Every time a customer taps, inserts, swipes, or enters their credit card, an incredible amount of technology works behind the scenes in just a few seconds.

Most business owners know they need to accept credit cards, but very few understand what actually happens after a customer pays. That lack of understanding often leads to confusion about merchant statements, processing fees, and choosing the right payment provider.

At JadaPay, we believe business owners should understand exactly how they get paid. Once you understand the process, you’ll be in a much better position to reduce fees, improve cash flow, and choose the right payment solution for your business.

Let’s break it down step by step.


The Five Steps of Payment Processing

Although the process happens in only a few seconds, there are several organizations involved in every card transaction.

Step 1: The Customer Pays

Everything begins when a customer chooses to pay using a credit card, debit card, mobile wallet, or contactless payment.

The payment may be accepted by:

  • Credit card terminal
  • Point-of-sale (POS) system
  • Mobile card reader
  • Virtual terminal
  • Online checkout
  • Mobile app
  • Invoice payment link

Regardless of how the payment is made, the process is very similar.


Step 2: The Payment Information Is Encrypted

Before any information leaves your business, it is encrypted to help protect sensitive cardholder data.

Modern payment terminals use technologies such as:

  • EMV chip security
  • End-to-end encryption
  • Tokenization
  • PCI DSS security standards

These security measures help reduce fraud and protect both your business and your customers.


Step 3: Authorization

Your payment processor sends the transaction through the appropriate card network.

For example:

Customer Card

Visa

Customer’s Bank

The issuing bank checks several things:

  • Is the card active?
  • Is there enough available credit or funds?
  • Has the card been reported stolen?
  • Does the transaction appear legitimate?

Within just a few seconds, the bank sends one of two responses:

✅ Approved

or

❌ Declined


Step 4: The Transaction Is Approved

Once approved, your customer receives a receipt, and your POS system records the sale.

However…

At this point, you haven’t actually received the money yet.

The transaction has only been authorized.

The funds still need to be settled.


Step 5: Settlement

At the end of the business day (or multiple times throughout the day, depending on your setup), your payment terminal sends all approved transactions in a batch.

The processor then begins transferring the funds through the banking system.

Most businesses receive deposits within:

  • Same day (where available)
  • Next business day
  • Two business days

Deposit timing depends on your processor, bank, transaction types, and funding schedule.


Who Is Involved in Every Transaction?

Many business owners think there are only two parties involved:

  • The customer
  • Their business

In reality, several organizations work together to complete a payment.

The Customer

The person making the purchase.


Your Business

The merchant accepting payment.


Payment Processor

The payment processor securely routes transaction information between all parties involved and helps facilitate authorization and settlement.

Processors also provide services such as:

  • Fraud tools
  • Reporting
  • Customer support
  • Payment hardware
  • Software integrations

Card Network

Examples include:

  • Visa
  • Mastercard
  • Discover
  • American Express

The card network provides the infrastructure that connects banks and processors.


Issuing Bank

This is the bank that issued the customer’s card.

Examples include:

  • Chase
  • Bank of America
  • Wells Fargo
  • Capital One
  • Credit unions

The issuing bank decides whether to approve or decline the transaction.


Acquiring Bank

The acquiring bank (sometimes called the merchant bank) works with your payment processor to help move funds into your business account.


Why Do Businesses Pay Processing Fees?

One of the biggest misconceptions is that payment processors keep all of the fees.

They don’t.

Processing costs are generally divided into three categories.

Interchange Fees

These are paid to the bank that issued the customer’s card.

Interchange rates are established by the card networks and vary based on factors such as:

  • Card type
  • Industry
  • Transaction method
  • Rewards program
  • Business category

Card Brand Assessments

These are fees charged by the card networks for using their payment systems.


Processor Fees

Your payment processor charges for providing services such as:

  • Customer support
  • Equipment
  • Reporting
  • Security
  • Payment gateway
  • Software
  • Account management

Different processors use different pricing models, which is why businesses with similar sales volumes can end up paying very different amounts.


What Can Increase Your Processing Costs?

Several factors can affect what your business pays.

These include:

  • Keyed-in transactions
  • Rewards credit cards
  • Business credit cards
  • Corporate purchasing cards
  • Online transactions
  • High-risk industries
  • Chargebacks
  • Fraud
  • Older equipment
  • Inefficient pricing models

Understanding these factors can help you identify opportunities to lower costs.


Common Types of Payment Processing

Today’s businesses often accept payments in more than one way.

In-Store Payments

Chip, tap, and swipe transactions using a payment terminal or POS system.


Online Payments

Customers complete purchases through your website or eCommerce platform.


Mobile Payments

Businesses accept payments using smartphones or mobile card readers.


Virtual Terminal

Ideal for businesses that accept payments over the phone or by invoice.


Recurring Billing

Perfect for:

  • Memberships
  • Subscriptions
  • Service contracts
  • Monthly retainers

Choosing the Right Payment Processor

When evaluating payment providers, don’t focus only on the advertised rate.

Look for a provider that offers:

  • Transparent pricing
  • Responsive customer support
  • Modern payment technology
  • Fast funding
  • Secure processing
  • Software integrations
  • Industry expertise
  • Scalable solutions

The right payment partner should help your business grow—not just process transactions.
