Q.What is meant by the Single Entry System of Accounting? State any four of its features.

The Single Entry System is an informal, incomplete method of recording transactions in which only personal accounts and a cash book are generally maintained, with real and nominal accounts largely missing.

Examiners accept any four correctly stated features from the standard list.

The Single Entry System, more accurately called Accounts from Incomplete Records, is the informal way many small traders and partnership firms record their business transactions, without following the strict debit-and-credit rule of double entry bookkeeping for every account. In practice, such a trader usually keeps only a cash book and the personal accounts of debtors and creditors with reasonable regularity, while real accounts (stock, furniture, machinery) and nominal accounts (rent, salaries, commission) are either not maintained at all, or kept only partially and informally.

Its main features are:

1. It is unscientific and unsystematic — there is no single, uniform rule the trader consistently applies to every transaction, unlike the strict, universal debit-credit rule of double entry.
2. Only personal accounts (debtors and creditors) and a cash book are generally maintained with reasonable accuracy; real and nominal accounts are largely missing or incomplete.
3. The dual aspect of a transaction is not consistently captured — many entries record only one side of a transaction, without a corresponding entry on the other account.
4. It is suitable only for sole proprietorships and small partnership firms; a joint stock company cannot legally use this system, since company law requires proper double-entry books.
5. The degree of incompleteness varies genuinely from one trader to another, ranging from a fairly detailed "quasi" single entry (personal accounts, cash book, and some subsidiary registers) down to almost no records at all.

Because a full ledger is missing, no Trial Balance can be extracted directly from the books, which is exactly why special techniques — the Statement of Affairs Method and the Conversion Method — are needed to work out the trader's profit and financial position.

Students sometimes describe the Single Entry System as recording "only one side" of every single transaction with no exceptions — in reality it is a genuine mixture, since personal accounts and cash are usually recorded with both sides (debit and credit), and it is real and nominal accounts that are typically missing, not literally every transaction being halved.
