The Accounting Journal and Ledger plugin provides a lightweight way to practice and document double-entry bookkeeping inside your notes. It supports three custom block formats: a modern journal style, a traditional Spanish-style journal, and a T-account ledger layout. Entries are written in Markdown blocks with simple tags, then converted into clear HTML previews for better readability and presentations. You can register transactions with dates, concepts, debits, and credits, split them into phases, and view balances in a ledger format. The plugin also accepts a custom chart of accounts via CSV, so account names can be displayed consistently in both journal and ledger exports.
