Canonical store hours
Publish opening hours, holidays, and exceptions once — cart, checkout, and storefront stay in sync.
WooCommerce plugin
Shift.Gellum
Hours, slots, and staff for WooCommerce.
Calendars that live outside the store drift. Shift.Gellum keeps hours, pickup slots, delivery windows, and staff rosters on the same WooCommerce catalog that takes the order. Capacity is enforced at checkout, exceptions are dated, and operations can see who is on the floor before the ticket prints.
Built for
Local retail, delivery merchants, service-backed stores
In the product
Slot capacity
Cap pickup and delivery windows by volume or staff so the calendar cannot oversell the kitchen or warehouse.
Staff rostering
Assign people to shifts and map those shifts to the windows customers are allowed to book.
Checkout that respects time
Hide or block fulfillment options that the current roster cannot cover.
