Do I need woocommerce in my case?

Question

WordPress

I'm making a website that has the same theme as this one
. Only, unlike it, I just have a one-pager, where you can also select a menu and order it.
Do I need a woocommerce landing page, in theory, I don’t need pages that the plugin creates like /cart, /checkout and others. Or I need a plugin, I just don't understand it.
That is, in my landing page, you simply select the menu, click order and leave the number.

Answer 1

not needed.
make a custom post for the items.
when ordering, put js-th information about the ordered product in the submission form.
