E-Commerce Payment Processing
Transparent pricing, built-in fraud protection, and gateway integrations for every major platform. Most online merchants on flat-rate processors are paying 0.5% to 1.0% more than they need to.
How E-Commerce Payment Processing Is Different
Online stores face a different set of payment processing challenges than brick-and-mortar businesses. Understanding them is the first step to building the right setup.
Every transaction through your online store is a card-not-present transaction. The customer is not standing in front of you, so there is no chip reader, no signature, no physical verification of any kind. That single fact changes almost everything about how payment risk and costs are structured for e-commerce merchants.
Card networks charge higher interchange rates on card-not-present transactions because the fraud risk is meaningfully higher than in-person transactions. A processor using flat-rate pricing bundles this cost into a single percentage that you pay regardless of whether a customer used a low-cost debit card or a premium rewards credit card. If your card mix skews toward debit or basic consumer cards, you are overpaying every month relative to your actual cost.
Higher Chargeback Risk
Card-not-present transactions have no physical signature or EMV chip authentication, making it easier for customers to dispute charges. E-commerce merchants typically see higher dispute rates than retail stores. A customer who does not recognize a charge on their statement, or who claims an item was not received, can initiate a chargeback without contacting you first. Chargeback management tools and proactive fraud screening are not optional for online stores.
Fraud Exposure
Stolen card numbers are most commonly tested and used online, where physical card authentication is not possible. Account takeover fraud, where criminals use stolen login credentials to place orders with saved payment methods, is also disproportionately an e-commerce problem. Without AVS, CVV verification, and optionally 3D Secure authentication, online stores are significantly more exposed to fraud-related chargebacks and the fees and ratio consequences that come with them.
Gateway and Platform Complexity
Unlike retail, where a terminal connects directly to a processor, e-commerce requires a payment gateway that sits between your website or shopping cart and your processor. Gateway choice affects which platforms you can integrate with, what fraud screening tools are available, and in some cases what pricing models are accessible. Choosing the wrong gateway for your platform can create technical headaches and limit your ability to switch processors without rebuilding your checkout.
Which Pricing Model Is Right for Your Online Store?
Not every pricing model works equally well for e-commerce. Here is how each one applies to online merchants.
| Pricing Model | How It Works for E-Commerce | Typical Effective Rate | Best When |
|---|---|---|---|
| Interchange Plus Recommended | You pay the actual card network interchange cost plus a fixed markup. Transparent, scalable, and passes debit savings directly to you. | Typically 1.9%–2.4% depending on card mix | Volume over $10K/month; meaningful debit or basic card usage |
| Flat Rate | Fixed percentage on every online transaction regardless of card type. Simple to predict but typically more expensive at meaningful volume. | Typically 2.7%–3.5% | Volume under $5K/month; predictability preferred over savings |
| Surcharging | Card-paying customers pay a surcharge of up to 3% on their purchase. Legal in most states; not permitted in Massachusetts or Connecticut. Requires card network registration. | Near $0 to merchant | Card-heavy customer base; compliant states; checkout flow supports surcharge disclosure |
| Cash Discounting | Your posted price is the card price. A lower price is available for ACH or check payments. Legal in all 50 states. Requires your checkout to support dual pricing display. | Near $0 to merchant on card transactions | High card volume; checkout platform supports dual pricing |
| Dual Pricing | Two prices are displayed at checkout: card price and cash/ACH price. Maximum transparency for customers. Eliminates processing fees while remaining legally compliant everywhere. | Near $0 to merchant | Checkout flows that can clearly display two prices without confusing the customer |
Effective rates are estimates based on a typical mix of consumer credit and debit cards. Your actual rate depends on your specific card mix, average ticket size, and merchant category code. Submit your statement for an exact comparison.
Required Features for E-Commerce Processing
These are the tools that separate a basic payment setup from one that actually protects and scales your online store.
Payment Gateway
A certified gateway (NMI, Authorize.Net, or Converge) connects your website or shopping cart to the processing network. Gateway choice determines which platforms you can use and what fraud tools are available. GoPayhawk supports all major gateways and helps you select the right one for your platform.
Fraud Screening
AVS and CVV verification on every transaction. Optional 3D Secure authentication for high-risk order profiles, which shifts fraud chargeback liability to the issuing bank. Velocity checks flag unusual order patterns like multiple card attempts from a single IP address or device.
Tokenization
Card data is replaced with a non-sensitive token at point of capture. Your servers never handle a real card number, which dramatically reduces your PCI compliance scope and eliminates the risk of card data theft from a server breach. Included by default with GoPayhawk processing.
Recurring Billing
For subscription businesses or any merchant with repeat customers. Automated recurring billing with failed payment retry logic, customer card update flows, and scheduled charge management. Pairs with subscription platforms like Chargebee for full subscription lifecycle management.
Chargeback Protection
Real-time dispute monitoring with early alerts before chargebacks become formal reversals. GoPayhawk's account managers help you respond to disputes with the right documentation and coach you on the specific reason code that was filed. Your chargeback ratio is monitored continuously.
International Card Acceptance
Accept cards issued outside the United States from customers shopping on your store. International cards carry slightly higher interchange rates. If a significant portion of your customers are international, your account manager can discuss currency configuration and cross-border optimization options.

What Your Processing Actually Costs
Most e-commerce merchants are on flat-rate pricing. Here is what that typically costs versus interchange-plus at a realistic monthly volume.
Example: Online Store, $30,000/Month, ~$65 Average Ticket
Assumptions: approximately 460 transactions per month, 70% credit cards / 30% debit cards, average credit interchange ~2.0%, average debit interchange ~0.8%.
Flat-rate processor (e.g., Stripe at 2.9% + $0.30):
2.9% of $30,000 = $870 + (460 transactions x $0.30) = $138
Total: approximately $1,008/month
GoPayhawk interchange-plus (avg ~2.2% all-in including markup and per-transaction fees):
2.2% of $30,000 = $660 + smaller per-transaction component
Total: approximately $700/month
Estimated monthly savings: approximately $308 — that is roughly $3,700 per year on this volume level.
These are illustrative estimates based on typical card mix averages. Your actual savings depend on your specific card mix, merchant category, and transaction profile. Submit your current statement for an exact side-by-side comparison.
The gap widens further if your store serves business buyers, accepts premium rewards cards, or processes international transactions, because flat-rate pricing treats all of these exactly the same. Interchange-plus pricing reflects the actual cost of each card type, which means you benefit when your customers use lower-cost payment methods.
If you are already on Stripe, PayPal, or Square, a statement analysis takes about 10 minutes and shows you the exact comparison before you commit to anything.

E-Commerce Payment Processing FAQ
GoPayhawk supports multiple gateways including NMI, Authorize.Net, Converge, and Cybersource. If you are already using Authorize.Net or NMI on your website, you can often keep your existing gateway and just change the underlying processor to GoPayhawk to get better rates. Your account manager will help identify the right gateway for your platform and transaction volume.
Yes. GoPayhawk supports Shopify through payment gateway integrations. Because Shopify requires merchants to use Shopify Payments or a supported third-party gateway, GoPayhawk connects via NMI or Authorize.Net. Your account manager will walk you through the specific setup for your store and confirm compatibility before you apply.
Interchange-plus is typically the best pricing model for e-commerce stores processing over $10,000 per month. It passes the actual card network cost through to you with a transparent fixed markup, so you benefit when customers use lower-cost cards like debit. Flat-rate pricing is simpler but typically more expensive at meaningful volume. Surcharging and cash discounting are also available for stores in compliant configurations.
GoPayhawk's processing infrastructure, powered by Elavon, includes real-time fraud screening on every transaction. For card-not-present transactions, AVS and CVV verification are standard. Your account manager can advise on 3D Secure authentication, which shifts fraud chargeback liability from you to the issuing bank when authentication succeeds. GoPayhawk also provides chargeback protection services that monitor your account and alert you early in the dispute cycle.
Yes. GoPayhawk supports recurring billing through gateway integrations and can pair with subscription management platforms like Chargebee. Recurring billing features include automated retry logic for failed payments, customer card update flows, and scheduled charge management. Your account manager will help configure the right gateway and billing setup for your specific subscription model.
Tokenization replaces a real card number with a randomly generated token at the point of capture, before data reaches your servers. If your systems are ever compromised, attackers only find tokens with no value outside the payment network. Tokenization also reduces your PCI compliance scope since your systems never handle actual card numbers. It is included by default with GoPayhawk processing.
Yes. GoPayhawk merchants can accept cards issued outside the United States. International card transactions typically carry slightly higher interchange rates than domestic cards. If a significant portion of your customers are international, your account manager can discuss currency and cross-border configuration to optimize your setup.
Standard e-commerce merchant account approval typically takes 24 to 48 hours. Once approved, gateway configuration and integration setup adds a few days depending on your platform and technical setup. Most merchants are live and accepting online payments within one week of starting the application. Your GoPayhawk account manager handles onboarding and coordinates with your technical team or platform provider.
