What this dot point is asking
SEAB wants you to prepare a petty cash book run on the imprest system, using analysis columns, and to post the column totals. The central insight is that the imprest system keeps small-cash spending under tight control: the cashier starts with a fixed float, spends from it, and is reimbursed at period end by exactly the amount spent, so the float returns to its original size.
The answer
Why a petty cash book
Many payments are small and frequent (stationery, postage, travel). Routing them all through the main cash book would clutter it. A separate petty cash book handles these small payments, kept by a petty cashier under the control of the main cashier.
The imprest system
The imprest system works on a fixed float (the imprest amount):
- The cashier begins the period with the float, say \300$.
- Small payments are made and recorded, each backed by a petty cash voucher.
- At period end the cashier is reimbursed with exactly the total spent.
- This restores the float to \300$ for the next period.
At any moment, cash held plus the vouchers for payments should equal the imprest, which makes checking simple.
Analysis columns
The petty cash book has a total column for each payment, then several analysis columns that classify the payment by type (stationery, postage, travel, sundries). Each payment is entered once in the total column and once in the matching analysis column, so the analysis columns add across to the total.
Posting the totals
At period end:
- Each analysis column total is debited to its expense account in the general ledger (Stationery, Postage, Travel).
- The petty cash book itself is the credit side (the payments), so the double entry is completed by posting the totals.
The sum of the analysis-column totals equals the total spent, which equals the reimbursement.
Examples in context
Example 1. A quick cash check. A manager checks the petty cash tin mid-week. The float is \200\ and there are vouchers for \80120 + 80 = \ equals the imprest, nothing is missing. The imprest system makes this spot-check instant.
Example 2. Classifying spending at a glance. Over a month the analysis columns show travel \400\ and cleaning \250$. Posting these totals to their expense accounts tells the owner exactly how the small-cash budget was used, without sifting through dozens of individual vouchers.
Try this
Q1. State what the imprest amount is and how it is restored. [2 marks]
- Cue. The imprest amount is the fixed petty cash float; it is restored by reimbursing exactly the amount spent at period end.
Q2. A float of \150\ spent during the week. State the reimbursement and the closing float after it. [2 marks]
- Cue. Reimbursement = \95\.
Q3. State how the analysis-column totals are posted to the ledger. [2 marks]
- Cue. Each analysis-column total is debited to its expense account (e.g. Stationery, Postage) in the general ledger.

Original8 marksA business uses the imprest system with a float of \300\, postage \25\, stationery \15$. (a) Prepare the petty cash book with analysis columns for stationery, postage and travel, and balance it. (b) State the amount reimbursed at week end and the postings.Show worked answer →
(a)
| Receipts \
| --- | --- | --- | --- | --- | --- | --- |
| 300 | | Balance b/d | | | | |
| | | Stationery | 40 | 40 | | |
| | | Postage | 25 | | 25 | |
| | | Travel | 60 | | | 60 |
| | | Stationery | 15 | 15 | | |
| | | Totals | 140 | 55 | 25 | 60 |
| | | Balance c/d | 160 | | | |
| 300 | | | 300 | | | |
| 160 | | Balance b/d | | | | |
| 140 | | Cash (reimbursement) | | | | |
(b) Total spent = 40 + 25 + 60 + 15 = \140\ is reimbursed to restore the float to \300\, Postage \25\ (each column total) in the general ledger; the credit is the petty cash payments already recorded.
Markers reward the analysis-column totals adding back to \140\, and posting each column total to its expense account.
Original4 marksExplain how the imprest system works and one advantage it gives over keeping a single large cash float.Show worked answer →
Under the imprest system, the petty cashier starts each period with a fixed float (the imprest amount). Small payments are made and recorded during the period. At the end, the cashier is reimbursed with exactly the amount spent, restoring the float to the original imprest for the next period.
One advantage: it gives strong control. Because the float is reimbursed only by the amount spent, the cash held plus the vouchers for payments should always equal the imprest, making it easy to check that no cash is missing and limiting the amount at risk to the small float.
Markers reward describing the fixed float reimbursed by the amount spent, and an advantage such as easier control or a limited amount of cash at risk.
