Payment gateway

Hello,

I have been using Grand Tour | Travel Agency WordPress by ThemeGoods | ThemeForest theme for my site egtours.com. I have a payment gateway plugin provided by my bank. But when I want to make a payment option, I need to create individual products via woocommerce while I already have products as ‘tours’ is that not possible to use my payment gateway directly from ‘tours’ pages instead of creating additional products via woocommerce?
