In the way I work as a sales assistant, I was in charge of assisting in sales. I also help in taking stock of what is available. As a transaction coordinator, I help in managing transactions like cash. I keep track of money that is entering and also going out. I take record of all things that are being done. Basically, the main factor I had was having a customer relationship.
