Thanks for reaching out to the Community!
There are some third-party ecommerce integrations with us that would allow you to link to a checkout page for orders. Or, if you have an actual physical order form, you can link to that document for them to download. Also, you can link to your own website or another landing page to process an order form.
If you have any further questions please feel free to reach out to us here. We are always happy to assist you in any way we can!
