Transaction Categorization
Short answer
Transaction categorization is the process of assigning each business transaction to the correct account — income, expense, asset, or liability — so that reports accurately reflect what the money was for.
Why it matters
Categorization is where accuracy is built or lost. Correct categorization produces trustworthy reports; sloppy categorization produces reports that look complete but mislead. Every report depends on this step.
How it works
Each transaction from a bank feed, receipt, or invoice is reviewed and assigned to an account in the chart of accounts. Over time, recurring transactions can be memorized, but each one still needs review to stay accurate.
A simple example
A $120 charge at an office supply store is categorized to 'Office Supplies,' not left as a generic bank-feed entry or mixed into 'Miscellaneous Expenses.'
A common misunderstanding
Letting software auto-categorize every transaction without review is a common shortcut that quietly introduces errors. Automated suggestions are a starting point, not a finished step.
