Fortunately, if you've arrived here, you're asking the right questions—or at least one of them—specifically, "What is a general ledger?"
Understanding what a general ledger is and how it works (along with a few closely related and relatively straightforward concepts) will provide you a solid base of knowledge with which you'll be able to gain a better understanding of bookkeeping and accounting in general, and more importantly, what it all means for your business.
When it comes to bookkeeping for your business, the most essential record you'll use to understand its overall financial health is the general ledger, also known as a principal book of accounting, and sometimes referred to as a general journal or simply a GL. Luckily, the general ledger definition is straightforward: It is a financial master document showing a comprehensive record of all business transactions and financial data needed to generate income statements, balance sheets, and financial reports, allowing founders and other stakeholders to quickly get a big-picture look at your business's finances.
The general ledger for most businesses includes five subsidiary ledgers. Though some businesses may have more sub-ledgers, all individual transactions the business conducts is entered into the ledger under at least one of these categories. Here we've listed the five types of general ledger accounts, along with a few examples of accounts classified under each type:
Each of the accounts in the general ledger has its own sub-ledger accounts, exclusively dedicated to invoices and financial transactions that affect that account, where you can view transactions in greater detail. (If you’re getting hung up on the question, “What is a ledger?” it’s just a book where you will record transactions of a given account/accounts.)
To understand how a general ledger works, you'll need to understand a few related concepts: journals, the basic accounting equation, and double-entry bookkeeping.
Before being entered into a ledger, all transactions are first recorded in a journal, which is sometimes referred to as a “book of first entry” or “book of original entry” because it’s the first place a business records transactions. A journal entry consists of a description of the transaction, the date of the transaction, the accounts it affected (as dictated by the chart of accounts), the amount(s), and for most businesses will be entered in the double-entry bookkeeping method (more on that in a moment).
Generally, a business enters transactions into a journal as they occur so that all information is as accurate as possible, rather than having to reconstruct or guess details at a later date. Though journal entries have traditionally been made manually, some forward-thinking accounting firms are now using artificial intelligence (AI) and machine learning (ML) to automate the task.
In order to create a general ledger, a business must use the double-entry method of bookkeeping. In this method, every transaction generates at least two entries—including at least one debit and one credit—which respectively describe whether money is moving to or from an account.
Each transaction in the double-entry accounting method impacts at least two different accounts, and the amount of debits must equal the amount of credits. For example: If a hardware store sells a hammer, the entry for that purchase will show an increase in both the cash and revenue accounts, along with a decrease in the inventory account. In other words, double-entry bookkeeping tracks both where money is coming from and where it’s going. If a business doesn’t record transactions in a journal according to the double-entry method, they won’t contain the information necessary to create a general ledger.
The foundation of the double-entry accounting system is a simple formula:
Assets = Liabilities + Equity
In the equation, assets are resources that the business owns, like cash, equipment, buildings, and even intellectual property like patents or copyrights. Liabilities are obligations the business owes another entity, like accounts payable owed to a supplier or a mortgage owed to a bank. Equity is the amount that would be due to the business’s owners after all debts and liabilities are paid and can include contributions the owners have made to the business, plus profits or minus losses as calculated by deducting expenses from revenue.
Each transaction entered to both the journal (and later, the general ledger) is organized according to this equation, with debits on the left and credits on the right. For accurate reconciliation, the total debit balances must equal the total credit balances.
As we mentioned above, businesses usually enter transactions in the journal as they occur then transferred to the general ledger at the end of a financial period. However, like creating journal entries from transactions, some accounting firms have begun to automate the process of transferring journal entries to the general ledger.
Now that you have an understanding of where the data contained in a general ledger comes from and the principles that underlie how to record and organize that data, it’s time to take a look at what you’re able to do with your general ledger.
Once you’ve compiled all the transaction data from your journals and organized it into ledgers according to your chart of accounts, you’ll be able to:
