FooEvents POS is a standalone plugin which means that you don’t need to install any other FooEvents plugin extensions in order to use the standard features of the FooEvents POS app. However, in order to use any of the FooEvents integration features including selling and printing tickets, making bookings and selecting seats, you will need to purchase, install and activate the respective FooEvents plugins that perform this functionality, namely, FooEvents for WooCommerce (core), FooEvents Multi-day, FooEvents Bookings and FooEvents Seating.
All these plugins can be purchased separately or as part of a discounted FooEvents Point of Sale Bundle.
