When I look at the gross sales for the day in the app, it does not reduce the amount by the discounts on the transactions. Quite annoying seeing $2000 in sales when it might acutally be $1600. Makes this feature almost useless. Any way to fix this? (it should be default too)
In Shopify parlance, gross sales doesn't account for discounts.
I believe what you are after is the net sales.
We also have a reporting app that can show daily net sales and pretty much any other metrics:
I hope this helps,
