What Are Online Payment Solutions?

Online payment solutions are the tools and technologies that enable customers to pay for products and services online.

They oversee the entire payment process, from payment method selection to the transfer of funds to the seller’s account.

There are two core aspects of online payment solutions:

• Payment gateways: A virtual point-of-sale that authorizes payments securely.
• Payment processors: A behind-the-scenes communication technology used to transfer funds between the buyer’s and seller’s accounts securely and efficiently.

How Do Online Payment Solutions Work?

Online payment solutions work by automatically checking, facilitating and finalizing payments between a buyer and a seller.

This is done in two broad stages: card authorization and transaction settlement.

• Card authorization: The communication between a customer’s payment method and a payment gateway to enable verification and check available funds.
• Transaction settlement: The communication of transaction approval between a buyer and seller’s accounts, mediated by a payment processor.

Within the wider payment process, there are several steps that every online purchase follows:

• Selection: A customer chooses products or services on an online store.
• Checkout: The customer proceeds to a checkout page to finalize their purchase.
• Payment information: The customer puts their payment details and method of payment into a form.
• Encryption: The payment information is encrypted to ensure its security during transmission.
• Authorization: The payment gateway verifies the customer’s information and authorizes the transaction.
• Processing: The payment processor securely transfers the funds from the customer’s account to the seller’s account.
• Confirmation: The customer receives a confirmation of the successful transaction, finalizing the purchase.

What To Look For When Choosing Online Payment Systems

Choosing the right online payment system for your e-store is a decision that revolves around your target audience.

From managing security concerns to offering the payment methods that your customers use most, your online payment system should build trust and encourage your audience to follow through with their purchases.

Keeping this in mind, here are five core aspects to consider:

1. Security

Your customers’ payment security is the most important factor when selecting your online payment solution.

Did you know that 83% of organizations faced at least one data breach in 2022?

If your customers can’t trust your payment gateways you will lose out on short-term sales and damage your long-term brand loyalty — making security vital for both your customers and your business.

Ensure you understand your online payment solution provider’s security protocols to keep your visitors’ information secure.

For example, some solutions will redirect customers to third-party gateways while others will keep them on-site for payment processing.

If you’re confident in your website’s security strength and want to keep customers on-site for a smooth checkout process, choose the latter. Meanwhile, the former is a better option for smaller online stores whose security capacity is weaker than specialist providers.

2. Usability

The usability of your checkout and online payment process is a key driver in completing sales.

In fact, according to Baymard Institute, 18% of cart abandonments are a direct result of a complicated or longwinded payment process.

By choosing a user-centric online payment solution with a user-friendly interface, multiple payment options and a painless payment process, you can reduce checkout frictions and drive completed conversions.

3. Costs

Online payment solutions have varying fees, such as transaction or membership costs, which can be internalized or passed onto the consumer.

While passing the fee onto the consumer may be tempting, Baymard Institute’s research also found that 47% of cart abandonments are attributed to extra costs.

In turn, consider the transaction and payment gateway subscription fees before signing up for a tool that eats away at your profit margins or total sales.

4. Localization

Whether geo-targeting a specific location or enabling international sales, your online store can target growth through localization.

In fact, the value of cross-border eCommerce is set to exceed $3.4 trillion by 2028, up from $1.6 trillion in 2023.

Adding multiple currencies to your online payment solution can help your business tap into this opportunity of global eCommerce.

5. Compatibility

For an online payment solution to fit your eCommerce business, it must integrate with both your online platform and your customers’ preferred payment methods.

69% of online payments are made via wallets in Asia-Pacific compared to just 32% in the United States, highlighting just one of the differences in consumer preferences based on location.

By addressing these differences, you can choose an online payment solutions provider that integrates with the gateways your consumers prefer — boosting sales and limiting cart abandonments.
