1. Limitations of the General Journal
In a high-volume business, recording every single transaction in a single General Journal creates a bottleneck. It requires writing out repeating account names and narrations thousands of times a day, which slows down operations.
2. The Architecture of Special Journals
To work more efficiently, companies use Special Journals to group high-volume, repetitive transactions. This allows businesses to summarize columns of data and post them to the ledger as a single monthly total, rather than line-by-line.

3. The Remaining Role of the General Journal
When special journals are used, the General Journal is reserved only for unusual or non-recurring transactions, including:
  • Opening entries when starting a business.
  • Period-end adjusting entries (e.g., depreciation, accruals).
  • Closing entries at the end of the fiscal year.
  • Correcting entries to fix accounting mistakes.
