Online payments: Key terms & FAQs

What is a merchant account?

A merchant account typically refers to one of two special types of bank account businesses use to accept payment from their customers, depending on the payment method involved - card payments, or bank debit (AKA ACH debit or Direct Debit).

1) Merchant accounts in card payments

Within the area of card payments, a merchant account allows businesses to receive payments from credit cards and debit cards.

This is only a generalized definition - merchant account is not a universal technical legal term, and despite being used in card networks’ rulebooks (see Visa’s core rules here and Mastercard’s rules here), is also not explicitly defined by them either.

As such, different organizations may interpret the term merchant account differently. This is worth keeping in mind wherever you see the term being used.

With that in mind, the general defining traits of merchant accounts tend to be:

• They are not the same financial product as a regular business bank account

• They cannot be deposited into, or withdrawn from, by the business whose name the account is in

• They accept payments electronically, holding the funds typically for a few days before transferring them to the business’ regular bank account

But why can’t a card payment be made directly into a business’ regular bank account? Why have merchant accounts at all?

By holding the funds for a short period, merchant accounts help reduce fraud. When a transaction is disputed by a customer - known in card payment terms as a chargeback - the funds transferred to the merchant need to be returned. Without merchant accounts, there are two primary fraud risks:

1. The merchant doesn’t want to give the money back - If a merchant hasn’t fully delivered on the promised product or service, their customer deserves the right to a refund. However, once those funds are in the merchant’s hands, the customer has no power to have them returned.

2. The merchant is a fraud - If a merchant is intending to defraud customers by selling a product or service they have no intention of delivering on, once they have the funds in their bank account, they can just pack up and run.

Within the world of card payments, an acquirer is responsible to the card network for the behaviour of its merchants. So in the above two cases, the merchant’s acquirer is bearing the financial risk of the chargeback. With merchant accounts acting as holding accounts for funds, acquirers are able to freeze funds or return them (via the card network) to the customer where necessary, reducing their risk.

Traditionally, the only way for businesses to open a merchant account would be directly via their bank. The barriers to obtaining a merchant account this way were, and largely still are, high. You need to prove you have significant capital, a solid business plan, and a professional online presence. Your bank may require a substantial bond to set one up for you, and the whole process could take several weeks.

Today, a wide variety of payment service providers (PSPs) provide merchant accounts of their own, or have relationships with banks that enable them to help businesses open a merchant account with a bank. The notable advantages for businesses taking this route are:

• It’s cheaper to get started - For newer or smaller businesses who don’t have the capital to secure a merchant account directly from a bank, PSPs can offer a cheaper path.

• Convenience - PSPs often bundle together various payment services a business would require, making using them a quicker and easier path to get started accepting payments.

2) Merchant accounts in bank debit

Like with card payments, merchant account is not a technical legal term within the area of bank debit, and the rules governing each of the different bank debit schemes around the world may not make use of the term at all.

As such, different organizations are likely to use and interpret merchant account differently, and this is worth keeping in mind when you see it being used.

Typical definitions of merchant account include:

• The regular bank account a business holds (Note: This is in direct contrast to how this term is used in card payments, where a merchant account is a distinctly different financial product to a regular bank account)

• A virtual holding account where a bank debit provider (i.e. a PSP which provides bank debit services to businesses) temporarily holds funds from the customer before transferring them to the business’ regular bank account

As a bank debit provider ourselves, we here at GoCardless we use merchant account to mean the latter definition.

But again, why are these kind of merchant accounts required? As part of bank debit payment flows, there can be a period of multiple days between funds being credited to the bank debit provider and notification of payment failure (which would result in that credit needing to be reversed).

Therefore, to accommodate for the possibility of payment failure, bank debit providers need to hold the funds until they are cleared, after which they will transfer them to the merchant’s regular bank account.

What is a payment gateway?

A payment gateway is a software that is involved in processing of payments made by credit card or debit card. As with the term merchant account, payment gateway is not a universal technical legal term, and although you might see it being used by card networks like Visa or Mastercard, is also not explicitly defined by them either. As such, different organizations may interpret the term payment gateway differently. This is worth keeping in mind wherever you see the term being used.

Within the online card payment process, a payment gateway links the merchant’s website (where the customer makes their purchase) to the payment processor / acquirer. When the customer enters their card details into the merchant’s website during checkout, the payment gateway securely transfers them, along with the rest of the information about the transaction, to the payment processor / acquirer.

From there, the transaction information makes its way through the relevant card network to the customer’s issuing bank. The response from the customer’s issuing bank makes its way back via that same path, eventually reaching the payment gateway again, where both the customer and the merchant are informed of whether the transaction is a success or not.

Companies such as Authorize.net and Payment Express provide the services of a payment gateway.

Before applying for a payment gateway, you'll typically need an approved merchant account first. Some providers of payment gateways will help you apply for one.

What is a payment service provider (PSP)?

A payment service provider (PSP) is a company that helps businesses accept payments. Although the term is relevant within the area of card payments (although it is not specific only to card payments), neither Visa or Mastercard explicitly define the term in their rules.

In the context of online payments, PSPs offer businesses various bundled services required to accept payments online - for example, both merchant account and payment gateway facilities. As these facilities can have high barriers to entry for smaller businesses, PSPs - in a broader sense - help reduce the barriers for businesses to accept payments.

Companies such as PayPal and Adyen are PSPs.

Credit and debit card payments aren’t the only payment methods that payment service providers can handle. They often handle a variety of methods, including bank debit and bank transfers, all channelled into the same account for the business. They also tend to offer additional services such as fraud protection.

What is a payment processor?

A payment processor is the facility of an acquirer which transfers transaction details, provided by a merchant through their payment gateway, to the relevant card association (e.g. Visa, Mastercard).

As with the terms merchant account and payment gateway, payment processor is not a universal technical legal term, nor is it explicitly defined by card networks such as Visa and Mastercard. As such, different organizations may use the term payment processor differently, and this is worth keeping in mind wherever you see the term being used.

Commonly, you may see payment processor used interchangeably with acquirer or payment service provider.

How do I set up recurring payments online?

Two popular payment methods to set up recurring payments or subscription payments online are bank debit and credit / debit card.

Similar to how businesses can try setting up their own merchant account and payment gateway, or they can engage the services of a PSP, they can also try accessing bank debit schemes themselves or engage the services of a bank debit provider.

The advantages and disadvantages of bank debit versus credit / debit cards in taking recurring payments online are explored later in this guide.
