By |Published On: August 11th, 2023|

Business-to-business payments play a crucial role in commerce by allowing companies to process payments with each other using specific payment methods and key players to facilitate these transactions. To better understand what and who is involved in these transactions, this article will dive into common business-to-business (B2B) terminology and payment methods.

What are B2B payments?

Unlike business-to-consumer (B2C) payments, where customers pay businesses for goods and services, B2B payments involve one company making payments to another. These payments occur for various reasons, including purchasing raw materials, settling invoices, and procuring services. A reliable B2B payment system plays a pivotal role in the smooth operation of businesses across industries. It’s important to familiarize yourself with some essential terms of the B2B payment landscape to ensure your business can best optimize its payments.

5 B2B payment terms your business should know

Just like learning the basics before tackling a new challenge, knowing these terms will help give you a head start when you explore the details of B2B payments and B2B payment solutions.

Here are some fundamental terms to understand:

  1. Merchant account
  2. Payment gateway
  3. Payment processor
  4. Acquirer
  5. Issuer

Merchant account

A merchant account is a specialized bank account that allows businesses to accept customer payments through credit cards and other electronic payment methods. It acts as an intermediary for transferring funds from the customer’s account to the merchant’s account after a successful transaction.

Merchant accounts are essential for businesses in online commerce or retail environments where card payments are prevalent.

Setting up a merchant account typically involves a partnership between the business, the acquiring bank, and a payment processor. Some merchant accounts may also support additional payment options, such as mobile wallets and digital payment platforms, ensuring a seamless customer payment experience and broadening the business’s reach.

Payment gateway

A payment gateway is a secure online service that enables the authorization and processing of electronic payments for businesses engaged in e-commerce. It acts as an intermediary between customers, merchants, and financial institutions, ensuring that sensitive payment information is transmitted securely and efficiently.

Payment gateways encrypt sensitive payment data, such as credit card details, ensuring secure transmission. The encrypted data is forwarded to the acquiring bank for processing, and upon approval, the payment gateway confirms the transaction to the customer and merchant. Payment gateways are also responsible for facilitating various payment methods, providing transaction reports, and supporting businesses in any online transactions.

Choosing the right payment gateway is essential for ensuring a seamless payment process, customer trust, and success in the digital economy.

Payment processor

What is a Payment processor

A payment processor is a financial institution or service provider responsible for handling the technical aspects of payment transactions. It works with the payment gateway to authorize and settle transactions. It also ensures the secure funds transfer between the customer’s bank and the merchant’s bank account. While the payment gateway focuses on securely transmitting payment data, the payment processor handles the behind-the-scenes operations, including verifying the customer’s payment information, confirming available funds, and coordinating with the acquiring bank to finalize the transaction. Payment processors are essential for businesses to receive timely and accurate payments, as they play a crucial role in streamlining the payment flow and reducing the risk of fraudulent activities. By integrating multiple payment methods and supporting various currencies, payment processors enable merchants to expand their reach and cater to a global customer base. Additionally, payment processors handle issues such as chargebacks and refunds, ensuring a smooth and reliable payment experience for customers and merchants.


Credit card acquirers, also known as payment acquirers, are financial institutions enabling businesses to accept various electronic payments, ensuring seamless transactions for merchants and customers alike.

Acquirers play a vital role by collaborating closely with businesses to establish merchant accounts, which are the foundation for enabling electronic payment acceptance. Acting as intermediaries, they seamlessly process transactions, ensuring the secure transmission of payment data, verifying transaction authenticity, and initiating fund movement. Acquirers are pivotal in acquiring authorization from the customer’s issuing bank, thus greenlighting the transaction. Subsequently, they facilitate the settlement process, overseeing the smooth transfer of funds from the customer’s account into the merchant’s. Acquirers also manage risk by scrutinizing transaction activity to detect fraud or suspicious behavior to safeguard merchants and customers.

Additionally, acquirers facilitate the collection of various fees, encompassing interchange fees dictated by card networks, processing fees, and an array of service charges. These fees cover the essential costs of maintaining a payment processing infrastructure and delivering various necessary services. Recognizing the multifaceted nature of their role, acquirers extend their support beyond the transactional realm, offering dedicated customer assistance. This encompasses addressing inquiries, resolving technical challenges, and ensuring the seamless facilitation of payment processing operations, empowering merchants to focus on their core business objectives.

What is an acquirer in payments?


The issuer refers to the bank or financial institution issuing the customer’s credit card. An issuer plays a crucial role as the entity responsible for granting payment cards and overseeing the financial transactions made using those cards.

Issuers initiate payment card issuance for eligible entities, such as credit and debit cards, and maintain cardholder relationships by managing accounts and providing dedicated customer support. During transaction authorization, issuers evaluate fund availability to ensure seamless payment progression. Their security measures and fraud detection systems actively safeguard cardholder accounts, and they facilitate billing by creating statements while also initiating fund transfers. Moreover, issuers manage credit limits and oversee credit card billing cycles while serving as crucial mediators in dispute resolution. They administer rewards and benefits tied to payment cards, enhancing cardholder experiences.

In essence, issuers play a pivotal role in the B2B payment landscape by issuing cards, ensuring secure transactions, managing financial matters, and delivering essential support services.

Understanding these fundamental terms is just the first step. It’s just as important to be aware of the various popular payment methods that customers or businesses commonly use for their purchases.
