Petty cash can become disproportionately difficult to review because many small transactions are handled away from the main bank feed. A neat-looking balance is not enough on its own: the bookkeeping file needs a traceable connection between money issued, purchases made, evidence retained and cash remaining. A structured review makes differences visible before they become part of the next period.
Establish the opening position
Begin with the prior agreed closing balance and the records showing cash added to or removed from the float. If the opening position itself is uncertain, record that as an unresolved point rather than treating the latest cash count as proof of what happened earlier. This creates a clear boundary between inherited uncertainty and current-period activity.
Match vouchers and receipts to recorded movements
Work through the petty cash record and connect each expense to the available receipt, voucher or other supporting evidence. Check dates and values, and note where the description in the record does not provide enough context. A receipt can support what was purchased, but the business purpose may still need clarification from the client.
Keep missing evidence on an exception list
Do not let a missing receipt disappear inside a general note. Give the transaction a reference and record exactly what is missing. This allows the client to respond to specific questions and helps another bookkeeper understand the outstanding issue without repeating the entire review. If evidence later arrives, link it back to the same exception.
Compare the physical or reported cash balance
Where the client provides a cash count, compare it with the balance implied by the records. A difference is a fact to investigate, not an explanation in itself. Check for unrecorded top-ups, expenses entered twice, omitted vouchers or timing differences that the available evidence can establish. If the reason remains unclear, preserve the difference as unresolved rather than inventing a balancing story.
Distinguish reimbursement from petty cash spending
Small expenses can enter the records through several routes. An employee may spend personal money and seek reimbursement, while another purchase may be paid directly from the cash float. Mixing these routes can create duplicate expense records or an incorrect cash balance. The review should identify how the payment was actually made before deciding which record it belongs to.
Control corrections visibly
If an entry needs correction, retain enough information to show what changed and why. Avoid simply deleting an inconvenient line from a working record with no explanation. The corrected position should connect back to the evidence or client clarification that justified it, particularly where the change affects the cash balance carried forward.
Agree a practical collection routine
Repeated missing petty cash evidence often points to a process problem rather than a bookkeeping problem. The client may benefit from one agreed place for vouchers, a simple reference on each record and a regular point for submitting documents. The routine should fit the size of the activity; an elaborate system can create more friction than the float itself.
Close only when the balance and exceptions are understood
At the end of the review, reconcile the recorded balance, the cash position supplied by the client and all known outstanding items. Any unresolved difference should remain visible to the responsible person. A useful petty cash close is not one that forces the numbers to agree; it is one that shows clearly what the evidence supports and what still needs an answer.
