What Is a Third-Party Payment Processor?

Small and medium-sized businesses have two options when it comes to accepting online payments.

They can open a domestic or international merchant account in a bank and handle these transactions independently. It’s the more complicated option due to the stringent regulations and high upfront costs involved.

The other option is to work with a third-party payment processor that help businesses obtain merchant accounts and start processing payments easily. In this case, there are no high upfront costs and fees are based on the volume of transactions.

In this article, we’ll explain what a third-party payment processor is and how merchants can use their services.

Third-party payment processor definition

A third-party payment processor is a financial entity that provides payment processing services to merchants. This payment authority makes it simple for merchants to start accepting payments without the hassle of obtaining their own merchant account with a bank.

A merchant account is a bank account that a business uses to receive electronic payments. Merchants either open their own merchant account or work with a third-party payment processor to start accepting payments through the processor’s merchant account.

Registering a merchant account takes many months and requires obtaining and providing extensive documentation as well as paying costly upfront fees.

Third-party payment processors are practical solutions for all small and medium-sized businesses. They can focus on their core business activities and start processing payments in a matter of days or weeks, not months.

How Do Third-Party Payment Processors Work?

When a merchant works with a third-party payment processor, all payments made to the business are processed through the payment processor’s merchant account. This entity has an agreement with an acquiring bank to process payments for its merchants.

Note: On some occasions, third-party payment processors can open separate bank accounts for merchants to process their payments.

Third-party payment processors are especially valuable for high-risk businesses. Most banks and financial institutions are highly reluctant to process high risk payments due to the delicate nature of the merchant’s business. Third-party payment processors take on the risk and vouch for high-risk merchants.

Any payment processing involves risk of fraud schemes, money laundering, identity theft, and other prohibited transactions. Hence, payment processors screen each new merchant thoroughly and implement security measures, such as 3DS and SCA, and strict policies to protect themselves and their merchants from illicit payments.

Payment processors working with high-risk businesses must track their chargeback ratio carefully. Additionally, they proactively monitor for suspicious activities, especially in card-not-present transactions.
