what is a transaction account and why is it a demand deposit
Transaction account A transaction account, checking account, current account or demand deposit account is a deposit account held at a bank or other financial institution. It is available to the account owner "on demand" and is available for frequent and immediate access by the account owner or to others as the account owner may direct. Access may be in a variety of ways, such as cash withdrawals, use of cheques (checks) and debit by electronic transfer. In economic terms, the funds held in a transaction account are regarded as liquid funds and in accounting terms they are considered as cash.
Imprest system The imprest system is a form of financial accounting system. The most common imprest system is the petty cash system. The base characteristic of an imprest system is that a fixed amount is reserved, which after a certain period of time or when circumstances require, because money was spent, it will be replenished. This replenishment will come from another account source, e.g., petty cash will be replenished by cashing a cheque drawn on a bank account.
