Jellyfish conveniently separates out inventory into "categories". Supplier accounts are required to select a category for every item uploaded to Jellyfish. For retail accounts, categories come into play when placing orders.
When an admin of the retail account adds a new staff member, the option is there to add categories to the user.
All categories selected on the employees' profile will allow that particular staff member to easily view any items listed under those categories when placing a new order.
