I am about to launch SaaS platform for corporates. Can I use WIX only for the Homepage, but the rest of the site will be the SaaS?

I want to use WIX for the Homepage and Customer Facing area, and keep the SaaS platform as is. How/if can I combine these two worlds.
Any good advice is well appreciated.
Thank you in advance.

You need to buy domain in some other platform. Premium plan in wix.
Redirect www.yourdomain.com to wix home page.
In wix menu redirect other pages to SaaS.

Thank you . But this will turn it into 2 separate sites with 2 completely different domains. I wonder if there is another way.
