This depends on how your current website was built. We offer our Magento / Adobe Commerce version of Sales Igniter Rental System as well as the WordPress / WooCommerce version. If you already have a WordPress website then we suggest you try our WooCommerce Bookings version.
For Magento 2 / Adobe Commerce the recommended way is to add a link on your website that says something like “online bookings” and it links to the Sales Igniter rental booking website. It is also possible to iframe the Sales Igniter rental booking site to your existing site, but this is a bit more difficult and requires the help of a web developer.
