Chart of accounts

Chart of accounts is one of Demiton's published registers for Australian civil construction. Your general ledger accounts. Demiton keeps it current from the systems a contractor already runs and publishes the record's shape as a versioned JSON Schema, so the same question works whichever system produced the record.

Part of Financials in the register catalog.
