Bookkeeper cannot reconcile a petty cash register where a customer's deposit and an ATM withdrawal are both recorded as transactions in the same account, creating a net-zero but conceptually incorrect balance that cannot be resolved without throwing off other accounts.

Existing accounting software lacks a straightforward way to handle scenarios where a client receives a petty cash fund via electronic transfer and then withdraws cash; the software treats both as separate register entries instead of linking them as a single reclassification.
