Online Payment Failure: Why it Happens and How to Avoid it  (2024)

None of us like to see an online payment failure message after we’ve spent time entering all our payment details at checkout. Going through the payment flow again doesn’t take long, but a failed transaction can also make you question how trustworthy the e-commerce store is. This ultimately leads to lost sales for merchants.

In fact, online merchants lose 62% of customers who experience a failed transaction.

Digital payments continue to be the most common way to make and receive payments. As an e-commerce business owner, online payment failures are an issue that shouldn’t be neglected. Doing so can result in a poor customer experience, more abandoned cards, and lost sales revenue.

Why do online payments fail?

The easiest way to understand why online payments fail is to first take a look at the online payment process.

When the consumer starts an online transaction, the payment gateway facilitates the route to and from the payment processor. After running fraud checks, and 3D Secure confirmation, the card data gets sent to the acquiring bank (also known as the merchant acquirer). Then the acquiring bank securely sends the payment information to the card schemes. Also known as card networks (i.e. Visa, Mastercard UnionPay, JCB, and American Express). After another round of security checks, the payment is sent to the issuing bank where it is then either approved or declined. Then a message is sent back to the acquirer and finally the approved or declined payment message is sent to the merchant. All these steps happen in a matter of milliseconds.

What are the different types of payment failures?

Payment failures can be categorized into different types depending on the situation.

Here are a few types of online payment failures:

1. Online payment failure from the consumer’s side. These types of errors can happen when a customer provides incorrect card details, the wrong one-time password (OTP), or they have insufficient funds in their account. It’s also referred to as an incomplete payment.
2. Online payment failure from the merchant’s side. These types of failures can happen when there is a technology or security error that the seller is responsible for.
3. Online payment failure when there is a data transfer error. This happens when the customer receives a payment failure message, but the payment eventually goes through so the cardholder’s account gets debited.
4. Online payment failure when the amount is not charged. This means the payment failed and the customer’s account was not debited.

What causes online payment failure?

There are various factors that can contribute to online payment failure. As we already mentioned, failed payments from the customer's side are sometimes caused by providing incorrect details or happen due to a lack of funds.

From the merchant’s side, the reasons for online payment failure are more complex, making it important to understand the causes in more detail.

Here are the main reasons for online payment failure from the merchant’s side:

System downtime

The players involved in online payment processing include the payment gateway, payment processor, acquiring bank, and issuing bank. These parties experience their own downtime, whether it’s planned for or not.

If any of the key players in the online payment process experience downtime during a transaction, the server can’t get approval for it. When this happens, the transaction can’t be completed and it results in an online payment failure.

Payment technology fails

Let's take another look at the online payment flow infographic above. Payment processing involves a considerable amount of steps to debit the payment from the customer’s account and credit it into the merchant’s account.

When your customer starts the payment process, they need to select a payment method (credit card, Apple Pay, Google Pay, Bizum, installment payments, etc.), and after choosing the payment option they need to input payment details. For example, their name, credit card number, and CVV (i.e. credit card security code).

Then the payment data is sent to the payment gateway, so it can transfer it to the card network. After the details are verified and the transaction is authorized, the amount is sent to the acquirer, and then transferred to the merchant’s account.

Online payment failure can happen if a small failure happens during any one of these steps in the payment process.

Security is compromised

Virtually every player involved in online payment processing is required to uphold security requirements to detect and avoid online payment fraud.

Banks, including issuers, are armed with advanced technology that detects and analyzes fraud.

These fraud tools verify and analyze if the online transitions are authenticated based on previous spending patterns. If something seems out of place, the transaction is blocked and declined.

There are a few common red flags that cause transactions to be blocked or declined:

• Bank Identification Number (BIN) is blacklisted. A transaction can get denied if the BIN on the card is blacklisted. Blacklisting tracks and records cardholders who show inconsistent activity. Then the system uses filters to identify customers who aren’t trustworthy. If there are any red flags, the authenticity of the shopper’s transaction is checked.
• The maximum transaction limit is surpassed. Some merchants set a maximum transaction amount and if the limit is exceeded the transaction may be declined by the payment gateway.
• There is a security threat. Suspicious activity from the issuing bank’s side that threatens security can result in a blocked or declined transaction.

Additional reasons for online payment failure

The reasons we’ve listed above are the most common causes for online payment failure, but there are a few more to be aware of. Let’s take a look at them here:

• Merchant account blocks the transaction
• Credit or debit card is expired or canceled
• The billing address is invalid
• The bank flagged the cardholder’s account
• The customer’s credit card is maxed out
• The payment gateway is not configured properly
• The consumer’s account is suspended or closed
• The payment gateway does not support the online payment method chosen by the consumer

Common online payment failure error messages

Understanding online payment failure messages and when they occur can help you manage customer complaints and pinpoint recurring issues.

Here are the most common online payment failure messages to be aware of:

• The transaction cannot be authorized. This error message usually occurs when the password or OTP is wrong.
• Signature validation failed. This error message appears when the 3D signature is wrong. A 3D signature is required from the cardholder to validate the transaction.
• Payment not captured. This error message happens when the customer has insufficient funds in their account or if they input the wrong credit card security code (CVV).

4 tips to help reduce online payment failure

Online payment failures are inevitable in e-commerce. But using a payment service provider (PSP) that's secure, has advanced functions, and allows you to accept many types of payment methods can help you reduce failed online payments.

1. Use a payment gateway that routes transactions to multiple payment processors

During the online payment process, transactions get sent to various parties including the payment processor. If your payment gateway only allows you to route payments to one processor, the chances of experiencing system downtimes and failed payments are higher.

Use payments orchestration to send transactions to multiple payment processors. This way, if one is down, your customers won’t immediately receive a payment failure message. Instead, you can set up routing rules to send the payment to another processor. You’ll approve more payments, improve the customer experience, and increase your conversion rate.

2. Find an e-commerce payment platform with advanced functionalities

Payment processing may happen in a matter of seconds, but the work happening behind the scenes is complex. Opting for basic digital payment features may not be sustainable as your business grows.

Our payment technology goes beyond helping you accept online orders. Its serverless architecture allows you to scale and process a high volume of transactions without system crashes or technology failures.

3. Prioritize online payment security

Following online payment security regulations doesn’t only protect your customers, it also protects your business from fraudsters and other security risks.

But figuring out what steps to take to become compliant can be overwhelming when you’re building a brand.

We’ve already taken the necessary steps to follow payment security regulations. So, you can leave your payment security up to us — we are PCI DSS Level 1 compliant.
