Reviewers describe Rolly as a simple, helpful tool that saves time on invoice work, especially for people who need to prepare documents for others, like marketers working with content creators. Users say it is easy to use and friendly from the start, with one reviewer noting it has held up well over a couple of weeks of use. Feedback is sparse and almost entirely positive, so the clearest takeaway is narrow: reviewers value Rolly most for making invoicing easier and less time-consuming.
