For sales via Smashwords other retailers though, reporting time varies tremendously. I've copied the chart (below) that I see in the Smashwords Sales and Payment Report to show you what I mean. Note the second column in the table, which shows the date for which sales are reported for that retailer. Barnes & Noble is the quickest, followed by Sony and Kobo, but Apple and Diesel are way behind, with Amazon bringing up the rear (except of course I'll never see Amazon numbers in this table because I'm selling direct via KDP). The fourth column shows actual dollar amounts for any sales not already reflected in my Smashwords balance (i.e., money that will be due to me from Smashwords after they get it from the retailers). All data is as of today, but I've zeroed out all the last column numbers.
When I looked at the sales and payment report in my Smashwords Dashboard, below this chart is a much longer and more detailed one showing sales by date and by vendor. It's actually pretty informative in terms of what titles are selling well, and in some cases, where. Apple and Kobo show the country where the sale was made.and all of them give you the price paid and the date.
