• A transaction occurs — You make a sale, pay a bill, receive inventory
• It's recorded as a journal entry — Every entry has at least one debit and one credit (double-entry accounting)
• The entry posts to GL accounts — Each side of the entry goes to the appropriate account in the chart of accounts
• Accounts update — Account balances change to reflect the transaction
• Reports generated — Financial statements (P&L, Balance Sheet, Cash Flow) pull directly from GL data
• You categorize bank transactions → the software creates GL entries automatically
• You create invoices → the software debits AR and credits Revenue
• You record bills → the software debits Expense and credits AP
• Troubleshooting — When numbers don't look right, the GL tells you exactly what happened
• Journal entries — Adjustments, accruals, and corrections still require manual GL entries
• Advisory work — You can't advise on finances if you don't understand how the ledger works
• Month-end close — A proper month-end close involves reviewing GL activity
• Pull GL reports — Run a trial balance and detailed GL transaction report
• Match to source documents — Every GL entry should tie to a bank statement, invoice, or receipt
• Identify discrepancies — Unmatched entries, unusual amounts, missing transactions
• Make adjusting entries — Correct errors, record accruals, adjust prepaid expenses
• Verify balance — Total debits must equal total credits. If not, there's an error to find.
• Spot financial trends before they become problems
• Build custom KPI dashboards from GL data
• Create cash flow forecasts based on historical GL patterns
• Provide profitability analysis by department, product, or service line
