The video demonstrates how to use journal entries in BrizoSystem. It begins by navigating to Journal Entries under settings. Users can create entries for scenarios like Actual, Forecast, or Budget. By clicking “Add a new journal entry,” they input a Journal ID, description, date, debit and credit accounts, and the amount to apply. Once confirmed, the journal entry is immediately reflected in the system. Journal entries can be applied at both the individual organization level and the consolidated level.
