Control Accounts (Sales and Purchases Ledger Control Accounts)

### Topic 1: Control Accounts (BK-F3-01)
**Allocated Periods: 20**

#### 1. Concept and Purpose of Control Accounts
- **Definition**: A Control Account is a summary account kept in the General Ledger that checks and replicates the collective total of balances in a subsidiary ledger (Sales Ledger or Purchases Ledger).
- **Core Functions**:
1. *Checks Arithmetical Accuracy*: Proves the mathematical agreement of individual debtor/creditor ledger accounts.
2. *Fraud Prevention & Error Localization*: Separates clerical duties; if a trial balance fails to agree, control accounts instantly reveal which ledger contains the error.
3. *Speed in Financial Reporting*: Provides the total trade receivables and total trade payables figures immediately without waiting to total hundreds of individual personal accounts.
4. *Deducing Missing Figures*: Vital in single entry / incomplete records to determine credit sales or credit purchases.

#### 2. Sources of Information for Control Accounts
Entries in Control Accounts are posted from the **Totals of Books of Prime Entry**, NEVER from individual customer accounts:

#### 5. Contra Settlements (Inter-Ledger Set-Offs)
- When a customer is simultaneously a supplier (e.g., firm sells maize to a trader and buys fertilizer from the same trader).
- Instead of exchanging full cash, their mutual debts are offset against each other to the extent of the smaller balance.
- **Accounting Entry**:
* **Debit**: Purchases Ledger Control Account (reduces what we owe them).
* **Credit**: Sales Ledger Control Account (reduces what they owe us).
