There are a few different tools for you to learn about your sales.
If you're interested in seeing how many sales you've had for your book in the last 45 or 90 days, check out your Sales Overview page. This page allows you to view your sales data by project or all projects together. It shows sales by each selling channel and even includes the information about your own purchases.
Monthly Profit Reports
Your Monthly Profit Reports show you the profit earned for your book sales. If you're looking for new sales, check the pending tab to see recent sales. Profits stay on the pending tab until the transaction closes. Blurb sales are considered "closed" in the month when the order ships. Sales through Amazon and Ingram "close" when we receive payment from them. Payments are sent at the end of the month.
The completed tab will show you profit earnings and payment information for previous months.
