A pile of documents becomes manageable when you stop treating it as one task. Do three passes: classify, record, then post.
This page is for the student who meets a long transaction list and has to produce ledgers and a trial balance. The background is in choosing the appropriate source document.
What are the three passes?
Pass 1: classify. Read each document and write one label beside it: sales invoice, purchase invoice, credit note, receipt, cheque stub, or note. Record nothing yet.
Pass 2: record. Enter each labelled document in its book of prime entry. Choosing the correct journal explains which book suits which document.
Pass 3: post. Move the totals to the ledgers, then balance each account.
Worked batch
This is an original batch for a fictional stationery shop. Five documents arrive:
| Document | Amount | Label | Book |
|---|---|---|---|
| Invoice to a customer | RM1 200 | Sales invoice | Sales journal |
| Invoice from a supplier | RM2 000 | Purchase invoice | Purchases journal |
| Credit note to the customer | RM150 | Sales return | Sales returns journal |
| Cheque received from the customer | RM1 050 | Receipt | Cash book |
| Cheque paid to the supplier | RM2 000 | Payment | Cash book |
The customer was invoiced RM1 200, returned goods worth RM150, and paid the balance of RM1 050. The receivable is now nil: 1 200 − 150 − 1 050 = 0. The supplier was invoiced RM2 000 and paid in full, so payables are also nil.
That check at the end is useful in itself. If a customer account does not reach the expected balance, a document is missing or an amount was copied wrongly.
Where students lose marks
Marks go when the return is recorded before the sale, or when a document is forgotten because the list is long. The tick list solves the second. Sorting first solves the first, because the classified list shows the order.
Also watch for documents that look similar. An invoice starts a credit transaction, while a receipt records money arriving. Mix them up and a credit sale becomes a cash sale.
A quick practice plan
Take a long question from your school exercises, or write five documents of your own. Do only the classify pass first, then compare your labels with the answer key if there is one.
Then do the record pass and check the ledgers with the debit-credit transaction trainer. See posting journal entries to ledgers for the final step.
When one-to-one tuition may help
If long questions still leave you stuck after trying the passes, a teacher can sit with one of your own exercises and watch where you pause. The trouble may be one document type, not the whole list.
