Basic bookkeeping in QuickBooks Online

QuickBooks Online gives users powerful tools to track all of their financial activities. Here’s an overview of a few fundamental features small businesses use everyday in QuickBooks:

QuickBooks is based on double-entry bookkeeping. This is a very common accounting system in the US and many other countries.

With double-entry bookkeeping, all records involve two (or more) related accounts. Accounts serve as reference points for transactions. Any time a user creates or updates a record in QuickBooks, it increases the value of one account and decreases the same value of a corresponding account. For example:

Tip: These increases and decreases are often called “debits” and “credits.” Debits and credits can either increase or decrease the value of an account. What gets debited or credited, however, depends on the types of transactions and accounts involved. Learn more about debits and credits.
