Reports are pulled from Juice data live. If needed, data can be pre-processed to allow even faster reporting.
The answer is YES! Juice collects a wide amount of useful information allowing reports to be highly customizable and informative.
Juice reports can have a wide array of parameters, the most common being a 'From' and 'To' date. All you have to do to run a report is select your parameters and click run.
For large reports, such as detailed transactional reports, a web browser may limit your ability to analyze the data. Since Juice supports a wide variety of documents, this allows you run reports offline. They will quickly be run in the background and be made available to your personal document folder.
