Since we’re mapping your sales data directly against your inventory usage data, it’s important to have the same date range so that it doesn’t create any false variance…If your inventory period is a day longer than your sales report’s date range, there will be usage from that day that isn’t accounted for in your POS item-level sales report.If that POS sales report is a day longer than what your inventory period is, there will be sales data from that whole day that your usage isn’t accounting for.
