Unit 3 AOS1A Recording financial Data

Double entry Accounting

A system where every transaction affects at least two accounts and the books always stay balanced.

Assets = Liabilities + Equity

Trial Balance

A list of all the accounts in the General Ledger, and their balances, to determine if total debits equal total credits.

Its purpose is to identify any errors and rectify them

Balancing

Calculating the ending balance of all assets, liabilities and owner's equity ledgers in order to bring these balances forward to the next period.

Errors that can be identified from a trial balance

-two entries recorded on the same side e.g.

-only one entry have been recorded

-different amounts have been recorded on each side

Errors that cannot be identified from a trial balance

-transaction have been omitted altogether

-debit and credit entries have been reversed

-transaction have been recorded in the WRONG ledger account

-an incorrect amount is recorded on both sides

Benefit of Double Entry accounting

- Improves accuracy — every transaction is recorded twice, so errors are easier to detect when totals don't balance.

- Complete financial picture — shows both the source and use of funds, enabling reliable financial statements.

- Better fraud control — built-in checks make manipulation harder and increase accountability.

Internal Control

- Segregation of duties — Different people handle cash, recording, and checking to reduce fraud and errors.

- Rotation of duties — staff periodically change roles to reduce opportunity for fraud.

- Authorisation of transactions — Only approved staff can make purchases, payments, or credit sales.

- Pre-numbered source documents — Invoices, receipts, and memos are numbered to prevent missing or duplicate records.

-Preventative safeguards — procedures e.g. security cameras, alarms designed to stop errors or fraud before they occur.

- Physical safeguards over assets Locks, passwords, and restricted access protect cash, inventory, and equipment.

- Independent checks / reconciliations Bank reconciliations and physical stocktakes verify records against actual balances.

- Staff training — ensures employees understand procedures and follow controls correctly.

- Internal audit / review Regular review of procedures and records to ensure rules are followed.

- Careful hiring practices — background checks and screening reduce risk of dishonest employees.

Importance of corrections

Fixes errors without deleting records — maintains a clear audit trail of what was changed.

Ensures accurate account balances — keeps financial statements reliable and trustworthy.

Maintains integrity of the double-entry system — preserves equality of debits and credits after mistakes are found.
