What is Bookkeeping? The Foundation of Business Financial Management

Written By Maigen Berg

Bookkeeping is the systematic recording of your business's financial transactions. Think of it as your business's financial diary – every dollar that comes in or goes out gets documented, organized, and tracked. It's the foundation that makes all other financial management possible.

What is Bookkeeping?

Bookkeeping is the process of recording, organizing, and maintaining your business's financial transactions on a daily basis. It involves documenting every sale, purchase, payment, and receipt to create a complete financial record of your business activities.

Simple Definition: Bookkeeping tracks every financial transaction your business makes.

Bookkeeping vs. Accounting: What's the Difference?

While often used interchangeably, bookkeeping and accounting serve different purposes:

Bookkeeping:

  • What: Recording transactions

  • When: Daily, ongoing process

  • Who: Bookkeepers, business owners

  • Focus: Data entry and organization

Accounting:

  • What: Analyzing and interpreting financial data

  • When: Periodic analysis and reporting

  • Who: Accountants, CPAs

  • Focus: Financial statements and strategic insights

Think of it this way: Bookkeeping gathers the ingredients, accounting creates the recipe.
