What is petty cash in simple terms?

It is a small amount of cash kept aside to pay for minor day-to-day expenses like fares, tea, stationery and courier, which are too small to pay by cheque or bank transfer.

How does the imprest system work?

You fix a float amount and give it to the petty cashier. They spend from it and keep vouchers. At period end you reimburse exactly what was spent, restoring the float to its fixed level, so cash plus vouchers always equals the float.

How much petty cash float should a small business keep?

Enough to cover a week or two of small expenses without frequent top-ups. Many Indian small businesses keep between ₹1,000 and ₹5,000 depending on how often small spends occur.

What is an analytical petty cash book?

It is a petty cash book where the total column is split into expense heads such as travel, office and miscellaneous, so you can see how much went to each category and post totals to the ledger.

Should petty cash be recorded separately from the main cash book?

Yes. Keeping a separate petty cash book stops many small entries from cluttering your main cash book, while still letting the totals post into your ledger and reports.

Petty Cash Management: Book, Imprest System and Format for SMBs

Every business spends small amounts of cash all day: tea for a visitor, an auto fare, a courier, some stationery, a few screws from the hardware shop. Individually these are tiny, but together they leak real money if nobody tracks them. Petty cash management is the simple system that keeps these small spends recorded and controlled. This guide shows you the petty cash book, the imprest system and a ready-to-use format.

What petty cash is

Petty cash is a small float of money, often kept in a separate box or drawer, used only for minor expenses that are too small to pay by cheque or bank transfer. One person, the petty cashier, looks after it and records every rupee that leaves. Keeping it separate from the main cash book stops small expenses from cluttering your main accounts.

The imprest system

The imprest system is the standard, sensible way to run petty cash. It works like this:

You fix a float, say ₹2,000, and hand it to the petty cashier at the start of a period.
The cashier pays small expenses from it and keeps a voucher or bill for each.
At period end, you count what is left and reimburse exactly what was spent, topping the float back to ₹2,000.

The beauty of the imprest system is that the float plus the vouchers should always equal the fixed amount. If ₹1,400 is spent, the box holds ₹600 in cash and ₹1,400 in vouchers, together ₹2,000. Any gap is caught immediately.

No voucher, no payment

Make it a firm rule: every rupee out of petty cash needs a bill or a signed voucher. This one habit stops the slow leak that quietly drains small business cash across India.

A petty cash book format

A common layout is the analytical petty cash book, where the total column is split into expense heads so you can see where the money went. Here is a sample:

At the end of the period, each expense column is totalled and posted to its ledger account, just like any day book entry flows to the ledger. If you want a refresher on how those postings pair up, see debit and credit.

Petty cash is small money, but sloppy petty cash becomes a real hole. Fix a float, run the imprest system, demand a voucher for every rupee, and record spends by head. Then connect the dots with the cash book format, the day book format, and our bookkeeping starter guide so your whole recording system holds together.
