When can we say a payment is truly finished? Is it when the Payer’s money leaves their account, or only when the Merchant actually receives it?
The payment process involves several steps that take place behind the scenes. Once a transaction is made, it can take up to a few days before the funds appear in the Merchant’s account. During that time, the transaction might be shown as pending, processing or in another non-final status. At the end of the payment process, it can be in a successful final status, or it can even be declined or reversed.
So, what exactly happens during the payment process?
The payment process is the process of transaction initiation with the goal of transferring money from the Payer's account to the business receiving the funds.
In the UK, this process is supported by strong Payment Systems. The Faster Payments Service sends money between banks almost instantly, and Bacs handles millions of salary payments and direct debits every day. Card payments run through networks (such as Visa and Mastercard), and these have built-in fraud checks.
Open Banking rules require banks to use strong customer authentication and allow approved third parties to make payments or access account information. This has made it possible to offer budgeting apps and faster payments to businesses and still keep payments secure.
The payment process in banking involves several key players:
Orchestration, the behind-the-scenes coordination of all the systems and steps involved in processing a transaction, manages how the parts work together.
As we’ve mentioned, payments go through a few important steps before they’re complete:
A transaction starts when a customer chooses a payment method and provides their payment details. It can be done online through a website or app, in-store via a card terminal, or on a mobile device using wallets like Apple Pay, Google Pay or other APM..
In the UK, most people tend to pay for things with a debit or credit card or just tap their card or phone for a contactless payment.
Once initiated, the payment must be confirmed as legitimate and approved for processing. Authentication methods include PIN entry, 3-D Secure, PSD2 Strong Customer Authentication, and biometric checks like fingerprint and facial recognition.
After preauthorisation, funds are placed on hold in the customer’s account.
Capture is the step in which the merchant requests the previously authorised funds to be charged to the customer’s card and moved toward settlement. Some merchants capture immediately, while others wait until goods are shipped or services are provided.
Once capture is successfully processed, the previously authorised amount is charged to the customer’s card and moves toward clearing and settlement. Capture therefore marks the transition from funds being temporarily held after preauthorisation to the merchant requesting those funds for the completed transaction.
If the merchant does not proceed with capture, a Cancel operation can release the amount held by the preauthorisation, making those funds available to the customer again.
Clearing is the process of sharing transaction details between the Merchant’s bank (acquirer) and the Customer’s bank (issuer) through payment networks. Settlement refers to the stage where the funds are transferred into the Merchant’s account. In the UK, this process typically takes one to three working days.
Merchants compare payment records with internal sales, accounting and settlement data to confirm that transactions have been recorded and settled correctly. Accurate payment reconciliation helps identify discrepancies such as missing or duplicate transactions, incorrect amounts and differences between payment and settlement records.
Payment reversals happen when money that was already authorised or transferred is sent back to the Customer. They can occur for a variety of reasons, from a customer changing their mind to a disputed transaction or a technical issue during payment processing.
When you make a payment, it may show different statuses as it moves through the processing steps:
The payment has been approved by the Customer’s bank or card issuer, but the money has not yet moved. The bank confirms there are enough funds or credit and temporarily reserves the amount.
The payment is in progress but not yet finalised. This can occur due to bank processing delays, fraud checks, unusual transaction reviews, or the time between preauthorisation and capture. Pending doesn’t always indicate a problem.
At this stage, the merchant finalises the payment and requests the funds. The reserved amount from the preauthorisation is taken from the Customer’s account. In many businesses, capture happens right after preauthorisation, but some delay it until goods are shipped or services are provided.
A transaction marked as processed has been successfully handled by the payment system, but this does not necessarily mean that funds have already reached the merchant’s bank account. The exact meaning of a processed status depends on the payment flow and provider, while settlement refers to the stage when funds are transferred according to the merchant’s settlement arrangement.
This is the transfer of funds from the customer’s bank to the merchant’s account. Depending on the payment method and agreements between banks, this process takes anything from a few hours to several working days.
A payment has been refused by the acquirer or card issuer. Common reasons are insufficient funds, entering the wrong details, using an expired card, a suspected fraud alert, or hitting the credit limit. Let customers know why it happened and offer another attempt to avoid frustration.
A refund returns money to the customer, either partially or in full, due to returned goods, order cancellations, or service issues. Depending on the payment method, the refund may take a few days to show in the customer’s account.
A chargeback happens when a customer disputes a payment with their bank, and the bank sends the money back. This happens because of fraud, missing deliveries, or goods that aren’t as described. Merchants must provide proof to challenge unfair chargebacks and avoid losing money or paying extra fees.
Businesses face various challenges and risks that impact the speed and success of transactions:
Payment fraud can take many forms, such as stolen card details, identity theft, phishing scams, or account takeovers. Security gaps, such as weak authentication, outdated software, or poor encryption, give criminals an opening. As a result, fraud can erode trust and cause serious financial losses for both merchants and customers. A solid fraud prevention strategy combines transaction monitoring, authentication and risk controls to identify suspicious activity throughout the payment process.
Every failed or declined payment risks losing a sale and leaving a customer annoyed. If it happens too often, it can hurt the business’s reputation and make customers think twice about coming back.
Disputes take time to resolve and often involve providing evidence to the bank. Even if the Merchant wins, chargebacks can mean extra costs, lost time, and higher risk ratings with payment providers. Understanding common chargeback causes, as outlined in the chargebacks 101 guide, can help merchants identify preventable disputes and improve their chargeback prevention processes.
Payment businesses in the UK and EU operate under separate but related regulatory frameworks. In the EU, PSD2 introduced Strong Customer Authentication (SCA) requirements for many electronic payments, subject to exemptions. In the UK, SCA requirements are implemented through the Payment Services Regulations 2017 and related FCA technical standards.
Data protection rules, including the GDPR in the EU and UK GDPR in the UK, apply when businesses process personal data in connection with payments. In the UK, the FCA authorises or registers relevant payment service providers and supervises compliance with applicable payment-services requirements.
Businesses that store, process or transmit cardholder data must also determine the PCI DSS requirements that apply to their environment and use the appropriate validation documentation where required.
Failure to meet applicable regulatory or industry requirements can result in regulatory action, financial penalties, operational restrictions or consequences under agreements with payment providers.
Here, we’ll share practical tips for managing the full payment process effectively and improving overall payment performance:
The foundation of a strong payment process is the provider you choose.
Fraud prevention protects your revenue and your reputation. Use tools like 3-D Secure authentication, AVS (Address Verification Service), and real-time fraud scoring to spot suspicious activity before it becomes a problem. Multi-factor authentication and tokenisation make payments more secure, too.
Training staff to recognise signs of fraud, such as unusual order patterns or mismatched delivery addresses, also helps keep threats in check.
Constant visibility into payment activity allows businesses to detect issues early on. Real-time dashboards and alerts can flag failed transactions, unusual traffic spikes, or patterns that suggest fraud.
Beyond spotting problems, consider using analytics to identify trends. For example, you might notice that certain payment methods work better than others, or that declines happen more often at specific times of day. Then, it’ll be easier to adjust processes.
Complying with payment regulations protects your business and keeps you on the right side of the law. Following PSD2 and GDPR standards helps avoid penalties and reassures customers that their payments are secure.
Clear information about terms, fees, and refund timelines further strengthens trust and sets the right expectations.
The way payments are approved and processed is set to change dramatically in the coming years. Data-driven technologies are leading the charge:
Alongside these innovations, new powers for UK banks to hold suspicious payments, tighter rules to safeguard customer funds from 2026, and enhanced data sharing will boost overall payment security.
Anyway, forecasts help, but the payment landscape shifts in unexpected ways. Keep an eye on industry news and payment trends to spot changes early and respond in time.
The payment process is the process of transaction initiation with the goal of transferring money from one instance to another. It includes steps like checking if you have enough money and moving funds between banks.
The main parties involved are the payer, the connecting party, and their banks. There are also companies handling the payment behind the scenes, like card networks and providers.
Transactions move through a few key steps: starting the payment, getting approval, transferring money between banks, and finally settling the amount. Each step helps make sure the payment is secure and valid.
Preauthorisation happens as the bank checks if you have enough money and approves the payment. It places a quick hold on your funds before the payment goes through. If the bank denies it, the payment won’t happen.
Merchants can avoid declines by making sure payment information is entered correctly and using tools to spot fraud. Offering different payment options helps, too. Keeping systems up to date also lowers the chance of problems.
A chargeback happens when a customer asks their bank to reverse a payment because they’re unhappy or suspect a problem. This can cost the business money and lead to extra fees.
Payment data is kept safe using encryption, which scrambles the information so others cannot read it. Businesses also use other strong security steps, including monitoring suspicious activity, protecting servers, and updating safety measures.
In the future, data-led innovations in biometrics, cloud computing, artificial intelligence, and tokenisation will change how payments are approved and processed. New rules and better fraud protection will also improve payment security.
