What is a site imprest or petty cash fund in construction?

A site imprest is a fixed cash float given to the site engineer or supervisor to pay small, day-to-day site expenses, which is topped up to its original amount against vouchers when it runs low.

Site Imprest (Petty Cash) explained

Typical imprest spends are tea and refreshments, local transport, small hardware, repairs, loading and unloading, and minor labour. Large items go through vendor bills and proper approvals.

The imprest holder submits vouchers or bills for what was spent. The balance of cash plus vouchers should always equal the original float, which makes it easy to spot shortages.

Cash spent on sites is where small leaks hide. Entering site expenses against the project the day they happen keeps them visible.

How ARC PEM helps

Site engineers and supervisors can enter site expenses against the project from a phone, and payment approvals and a change history for each entry keep the cash trail visible to the office. See all features.

Frequently asked questions

How much petty cash should a site hold?
Enough for a week or two of small expenses, set by the firm. Keep it small enough that a loss is not serious, and top it up against vouchers.
How is site petty cash accounted for?
The imprest holder submits vouchers for each spend; cash in hand plus vouchers should add up to the original float, and the expenses are booked to the project.
