Invoices and manual payments
Merchants can use gateway tools for payment requests when they need to collect payment outside of the normal website checkout.

- Phone orders and custom orders
- Wholesale or special requests
Voids and refunds
Eligible transactions can be voided before settlement or refunded after capture through the connected gateway tools.

WordPress is a strong fit when the merchant wants control.
WordPress is flexible. Merchants can build stronger product pages, publish SEO content, use custom plugins, and adjust the checkout experience more than they can on many closed platforms.
For high risk ecommerce, that control matters. A merchant may need to update policies, add checkout disclosures, improve product pages, connect a gateway, and keep the site compliant without rebuilding everything.
