There might be some confusion here. There are actually two main types of bookkeeping systems used to record financial transactions:

  1. Single-entry bookkeeping: This is a simpler system that records only one side of a transaction. For example, if you buy office supplies for $50, you would only record a $50 increase in your expenses account.
  2. Double-entry bookkeeping: This is a more complex system that records both sides of a transaction. In the same example, you would debit (increase) your office supplies account by $50 and credit (decrease) your cash account by $50. This method ensures that your books are always balanced and provides a more complete picture of your finances.

It's important to note that while there are different accounting methods (like cash basis vs. accrual basis), these are not considered separate types of bookkeeping systems. They determine when income and expenses are recognized, but the actual recording process still falls under single-entry or double-entry.
