PaysonCheckout for WooCommerce Plugin

• All payment methods with one contract
• No fixed fees, get started within 24 hours
• The customer never leaves your e-commerce store

In PaysonCheckout Payson has removed all unnecessary steps in the checkout to increase conversions and sales. The payment window is nicely integrated into your e-store where customers can pay with a single click! All purchases are based on the service Invoice via email.
