Report Pundit: Custom Reports

Overall the app is tremendous and provides extensive reporting capabilities that you can't get from the standard Shopify plan. We use it daily for mission critical reporting. They have a slew of pre-made reports, but it helps to know some basic programming to really leverage the power of the app. They have some issues with data feeds -- both from Shopify and also when exporting reports on set schedules to Google Sheets, but they have very responsive customer support and most issues are resolved within 24 hours.
