Is there a rental software that integrates w SS shopping cart?

Hello,

I'm building a site that will both sell events/tours as well as rent hardgoods. I'd like everything processed through one shopping cart, ideally the SS one, so customers don't have to have one cart for their event and another for their rental.

The native functionality on SS and the hotel rental options like lodgify are insufficient for this sort of inventory. I've looked into booqable.com which can be embedded on SS and seems great for rentals with a sophisticated Inventory management System and other features. Unfortunately it has its own cart that can't talk to SS and, although they do support ancillary sales of products though their, the way they do it is really not appropriate for what will be my primary business. It's basically just for rentals. 

Are there other good embeddable options? Ideally something w a good infrastructure that just adds the final reservation to the SS cart once inventory and dates etc have been selected. If not, is there an option that offers an API or whatever so that I could hire a developer to integrate it on my SS site?

Thanks for any insight

Squarespace wasn’t designed for this. It simply isn’t possible because you cannot integrate anything with the Squarespace checkout.
