Without a lot more background on just what you are doing, think a set of income and expense accounts should get you started. You are anticipating income from this activity??
If this is a business, and you expect to repeat these efforts for future plays, I would suggest introducing classes to distinguish between plays. You would use your standard set of categories for income and expense and simply append a class to keep track of which play was involved. Example; supplies for Fiddler On The Roof would be categorized; 'Supplies/FOTR' where FOTR might be shorthand for Fiddler...... Rental for Cats would be Rental/CATS and so on.
A Class Report for FOTR will summarize all income/expense associated with that play. An itemized Category Report. subtotaled by class, gives a report for all income/expense subtotaled for each play. I assume these activities are being co-mingled with normal household items so some customizing is necessary to filter out non 'business' activity for the example reports.
