There are two ways that the delivery companies load cash. One is to load the money into the cassettes when they arrive on site or some companies may ask you to purchase an additional set of cassettes that are loaded at the vault and they simply swap them out with the existing ones. This is really a request or requirement that a particular service provider may have. Yes, the second option makes the actual delivery quicker. Usually you will just have a particular day of the week that the delivery takes place. For security reasons a lot of the delivery companies won’t give you an exact time but just a window of delivery. You may be able to set up a specific time with your service company but that would really have to be determined by that company and branch.
