The term “principal book of accounts” refers to the set of ledgers that an entity prepares to group the similar transactions recorded as journal entries under an account.
So to put it simply, the principal book of accounts mean ledgers.
Ledgers are prepared by posting the debits and credits of a journal entry to the respective accounts.

A ledger groups the transactions concerning the same account. For example, Mr B is a debtor of X Ltd. Hence all the transactions entered into with Mr. will be grouped into the ledger Mr B A/c in the books of X Ltd.
Ledgers are of utmost importance because all the information to any account can be known by its ledger.
Preparation of ledger is very important because all the information to any account can be known by its ledger. Ledgers also display the balance of each and every account which may be debit or credit. This helps in the preparation of the trial balance and subsequently the financial statements of an entity.
Hence, it is the most important book of accounts and calling it the ‘books of final entry’ is also justified.

As per AS-10 ( Revised ): Property, Plant and Equipment, depreciation on an asset should begin when the asset is in the location and condition necessary for it to be capable of operating in the manner as intended by the management.
This means a firm should start charging depreciation when the asset is ready to be used as per the management’s desire.
Let’s take an example to understand this clearly:
A business bought a drinking water cooler for its office use on 1st April 2021. Now, this water cooler needs to be installed and wiped with Isopropyl Alcohol before it can be put to use.
The business completed all the required procedures by 1st May 2021, but it opened the machine for office use from 1st August 2021.
So the question arises, from when to start charging depreciation?
The answer is 1st May 2021– The date when the machine was ready to use.
It doesn’t matter whether the company started the use of an asset or not. Once an asset is in
the depreciation should begin.
