Shopify v. Squarespace v. DripOS

Hi! We’re planning to have our own coffeeshop—we don’t know anything about this space but we’d like to make this work and serve our community.

What would be the best option to build a website that will eventually be used as a site to for our customers to place and pick orders, and will be integrated with some merchandiser? What are the pros and cons of using Shopify or Square or DripOs in the food/beverage industry?

We’d also like to build an app specifically for placing orders—any tips or things to keep in mind when building one?
