2. Helcim — Best for Stores Processing $30K+/Month

Quick answer: Helcim's interchange-plus pricing automatically reduces as your volume grows. At $50K/month you pay interchange + 0.30% + $0.08, meaningfully lower than Stripe's flat 2.9%. No monthly fee, no cancellation fees, and includes a free virtual terminal and invoicing tool.

3. Shopify Payments — Best for Shopify Merchants

Quick answer: Shopify charges 0.5% to 2% extra when you use a third-party processor. Shopify Payments eliminates that surcharge. On the Basic plan you pay 2.9% + $0.30; on the Shopify plan, 2.6% + $0.30. For any Shopify store in a supported country, the math almost always favors native payments.

Tied to your Shopify account — if your store is suspended, so is Payments

Who this is best for: Every Shopify merchant in a supported country. This is the default correct choice.

4. PayPal / Braintree — Best for Brand Trust and BNPL

Quick answer: 400 million active PayPal accounts means millions of shoppers will see a familiar checkout button and convert more readily. PayPal's standard online rate is 3.49% + $0.49; Braintree (its developer platform) offers 2.59% + $0.49 with more customization.

5. Square — Best for Hybrid In-Store and Online Sellers

Quick answer: Square's 2.9% + $0.30 online rate matches Stripe, but its strength is unified inventory and reporting across physical retail and ecommerce. Free POS hardware, built-in loyalty programs, and seamless channel sync make it the top choice for retailers who sell in both environments.

Rate: 2.9% + $0.30 (online); 2.6% + $0.10 (in-person)

Frequently Asked Questions

What is the difference between a payment gateway and a payment processor?
A payment gateway routes encrypted transaction data between your store and the banking network. A payment processor handles authorization, settlement, and fund transfer. Modern solutions like Stripe combine both in one service.

Which payment gateway has the lowest fees for ecommerce?
Helcim offers the lowest effective fees for stores processing $30K+/month via interchange-plus pricing. Stripe is most cost-effective for lower-volume stores with no monthly fee eating into margins.

Can I use two payment gateways on my store?
Yes, and many stores do. A common setup is Stripe as the primary gateway with PayPal as an additional option — typically increasing checkout completion by 10–15%.

Is Stripe safe for ecommerce?
Yes. Stripe is PCI DSS Level 1 compliant, the highest level of payment security certification. Its Radar fraud system uses machine learning across billions of transactions to flag suspicious activity.

How long do payment gateway payouts take?
Standard payout times are 1–3 business days for most gateways. Instant payouts are available from Stripe (1% fee), Square (1.75% fee), and PayPal, allowing same-day access to funds.

What payment gateway works best with WooCommerce?
Stripe is the most popular and actively maintained gateway for WooCommerce via the official Stripe WooCommerce plugin. PayPal is a strong secondary option to display at checkout alongside Stripe.

Do payment gateways charge monthly fees?
Stripe, Helcim, Square, and PayPal have no monthly fees. Authorize.net charges $25/month. Adyen has a minimum monthly processing threshold. Shopify Payments is included in your Shopify plan cost.

What is interchange-plus pricing?
Interchange-plus pricing passes the actual card network cost (interchange) directly to you, then adds a fixed processor markup. It is more transparent and usually cheaper at scale than flat-rate pricing like Stripe's 2.9% model.

Which gateway is best for selling internationally?
Stripe supports 135+ currencies and local payment methods across Europe, Asia, and Latin America, making it the top choice for international ecommerce. Adyen is better for enterprise-scale global operations.

What should I look for when choosing a payment gateway?
Evaluate: transaction fees at your expected volume, platform compatibility with your ecommerce software, payout speed, fraud protection tools, international support if needed, and account stability history.
