Various embodiments of systems and methods for inventory verification using inventory snapshots are described herein. In response to a first inventory posting in a current time period, a current open inventory snapshot is created with inventory information. If there is a previously open inventory snapshot that is created in a previous time period before the current period, then the previously open inventory snapshot is closed. To verify inventory for a past time period, a difference between an inventory snapshot that is valid for the past time period and an inventory snapshot that is valid for a time period previous to the past time period is compared with aggregated inventory change confirmations posted in the past time period. An error indicator is provided if there is a mismatch between the difference and the aggregated inventory change confirmations.
