To see the number of Searches remaining on your plan and how the Searches have been used, click on your name in the bottom left corner and click Settings. In the Subscriptions sub-tab, you can find all this information and the option to receive a notification email when you have used 90% of searches. You can find the amount of searches you have left, the percent you have used, and when your next payment is.
You will also find your specific search usage for that billing period - whether it is from your website or your internal dashboard. Business website searches refer to searches made through your website widget. Deep Lawn Dashboard searches refer to the number of searches you have internally from the Dashboard search bar. If you have API activated, you will also see the amount of API searches.
