authorization status and proceeds to complete the sale. Upon completing the sale, the customer receives an order confirmation, and the order details are generated in the back end for the reference and follow-up of those who manage the e-commerce store. Simultaneously, the fund transfer from the customer’s account to the merchant’s bank account is initiated. 

9. Settlement and Payout 

The payment processor initiates the settlement process, transferring the funds from the merchant’s bank to the merchant’s account. This process completes the financial aspect of the transaction. 

10. Record-keeping and Reporting 

Financial transactions must be reported to the customer and the merchant to confirm if the transaction was successful. Maintaining these reports is vital because some orders might get canceled, and those customers might return the products, necessitating a refund. There could even be disputes between the two parties regarding the payment. During such events, there is a need to reconcile and verify these financial records and take the right action. So, it is imperative to maintain comprehensive records of the transactions. 

What are e-commerce payment methods? 

E-commerce payment methods refer to the ways in which customers can pay for products or services when shopping online. These methods have evolved to offer flexibility and convenience. Some of the most popular e-commerce payment methods include: 

1. Credit Cards 

Credit card payment is one of the most widely used e-commerce payment methods. Customers who choose this payment method can purchase using credit cards like Visa, MasterCard, American Express, or Discover. 

2. Debit Cards 

Debit cards are similar to credit cards. But while credit cards allow customers to purchase on credit and pay later, debit cards deduct funds directly from the customer’s bank account, providing a convenient and immediate payment option. 

3. Digital Wallets 

Digital wallets allow users to store their card information digitally in an app and use it for quick and easy online payments instead of filling in the payment information manually. Many digital wallets let users add digital currency from the cards for easier and more convenient online purchases. They also let users add digital Services like PayPal, Apple Pay, Google Pay, etc. Digital wallets are projected to be the preferred payment method for 51.7% of global e-commerce purchases in 2024. 

4. Bank Transfers 

Customers can initiate payments directly from their bank accounts using online banking services or Automated Clearing House (ACH) transfers. 

5. Cryptocurrencies 

Some e-commerce platforms accept cryptocurrencies like Bitcoin or Ethereum as a form of payment, providing an option for users who prefer decentralized digital currencies. 

6. Cash on Delivery (COD) 

When Cash On Delivery method is selected, the amount is not collected upfront while ordering. Usually, the delivery personnel collect the payment at the time of delivery. This method offers a more traditional and secure payment system. 

It builds mutual trust among the customers and your e-commerce business, as the customers get to see how you promptly deliver the products at their doorsteps even when they have not paid upfront, and you, as an e-commerce business, show enormous faith in the customer to pay upon delivery without fail. This builds mutual understanding and trust. 

7. Buy Now, Pay Later (BNPL)/Installments 

Numerous service providers, including Afterpay, Klarna, Amazon, banks, and other financial institutions, offer BNPL/installment options. These flexible payment options provide users the convenience of paying for the purchases in installments over time. Usually, the customers can choose the payment period and pay the amount in monthly installments with an interest.  

These payment options enable customers to make purchases even when they do not have enough funds to pay the full price of the products upfront. They help customers manage expenses and buy expensive products more easily. 

8. Mobile Payments 

In the mobile payment option, transactions go through mobile apps. During the checkout process, if customers choose the mobile payment option, they will usually get a QR code for the transaction, which they should scan using a mobile payment app from a bank or financial institution. Upon entering a secure passcode, the app will approve the transaction, completing the payment. 

9. Prepaid Cards, Coupon Codes and Gift Vouchers 

The checkout page that allows prepaid cards/coupon codes/gift vouchers has a field to enter a unique code. Entering the code will deduct the value of the coupon/voucher from the total amount. These payment options enable customers to receive gifts and offer a convenient way for customers to purchase online without using traditional credit or debit cards.
