Can you please consider putting a warning message in enter sales for customers or items that have been ticked as inactive. This will save a lot of heartache. I know they don't appear in the drop do...
The warning suggestion would be an effective way to ensure the inactive card is not accidently used. It is frustrating enough having to wade through the cards - inactive & active to create a mail merge :( this should be a priority for those whiz bang programmers.
