If you've completed an inventory count and are seeing a large variance that doesn't make sense, don't worry just yet!
It's possible there is just a bit of bad data getting in the way. Luckily, this is generally easily fixed!
Your variance is the difference between what was sold and what was actually consumed.
Whenever looking at variance, it will always come down to one of two cases:
Consumption is greater than sales (a negative variance, which means a loss)
Sales are greater than consumption (a positive variance, which means a surplus)
You want to make sure that your data is accurate so that you can identify whether it is a "true" variance due to overpouring/spillage/theft rather than bad data.
Potential Consumption Issues
Since the variance hinges on consumption data, it's very important to make sure that:
All items are properly counted during inventory
All invoices are added and dated correctly
Miscounted items and missing invoices account for the majority of consumption issues.

Potential Sales Issues
Since the variance compares your consumption to your sales data, it is very important to make sure that:
All POS Items are properly mapped
No sales data is missing
If a POS Item is unmapped, all sales for that item will not be factored into variance calculations. Without this step, there is no way to associate an item from your inventory to that sales item.
If the POS Item is mapped incorrectly, for example, you assign 2oz to a POS Item instead of 1oz, this will over-represent the amount showing in the sales.
