I've found most users don't know about a report that shows sales that have been left open, incomplete or with some problem. Open the Reports window and it's at the menu Sales / Incomplete Sales (or Incomplete Tickets). Sales that have been left 'dangling' can actually slow down your system over time. Try out this report. It's not new, June of 2017. If the report list problems, there is a new function in the Tools / Optimize and Fix (Jan 2020). This will list the problems and give you options to fix them. Give it a try. And always do backups which are now automatic (Jan 2020).
