Petty cash is the small amount of cash a business keeps on hand — usually RM200 to RM1,000 — to pay for tiny, urgent costs that aren't worth a bank transfer. Most Malaysian owners just call it the cash box, the office money, or duit pejabat.
Here's the version that actually matters. Every business has one drawer where money quietly disappears.
RM8 for parking. RM19 for printer paper. RM25 for a courier.
Nobody remembers who took what. There's no receipt for half of it. At year-end your accountant finds a few thousand ringgit that left the bank "for petty cash" and almost nothing to show what it bought.
Petty cash, done properly, is the system that prevents exactly that. It takes about five minutes a week.
This guide is written for the owner, not the accountant. What it is, what to call it in Malay, when to use it and when not to, how much to keep, how it works with QR payments and online banking, and the mistakes that cost real money — plus free templates and a monthly audit checklist you can use today.
01. What is petty cash, in plain terms
It's a fixed amount of cash, kept in one box, that one person is responsible for — and every ringgit that leaves it gets written down with a receipt.
That's the whole idea. Two things make it petty cash rather than money in a drawer:
- It's a fixed amount. You decide it's RM300, and it stays RM300. Accountants call this the float — just a word for "the set amount you start with".
- Every payment is written down. A slip, a receipt stapled to it, done.
Take away either one and you don't have petty cash. You have a drawer.
02. Petty cash in Malay: wang runcit, tunai runcit
You'll hear this in more than one language, so here are the terms side by side.
| English | Malay | What people actually say |
|---|---|---|
| Petty cash | Wang runcit | The standard term in formal and accounting use |
| Petty cash | Tunai runcit | Tunai is "cash", runcit is "small/retail" |
| Petty cash | Wang petty | The everyday mix you'll hear in the shop |
| The float | Wang pendahuluan / float | The fixed amount kept in the box |
| Petty cash voucher | Baucar wang runcit | The slip filled in for each payment |
Maksud petty cash: wang tunai dalam jumlah kecil yang disimpan untuk perbelanjaan harian yang kecil. Your staff will understand all three terms — what matters is that whoever holds the box knows the rules.
03. Should this payment come out of petty cash?
Three questions. If any answer is no, it doesn't belong in the box.
The limit is the part most businesses skip, and it's the one that does the work. Write a number on paper — RM100 and RM200 are the usual choices — and anything above it goes through the bank. That single rule stops the box being used for things it was never meant to cover.
04. When NOT to use petty cash
These should never come out of the box, no matter how convenient it is at the time:
| ❌ Never from petty cash | Why not |
|---|---|
| Salaries or wages | Payroll needs a record trail. Cash wages from a box are untraceable for both of you. |
| Stock or inventory | Goods for resale belong in your purchases and stock records, not buried in expenses. |
| Supplier invoices | An invoice has payment terms and a paper trail. Pay it through the bank so both sides can match it. |
| Rent, utilities, insurance | Fixed, predictable and large. There's never an urgency argument. |
| Equipment or furniture | A printer or a chair is an asset, not a small expense. Different treatment entirely. |
| Personal spending | The fastest way to lose the ability to prove any of your expenses. Never, not even "I'll put it back". |
The "I'll put it back tomorrow" problem. Taking cash out with the intention of replacing it is the single most common way petty cash goes wrong — not because anyone is dishonest, but because the box now contains an amount that matches neither the record nor the receipts, and the person who knows why is the person who's out of the office. If you genuinely need to borrow from the box, write a voucher for it. The habit is what protects you.
05. A real week in a small shop
This is what a normal week actually looks like, starting from a RM300 float:
| Day | What happened | Out (RM) | Cash left (RM) |
|---|---|---|---|
| Monday | Courier — documents to a client | 18.00 | 282.00 |
| Tuesday | Parking, supplier delivery | 7.00 | 275.00 |
| Wednesday | Grab — staff to the bank and back | 22.00 | 253.00 |
| Thursday | Drinks for a customer meeting | 36.00 | 217.00 |
| Friday | Printer ink | 39.00 | 178.00 |
RM122 in five days, and not one payment big enough to argue about. That's the point worth sitting with: petty cash almost never disappears in one dramatic theft. It leaves in amounts too small for anyone to question — eighteen ringgit here, twenty-six there — which is precisely why it goes unnoticed until the year-end accounts don't add up.
Five slips of paper would have made that week fully explainable. That's the entire cost of doing it properly.
06. Is petty cash an asset or an expense?
Both, at different moments — and this is the bit that trips people up.
- The cash sitting in the box is an asset. It's still your money; you just haven't spent it yet. It sits on your balance sheet like the money in your bank account.
- The spending is an expense. The moment RM19 leaves for printer paper, that RM19 becomes an office supplies expense and reduces your profit.
That broken chain is why sloppy petty cash quietly overstates your profit: the money is gone, but your accounts never recorded what it bought.
07. How much should you keep?
There's no legal figure, and anyone quoting a standard is guessing. The working rule: two to four weeks of small spending, and no more.
| Type of business | Typical float | Why |
|---|---|---|
| Service business or small office | RM200 – RM300 | Occasional postage, parking, stationery |
| Retail shop | RM300 – RM500 | More small purchases, more frequent top-ups |
| Café or restaurant | RM500 – RM1,000 | Daily small buys — ice, a forgotten ingredient, a gas top-up |
The float is usually wrong in one direction: too big. A float that's too small announces itself immediately — someone is asking you for a top-up every few days, and it's annoying. A float that's too large never complains. It just sits there, quietly increasing what you can lose and how long it takes to notice. If you're topping up less than once a month, your float is too big; cut it and nothing bad happens.
08. The float, and why it never changes
The method has an intimidating name — the imprest system — and a very simple rule: the box always gets topped back up to the same fixed amount.
The whole control is one line, and it's worth writing inside the box lid:
cash left + receipts held = the float
If those don't match, you know this month — not next year — and you know exactly how much is missing.
09. The voucher: the 10-second habit
A voucher is the slip filled in each time money leaves the box. It turns "RM45 is gone" into "RM45 went to a courier on 12 March, approved by the manager, receipt attached."
This is the small version of the form. For anything paid out of the bank — a supplier invoice, a cheque, a transfer — you want the fuller payment voucher instead, which carries the invoice reference and a separate approval signature.
Only two things on it are easy to get wrong. The description must be specific — "Courier to client, Shah Alam", never "misc", because "misc" is what an unexplainable expense looks like six months later. And the person approving must not be the person taking the cash. That one separation is the difference between a control and a note to yourself.
No receipt, no reimbursement. When a receipt genuinely can't be issued — a parking machine that prints nothing — write why on the voucher and have someone else sign it. Keep that rare. If it's happening weekly, the problem isn't the receipts, it's the process.
10. The petty cash book
The running log of the box: one line per payment, with a balance that updates as you go.
| Date | Voucher | Description | Category | Out (RM) | In (RM) | Balance (RM) |
|---|---|---|---|---|---|---|
| 1 Mar | — | Opening float | — | 300.00 | 300.00 | |
| 4 Mar | 001 | Parking — supplier delivery | Travel | 8.00 | 292.00 | |
| 7 Mar | 002 | Printer paper (2 reams) | Office supplies | 38.00 | 254.00 | |
| 12 Mar | 003 | Courier to client — Shah Alam | Postage | 45.00 | 209.00 | |
| 19 Mar | 004 | Client meeting — refreshments | Entertainment | 64.00 | 145.00 | |
| 26 Mar | 005 | Light bulbs, cleaning supplies | Maintenance | 70.00 | 75.00 | |
| 31 Mar | — | Top-up to restore float | — | 225.00 | 300.00 |
The balance fell to RM75, the vouchers totalled RM225, and the RM225 top-up brought it back to RM300 exactly. The Excel version does this arithmetic for you.
11. Putting it into your accounts
Only two moments touch your books.
Setting up the float — money moves from bank to box. Nothing has been spent, so nothing is an expense yet:
| Account | Debit (RM) | Credit (RM) | In plain terms |
|---|---|---|---|
| Petty Cash | 300.00 | Cash arrives in the box | |
| Bank | 300.00 | Cash leaves the bank |
Topping up at month-end — this is when the spending gets recorded, category by category from your vouchers:
| Account | Debit (RM) | Credit (RM) | In plain terms |
|---|---|---|---|
| Travel | 8.00 | Parking | |
| Office supplies | 38.00 | Printer paper | |
| Postage | 45.00 | Courier | |
| Entertainment | 64.00 | Client refreshments | |
| Maintenance | 70.00 | Bulbs and cleaning | |
| Bank | 225.00 | Cash withdrawn to restore the float |
Notice the Petty Cash account itself is untouched at top-up — under the imprest system it stays at RM300 permanently. That's why the balance sheet figure is always easy to verify: go and count the box.
12. What most businesses get wrong
Petty cash rarely fails dramatically. It fails by drift — and almost always in the same five ways.
| The mistake | What it looks like | The fix |
|---|---|---|
| 1. Everyone has a key | Three people take cash "when needed". Nobody is accountable because everybody is. | One named custodian — one person who holds the box and answers for it. |
| 2. Mixed with the sales till | The day's takings and the petty cash live in the same drawer, so neither can be counted. | Separate box, separate count. Sales money is not spending money. |
| 3. Receipts collected "later" | A month of loose slips in an envelope, half of them faded thermal paper. | Voucher at the moment of payment, receipt stapled on the spot. |
| 4. The owner treats it as their wallet | Cash out for personal things with the intention of repaying. Sometimes it happens. | If it leaves the box, it gets a voucher — the owner included. |
| 5. Counted only when something feels wrong | By the time anyone counts, the trail is months cold. | Count monthly, on a date, whether or not anything feels off. |
A balancing box is not the same as a well-run box. The count can come out perfectly while the habit underneath is rotting — the same payee every week, round numbers with no receipt, amounts creeping up month on month. When you count, look at the pattern of the vouchers, not just the total. The total is the last thing to go wrong, not the first.
13. Petty cash, QR payments and online banking
A fair question in 2026: if you can DuitNow someone in ten seconds, why keep cash in a drawer at all?
For many businesses the honest answer is that you need far less of it than you used to — but rarely zero.
| Situation | What usually works better |
|---|---|
| Paying a supplier or anyone with an account | Online transfer. Instant record, no counting, no receipt to lose. |
| A shop or stall that takes QR | QR / e-wallet from a business account — but the transaction record is not a receipt. Still get one, still write the voucher. |
| Parking machines, small stalls, tips, cash-only trades | Cash. This is the shrinking but stubborn core that keeps petty cash alive. |
| Staff paying out of pocket, claiming later | An expense claim — same discipline: receipt, approval, reimbursed from the box or by transfer. |
Can petty cash be digital? Yes, and increasingly it is — a small dedicated e-wallet or a separate debit card used only for small business costs works exactly like a cash float. The rules don't change: one fixed limit, one responsible person, a record and a receipt for every payment, reconciled monthly — exactly as you would reconcile the bank account. Digital makes the recording automatic; it does nothing about the receipt or the approval, which is where the value was always sitting.
The trap in going digital. A bank or wallet statement tells you money moved and who to. It doesn't tell you what for or who approved it — and "PARKING SDN BHD RM8" is not a business purpose. Every business that thinks it has abolished petty cash paperwork has usually just moved the same gap somewhere harder to see.

15. Moving petty cash off paper
Paper vouchers work. They just don't add themselves up.
The step most businesses eventually take is recording petty cash where everything else already lives, so the small spending appears in the same expense reports as the big spending. In Niagawan Plus, petty cash is set up as its own payment source — alongside your bank accounts — so every payment from the box is recorded against it and flows into your expense analytics and financial reports. You can see what the box actually went on this month, by category, without adding up a pile of slips.
Niagawan Plus is RM497 a year with three user IDs, and includes sales and expense analytics, financial reports, AR/AP aging, digital invoicing, bank reconciliation, and automatic tax and zakat reports. Built for Malaysian businesses — RM, SST and e-Invoice handled — and used by over 40,000 businesses since 2016.

16. The five rules, in one screen
If you remember nothing else from this page, remember these:
✓ One fixed amount. Decide the float, and keep it there.
✓ One person responsible. Not "whoever's around".
✓ A voucher and a receipt for every payment. No receipt, no reimbursement.
✓ Approved by someone other than the person taking the cash.
✓ Count monthly, and top up only what was spent.
Petty cash is the smallest pot of money in your business and the easiest to lose track of. It doesn't need a complicated system — it needs those five habits and about five minutes a week. Do that, and the RM8 parking and the RM45 courier end up where they belong: in your accounts, as expenses you can actually prove.
Bryant Gan is the Founder of Niagawan — the cloud accounting and POS system used by more than 40,000 businesses in Malaysia since 2016. He has spent over 10 years building software that helps Malaysian SMEs keep their books, stock, and tax records in order.
Frequently asked questions
What does petty cash mean?
Petty cash means a small amount of cash kept on hand by a business to pay for minor day-to-day expenses — parking, postage, small supplies — where a bank transfer or cheque would be impractical. In Malay it's wang runcit or tunai runcit.
What is petty cash in Malay?
Wang runcit, tunai runcit, or wang petty. All three are understood in Malaysian businesses. Maksud petty cash: wang tunai dalam jumlah kecil yang disimpan untuk perbelanjaan harian yang kecil.
What is another name for petty cash?
It's also called a petty cash float, a cash float, or simply the float. In Malay: wang runcit, tunai runcit, or wang petty.
Is petty cash mandatory?
No. No business is required to keep petty cash, and plenty run without it by paying everything through the bank. What is not optional is recording business spending — if you do keep a cash box, the money that leaves it still has to be accounted for.
What is a petty cash limit?
Two different limits, and it helps to keep them apart. The float is the total in the box (commonly RM200 to RM1,000). The per-transaction limit is the most any single payment may be — commonly RM100 or RM200 — above which it goes through the bank instead. Set both, and write them down.
How much petty cash is allowed?
There's no set legal limit. Most small Malaysian businesses keep between RM200 and RM1,000 — roughly two to four weeks of small spending. If you're topping up less than once a month, your float is probably larger than it needs to be.
Is petty cash an asset or an expense?
The cash in the box is a current asset on your balance sheet. What you spend it on becomes an expense in your profit and loss. Both are true — at different moments.
How do you record petty cash?
Record each payment on a numbered voucher with the receipt attached, log it in your petty cash book, and enter the expense categories into your accounts when you top the float back up. Under the imprest system the petty cash balance itself stays fixed.
Can petty cash be negative?
Not in reality — you cannot hand out cash you do not physically have. A negative balance in your records means something is wrong: a payment recorded twice, a top-up never entered, or money taken without a voucher. Treat it as a signal to count the box and reconcile, not as a number to correct.
How often should petty cash be reconciled?
Monthly at minimum, and always before a top-up — the count is what justifies the amount you put back in. Businesses with heavy daily cash use often count weekly. The point of counting frequently is that a difference found this month is still traceable; one found at year-end is not.
Can one employee keep petty cash?
Yes — one named custodian is the correct setup, not a risk. The control isn't having more people touch the box; it's that someone else approves the payments and someone else counts it. Shared access with no single owner is the weaker arrangement, because nobody is accountable.
Can petty cash be used to buy stock or inventory?
No. Goods bought for resale belong in your purchases and stock records, not in petty cash expenses. Putting stock through the box understates your inventory and distorts your cost of goods sold. Pay for stock through the bank.
Can petty cash be used for fuel?
For a genuine business trip and a small amount, yes — with a receipt and the trip noted on the voucher. But fuel is the classic slow leak, because a receipt alone doesn't show whether the journey was business or personal. If it's regular, a mileage claim or a fuel card gives you a much cleaner record.
Can I use my own money and claim it back later?
Yes, and it's common — but treat it exactly like any other petty cash payment. Fill in a voucher, attach the receipt, get it approved, and reimburse from the box. What you should avoid is a running mental tally of “the boss paid for it”, because that's the balance nobody can ever reconstruct.
Can petty cash be transferred back to the bank?
Yes. If you decide the float is too big, bank the surplus and record it as the reverse of setting the float up — cash out of the box, into the bank. Reduce the stated float to the new figure so the month-end check still works against the right number.
Is petty cash taxable?
The cash itself is not income — it's your own money moved from one place to another, so there is nothing to tax. What matters is the spending: properly recorded business expenses supported by receipts are treated like any other business expense, and undocumented spending simply cannot be claimed. This is general guidance, not tax advice — check anything specific with your tax agent.
Can petty cash be digital instead of physical cash?
Yes. A small dedicated e-wallet or a debit card used only for minor business costs works the same way as a cash float, with the same rules: one fixed limit, one responsible person, a receipt and an approval for every payment, reconciled monthly. Digital automates the recording — it doesn't replace the receipt or the approval.
Do I still need petty cash if I use online banking and QR payments?
Usually less of it, rarely none. Transfers and QR handle anything with an account behind it, but parking machines, small stalls, tips and cash-only trades still exist. Many businesses find they can cut the float substantially rather than abolish it.
What if a receipt is lost?
Write a short note on the voucher explaining what the payment was for and why there's no receipt, and have someone other than the claimant sign it. Keep this rare. If it happens often, the problem isn't the receipts — it's the process.
Do I need a petty cash book if I only spend a little?
If you spend from a cash box at all, keep the log. It takes seconds per entry, and it's the only thing that lets you answer “where did the RM300 go?” three months later.
