What is Petty Cash?

Petty cash is a small amount of physical cash kept on hand for minor business expenses that are impractical to pay by cheque or electronic transfer.

Petty cash is a float of physical cash maintained for small, incidental business expenses. Common petty cash purchases include office supplies, postage, taxi fares, parking, small refreshments and other items under a set threshold (typically $50-$100). The petty cash system uses an imprest system: you start with a fixed amount, spend from it (keeping receipts for every purchase), and when it runs low, you replenish it back to the original amount. The replenishment amount should equal the total of all receipts since the last top-up. Petty cash requires its own account in your chart of accounts and should be reconciled regularly. Every transaction must be supported by a receipt or voucher showing the date, amount, purpose and who authorised the expenditure. Despite the small amounts involved, petty cash should be managed carefully as it is vulnerable to misuse. SortBooks helps by suggesting the right accounts for petty cash replenishment transactions in Xero, while you still check the balance against physical cash on hand.
