Each store has its own Openfront setup, with its own database, checkout, and payment (Stripe & Paypal) account. The marketplace just connects to the store’s API in real time, fetching products, adding items to the cart, and handing off to checkout. When a customer pays, the funds go directly to the store’s Stripe account.

There’s no central database or shared backend. The marketplace is simply a discovery layer that sits on top of fully independent stores.
