How do merchant services work?

Merchant services are the backbone of modern commerce, enabling businesses to accept electronic payments from customers. Understanding how this service works is benefits all parties involved, especially businesses that need to use them, so let’s demystify the process and explore the key components that make merchant services tick.

Merchant services encompass the infrastructure, technology, and support required to facilitate electronic payments. This includes the ability to accept credit and debit cards, process online payments, and handle point-of-sale (POS) transactions. The main components of merchant services include:

  1. Merchant Account: This specialized bank account allows businesses to accept credit and debit card payments. It acts as a holding account for funds before they're transferred to the business's main bank account.

  2. Payment Gateway: This software encrypts and securely transmits transaction data between the merchant and the payment processor.

  3. Payment Processor: This company handles the communication between the merchant, issuing bank, and acquiring bank to authorize and settle transactions.

  4.  Point of Sale (POS) System: This hardware and software combination allows businesses to process in-person transactions.

This is a step-by-step breakdown of how merchant services operate during a typical transaction:

  1. Customer Initiates Payment: A customer decides to purchase a product or service using a credit/debit card, either online or at a physical location.

  2. Authorization Request: The merchant’s POS system or payment gateway captures the transaction details, encrypts them, and sends a transaction authorization request to the payment processor.

  3. Transaction Routing: The payment processor forwards this request to the card network (e.g., Visa, MasterCard) which then contacts the customer’s issuing bank to verify the transaction details. For clarity, the issuing bank “issued” the cards that were used in the transaction.

  4. Approval or Decline: The issuing bank checks the customer’s account for sufficient funds or credit limit and sends an approval or decline message back through the card network to the payment processor.

  5. Authorization Response: The payment processor relays the authorization response to the merchant’s POS system or payment gateway, usually within seconds. If approved, the sale is completed, and a receipt is generated.

  6. Clearing and Settlement: Approved transactions are grouped and sent in batches at the end of the business day to the acquiring bank. The acquiring bank, through the payment processor, requests the funds from the issuing banks and deposits them into the merchant account after deducting any fees.

Using merchant services involves various fees, which can vary based on the provider and the business's size and type.

  • Transaction Fees: A percentage of each transaction and a cents per transaction, although it’s sometimes is billed as a single (percentage) flat rate.

  • Monthly Fees: Regular fees for maintaining the merchant account and payment gateway, and sometimes equipment cost are charged. 

·         Incidental Fees: Charges for things like chargebacks, PCI compliance, or additional services.

Merchant services are crucial for businesses of all sizes for several reasons:

  1. Enhanced Customer Experience: Accepting multiple forms of payment, including credit cards, debit cards, and digital wallets, meets customer expectations and can lead to increased sales.

  2. Security: Merchant service providers offer security features that help protect businesses from fraud detection and data breaches, ensuring customer trust.

  3. Efficiency: Automated payment processing reduces manual errors and speeds up transaction times, enhancing operational efficiency.  Reporting tools often yield actionable data.

  4. Scalability: As businesses grow, merchant services can scale with them, providing more advanced features and support for higher transaction volumes.

As technology evolves, so do merchant services. The rise of mobile payments, contactless transactions, and alternative payment methods like digital wallets are continuously shaping the landscape of electronic payments.  By leveraging merchant services, businesses can streamline operations, enhance customer experience, and ultimately drive growth in today's digital economy.
