WooCommerce Payment Processing
Quick answer: WooCommerce is the best eCommerce platform for high-risk merchants because it charges zero additional gateway fees — unlike Shopify which adds 0.5-2% on top of your processor's rate. The best WooCommerce gateways for high-risk businesses are PayTrace, NMI, and Authorize.net through a high-risk merchant account. For low-risk businesses, WooCommerce Payments (powered by Stripe) works but has the same limitations as Stripe.
WooCommerce powers over 6.5 million online stores and is the most flexible eCommerce platform for payment processing. Unlike Shopify's closed ecosystem, WooCommerce lets you connect any payment gateway without additional platform fees.
WooCommerce vs Shopify for Payment Processing
| Feature | WooCommerce | Shopify |
|---|---|---|
| Additional gateway fees | 0% | 0.5-2.0% |
| Gateway options | Any (via plugins) | Limited third-party list |
| High-risk support | Full (any gateway) | Third-party only |
| Monthly platform cost | Hosting only ($10-50/mo) | $39-399/mo |
| Technical management | Self-managed | Managed |
For high-risk merchants, the zero-gateway-fee advantage is significant. A store processing $50K/month saves $250-1,000/month on Shopify's extra gateway fee alone.

WooCommerce Payments (Stripe) Limitations
WooCommerce Payments is powered by Stripe and has the same restrictions:
- Prohibits high-risk industries (vape, firearms, CBD, adult, gambling, etc.)
- Can freeze funds or terminate with limited notice
- Flat-rate pricing (not interchange-plus)
- No dedicated account manager
If you sell in any high-risk category, do not use WooCommerce Payments — use a third-party gateway from a high-risk processor.
