The main costing reports in Breww are the following:

You can view expected costs for a batch of a beer/recipe by going to Recipes -> Cost report, where Breww will run an expected cost report for that specific recipe. There you can also enter the expected wastage amount and tweak the expected ingredient costs to see the effect on the cost forecast.

The "Product expected cost breakdown" report in Reporting -> Production & inventory reports will show the expected ingredient costs based on the beer's recipe and the packaging costs based on the product's stock items if they have been entered in Breww.

The "Actual batch costs" report can be accessed by going to Production -> Batch # -> Reports -> Cost report. This will show the actual ingredient costs of the batch, packaging costs and duty, as well as your utility costs if they have been entered in Breww.

The "Margin by invoice" and "Margin by customer type" reports in Reporting -> Sales reports will use the actual costs and sales price to calculate margins.
