# ViKING POS shop assistant roles

* **Operator:**

  * An operator is associated with a cash drawer and is responsible for the money in the cash drawer.
  * Multiple operators may use the same till during a day, but in that case they'll remove their cash drawer and make a cash statement (either on the till or on a backoffice solution) when they finish working at the till. When another operator begins working at the till, they'll bring their own cash drawer.
  * An operator can only be active on one till at a time, because there's a one-to-one relation between the operator and the money in the cash drawer that the operator uses. That means that an operator can't work on till number 2 if they're already logged in on till number 1.
  * An operator is occasionally also called a *cashier*.

* **Salesperson:**

  * A salesperson is someone who uses a till. You typically use salespersons when multiple shop assistants share one or more tills during a day.
  * Sales are registered on the salesperson who makes the sale on the till, but money in the cash drawer is shared between all salespersons who use the till.
  * A salesperson typically logs in to the till for every sale, and they're typically automatically logged out when the sale has been completed.

> **Info**
>
> It's possible to set up tills to run with a **fixed operator** (that is an operator who's permanently logged in to the till), but cash statements must always be made by an operator, not by a salesperson. Consequently, the only way to make a cash statement is as an operator. See also [ViKING till balance & bookkeeping](/help/concepts/till-balance-book).
