Hi Whitney, I would recommend using Webflow to design the marketing website, and use Laravel for the customer portal. You can also use Webflow for the design of the customer portal area, but as far as the marketing goes, I would keep your marketing site separate from your customer app, as you won't want marketing people to have access to customer info easily, and you will want to separate concerns to keep things easy to manage.

Your desire for employees to easily update site content is easy to do with Webflow, and will be the best cms for the marketing side.

Reason why I recommend Laravel for the customer app, is that it is secure, highly scalable, well designed, and you will easily find people to help with future development of the site.

If you would like help with any of this, I would be happy to help. I have a small web development and design company.
