# Account price list
Financial institutions need to set up various fees such as fees for transactions on customer accounts, recurring fees for account maintenance, or one-time fees for contract changes or extra services. With the Tuum BackOffice, you can define account price lists and corresponding prices for automatic calculation and application of these fees.
## Definitions
* **Price -** A set of conditions to calculate the fee amount.
* **Special price -** A price specific to an account or a customer. The special price overwrites the price in the account price list.
* **Price list -** A set of prices. A price list is assigned to a customer group that determines the accounts that can use this price list.
* **Generic price list -** A list of prices which work as a backup reference determining the fee for a particular transaction in case the price is not present in account price lists. Generic price lists cannot be assigned to an account.
* **Fee -** The amount of money calculated and charged from an account as account fee transactions (debited immediately) or as account fee bookings (accumulated and debited later) per the respective price.
The following diagram shows how a price is selected for fee calculation:
