reversing a customer invoice

["Tobias McNulty" <..hidden..>]

I made a duplicate entry of a customer invoice and am trying to figure out
the right way to get rid of it.  I entered reversing transactions for all
the corresponding accounts in the general ledger.  It seems to work but
there are obviously still 2 invoices there, which is kind of confusing
when it comes time to actually invoice my customers.  Is there a better
way?

Thanks,
Toby
