This module covers receivables and payables control accounts: what goes on each side, how a total relates to the individual customer and supplier balances, contra entries between the two ledgers, and how to find the reason a control account and a list of balances disagree. Check the current Cambridge IGCSE Accounting 0452 syllabus page for the exact content points in your exam year.
What should you already know?
You need double entry and the day books from double-entry foundations, and the idea of a trial balance with its limits from trial balance and error limits. You should also be comfortable with the cash book and discounts from cash books and petty cash. If you can balance a simple ledger account, you are ready.
An orienting example
Cendana Books starts April with customers owing RM 3,000 in total. During the month it makes credit sales of RM 10,000, receives RM 9,200 from customers and accepts returns of RM 400.
Step 1, place the opening balance: customers owe the business, so the receivables control account opens with a debit of RM 3,000.
Step 2, enter the month’s totals: credit sales add to what customers owe, so they go on the debit side. Money received and returns reduce what they owe, so both go on the credit side.
Step 3, balance: 3,000 + 10,000 − 9,200 − 400 = RM 3,400 owed by customers at the end of April.
The control account holds totals for the whole ledger. It cannot tell you what any one customer owes. That difference between a total and an individual balance is the thread that runs through every lesson below.
In what order should you study the lessons?
- Build a receivables control account: start here, because the layout and the sides are the foundation for all the rest.
- Build a payables control account: the mirror image, with credit and debit swapped for purchases and payments.
- Distinguish individual balances from totals: why the control account sits in the general ledger while the customer accounts do not.
- Explain a contra between accounts: what happens when one party is both a customer and a supplier.
- Investigate a difference using a fictional schedule: how to trace why the control balance and the list of balances disagree.
After these, try the control accounts practice set. The double-entry and ledger trainer lets you test where each entry lands, and the percentage-base explorer helps when a discount has to be worked out first.
What are the common traps?
- Cash sales in the control account. Only credit sales pass through receivables. Cash sales never create a customer balance.
- Discount on the wrong side. Discount allowed reduces receivables, so it is a credit. Discount received reduces payables, so it is a debit.
- Reading one customer’s balance from the total. The control account gives the whole ledger, not a single person.
- A contra posted to only one control account. A contra always has a debit in one control account and a credit in the other.
- Fixing both sides for one error. Each error usually changes either the control account or the list of balances, not both.
How should you use the practice set?
Rule the control account on paper with debit and credit sides, work the whole question, then open the worked answer. Compare each line, not only the closing balance, because a balance can match by luck while an item sits on the wrong side.
If you keep slipping in the same way, record it in the mistake log and retest queue and retest it a few days later. Students who want someone to watch their choices as they work can consider online one-to-one Accounting tuition, where an assigned teacher can follow each entry as it is made.
