We have currently started using the Import Plus utility and it works great! I was just wondering how to make it to append to an existing invoice OR create a new one if it none exist.

-mode append didn't seem to work. I'm using 3p-invoice-basic-csv. Thanks!

You can't append to an existing invoice without writing some special code.

What I do is export the invoice, check that it has not been updated to the ledger, merge in the extra lines into a new source file then delete the original and import it all back again.

The default is to create a new invoice so you do not need to do anything.
