The Right Payment Gateway for Your Ecommerce Store
Your gateway controls tokenization, recurring billing, fraud rules, and platform integration. Pick the wrong one and you're stuck — pick the right one and switching processors becomes painless.
A payment gateway is the layer between your checkout and your processor. It tokenizes card data, applies fraud rules, supports recurring billing, and routes transactions to the acquiring bank. The big benefit of a standalone gateway: it sits in front of any processor, so you can renegotiate rates without re-tokenizing every customer.
Standalone gateway vs all-in-one
All-in-one solutions like Stripe, Shopify Payments, and Braintree bundle the gateway and processor. They're easy but lock you in — every customer's card token is tied to that one provider. Standalone gateways like Authorize.Net, NMI, and Cybersource separate the layers, so you can change processors while keeping every tokenized customer intact.
- Authorize.Net — gold standard for US ecommerce, deep platform support
- NMI — white-label, used by thousands of ISOs and ISVs
- Stripe — best-in-class developer experience, all-in-one
- Braintree — strong wallets and PayPal integration, all-in-one
- Cybersource — enterprise + B2B with full Level 3
- Adyen — global enterprise, single-platform across regions
Tokenization, vaulting, and customer profiles
A gateway's vault stores tokenized cards on file — critical for subscriptions, one-click checkout, and saved-card upsells. Network tokens (Visa Token Service, Mastercard MDES) automatically update when a customer's card is reissued, recovering 5–15% of subscription revenue that would otherwise fail.
Fraud, 3DS2, and decision rules
Modern gateways include rule-based fraud screening (AVS, CVV, velocity, BIN) plus optional ML scoring (Kount, Signifyd, Sift, Stripe Radar). For ecommerce stores doing $100k+/month, layering fraud tools is non-negotiable — one fraud ring can produce more chargebacks in a week than you'll see in a year.

Frequently Asked Questions
Do I need a separate gateway and processor?+
Not always. All-in-one solutions (Stripe, Braintree, Shopify Payments) work fine for many stores. But if you ever want to renegotiate rates without re-tokenizing customers, a standalone gateway like Authorize.Net or NMI gives you that flexibility.
Can a single gateway connect to multiple processors?+
Yes — NMI, Cybersource, and Spreedly are designed for this. Smart routing lets you send transactions to different processors based on card type, amount, or even cost.
What's the cost of a standalone gateway?+
Typically $10–$25/month plus a few cents per transaction, on top of your processor's rate. Net-net it's almost always cheaper than the equivalent all-in-one once you factor in scale discounts.
