Bookkeeping is the recording of financial transactions, and is part of the process of accounting in business.
Transactions include purchases, sales, receipts, and payments by an individual person or an organization/corporation. There are several standard methods of bookkeeping, such as the single-entry bookkeeping system and the double-entry bookkeeping system, but, while they may be thought of as "real" bookkeeping, any process that involves the recording of financial transactions is a bookkeeping process.
Bookkeeping is usually performed by a bookkeeper. A bookkeeper (or book-keeper) is a person who records the day-to-day financial transactions of a business. They are usually responsible for writing the daybooks, which contain records of purchases, sales, receipts, and payments. The bookkeeper is responsible for ensuring that all transactions whether it is cash transaction or credit transaction are recorded in the correct daybook, supplier's ledger, customer ledger, and general ledger; an accountant can then create reports from the information concerning the financial transactions recorded by the bookkeeper.
Bookkeeping refers mainly to the record-keeping aspects of accounting. Bookkeeping involves preparing source documents for all transactions, operations, and other events of the business.
The bookkeeper brings the books to the trial balance stage: an accountant may prepare the income statement and balance sheet using the trial balance and ledgers prepared by the bookkeeper.
The origin of book-keeping is lost in obscurity, but recent researches would appear to show that some method of keeping accounts has existed from the remotest times. Babylonian records have been found dating back as far as 2600 B.C., written with a stylus on small slabs of clay.
The term "waste book" was used in colonial America referring to bookkeeping. The purpose was to document daily transactions including receipts and expenditures. This was recorded in chronological order, and the purpose was for temporary use only. The daily transactions would then be recorded in a daybook or account ledger in order to balance the accounts. The name "waste book" comes from the fact that once the waste book's data were transferred to the actual journal, the waste book could be discarded.
The bookkeeping process primarily records the financial effects
of transactions. The difference between a manual and any electronic accounting system results from the former's latency (engineering) between the recording of a financial transaction and its posting in the relevant account. This delay—absent in electronic accounting systems due to nearly instantaneous posting into relevant accounts—is a basic characteristic of manual systems, thus giving rise to primary books of accounts such as Cash Book, Bank Book, Purchase Book, and Sales Book for recording the immediate effect of a financial transaction.
In the normal course of business, a document is produced each time a transaction occurs. Sales and purchases usually have or . Deposit slips are produced when lodgements (deposits) are made to a bank account. Checks (spelled "cheques" in the UK and several other countries) are written to pay money out of the account. Bookkeeping first involves recording the details of all of these source documents into multi-column journals (also known as books of first entry or daybooks). For example, all credit sales are recorded in the sales journal; all cash payments are recorded in the cash payments journal. Each column in a journal normally corresponds to an account. In the single entry system, each transaction is recorded only once. Most individuals who balance their check-book each month are using such a system, and most personal-finance software follows this approach.
After a certain period, typically a month, each column in each Journal entry is totalled to give a summary for that period. Using the rules of double-entry, these journal summaries are then transferred to their respective accounts in the ledger, or account book. For example, the entries in the Sales Journal are taken and a debit entry is made in each customer's account (showing that the customer now owes us money), and a credit entry might be made in the account for "Sale of class 2 widgets" (showing that this activity has generated revenue for us). This process of transferring summaries or individual transactions to the ledger is called posting. Once the posting process is complete, accounts kept using the "T" format undergo balancing, which is simply a process to arrive at the balance of the account.
As a partial check that the posting process was done correctly, a working document called an unadjusted trial balance is created. In its simplest form, this is a three-column list. Column One contains the names of those accounts in the ledger which have a non-zero balance. If an account has a debit balance, the balance amount is copied into Column Two (the debit column); if an account has a credit balance, the amount is copied into Column Three (the credit column). The debit column is then totalled, and then the credit column is totalled. The two totals must agree—which is not by chance—because under the double-entry rules, whenever there is a posting, the debits of the posting equal the credits of the posting. If the two totals do not agree, an error has been made, either in the journals or during the posting process. The error must be located and rectified, and the totals of the debit column and the credit column recalculated to check for agreement before any further processing can take place.
Once the accounts balance, the accountant makes a number of adjustments and changes the balance amounts of some of the accounts. These adjustments must still obey the double-entry rule: for example, the inventory account and asset account might be changed to bring them into line with the actual numbers counted during a stocktake. At the same time, the expense account associated with usage of inventory is adjusted by an equal and opposite amount. Other adjustments such as posting depreciation and prepayments are also done at this time. This results in a listing called the adjusted trial balance. It is the accounts in this list, and their corresponding debit or credit balances, that are used to prepare the financial statements.
Finally financial statements are drawn from the trial balance, which may include:
the income statement, also known as the statement of financial results, profit and loss account, or P&L
the balance sheet, also known as the statement of financial position
the cash flow statement
the Statement of changes in equity, also known as the statement of total recognised gains and losses
Two common bookkeeping systems used by businesses and other organizations are the single-entry bookkeeping system and the double-entry bookkeeping system. Single-entry bookkeeping uses only income and expense accounts, recorded primarily in a revenue and expense journal. Single-entry bookkeeping is adequate for many small businesses. In the double-entry accounting system, at least two accounting entries are required to record each financial transaction. These entries may occur in asset, liability, equity, expense, or revenue accounts.
The primary bookkeeping record in single-entry bookkeeping is the cash book
, which is similar to a checking account (UK: cheque account, current account) register, but allocates the income and expenses to various income and expense accounts. Separate account records are maintained for petty cash, accounts payable and receivable, and other relevant transactions such as inventory
and travel expenses. These days, single-entry bookkeeping can be done with DIY
bookkeeping software to speed up manual calculations.
A double-entry bookkeeping system
is a set of rules for recording financial information in a financial accounting system in which every transaction or event changes at least two different nominal ledger
is a descriptive and chronological (diary-like) record of day-to-day financial transactions also called a book of original entry
. The daybook's details must be entered formally into journals to enable posting to ledgers. Daybooks include:
Sales daybook, for recording all the sales invoices.
Sales credits daybook, for recording all the sales credit notes.
Purchases daybook, for recording all the purchase invoices.
Purchases Debits daybook, for recording all the purchase Debit notes.
Cash daybook, usually known as the cash book, for recording all money received as well as money paid out. It may be split into two daybooks: receipts daybook for money received in, and payments daybook for money paid out.
General Journal daybook, for recording journals.
Petty cash book
A petty cash
book is a record of small-value purchases before they are later transferred to the ledger and final accounts; it is maintained by a petty or junior cashier. This type of cash book usually uses the imprest system
: a certain amount of money is provided to the petty cashier by the senior cashier. This money is to cater for minor expenditures (hospitality, minor stationery, casual postage, and so on) and is reimbursed periodically on satisfactory explanation of how it was spent.
are recorded in the general journal daybook. A journal is a formal and chronological record of financial transactions before their values are accounted for in the general ledger as debits and credits. A company can maintain one journal for all transactions, or keep several journals based on similar activity (e.g., sales, cash receipts, revenue, etc.), making transactions easier to summarize and reference later. For every debit journal entry recorded, there must be an equivalent credit journal entry to maintain a balanced accounting equation.
is a record of accounts.The ledger is a permanent summary of all amounts entered in supporting Journals which list individual transactions by date. These accounts are recorded separately, showing their beginning/ending balance. A journal lists financial transactions in chronological order, without showing their balance but showing how much is going to be charged in each account. A ledger takes each financial transaction from the journal and records it into the corresponding account for every transaction listed. The ledger also sums up the total of every account, which is transferred into the balance sheet
and the income statement
. There are three different kinds of ledgers that deal with book-keeping:
Sales ledger, which deals mostly with the accounts receivable account. This ledger consists of the records of the financial transactions made by customers to the business.
Purchase ledger is the record of the purchasing transactions a company does; it goes hand in hand with the Accounts Payable account.

Chart of accounts
A chart of accounts is a list of the accounts codes that can be identified with numeric, alphabetical, or alphanumeric codes allowing the account to be located in the general ledger. The equity section of the chart of accounts is based on the fact that the legal structure of the entity is of a particular legal type. Possibilities include sole trader
, and company

Computerized bookkeeping removes many of the paper "books" that are used to record the financial transactions of an entity—instead, relational databases take their place, but they still typically enforce the double-entry bookkeeping system and methodology. CPAs design the internal controls for the computerized bookkeeping system, which serve to minimize errors in documenting the big number of activities that the entity engages in over the period.
