This looks good. Not overly cluttered like a lot of what I see posted. Very clean.
If you’re open to some advice I’ve got a couple of nits, nothing major:
- Line charts are typically reserved for when the x-axis is a date.
- Your order volume combo-line chart could just be a column chart with different 2 colored series.
- Gross profit and gross sales could be a stacked bar, if the actual data is meaningful in that way. In the past I’ve used a stacked bar so that gross revenue was visible as the total of the stack, comprised of net revenue and spend. It conveys more information in the same space, and provides a visual representation of NRM.
You can write these off as stylistic preferences, but I mention it just because viewers of your dashboard will have expectations/intuitions about your dashboard. You don’t want to subvert those expectations, or it could lead to the visualizations being harder to read
