Not a rule
Bookkeeping convention — not codified. US GAAP governs recognition, measurement and presentation — not the mechanics a bookkeeper uses to get there. Anyone citing a standard for this word is citing the wrong thing.
Every citation in this system, with the text we read and the date we checked it, is in US GAAP and where these rules come from.

Journal entry, in use
Quoted from the 2 documents that use the word — what it does to an interface, in the spec's own sentence.
Each has a distinct shape, and AdjustingEntryForm offers them as templates rather than a blank journal entry.
Journal entry balancer: paste or key lines, see the debit/credit totals, the out-of-balance, and copy an import-ready CSV.
For founders
The same idea written for a founder: what it costs a startup that ignores it, and what to do in a real month.

- Chart of accounts for startups: a starting templateA starting chart of accounts for a US startup: number ranges, the expense accounts you need, and when to add an account versus a class or tracking tag.
- Can you vibe code your startup’s accounting?AI coding tools build a finance dashboard in an afternoon, but not a closed, reconciled, GAAP-basis ledger. Where the line is, and how to stay inside it.

What it is not called
Each of these is a real word for a different thing. Using it here is what makes a product read as though it was built by someone who has not done the work.

Components that render this
The concept is not documentation-only. These are the components that name it in their specification, grouped and stated exactly as the catalog states them.
Components that render the terms it depends on
Little in the catalog names this concept outright, but its definition is built out of others that are named. These render credit, debit.

Work with this concept
The calculators that compute it and the ledger payloads that carry it. A definition is where a reader starts; these are where they go next.
