Processing Payment in 2026: A Founder's Guide

By Stefan Ciancio on 2026-06-05

TL;DR: Processing payment involves using a payment service provider like Stripe or a traditional merchant account to securely transfer funds from your customer to your bank. For most online businesses and startups, an all-in-one provider like Stripe is the best starting point due to its simplicity, while high-volume businesses can save money with a more complex merchant account and gateway setup.

Quick answers

What is the simplest way to start processing payments?

The simplest method is to sign up for a payment service provider (PSP) like Stripe or PayPal. They bundle the merchant account, payment gateway, and processing into one service with a straightforward, flat-rate fee structure. You can typically create an account and start accepting payments online within minutes, which is exactly what I did when I first started selling digital products and my book, Sell More With Webinars.

How much does it cost to process a payment?

Costs vary, but a standard online rate from providers like Stripe is 2.9% + $0.30 per transaction. This fee covers everything. Other models, like Interchange-plus, have lower percentage markups but add more complexity with variable interchange fees from card networks (Visa, Mastercard) and fixed monthly fees. We'll break this down in detail.

What is the difference between a payment processor and a payment gateway?

A payment processor executes the transaction, moving money between the banks. A payment gateway is the secure technology that connects your website's shopping cart to the processor, encrypting the customer's card details and sending the transaction request. All-in-one providers like Stripe act as both, simplifying the setup for you as the merchant.

Can I process payments without a website?

Yes. You can use payment links, email invoicing, QR codes, or a virtual terminal. Most modern processors provide tools to generate a shareable link that takes customers to a secure payment page. This is great for service businesses, coaching, or taking payments over the phone without needing a full ecommerce build-out.

What’s the best payment processor for a small business?

For most small businesses, especially those just starting, Stripe is a top choice due to its developer-friendly tools, predictable flat-rate pricing, and robust feature set. Square is excellent for businesses with both online and in-person sales. PayPal is also a popular choice because of its large user base, but be aware of its reputation for holding funds.

What is Payment Processing? The Core Mechanics

Let's demystify this. At its heart, processing a payment is the multi-step journey money takes from your customer's wallet to your business bank account. It feels instant, but there are several players working behind the scenes. When a customer clicks 'Buy Now' on your site, here's the chain reaction:

The Customer: Enters their credit or debit card details into your checkout page (which is powered by a payment gateway).
The Merchant: That's you. Your website sends the encrypted transaction details to the payment processor.
The Payment Gateway: Securely transmits the information from your website to the processor, ensuring card details are not exposed.
The Payment Processor: This is the company doing the legwork. They route the transaction request to the relevant card network (like Visa, Mastercard, or American Express).
The Card Network: The card network then contacts the bank that issued the customer's credit card.
The Issuing Bank: This is the customer's bank (e.g., Chase, Bank of America). It checks if the customer has sufficient funds or credit. It either approves or denies the transaction, sending a response back through the chain.
The Acquiring Bank: This is your business bank, also known as the merchant bank. If the transaction is approved, it receives the funds from the issuing bank (minus fees) and deposits them into your account.

This entire approval or denial process happens in about two seconds. The actual settlement of funds into your account takes longer, typically 1-3 business days. For my software company, WebinarKit, we see Stripe deposits hit our bank account on a two-day rolling basis. This entire ecosystem is why fees exist; every player in this chain takes a small piece of the pie for their role in making the transaction happen securely and reliably.

My First $10,000 Month: A Payment Processing Story

Before launching my 'big' ventures like WebinarKit or Maker AI, I was selling digital courses and my book online. My first real taste of significant volume came when I launched an info-product that hit $10,000 in its first month. I was using a combination of PayPal and Stripe. On one hand, it was exhilarating. On the other, it was a harsh introduction to the realities of fees and risk management.

My setup was simple: a sales page linked to a checkout. I chose Stripe because it was easy. The 2.9% + $0.30 fee felt abstract at first. But when I looked at my first big payout, the math became painfully clear. On $10,000 of revenue, I was paying around $320 in fees (a bit more than a flat $290 because of the per-transaction fee). That's the cost of a nice dinner out, or a few new software tools. It's a real business expense.

The bigger shock came from PayPal. They have a notoriously sensitive algorithm, and a sudden spike in sales from a new account can trigger a hold. About halfway through the month, they froze over $4,000 of my money, demanding invoices and proof of delivery for my digital product. It was a nightmare that took weeks to resolve. This taught me a critical lesson: never rely on a single payment processor. Redundancy is not a luxury; it's a necessity for business continuity. This early experience directly shaped how I structured the payment infrastructure for all my future businesses, which you can see in my portfolio of companies.

The True Cost of Processing Payments: Deconstructing the Fees in 2026

"It's just 2.9%" is a dangerous simplification. Understanding where your money goes is the first step to optimizing costs. There are three main components to any card transaction fee:

Interchange Fee: This is the largest portion of the fee, typically 1.5% to 2.5%. It goes directly to the customer's issuing bank to cover the risk and rewards programs. These rates are non-negotiable and set by the card networks (Visa, Mastercard). They vary based on card type (debit vs. credit, rewards vs. standard), and transaction method (in-person vs. online).
Assessment Fee: A smaller fee, around 0.13% to 0.15%, that goes to the card network itself (Visa, etc.) for using their network. This is also non-negotiable.
Processor Markup: This is the only negotiable part of the fee. It's what your payment processor (Stripe, a merchant account provider, etc.) charges for their service.

There are two primary pricing models you'll encounter:

Flat-Rate Pricing: Used by Stripe, PayPal, and Square. They bundle all three fees into a single, predictable rate (e.g., 2.9% + $0.30). You pay for simplicity and convenience.
Interchange-Plus Pricing: Used by traditional merchant account providers. They pass the non-negotiable Interchange and Assessment fees directly to you and add a fixed, transparent markup. It might look like "Interchange + 0.20% + $0.10". This is more complex but almost always cheaper for businesses processing over $10k-$20k per month.

Fee Breakdown: $100 Online Transaction Example

Component	Stripe (Flat-Rate)	Merchant Account (Interchange-Plus)
Interchange Fee (e.g., 1.8%)	Bundled into one fee: $2.90 + $0.30	$1.80
Assessment Fee (e.g., 0.14%)		$0.14
Processor Markup (e.g., 0.25% + $0.10)		$0.25 + $0.10
Total Cost	$3.20	$2.29

As you can see, the savings on the Interchange-Plus model become significant at scale. On $100,000 in monthly sales, that's a difference of nearly $1,000. It's why I created ProcessingScoop, a comparison site to help founders easily compare these different models and find the best fit without needing a finance degree.

Stripe vs. PayPal vs. The World: Choosing Your Processor for 2026

Choosing your primary processor is a foundational business decision. Your choice impacts cash flow, customer experience, and your bottom line. Here's my take on the main players, based on years of direct experience.

Stripe: The Default for Modern Online Business
Stripe is my go-to recommendation for most startups, SaaS companies, and online businesses. We use it as the primary processor for WebinarKit. Their API is second to none, making integration a dream for developers. Documentation is clean, the dashboard is intuitive, and features like Stripe Billing (for subscriptions), Radar (for fraud detection), and Connect (for marketplaces) are best-in-class.

Pros: Predictable flat-rate pricing, quick setup, excellent developer tools, strong feature set.
Cons: Higher cost at scale compared to Interchange-Plus. Customer support can be slow and robotic unless you're on a premium plan.

PayPal: The Necessary Evil
PayPal has massive brand recognition and user trust. Offering PayPal as a checkout option can genuinely boost conversion rates, because some customers prefer it or don't have their credit card handy. However, as a primary processor, I advise caution. My story of having funds frozen is not unique. Their risk algorithms are aggressive, and getting a human on the phone to resolve an issue can be infuriating. We offer it as a secondary payment option, but it never serves as our core processor.

Pros: High customer trust, can increase conversion, simple for customers.
Cons: Notorious for freezing accounts and holding funds, especially with sales spikes. Fees are comparable to Stripe, but the service is less reliable for merchants.

Traditional Merchant Accounts: The Scale-Up Option
Once your business is consistently processing over $20,000-$30,000 a month, it's time to explore a traditional merchant account with Interchange-Plus pricing. Providers like Helcim or those found through comparison sites offer significant cost savings. The trade-off is a more involved application process (they'll do real underwriting on your business) and a less-sleek tech interface. You'll also need a separate payment gateway, like Authorize.net, to connect the merchant account to your website. It adds a layer of complexity but directly impacts your profit margin. For my high-volume businesses, this is a path we've seriously explored to optimize costs.

Pros: Significantly cheaper at scale, more direct relationship with the provider, often better customer service.
Cons: Lengthier setup process, less-friendly technology, often requires a separate gateway.

High-Risk vs. Low-Risk: Why Your Business Type Matters

Not all businesses are created equal in the eyes of payment processors. They categorize you as either low-risk or high-risk, which dramatically affects your fees and even your ability to get an account. The primary factor is the likelihood of chargebacks.

Low-Risk Businesses are typically brick-and-mortar retail stores with in-person transactions, or simple ecommerce stores selling physical goods with a short delivery window. Chargeback rates are usually very low.

High-Risk Businesses include industries like:

SaaS (Software-as-a-Service)
Digital products and information marketing
Travel and event ticket sales
Subscription boxes
Anything with recurring billing or long fulfillment times

My companies, WebinarKit (SaaS) and Epic Marketing Events (event tickets), fall squarely into the high-risk category. Why? Because the 'product' isn't delivered instantly. A customer might buy a yearly subscription to WebinarKit and file a chargeback eight months later. Or they buy a ticket to an event six months away and their plans change. Processors see this as a huge liability.

Being classified as high-risk means a few things:

Higher Fees: Expect to pay a premium. Your Interchange-Plus markup will be higher, or you may be rejected by standard providers like Stripe altogether.
Rolling Reserves: The processor might hold a percentage of your revenue (e.g., 10%) for a rolling period of 90-180 days to cover potential future chargebacks. This can be a major cash flow constraint.
Stricter Underwriting: You'll need to provide more documentation about your business history, processing history, and fulfillment process.

If you're in a high-risk industry, you may need to work with a specialized high-risk processor. Dealing with this is a cost of doing business in these lucrative fields. Honesty during your application is critical; trying to hide the nature of your business will only lead to a sudden account closure down the line.

Chargebacks: The Silent Killer of Profit Margins

A chargeback is a forced transaction reversal initiated by the customer's bank. It's not a simple refund. It's a costly, time-consuming dispute that you, the merchant, are presumed guilty in until you prove your innocence. When we first scaled WebinarKit, our chargeback rate crept up to a terrifying 1.5%. For context, most processors have a threshold of 1%. Exceeding it puts you on a path to account termination.

Each chargeback costs you not only the original transaction amount but also a separate, non-refundable chargeback fee of $15-$25. Fighting them requires submitting compelling evidence: proof of delivery, customer communications, usage logs, and terms of service agreements. It's a massive operational drag.

We got our rate under 0.5% with a multi-pronged approach:

Clear Communication: Our billing descriptor is crystal clear: 'WEBPILOT, INC. for WEBINARKIT'. No more confused customers wondering what a charge is for.
Proactive Support: We make it incredibly easy for customers to request a refund. A visible support email and quick response times are cheaper than a chargeback every time.
Robust Evidence Gathering: For SaaS, we log every single user login, key feature usage, and IP address. When a customer claims they 'never used the service', we can provide a detailed report to the bank showing otherwise. I used this exact method to win a dispute for a $999 annual plan just last month.
Using Fraud Tools: We use Stripe Radar's advanced settings to block suspicious transactions from high-risk locations or cards that fail AVS (Address Verification System) checks.

Don't take chargebacks lightly. They are a direct threat to your profitability and your ability to process payments at all. Check out my blog for more deep dives into operational challenges like this.

A 5-Step Checklist for Setting Up Your Payment Processing

Getting started can feel overwhelming. Here's a simple, actionable framework to follow:

Analyze Your Business Model: Are you online-only, in-person, or hybrid? Is it a one-time purchase or a recurring subscription? Is your industry considered high-risk? Answering these questions narrows your choices immediately. Don't pick a processor built for coffee shops if you're a SaaS founder.
Estimate Your Monthly Volume: Be realistic. If you're starting out and expect less than $10,000/month, the simplicity of a flat-rate provider like Stripe is worth the slightly higher fee. If you're migrating an existing business with $50,000/month in sales, your top priority should be getting Interchange-Plus quotes.
Compare Your Top 2-3 Options: Don't just go with the first name you recognize. Create a shortlist. Read reviews, but with a grain of salt. For a real, data-driven comparison, use a tool like ProcessingScoop to see a transparent breakdown of fees and features. Look at contract terms, payout schedules, and integration capabilities.
Prepare Your Documentation: To get a merchant account, you'll need basic business info: your Employer Identification Number (EIN), business license, a business bank account, and potentially a voided check. Having this ready will speed up the application process immensely.
Integrate and Test Thoroughly: Once approved, the final step is integration. Whether you use a simple plugin for WooCommerce or a full API integration for your custom platform, test it rigorously. Run a few small, real transactions. Test your refund process. Ensure everything works smoothly before you start driving major traffic to your checkout.

When to Scale Beyond a Single Processor

Relying on a single processor is a single point of failure. As I learned the hard way with PayPal, an unexpected account freeze can halt your entire operation. For any business processing significant volume, a multi-processor strategy is smart risk management.

At WebinarKit, while Stripe is our primary, we maintain a secondary processor as a hot backup. If Stripe were to have a major outage or freeze our account for any reason, we could switch our traffic over to the backup processor within an hour. This isn't just a 'what if' scenario; I've seen founder friends get their primary accounts shut down overnight during a big launch with no explanation. They lost hundreds of thousands in sales because they had no Plan B.

Beyond redundancy, a multi-processor setup can also save you money. You can route certain types of transactions to the processor that offers the best rate for them. For example:

Use a processor that specializes in international payments for non-US customers to get better currency conversion rates.
Route American Express transactions through a processor that offers a lower markup for AmEx, which often has higher base fees.

This is an advanced strategy, often managed by a payment orchestration layer, but it's the natural evolution for a business scaling past the seven-figure mark. The initial goal is survival and simplicity. The long-term goal is optimization and resilience. A great place to look at tools to help with this is my regularly updated tools page.

FAQ

What is the cheapest way to process credit card payments?

For businesses with significant volume (over $10k/month), an Interchange-Plus pricing model from a traditional merchant account provider is usually the cheapest. For new or low-volume businesses, a flat-rate provider like Stripe offers competitive value without the complexity of monthly fees or a long-term contract.

Can you get a merchant account with bad credit?

It is more difficult but not impossible. You will likely be considered high-risk. Providers may require a rolling reserve (holding a percentage of your funds) or a co-signer on the account. Be prepared for higher fees and stricter terms. Full transparency during the application process is key.

How long does it take for a payment to process?

The authorization (approval or decline) of a transaction happens in about 1-3 seconds. The settlement, which is the process of the money actually moving from the customer's bank to your merchant account, typically takes 1-3 business days depending on your processor and business history.

Do I need an LLC to process payments?

No, you can process payments as a sole proprietor using your Social Security Number instead of an EIN. However, forming an LLC or corporation is highly recommended to protect your personal assets from business liabilities. Most processors, like Stripe, easily accommodate both sole proprietors and formal business entities.

What are the most common reasons for a declined payment?

The most common reasons are insufficient funds, incorrect card information (number, expiration date, CVV), a fraud alert from the customer's bank, or the card being reported lost or stolen. Technical issues with the payment gateway or processor can also cause declines, though this is less common.

Which payment processor has the best customer support?

Generally, traditional merchant account providers who assign you a dedicated account representative offer the best, most personalized customer support. Among the large 'all-in-one' platforms, support can be a mixed bag. Stripe's support improves if you're on a higher-priced custom plan, while PayPal's is notoriously difficult to navigate.

How does processing payment for SaaS differ from ecommerce?

SaaS payment processing involves managing recurring billing, subscription tiers, prorations, and dunning (handling failed payments). This complexity makes a platform like Stripe with its robust 'Billing' feature a strong choice. Standard ecommerce is often focused on single, one-time transactions, which is simpler to manage.
