Report Pundit: Custom Reports

This app is amazing- it allows reports based on fulfilled dates which is critical if you have delayed order, changed orders or cancelled orders . If you receive an order in may and ship in June the sale shows up in May reports even if you havnt shipped
Pundit support is the best- you just ask and you have it-they have created all my custom reports based on fulfillment date now I can determine my actual monthly sales. And their pricing is very reasonable
