Why petty cash goes off the rails
Petty cash often starts with the best intention: keep a small float on hand for stationery, tolls, parking, courier top ups or the odd urgent item. The trouble begins when there is no clear limit, no signed proof and no regular count. After a few weeks the tin, drawer or envelope no longer agrees with the records and nobody can say where the money went.
For a micro business, that does not sound like a disaster, but it adds up fast. A few unrecorded R50 buys, a missing receipt or a cash advance that was never settled can distort the monthly accounts and make it harder to see what the business is really spending. In a business with one or two staff, that can be the difference between knowing your margin and guessing at it.
Set a float that matches real spending
The first control is simple: decide how much petty cash the business actually needs, then keep it fixed. A Bryanston based team with a few daily expenses may only need R1 000 to R2 000 in the float, while a small workshop, salon or delivery operation may need a little more. The amount should match real use, not a vague feeling that cash should always be available.
Once the float is set, write down what it may be used for and what it may not be used for. That keeps bigger purchases out of petty cash and stops it becoming a back door for ordinary supplier invoices. If an expense is over the limit, it should go through normal approval and payment.
- Choose one fixed float amount.
- Keep petty cash for small, urgent items only.
- Set a maximum spend per transaction.
- Decide who may approve a cash issue.
Use a voucher for every payment
Every time money leaves petty cash, there should be a petty cash voucher or slip that shows the date, amount, reason, recipient and the person approving it. If the purchase is made in the local shop in Sandton or at a hardware store in Randburg, the slip and till receipt should be clipped together. If there is no receipt, the payment should not simply be left as is.
This matters because petty cash is not just about physical money. It is a record of small decisions. When each payment is backed by a voucher, it becomes much easier to review the month, spot patterns and catch errors early. It also makes handovers cleaner when someone is off sick or on leave.
- Record the date and amount.
- Note what was bought and why.
- Attach the receipt to the voucher.
- Get a signature from the person receiving the cash.
Count the cash before it disappears into the day
Petty cash should be counted regularly, not only when the box is empty. A weekly count works well for many micro businesses, especially where one person handles the cash and another reviews the records. The count should confirm the cash on hand plus vouchers equals the original float.
If the count does not balance, do not wait until month end. Check for duplicate slips, wrong change, or a voucher that was entered twice. In a small Cape Town office, for example, a misplaced R120 parking receipt can take longer to find than the cash is worth, but the habit of checking early prevents bigger errors from building up. It also helps during load-shedding days when routines are rushed and records get skipped.
Keep petty cash separate from daily spending
Mixing petty cash with normal sales takings or bank card cash back is where trouble often begins. Keep the float in one place only, with a clear custodian responsible for it. If more than one person needs access, each issue and return must be recorded. Do not let the cash drift between handbags, tills, glove compartments or different branches.
For businesses operating across Johannesburg, Pretoria, Durban or Gqeberha, this is especially important. A simple standard should apply at every location so the process stays the same whether the spend happens in the office, on the road or at a client site. That consistency makes monthly reporting easier and limits disputes later.
- Keep one custodian per float.
- Store cash in a locked place.
- Do not mix petty cash with sales money.
- Use the same process across all branches or sites.
Match the records before month end
A good petty cash system should be easy to reconcile. At month end, the total of the cash on hand plus approved vouchers should equal the float. If the business tops up petty cash from the bank, that top up should also be recorded clearly. This is where many micro businesses lose track, because the paperwork is scattered and the top up happens before the old vouchers are checked.
It helps to keep a simple spreadsheet or ledger with columns for date, amount, purpose, receipt number and balance remaining. Even a small business in Midrand with just a few weekly expenses can stay in control with that structure. The point is not paperwork for its own sake, but a clean trail that supports the accounts and makes tax time less stressful.
A local example from a small business week
Take a micro business in Bryanston with three staff, a courier run to Pretoria, a few parking costs and some office top ups. Without controls, the team may take cash from the tin for tolls, forget to attach a till slip for stationery and pay back the float only when someone remembers. By Friday the money is short and nobody has a full picture.
With a proper petty cash process, the same week looks different. Each issue has a voucher, receipts are attached, the float is counted on Thursday afternoon and any shortage is queried immediately. That does not remove spending, but it does remove the mystery. The owner can see what was spent, why it was spent and whether the amount still makes sense for the business.
For micro businesses, petty cash control is not about being fussy. It is about protecting small amounts so they do not become hidden losses. Tight controls, regular checks and clear accountability keep the books cleaner and the month easier to close.
