A full-service brokerage firm is a brokerage firm that provides a range of financial services in addition to allowing you to buy and sell securities. These firms can provide customers with financial planning services as well as consulting services. They can also provide trust services and wealth management services. Of course, the level of service you receive is reflected in the commissions the brokerage firm will charge on your orders. This is the most expensive type of brokerage firm. Also with this type of brokerage firm, you will be able to place your buy and sell orders over the internet or over the phone. However, if it's over the phone, the brokerage firm may charge an extra service fee for the additional assistance. Some firms also offer access via smartphones.
