question. . .hopefully not a stupid one, but I'm confused.

Why is my order total lower than my revenue total? Shouldn't they be the same? Isn't Revenue the total before any expenses, which would be the same as the order total?

It says for the month of July:

Order Total: $521.82
Revenue: $607.08

I am totally confused by this??

Thanks!

Ok, I am a little closer. . I just calculate my orders and it seems my Revenue is correct because I collected a deposit for a cake order in the month of August, so I get why it's higher.. HOWEVER. . my Order Total for the month of July is off. When I calculate my order total it equals $551.82. . so it's missing a $30 order. . .how do I figure out where it is or what happened??
