Online credit card processing allows businesses to accept credit and debit card payments through websites, secure checkout pages, electronic invoices, and other internet-connected payment tools. To accept online payments, a business generally needs a compatible payment solution that can securely collect payment information, request authorization, and coordinate transaction processing.
That sounds straightforward, but choosing the right setup involves more than adding a payment button to a website.
Business owners need to understand how payment gateways work, what processing fees actually include, how online transactions are protected, and when money from completed sales becomes available in their bank accounts.
I’ve worked with small business owners in the merchant services industry since we founded Valued Merchant Services in 2006. One lesson that continues to matter is that the most useful payment system isn’t necessarily the one with the most features or the lowest advertised rate. It’s the one that fits how the business sells, bills customers, manages cash flow, and handles problems when they occur.
A retailer shipping products nationwide has different payment needs from a contractor collecting deposits, an accounting firm sending invoices, or a membership business collecting recurring payments.
In this guide, I’ll explain how online credit card processing works, the different ways to accept payments, the costs and security requirements to understand, and how to choose a solution that makes sense for your business.
Online Credit Card Processing at a Glance
- What it does: Lets businesses accept card payments when the customer and card are not physically present at a payment terminal.
- What you may need: A payment gateway or payment platform, a compatible processing arrangement, and an approved way to collect payment information.
- Ways to accept payments: Ecommerce checkout, hosted payment pages, payment links, virtual terminals, and recurring billing.
- Typical costs: Processing fees plus any applicable gateway, software, monthly, or other transaction charges.
- Security: PCI DSS obligations still apply. Secure payment components, appropriate tokenization, and fraud controls can help reduce risk.
- Funding: An approved online payment is not the same as money being deposited into your bank account.
- Best approach: Compare total cost, compatibility, customer experience, support, security, and settlement terms before choosing a provider.
How Does Online Credit Card Processing Work?
When someone pays for a product or service online, several systems typically work together to authorize and process the transaction.
The customer may see only a checkout page and confirmation message, but the underlying process involves payment technology, financial institutions, and card networks.
The Payment Gateway
A payment gateway provides technology that securely transmits payment information or payment tokens between the checkout environment and the appropriate processing systems.
Depending on the integration, the gateway may also provide features such as transaction reporting, customer payment storage through tokens, fraud screening, recurring billing, and virtual terminal access.
The gateway is important, but it is not necessarily the company that provides the merchant’s acquiring relationship or deposits settlement proceeds.
The Payment Processor
The payment processor helps route transaction information through the relevant card-payment infrastructure.
It coordinates with acquiring services and card networks so the issuer can evaluate the authorization request.
Some providers package gateway and processing services together. Others use separate companies or technology platforms.
The Merchant Account or Payment Acceptance Arrangement
A merchant account or an appropriate payment acceptance arrangement allows a business to process card payments under the applicable provider terms.
Depending on the provider’s business model, a merchant may have a dedicated merchant account or receive payment services through a payment facilitator arrangement.
Either way, the business should understand who provides the processing service, which agreement applies, how funds are handled, and whom to contact for support.
What Happens When a Customer Clicks Pay?
Consider a customer purchasing a $125 item from an online retail store.
- The customer submits payment. The customer enters card details into an approved checkout or uses another supported method, such as an eligible digital wallet.
- The payment information is securely handled. The gateway or payment platform captures or tokenizes the relevant details according to the integration.
- Authorization is requested. The transaction is routed through the processing and card-network systems to the card issuer.
- The issuer responds. The transaction may be approved or declined based on account status, available credit or funds, fraud checks, and other conditions.
- The transaction is captured. Depending on the configuration, capture may occur immediately or after the merchant takes another action.
- Clearing and settlement follow. The relevant parties complete the financial processing, and the merchant receives proceeds according to its funding arrangements.
Important distinction: Authorization, capture, settlement, and merchant funding are separate stages. An approved transaction does not mean the money has already reached the merchant’s bank account, and authorization alone does not guarantee protection against a later dispute.
For a broader explanation of account approval, equipment, and setup, see our guide to accepting credit card payments.
Five Ways Small Businesses Can Accept Credit Card Payments Online
Not every business needs a full ecommerce shopping cart.
The best payment method depends on whether customers are shopping independently, paying invoices, purchasing services, or making recurring payments.
1. Ecommerce Website Checkout
An online store typically uses a shopping cart or ecommerce platform connected to a compatible payment provider.
Customers select products, review shipping and taxes, and complete payment within an approved checkout process.
This approach is appropriate for businesses selling physical products, digital products, or services that customers purchase through a website.
Before selecting a gateway, confirm compatibility with your ecommerce platform, supported payment methods, refund workflow, order management, and existing software.
2. Hosted Payment Pages
A hosted payment page allows customers to complete a transaction on a payment page operated by a third-party provider.
The merchant may send the customer to that page from a website, invoice, or another approved payment process.
One potential advantage is that sensitive card information can be collected directly by the payment provider rather than passing through the merchant’s own servers.
Hosted pages may also be simpler to deploy than a fully customized checkout.
However, using a hosted page does not eliminate every merchant security obligation or automatically establish PCI compliance.
3. Embedded Payment Components
Some payment platforms allow secure payment fields or components to appear directly within a merchant’s website.
The customer can complete checkout without being redirected to a visibly different payment page.
Depending on the implementation, a compliant provider may tokenize card details in the customer’s browser so the merchant’s server does not receive raw payment information.
This arrangement can offer greater control over checkout design while limiting sensitive data exposure.
However, the website itself may still introduce security risks, including compromised scripts that redirect customers or interfere with payment collection.
For example, NMI’s Payment Component documentation describes an embedded payment interface that tokenizes supported payment details before processing through its API.
4. Online Payment Links and Electronic Invoices
A business that sends invoices may not need a shopping cart at all.
Where supported by the payment provider, an invoice or secure payment link lets the customer open an approved payment page and pay the amount due.
Consider an HVAC contractor who finishes a repair and emails the customer an itemized invoice.
The invoice may include an approved online payment option, allowing the customer to pay without calling the office to provide card information over the phone.
This can also be useful for consultants, accounting firms, professional services, and other invoice-driven businesses.
5. Virtual Terminals and Recurring Billing
A virtual terminal is a secure provider interface that allows an authorized business user to enter and process eligible transactions through a computer or other supported device.
It can be useful for businesses taking payments by phone or managing transactions without a physical terminal.
Because these are often manually entered, card-not-present transactions, the pricing, fraud exposure, and PCI requirements may differ from a standard ecommerce checkout.
Some gateways also offer recurring billing or tokenized card-on-file features, subject to the provider’s capabilities and applicable customer authorization requirements.
Comparing Online Payment Options
| Method | Good Fit For | Main Consideration |
|---|---|---|
| Ecommerce checkout | Online stores and self-service purchases | Shopping cart and gateway compatibility |
| Hosted payment page | Businesses wanting a provider-operated payment page | Customer flow and remaining PCI responsibilities |
| Embedded component | Integrated online checkout | Secure implementation and website maintenance |
| Payment links and invoices | Contractors and professional services | Invoicing, reconciliation, and customer communication |
| Virtual terminal | Authorized staff taking remote payments | Manual-entry costs and data-handling controls |
These options can overlap. For example, a payment gateway may support hosted checkout, virtual terminal transactions, invoices, and recurring payments within one platform.
Businesses should confirm the exact capabilities available through their selected provider and processing arrangement.
How Much Does Online Credit Card Processing Cost?
Online credit card processing fees vary by processor, card type, transaction characteristics, pricing structure, and merchant agreement.
Card-not-present transactions may carry different interchange or risk-related costs from eligible card-present transactions.
But there is no universal online processing rate that applies to every merchant.
Common Online Payment Processing Costs
Depending on the provider, charges may include:
- Percentage-based transaction processing fees
- Per-transaction authorization or processing charges
- Interchange and card-network assessments
- Payment gateway subscriptions or transaction fees
- Monthly account or software charges
- Fraud screening or account verification costs
- Chargeback or dispute administration fees
- Cross-border or currency-related fees
- Refund, reporting, or integration fees where applicable
Some providers bundle several of these expenses into one transaction rate. Others present separate charges.
Neither structure is automatically better. What matters is the total expense associated with your actual transactions.
Flat-Rate vs. Interchange-Plus Pricing
Flat-rate pricing generally charges a defined rate for transactions in a particular category, often expressed as a percentage plus a fixed amount.
Interchange-plus pricing generally passes through applicable interchange costs and adds an agreed processor markup, with other contractual fees potentially applying.
Interchange-plus can offer additional visibility into certain underlying transaction costs, but it is not guaranteed to be cheaper for every merchant.
A business processing a relatively small number of transactions may prefer simplicity. Another business with higher volume and a different card mix may benefit from a detailed pricing comparison.
An Illustrative Online Processing Fee Comparison
Imagine an online retailer processes $10,000 in card sales through 200 transactions during one month.
The average transaction is $50.
Example: $10,000 in Monthly Online Sales
Hypothetical Plan A: 2.9% + $0.30 per transaction
$10,000 × 2.9% = $290
200 transactions × $0.30 = $60
Total: $350
Hypothetical Plan B: 2.6% + $0.20 per transaction
$10,000 × 2.6% = $260
200 transactions × $0.20 = $40
Total: $300
Illustrative Difference: $50 per Month
These are hypothetical rates for arithmetic illustration, not actual VMS quotes, industry averages, or guaranteed savings. The comparison excludes additional charges, card-mix differences, and other contractual costs.
If Plan B also had a $35 monthly gateway fee that Plan A did not have, the hypothetical difference would fall to $15.
That is exactly why businesses should compare their complete processing arrangements rather than focusing on one advertised percentage.
If you already accept cards, reviewing several recent processing statements can help reveal the actual cost of your current arrangement. Our free processing rate review offers a way to evaluate those costs.
How Secure Is Online Credit Card Processing?
Online credit card payments can be processed through systems designed to protect sensitive information, but accepting payments online still requires attention to security.
The goal is to reduce unnecessary exposure of cardholder data, maintain appropriate protections, and understand the responsibilities shared between the merchant and its providers.
PCI DSS Applies to Online Merchants
The Payment Card Industry Data Security Standard (PCI DSS) establishes security requirements for environments that store, process, or transmit payment card information.
Outsourcing payment processing can reduce the systems and data a merchant must manage directly, but it does not automatically eliminate the merchant’s compliance responsibilities.
The PCI Security Standards Council explains that merchants remain responsible for understanding and overseeing the security obligations associated with their payment providers.
The appropriate compliance validation method depends on the specific checkout implementation and the requirements of the entity responsible for the merchant’s compliance program.
Hosted and Embedded Checkout Are Not Automatically Equivalent
A fully hosted payment page can change how payment information is collected and which systems are exposed to sensitive data.
An embedded payment component may allow the customer to remain on the merchant’s website while a compliant provider handles the card data.
But merchants using embedded components must pay attention to whether the surrounding website can be compromised by malicious scripts.
The PCI Security Standards Council’s SAQ A eligibility clarification explains the distinction between certain redirect arrangements and embedded third-party payment forms.
Additionally, certain external vulnerability-scanning requirements can apply to ecommerce merchants completing SAQ A, including those using outsourced payment pages. The merchant should confirm the exact applicable requirements with its acquirer or compliance provider.
Tokenization Helps Reduce Sensitive Data Exposure
Tokenization replaces sensitive payment data with a reference value that can be used for permitted payment operations.
For example, an approved payment provider may securely store the customer’s card details and provide a token for future authorized transactions.
The merchant’s software can reference that token without keeping the raw card number in its own database.
This can be useful for recurring billing, saved payment methods, and repeat customers.
However, tokenization does not eliminate all security responsibilities, and the implementation must still meet applicable requirements.
Fraud Screening and Authentication
Depending on provider capabilities, online merchants may have access to:
- Address Verification Service (AVS)
- Card verification code checks during authorization
- Transaction velocity and risk rules
- Device or behavioral risk information
- Supported EMV 3-D Secure authentication
- Transaction alerts and review procedures
These tools can help reduce particular types of fraud, but no tool guarantees that every transaction is legitimate.
Visa describes EMV 3-D Secure as a way for merchants and issuers to exchange information and authenticate cardholders during eligible online purchases. See Visa Secure for additional information.
Merchants should also avoid storing card verification codes after authorization, follow approved payment-data handling procedures, and keep websites and software properly maintained.
How to Improve Online Checkout and Reduce Payment Problems
A payment system should protect transactions without making the buying process unnecessarily difficult.
A confusing checkout can lead to abandoned orders, duplicate attempts, customer complaints, or transactions that require manual correction.
Make Checkout Work on Mobile Devices
Customers should be able to review the purchase, enter required information, and complete payment comfortably on a smartphone.
Test the actual checkout on mobile devices instead of assuming that a responsive website automatically provides a good payment experience.
Pay particular attention to form fields, required information, error messages, and the steps between cart review and confirmation.
Display the Total Before Payment
Customers should understand the complete amount they are authorizing.
Clearly present relevant product prices, shipping charges, taxes, and any other applicable charges before the customer submits payment.
For service providers, invoices should clearly identify the work performed, deposits, credits, and remaining amount due.
Send Useful Confirmation Messages
Once a payment has been successfully processed, provide a clear order or payment confirmation through an appropriate channel.
Depending on the business, include an order number, contact information, delivery expectations, or next steps.
A good confirmation process can reduce customer confusion and provide a useful record for future questions.
Handle Declines and Duplicate Attempts Carefully
A declined payment does not always mean the customer’s account lacks funds. The issuer or processor may decline a transaction for several reasons.
Use the provider’s supported error-handling tools and avoid instructing customers to submit the same payment repeatedly without checking whether a prior authorization exists.
For subscription businesses, determine whether the platform supports appropriate retry rules and customer notifications.
Understand Chargeback Exposure
Online payments are generally card-not-present transactions. Merchants should understand the fraud and dispute risks associated with that environment.
Proper authorization does not guarantee that a customer will not later dispute the charge.
Clear policies, accurate descriptions, delivery records, appropriate fraud controls, and accessible customer service can help reduce avoidable disputes.
For more detailed prevention strategies, read our guide on how to prevent credit card chargebacks.
When Do Merchants Get Paid for Online Credit Card Sales?
Online card transactions often receive an authorization response quickly, but moving the money into a merchant bank account involves additional steps.
After authorization and capture, the transaction moves through the applicable clearing and settlement processes.
The merchant’s provider then makes funds available according to the relevant account terms and funding schedule.
Authorization Is Not Funding
Suppose a customer places a $750 order and receives an order confirmation.
The payment may have been authorized, but the merchant may not yet have captured the payment or received settlement proceeds.
Some ecommerce systems authorize at checkout and capture later. Others support immediate sale processing.
The correct workflow depends on the business, the gateway configuration, and the processor’s requirements.
Funding Schedules Can Vary
Depending on eligibility and processing arrangements, merchants may have access to Instant, Same Day, or Next Day Funding programs.
However, these terms do not describe a universal schedule for every ecommerce account.
Batch cutoffs, weekends, banking holidays, settlement processing, underwriting requirements, holds, and reserves can affect actual availability.
Before selecting a provider, ask when completed online transactions are captured and when the proceeds are expected to reach the business bank account.
Reconcile Sales, Refunds, and Deposits
Reconciliation is especially important when a business processes online sales, refunds, chargebacks, and multiple payment types.
A useful reporting system should help the merchant connect individual transactions with batches, adjustments, fees, and deposits.
If the business also uses accounting or invoicing software, ask about supported integrations and how the system records gross sales, refunds, processing expenses, and net deposits.
Good reporting reduces the amount of time needed to identify differences between website orders and actual bank deposits.
Online Credit Card Processing Examples by Business Type
One of the most common mistakes is assuming that every business needs the same online payment setup.
Consider these examples.
Online Retail Stores
A retailer selling clothing, gifts, or other physical products may need a shopping cart integration, mobile-friendly checkout, order confirmations, shipping information, and appropriate fraud screening.
The system should also support refunds and provide records linking completed payments to individual orders.
Contractors and Home Service Businesses
An electrician, HVAC company, or remodeling contractor may primarily need online invoices and payment links rather than a public shopping cart.
The ability to collect approved deposits, send final invoices, and identify which customer paid each bill may be more valuable than advanced retail features.
Professional Service Firms
Accountants, consultants, and other professional firms may need secure online payments connected to invoices and accounting records.
Supported recurring billing, stored payment tokens, and reconciliation tools may be useful when working with established clients.
Businesses with specialized legal or accounting requirements should also verify that the platform supports their obligations.
Restaurants Offering Online Ordering
A restaurant taking online pickup or delivery orders may benefit from payments integrated with its ordering system or POS.
The key questions involve correct menu pricing, order status, tips, refunds, and reliable communication between online orders and the restaurant’s operations.
Membership and Subscription Businesses
Businesses offering memberships or recurring services may need approved card-on-file storage, customer authorization records, recurring transaction schedules, and a straightforward cancellation process.
Keeping renewal communications and billing records accurate can help prevent disputes and customer confusion.
The best system is the one that supports the real workflow without requiring the merchant to build unnecessary complexity around it.
How to Set Up Online Credit Card Processing
Getting started usually requires an approved processing arrangement, compatible technology, and procedures that match how the business will collect and manage payments.
Step 1: Identify Your Payment Needs
Determine how customers will pay.
Will they purchase products through a shopping cart, respond to invoices, make recurring payments, or provide card details to authorized staff?
Write down your current software, approximate monthly volume, average transaction amount, and expected payment methods.
Step 2: Review Your Current Website or Software
Check which payment integrations your ecommerce platform, invoicing system, or business software actually supports.
Don’t assume a gateway can connect to every shopping cart or accounting tool without additional development or fees.
Step 3: Compare Processing and Gateway Options
Evaluate the complete merchant agreement, not just the advertised rate.
Review transaction charges, monthly fees, supported payment methods, settlement schedules, fraud tools, contract terms, and customer support.
Step 4: Complete the Approval Process
The provider may require business registration information, ownership details, banking verification, estimated transaction volume, product or service information, and website details.
Some businesses may face additional underwriting requirements based on their operations, average ticket size, or fulfillment model.
Our merchant account documentation guide explains common information providers request.
Step 5: Configure Checkout and Security
Install or connect the approved payment solution using provider-supported instructions.
Verify which parts of the transaction are handled by the payment provider and which responsibilities remain with your business.
Review PCI requirements, customer-facing policies, supported authentication tools, and the procedures for protecting account access.
Step 6: Test the Complete Transaction Workflow
Follow the provider’s approved testing procedures.
Verify successful transactions, declines, refunds, order confirmations, transaction reporting, and any supported recurring payment features.
If you use a shopping cart, confirm that an approved transaction updates the order correctly and that a failed payment does not create a misleading completed order.
Step 7: Monitor Transactions and Reconcile Deposits
Once live processing begins, review payment activity regularly.
Confirm how sales, refunds, fees, chargebacks, and deposits appear in your reports.
Make sure employees know how to identify problems and contact the appropriate support team.
Questions to Ask Before Choosing an Online Payment Processor
Before committing to a new service, I recommend asking a few practical questions:
- Which ecommerce platforms and software integrations are supported? Ask about your specific version and setup, not just general compatibility.
- What are my total expected processing costs? Include gateway fees, transaction charges, monthly fees, and other applicable expenses.
- Who is responsible for merchant funding? Confirm the actual deposit schedule and possible holds.
- What security responsibilities remain with my business? Ask about PCI validation, payment-page protection, and provider responsibilities.
- What happens if a customer disputes a payment? Understand notifications, deadlines, evidence requirements, and fees.
- How are customer payment methods stored? Ask whether an approved tokenized system is available and how stored payment methods can be managed.
- Can I use my existing website and business software? Confirm integration costs, development requirements, and limitations before switching.
- Who helps when something stops working? Clarify whether support comes from the gateway, processor, software vendor, or another provider.
A good provider should be willing to explain the answers clearly and identify important limitations before a business signs an agreement.

Frequently Asked Questions About Online Credit Card Processing
1. What do I need to accept credit cards online?
You generally need a compatible payment solution, an approved processing arrangement, and a secure way for customers to submit payments. Depending on your business, this may involve ecommerce checkout software, a hosted payment page, payment links, or a virtual terminal.
2. Can I accept credit cards online without a website?
Yes. Some payment providers offer secure payment links, electronic invoicing, or virtual terminal services that allow eligible businesses to accept remote card payments without operating a full ecommerce storefront.
3. Is a payment gateway the same as a payment processor?
No. A payment gateway provides technology for securely collecting or routing payment information, while a processor helps move transaction requests through the card-payment infrastructure. Some providers combine these services into one offering.
4. Why can online credit card processing cost more than in-person payments?
Online payments are typically card-not-present transactions and can have different interchange and risk-related costs from eligible card-present transactions. Actual fees depend on the merchant agreement, card characteristics, processing model, and other factors.
5. How long does it take to receive money from online card payments?
An online card authorization can occur quickly, but capture, settlement, and merchant funding follow separate processes. Actual deposit timing depends on the provider, processing cutoff, banking schedule, account eligibility, and any applicable holds or reserves.
6. Does a hosted payment page eliminate PCI compliance requirements?
No. Outsourcing payment collection may reduce a merchant’s PCI scope, but remaining requirements depend on the integration and applicable compliance program. Businesses should verify their responsibilities with the provider and the organization managing their PCI compliance validation.
7. Can customers pay online using Apple Pay or Google Pay?
Some payment platforms support eligible digital wallets, including Apple Pay and Google Pay. Availability depends on the gateway, processor, ecommerce integration, device, and other requirements. Confirm support before selecting a solution.
8. Can I accept recurring online credit card payments?
Yes. Many payment providers offer eligible recurring billing services and tokenized card-on-file features. Businesses must follow applicable customer authorization, notification, card-network, and cancellation requirements.
9. Does Valued Merchant Services offer online credit card processing?
Yes. Valued Merchant Services offers access to ecommerce payment gateways, virtual terminals, and compatible online payment solutions. Specific features, pricing, integrations, and approval requirements depend on the selected provider and merchant arrangement.
Final Thoughts: Choose the Online Payment Setup That Fits Your Business
Online credit card processing creates opportunities for businesses to sell products, collect invoices, and accept customer payments beyond a physical checkout counter.
But the right setup is not determined by one payment button, software feature, or advertised processing rate.
It depends on how your customers purchase, how you deliver products or services, how payments connect to your existing systems, and when you need access to the proceeds.
Security, customer experience, reliable reporting, and responsive support all matter.
My recommendation is to compare the complete payment workflow before changing providers or committing to new technology.
Understand the fees. Confirm the integrations. Test the checkout. Ask about fraud and dispute tools. Verify your funding terms.
And remember that the best option may be a combination of technologies rather than one platform that attempts to do everything.
At Valued Merchant Services, we’ve helped business owners evaluate payment solutions since 2006. Our approach remains the same: put people before profits and recommend changes only when they make sense.
Good online payment processing should make it easier for customers to pay and easier for the business to operate. That’s the standard worth looking for.
