Top 7 Online Payment Services & Systems in 2024

What is an online payment service?

An online payment service is a piece of digital software that makes the transaction of funds across the internet possible.

If you’re a business owner, this technology helps you accept electronic payments by acting as a bridge between customers buying your product or service and the funds being safely transferred to your bank.

Online payment solutions are a huge part of the digital economy – a whopping two thirds of adults worldwide use digital payments to send and receive money¹.

It doesn’t matter if you’re selling software on a website or eco-friendly houseware in store, it’s important you have a strong online payment system on your side. This software not only makes sure you get paid, but it can also enhance customers’ experience, help you move into new regions and streamline your end-to-end financial operations.

Online payment systems typically include the following features:

• Secure payments

• Fraud prevention

• PCI compliance

• Business accounts

• Automated payment workflows

• Reporting and analytics

Top features to look for in an online payment solution

Choosing the right online payment solution can be a business critical decision. The best providers are secure, quick and help you grow. Here’s a what to look out for:

• Type of solution: find out if your provider is a payment facilitator, Independent Sales Organisation (ISO) or merchant acquirer – each plays a different role in the payment ecosystem and the level of support between them can vary.

• Security: look for software that protects your customers’ funds and data by using advanced encryption, fraud prevention systems and being PCI DSS compliant.

• Integration capabilities: your online payment software should integrate easily (no code required) with other business systems like your accounting software, CRM and eCommerce platform.

• Payment methods: offering your customers a variety of payment methods can help boost your market share, especially if you’re operating internationally.

• Scalability: look for a solution that can grow with you. It should be able to handle increased transaction volumes and multiple overseas markets without significant disruptions. 

How does an online payment service work?

Online payment service providers work by securely processing electronic payment transactions between buyers and sellers over the internet. This software makes sure your customers’ money moves safely from their credit card or digital wallet to your bank.

How? By encrypting your customers’ financial data and sending it to the relevant payment processor to be authenticated and approved. If successful, the customer’s funds will then be transferred to your business account.

But many online payment services are more than a mere transactional tool. 

Platforms like Airwallex offer several additional functionalities that help you manage your funds better, reduce finance team admin hours and save on transaction and currency fees.

Online payment services typically work by:

• Processing transactions securely: when your customer makes a purchase, their payment information is encrypted and sent to your bank (acquiring bank), and in turn the issuing bank, for verification. After successful authorisation, the online payment system communicates confirmation to both you and your customer.

• Safeguarding businesses and customers: good online payment providers have stringent security protocols. They protect sensitive customer information via end-to-end encryption, fraud protection measures and complying with global standards like PCI DSS.

• Automating supplier payments: some solutions help ensure timely supplier payments and save finance team admin hours by setting up scheduled payments for recurring expenses and executing cross-border transactions with ease.

• Integrating with existing business tools: minimise manual administration and the potential for errors by integrating your online payments platform with accounting software like QuickBooks or Xero, and eCommerce platforms like WooCommerce.

• Streamlining funds management: providers can help you manage your money and streamline your operations by offering real-time visibility over cash flow, expense management and the ability to hold multiple currencies in one account.

• Supporting international payments: global online payment providers help businesses grow across borders by supporting multi-currency transactions, slashing hidden foreign transaction fees and offering market-leading FX rates.

• Offering dispute resolution services: good customer support is vital when managing financial transactions. Refund requests and chargebacks are typically supported by investigation and meditation processes.

In summary, an online payment service streamlines and secures the complex process of online transactions, making digital payments possible and helping businesses unlock new opportunities.

How providers are consolidating different roles within online payments

How to reduce online payment processing fees?

Fees for online payment processing can stack up quickly if you’re not careful. Between transaction fees, foreign transaction fees, chargebacks and monthly subscriptions, there are a lot of costs to consider when choosing a new provider.

Thankfully, you can make smart choices to keep within your operating budget. For enterprises with a high volume of transactions every month, choosing a supplier

with a subscription model may suit. If you’re operating across multiple regions, finding an online payments solution with no foreign transaction fees and low FX rates would likely be a priority.

Here are 7 ways you can keep costs down: 

• Get clear on what you need (and what you don’t): assess the volume and type of transactions your business predominately processes. Providers offer several pricing models, including fixed rate and subscription-based models. For fewer transactions, a fixed rate provider might be more cost-effective, while for larger international volumes, a provider with interchange-plus pricing could offer savings.

• Find a low-cost payment gateway: if you aren’t ready to use an end-to-end online payments solution, try integrating your payment processing with gateways that offer lower fees for certain types of transactions. Some gateways have special arrangements or lower fees for transactions processed through specific channels.

• Use ACH/SEPA/BACS direct debit where possible: for recurring payments, consider using ACH, SEPA or BACS direct debit options. These typically incur lower fees than credit card transactions and are ideal for subscription-based models or businesses with recurring billings.

• Find a global solution: if you have customers around the world, you can reduce hidden and unnecessarily high costs by choosing a provider that offers low or no foreign transaction fees and market-leading currency conversion rates.

• Be wary of chargebacks: customers can often initiate chargebacks when they feel they are entitled to a refund. This can be subjective and result in lost revenue as well as additional fees. By having clear customer communication with customers, transparent refund policies and robust fraud detection measures you can minimise sneaky charges.

• Avoid long-term contracts: opting for a flexible online payments supplier means you’ll be able to adapt your payment processing solutions as your needs change and you’ll only pay for the transactions you process.

• Review your payment provider: pricing can change with the economic environment and new suppliers come into the market every year. Make sure you review your options regularly to ensure you’re getting the best deal.

What questions to ask when onboarding an online provider?

 There are lots of online payments providers to choose from, so it’s important you ask the right questions to find a partner that suits your business needs. Ending up in a lengthy contract with a solution that isn’t right can be costly, frustrating and could damage your customer relationships.

Here’s a list of questions to ask your online payments company when you’re in the onboarding phase:

• What are your security protocols? Safe and secure payments are the core function of an online payments solution. Find out how the provider conducts KYC/AML checks, how advanced their encryption process is and what their fraud detection capabilities are. At minimum they should comply with industry standards PCI DSS.

• What payment methods are available? Offering your customers local payment methods is important and can boost your market share. Ask what payment methods they support – just well-known credit and debit cards or local options like iDEAL and alternatives such as Buy Now, Pay Later and cryptocurrency?

• What are the costs involved? Hidden fees can quickly add up, especially if you’re moving money across borders. Ask about all the potential costs associated with the service, including transaction fees, monthly fees, setup costs and conversion fees.

• Do you support global payments? Beyond understanding the cost of accepting international payments, it’s also important to understand if your provider allows you to collect and hold multiple currencies, or if you’ll be forced to convert all payments.

• What integrations do you offer? Most popular online payments suppliers offer integrations with major accounting, CRM and eCommerce platforms to help streamline your operations. Pick a provider that seamlessly fits with your existing software.

• When is customer support available? It’s important you feel supported if there is an issue. Ask about response times and what kind of customer service is available when, from emails to phone lines and chatbots.  

• How do you support businesses that scale quickly? It costs time and money to switch services every couple of years. Check your new provider can help you as you scale with increased transaction volumes and the ability to operate in multiple overseas markets without significant disruptions.

• What is your policy for refunds and chargebacks? While you may not think customers will want regular refunds, your supplier could protect your funds in the future with a robust chargeback policy.

• Do you offer reporting tools? Find out what kind of analytics are available with your platform and how detailed they are. These can help streamline reconciliation and accounting processes and give you valuable insights into your financial performance.
