Duplicate Invoice GL Entries

Why are there duplicate GL entries for some of my invoices?

Whenever you edit an invoice, it makes a reversing set of entries to back out the original invoice amounts, and then it creates a new set of entries for the updated values. So in the GL it might look like duplicates, but the existing invoice GL entries are reversed out first before the next set is added.

Invoices that aren't edited won't have any additional sets of transactions in the system. This only applies to invoices that are unposted and modified.
