5. What do these common online payment terms mean?

Let’s answer them here:

1. What is an online payment system?

An online payment system is a system that facilitates electronic payment for goods and services.

It involves all processes that enable payment transfers — the payment gateway, payment processor, and merchant account.

2. Why are online payment systems necessary?

Today, purchasing products and services online is more common than ever. In fact, by the year 2040, more than 95% of purchases will be made online.

Online payment services offer a number of benefits to both businesses and consumers, including:

• A streamlined shopping experience
• Keeping payment information secure
• Organizing purchases and transactions
• And much more

Quick and simple shopping experiences are key to creating a positive user experience and boosted sales.

3. How does the online payment process work?

Businesses will follow their online payment system’s instructions for setting up the check out process on their website.

Then, when users make a purchase, they will be asked to enter their card details to pay. Users may also be asked to select the payment method they wish to use, such as PayPal or Google Pay.

If users opt to pay with a payment service such as PayPal or Google Pay, they will be asked to sign into their account if they’re not already. They will then complete their purchase using the service.

If users decide to enter their card details on the website, the company’s online payment service will verify the card details and ensure the customer has enough funds to complete the transaction.

The transaction will then be completed.

4. How do I choose the best online payment system for my business?

When choosing an online payment system for your business, consider the following:

1. Security
2. Cost
3. Integrations
4. Payment methods

Let’s go through each one:

1. Security

Security is one of the most important considerations when choosing an online payment system. Shortlist only PCI-compliant online payment systems.

Make sure these systems also use the latest encryption technologies that protect your customers’ card information from theft.

2. Cost

Most online payment systems have subscription or payment processing fees.

A subscription fee is a monthly or yearly fee that the service charges. Meanwhile, a payment processing fee refers to the charges for every transaction.

Note that some online payment services don’t charge a subscription fee, but they may have higher payment processing charges.

When comparing the fees of different online payment systems, research other possible charges like:

• Setup fees
• Hidden charges
• Refund fees
• International transaction charges

3. Integrations

You must be able to integrate your online payment system into your shopping cart and other apps you use for your business, like accounting software.

Integrations enable you to automate parts of your process, thus saving you time.

4. Payment methods

Find out the payment methods the system supports. It must accept credit card payments and your customers’ other preferred modes of payment like PayPal.

If your customers prefer the pay-by-invoice option, shortlist systems that have this capability.

5. What do these online payment terms mean?

Here are some definition for terms related to online payment systems:

ACH payments

ACH stands for Automated Clearing House. ACH payments refer to electronic credit and debit transfers, allowing customers to make payments from their bank accounts for utilities, mortgage loans, and other types of bills.

Most payment processors offer ACH payment options to their customers, especially for monthly- and subscription-based transactions. Most payment solutions use ACH to send money (minus fees) to their customers.

Merchant account

A merchant account is a bank account that allows a business to receive payments through credit or debit cards. Merchant providers are required to obey regulations established by card associations. Many processors act as both the merchant account and the payment gateway.

Payment gateway

A payment gateway is a service that enables a merchant to process card transactions. It securely passes credit card information between the customer, the merchant, and the payment processor. The payment gateway is the middleman between the merchant and their sponsoring bank.

Payment processor

A payment processor is the company that a merchant uses to handle credit card transactions. Payment processors implement anti-fraud measures to ensure that both the front-facing customer and the merchant are protected.

PCI compliance

PCI compliance is when a merchant or payment gateway sets its payment environment up in a way that meets the Payment Card Industry Data Security Standard (PCI DSS). The PCI DSS standard was created by the PCI Security Standards Council to increase security of cardholder data and to reduce fraud.
