Compare the total number of quote cost centres created last month.

Beware that for quotes with multiple cost centres, this report will count each cost centre, not each quote. If the quote has an Electrical and a Plumbing cost centre, that will show one count in the Electrical and one count in the Plumbing cost centres.

When selecting a field to group by, always use the cost centre "Default Name", otherwise if you have renamed the cost centres they won't show correctly in this report.
