The Payment Processing Process Explained for 2026

By Stefan Ciancio on 2026-06-03

TL;DR: The payment processing process is a multi-step journey where a customer's payment information is securely captured, authorized by their bank, and transferred to your bank account. This involves several key players: a payment gateway, a payment processor, card networks (like Visa), and the banks, all working to move money from your customer to you in a process that takes seconds for approval and 1-3 days for settlement.

Quick answers

What are the 4 main steps of payment processing?

The four core steps are Authorization, Authentication, Clearing, and Settlement. Authorization is the initial approval or denial of the card. Authentication verifies the cardholder's identity to prevent fraud. Clearing is the process of sending transaction data in a batch to the card networks. Settlement is the final step where the money is actually moved from the customer's bank to your merchant account.

Who are the main players in the payment processing process?

There are typically six key players: the Customer (cardholder), the Merchant (you), the Acquiring Bank (your bank or processor), the Card Network (Visa, Mastercard, etc.), the Issuing Bank (the customer's bank), and the Payment Gateway (the technology that securely connects your website to the processor). Each plays a distinct and crucial role in making the transaction happen securely.

How long does the payment processing process take?

The customer-facing part is nearly instant. Authorization and authentication happen in about 1-3 seconds after a customer clicks 'buy'. The backend process, however, takes longer. Clearing and settlement happen in batches, so it typically takes 1 to 3 business days for the funds from a sale to actually appear in your bank account and be available to withdraw.

What is a payment gateway vs. a payment processor?

Think of it like this: the payment gateway is the secure credit card terminal on your website. It encrypts the card data and sends it for approval. The payment processor is the entity working behind the scenes with the banks and card networks to actually handle the transaction and move the money. Some companies, like Stripe and PayPal, act as both a gateway and a processor.

What are typical payment processing fees in 2026?

Fees are a mix of three parts: Interchange (paid to the customer's bank), Assessments (paid to the card network), and the Processor's Markup. This results in a total cost typically ranging from 1.5% to 3.5% of the transaction value plus a small fixed fee. For example, a standard online transaction might cost you 2.9% + $0.30. I built a whole tool to compare these over at ProcessingScoop because the rates can be so opaque.

Unpacking the Jargon: Gateway vs. Processor vs. Merchant Account

When I first started my entrepreneurial journey, long before WebinarKit or Maker AI, the world of payments was a black box. The terminology is designed to be confusing- Gateway, Processor, Merchant Account, Acquirer. Here’s the simple breakdown I wish I had. A Payment Gateway is the technology layer. It’s the digital equivalent of a physical credit card swipe terminal. It sits on your website's checkout page, encrypts the customer's data for security (this is PCI Compliance), and sends it off for approval. Think of it as the secure messenger.

The Payment Processor is the company that does the heavy lifting. They receive the encrypted data from the gateway and communicate with the card networks (Visa, Mastercard) and banks to approve or decline the transaction. They handle the entire transaction flow. Companies like Stripe or PayPal often bundle these services, acting as both gateway and processor, which is why they are so popular with startups.

Finally, a Merchant Account is a special type of bank account that allows you to accept credit and debit card payments. When a transaction is settled, the funds land here before being transferred to your main business checking account. With integrated providers like Stripe, this is part of their service- the Stripe balance you see *is* your merchant account. For more traditional setups, you might have a separate merchant account with a bank like Chase or Wells Fargo, and then use a separate gateway and processor. We used this traditional model for one of our Epic Marketing Events to get lower rates on high-volume ticket sales, but for the convenience and developer-friendliness of my software businesses like Maker AI and PressPitch AI, an all-in-one like Stripe is a no-brainer.

The 6 Key Players in Every Single Transaction

Every time a customer buys a copy of my book, Sell More With Webinars, or subscribes to WebinarKit, a complex dance happens between six key players. It's so fast, you never see it, but understanding the roles is critical to troubleshooting issues and lowering costs.

The Customer (Cardholder): The person with the credit card who wants to buy your product. Their goal is a simple, fast, and secure checkout.
The Merchant (You): Your business. You want to accept the payment securely, with low fees and a low risk of fraud.
The Payment Gateway: As we discussed, this is the technology that securely captures the card details from your website.
The Acquiring Bank (or Acquirer): Your business's bank or processing partner. They take the transaction details from the gateway and route them to the card network. They are on *your* side of the transaction and provide your merchant account.
The Card Network: The highways of the payment world. This is Visa, Mastercard, American Express, and Discover. They don't issue cards or accounts, but they set the rules and transfer the data between the acquirer and the issuer. They also charge a small fee, called an assessment, on every transaction.
The Issuing Bank (or Issuer): This is the customer's bank- the one that issued them their credit card (e.g., Bank of America, Capital One). They are responsible for approving or declining the transaction based on the customer's available funds and fraud risk. They are the ultimate decision-maker on their cardholder's behalf.

Think of it as a relay race. The customer hands the baton (their card info) to the gateway, who passes it to your acquirer, who runs it down the card network highway to the issuing bank. The issuing bank gives a thumbs-up or thumbs-down, which travels all the way back down the line in seconds.

Step-by-Step: The Authorization & Authentication Journey

Let's get into the nitty-gritty. A customer is on the WebinarKit checkout page, ready to sign up. They enter their card number, expiration date, and CVC, and click 'Complete Purchase'. In the next two seconds, this is what happens. First is **Authorization**. The encrypted payment details, along with the purchase amount, zip from the payment gateway to the processor. The processor then routes this request through the correct card network (e.g., Visa) to the customer’s issuing bank. The issuing bank's systems perform lightning-fast checks: Does the account exist? Is the card reported stolen? Is there enough credit or funds available? Is this transaction pattern unusual for this customer? Based on these checks, the issuing bank sends back an approval or a decline code. This whole round trip is the authorization process.

Running parallel to this is **Authentication**. This is the fraud-prevention step. You’ve probably seen it as a customer - a little box pops up asking you to enter a code sent to your phone, or to log into your banking app to approve a purchase. This is called 3D Secure (e.g., 'Verified by Visa' or 'Mastercard SecureCode'). As a merchant, implementing 3D Secure is a game-changer. For my SaaS businesses, it dramatically reduces fraudulent chargebacks. The beauty of it is that if a transaction is authenticated with 3D Secure, the liability for any resulting fraud shifts from me (the merchant) to the issuing bank. It adds a tiny bit of friction for the customer, but it has saved us tens of thousands of dollars a year in fraud losses and dispute fees at WebinarKit. It's a non-negotiable for any serious online business in 2026.

From 'Approved' to 'Paid': The Clearing & Settlement Process

The 'Approved' message your customer sees is just the beginning. You've secured the authorization, but you don't have the money yet. That comes next in the clearing and settlement phases. Think of it this way: authorization is a single, real-time conversation. Clearing and settlement is a batch process that happens later, usually overnight. At the end of the business day, you (or your processor automatically) will 'close the batch'. This means all your approved authorizations for that day are bundled together and sent by your processor through the card networks to the respective issuing banks.

This is the **Clearing** phase. During this process, the card networks act as the central clearinghouse, exchanging the transaction data between all the acquiring banks and all the issuing banks. They sort everything out, determining who owes what to whom. Following clearing, **Settlement** occurs. This is the actual movement of money. The issuing banks transfer the funds for all the cleared transactions to the acquiring banks, minus their interchange fees. Your acquiring bank then receives these funds, takes out their processing fee, and deposits the remaining amount into your merchant account. This entire clearing and settlement cycle is why it takes 1-3 business days for money from a sale to land in your account. For my business, this delay is a critical cash flow consideration. When we run a major launch for Maker AI, we might process $100,000 in a day, but I know I can't touch that cash for a couple of days. It's a fundamental part of financial planning that new entrepreneurs often overlook.

The Fee Stack: Where Your Money Really Goes

This is the part that drives most founders crazy. You see 2.9% + $0.30 and think that’s the end of it. It’s not. That fee is a bundle of three distinct costs, and understanding them is the first step to lowering them. Let's break down a hypothetical $100 online sale on a standard Visa rewards card.

Interchange Fee (~1.80% + $0.10): This is the largest chunk of the fee, making up about 70-80% of the total cost. It goes directly to the customer's issuing bank (e.g., Capital One). Why? It's their fee for taking on the risk of the transaction (fraud, defaults) and for the 'perk' of the rewards program on the card. This fee is non-negotiable and set by the card networks. A premium rewards card has a higher interchange fee than a basic debit card. For our $100 sale, this is about $1.90.
Assessment Fee (~0.15%): This is a smaller fee paid directly to the card network (Visa, in this case). It’s their charge for using their network. This is also non-negotiable. For our $100 sale, this is about $0.15.
Processor Markup (~0.95% + $0.20): This is the only part of the fee that's negotiable and goes to your payment processor (like Stripe, or a traditional processor). This is their profit and their cost of doing business- building the software, providing support, managing risk. In our flat-rate 2.9% + $0.30 example, this would be the remaining $0.85 + $0.20 = $1.15.

So on a $100 sale with a 2.9% + $0.30 fee, your total cost is $3.20. Of that, $1.90 went to the customer's bank, $0.15 went to Visa, and $1.15 went to your processor. When you process millions of dollars a year as we do across our portfolio, you start looking for ways to trim that markup. This is where pricing models like Interchange-Plus come in, where you pay the raw Interchange and Assessment costs plus a small, fixed markup. It's more complex but almost always cheaper at scale.

Choosing Your Processor: Stripe vs. PayPal vs. The World

Choosing your payment processor is one of the most critical early decisions for a business. The right choice can accelerate your growth; the wrong one can strangle it. I've used nearly every major platform across my businesses.

Stripe: This is my default for any new SaaS or software project. WebinarKit, Maker AI, and PressPitch AI are all built on Stripe. Their APIs are best-in-class, making it incredibly easy for developers to integrate payments, subscriptions, and complex billing logic. The documentation is pristine. Their ecosystem of tools like Stripe Radar for fraud, Stripe Billing for subscriptions, and Stripe Connect for platforms is unmatched. The downside? Their standard pricing (2.9% + $0.30) is not the cheapest. Once you hit scale (over $1M/year), you can and should negotiate a custom rate, but for starting out, you're paying a premium for convenience and developer experience. It's a price I'm happy to pay.

PayPal: I see PayPal as a necessary addition, not a primary processor. We offer it as a checkout option alongside Stripe. Why? Trust and conversions. For a certain segment of the population, particularly older or international buyers, the PayPal brand carries immense trust. They'd rather log into PayPal than type their credit card into a site they've never heard of. Adding PayPal as an option has consistently boosted our conversion rates by 5-10% on initial sales. However, I would never build my entire business on PayPal. Their funds-holding policies can be sudden and severe, and their backend is less flexible for complex subscription models than Stripe.

Traditional Merchant Accounts (e.g., via Fiserv, TSYS, or a bank): For our live events brand, Epic Marketing Events, we sometimes deal with very large transaction volumes in short bursts. For this, a traditional merchant account with Interchange-Plus pricing can be significantly cheaper. The trade-off is a clunky onboarding process, older technology, and less developer-friendly tools. It feels like banking from a decade ago. But when you’re processing hundreds of thousands in ticket sales, saving 0.5% is real money. This is an option to explore once your volume is high and your billing model is simple (e.g., not complex SaaS subscriptions).

Processor Selection Checklist

Here's a simple framework to help you decide:

Factor	Stripe	PayPal	Traditional Merchant Account
Best For	SaaS, platforms, tech startups, businesses prioritizing developer experience.	E-commerce conversion boost, simple products, international audiences.	High-volume retail or simple e-commerce businesses focused purely on lowest rate.
Pricing Model	Flat-rate (negotiable at scale).	Flat-rate.	Interchange-plus (usually).
Ease of Setup	Excellent. Minutes to get started.	Excellent. Very fast.	Poor. Days or weeks, lots of paperwork.
Developer APIs	Gold standard.	Good, but can be complex.	Often outdated or non-existent. Requires separate gateway.
Support	Good, but can be slow to reach a human for small accounts.	Notoriously difficult.	Varies wildly, can be good if you have a dedicated rep.

High-Risk Processing: When Standard Processors Say 'No'

Not all businesses are created equal in the eyes of a payment processor. When we first launched some of our digital products, I was shocked to learn we were considered 'high-risk'. Why? The term applies to industries with high chargeback rates. This includes businesses selling digital goods, supplements, travel, coaching, and yes, webinars and marketing training. The entire model for my book, Sell More With Webinars, is based on an industry that processors are wary of. Standard processors like Stripe or PayPal might onboard you initially, but a sudden spike in sales or a few chargebacks can get your account frozen or shut down with little warning.

A business might be labeled high-risk for several reasons: the industry (as mentioned), the business model (e.g., recurring billing for a service delivered in the future), high average transaction values, or selling to international customers in certain regions. If you fall into this category, you need a specialized high-risk processor. These processors understand your industry and have banking relationships that are comfortable with the increased risk. The downside is that you will pay a premium. Expect rates to be anywhere from 1% to 3% higher than a standard processor. You may also face other requirements, like a rolling reserve, where the processor holds a percentage (typically 5-10%) of your revenue for a period of time (usually 90-180 days) to cover potential chargebacks. It's a tough pill to swallow, but it's better than having your entire business shut down overnight. If you're in a high-risk industry, be upfront and find a specialist processor from day one. Don't try to sneak by on a standard platform- they will find you, and it will be painful.

Chargebacks: The Silent Killer of Online Businesses

Let me be direct: chargebacks are a plague. They are not just a refund. A chargeback is a forced reversal of a transaction initiated by the customer's bank. For every chargeback you receive, you not only lose the original sale amount, but you also get hit with a separate dispute fee, which is typically $15 to $25. Worse, your chargeback ratio (chargebacks as a percentage of total transactions) is tracked by the card networks. If it goes above a certain threshold (usually 0.9%), your processor can terminate your account. It's a huge threat to the stability of any online business, especially SaaS like WebinarKit.

We've fought thousands of chargebacks over the years, and I've learned that prevention is 90% of the battle. The best strategies are surprisingly simple. First, have crystal-clear billing descriptors. The text that appears on a customer's credit card statement should be your company name, not some obscure legal entity. Second, have easily accessible, top-notch customer support. Most chargebacks happen because a customer can't figure out how to get a refund or cancel a subscription. Make it easy for them to talk to you. Third, send clear post-purchase receipts and pre-renewal reminders for subscriptions. Surprise charges are a huge driver of 'friendly fraud' chargebacks.

When you do get a chargeback, you have to fight it, especially if it's for a digital product that has been accessed or used. We've built an entire internal process for this. We submit evidence showing the customer's IP address, login records, usage data, and proof they agreed to the terms of service. We use my AI content tool, Maker AI, to help standardize and generate the first draft of our evidence submissions. Despite our best efforts, we only win about 60-70% of the cases we fight. It’s a frustrating and costly part of doing business online, and a topic I cover in more depth on my blog.

Stuck on choosing a processor? The hidden fees and complex pricing are confusing. I built ProcessingScoop to give founders a transparent way to compare real-time, custom quotes from leading payment processors. Stop overpaying. Start comparing.

Go Global: The Complexities of International Payments

The moment you put a website online, you have a global business. But being able to *sell* globally requires thinking through the payment processing process for international customers. Simply letting them pay in USD with their Visa card is the bare minimum. True global selling means localization. When we expanded WebinarKit's marketing, we saw significant demand from Europe and Asia. Our initial checkout supported USD only, and our conversion rates in those regions were subpar.

The first step was implementing multi-currency support. Modern processors like Stripe make this relatively easy. We could show prices in Euros (€), British Pounds (£), and Australian Dollars (A$) and settle the payments in those currencies. This alone boosted conversions, as customers are always more comfortable paying in a currency they know. But it's not just about the currency; it's about the payment method. In the Netherlands, iDEAL (a bank transfer system) is more popular than credit cards. In Germany, it's Giropay or SEPA Direct Debit. In China, it's WeChat Pay and Alipay. Ignoring these local payment methods means leaving a huge amount of money on the table.

Integrating these adds complexity. Each has its own fee structure and settlement process. You also have to deal with currency conversion fees. When you settle a sale in EUR but your main bank account is in USD, the processor will convert it for you, usually for a fee of around 1-2% on top of the wholesale exchange rate. This can eat into your margins if you're not careful. For any business with significant international ambition, choosing a processor with a robust, built-in global payments platform is essential. It's one of the key tools in our growth stack.

The Future is Now: Emerging Trends in Payment Processing for 2026

The payment landscape never stands still. As an operator, I'm always looking at what's next to gain a competitive edge or reduce friction. For 2026, there are a few key trends I'm tracking for my own businesses. First, AI's role in fraud detection is becoming incredibly sophisticated. It's moving beyond simple rules-based systems to true behavioral analysis, understanding a customer's normal spending patterns and flagging deviations in real time. This allows for more accurate fraud prevention with fewer false positives- meaning more good customers get through without friction.

Second, real-time payments are finally becoming a reality in the US with systems like FedNow. While card transaction settlement still takes days, these new networks promise instant bank-to-bank transfers. The initial use cases will be for payouts and B2B transactions, but I expect to see this trickle down to consumer payments, potentially challenging the card networks on certain types of transactions over the next five years. Imagine getting paid instantly, not in 2 days. That's a massive cash flow win.

Finally, Buy Now, Pay Later (BNPL) services like Klarna and Afterpay are no longer just for e-commerce sites selling fashion. They are becoming a standard feature embedded within payment processors. For higher-priced software or training, offering a BNPL option can significantly increase conversions by breaking a large upfront cost into smaller, more manageable payments. It's an option we're actively testing for some of our higher-tier offerings at Epic Marketing Events. The future of payments is about being faster, smarter, and more flexible for both the merchant and the customer.

FAQ

What's the difference between flat-rate and interchange-plus pricing?

Flat-rate pricing (e.g., 2.9% + $0.30) bundles all fees into one simple rate. It's predictable but often more expensive. Interchange-plus pricing passes the non-negotiable interchange and assessment fees directly to you and adds a small, fixed processor markup. It's more transparent and cheaper for businesses with high volume, but less predictable month-to-month as interchange fees vary.

Can I negotiate payment processing fees?

Yes, but you need leverage. That leverage is processing volume. Once your business is consistently processing over $50k-$100k per month, you are in a position to negotiate your processor's markup. With flat-rate providers like Stripe, this usually requires processing over $1 million annually. Don't be afraid to shop your volume around to get competitive quotes.

What is a rolling reserve and why do I have one?

A rolling reserve is a risk-management tactic used by processors, especially for 'high-risk' businesses. They hold a percentage of your daily sales (e.g., 10%) for a set period (e.g., 180 days) on a rolling basis. This creates a cash buffer for the processor to cover potential future chargebacks. It's a major cash flow constraint, but often unavoidable in certain industries.

How does PCI compliance fit into the payment processing process?

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security rules for handling credit card data. Your payment gateway and processor must be PCI compliant. By using a modern, hosted checkout solution from a provider like Stripe, you are outsourcing most of your PCI compliance burden, as you never directly handle or store the raw card number on your servers.

What happens if a customer's payment is declined?

When a payment is declined, the issuing bank sends back a decline code. It could be for insufficient funds, a suspected fraud warning, an incorrect card number, or many other reasons. Your website should show a user-friendly message asking them to check their details or try another card. It's crucial not to just show a generic 'error' message.

Why did my payment processor suddenly shut down my account?

The most common reasons are a spike in chargebacks above the network threshold (0.9%), a sudden, unexplained spike in processing volume that looks like fraud, or selling products/services that violate their terms of service. This is why it's critical to understand your processor's rules and maintain open communication if you're planning a big launch.

Are 'instant payouts' really instant?

Mostly, yes, but with a cost. Services like Stripe Instant Payouts use debit card networks to push funds to your bank account in minutes rather than waiting 1-3 days for standard settlement. However, they charge a fee for this privilege, typically 1%-1.5% of the payout volume. It's a great tool for urgent cash flow needs but expensive if used regularly.
