Hi ArcMicrotech ,
Thanks for your post.
You can export filtering by date. You can read here how to filter.
Just use the default Orders template (or create a custom one) and filter by any order's date. You'd need to import the exported file to SpreadSheet software if you want to calculate totals per product.
You can also add the Sales last days field to a custom template, after setting the "Show sales in the last selected days" in ATUM -> Settings to 30 (or 31) days.

Best Regards,
José Andrés
