Explanation

The term “set off” in control accounts is also called a contra entry. This occurs when a business has both bought from and sold to the same company, creating balances in both the purchase ledger and sales ledger for that company.

Instead of the company paying us and us paying them separately, a set-off (contra entry) cancels out the matching amounts. For example, if we owe a supplier ₦5,000 but they owe us ₦3,000, we can set off ₦3,000, leaving only ₦2,000 to pay.

In the books, this appears as a debit in the Purchase Ledger Control Account and a credit in the Sales Ledger Control Account for the same amount. It’s called “contra” because the entry goes in opposite directions in related accounts.

Bad debt is writing off amounts that cannot be collected. Brought forward refers to balances carried from a previous period. Direct transfer is not a standard accounting term for this concept.
