There are multiple ways to customize the quote request page in the normal checkout mode.
First, in the free version, you can modify to the Quote Request page by using the template in “plugins/woo-rfq-for-woocommerce/woocommerce/woo-rfq/rfq-cart.php”.
Copy the folder to the WooCommerce directory in your theme directory and modify it if you wish . You can control the layout and the page template for this page in your WordPress admin area. Typically the Quote Request page looks better with a full-width template without any side-bars.
Using the Plus version, you can customize the quote request page for visitors by navigating to WooCommerce->Settings->RFQ-Toolkit “Quote Request Page” tab. You can make hide or make the field required. Name and email can not be removed and will still be required fields. This feature is available in the Plus version.
Finally, using the Plus version, you can include a Ninja Form in the quote request page to include additional fields of your own choosing. You can create a Ninja form and then select that form in the settings. The form will show in the quote request page. Data captured by the form will show in the order and the email sent to admin.
