import invoices

What is the source of invoices you want to import.

Currently WP Invoice allows you to import invoices from another WP Invoice powered site. This ability is available in WP Invoice Power Tools add-on.

I have the same question. I would like to do it manually without using the add-on.

I have moved all iles from old host to new host. I also copied and imported the SQL table called “wpi_object_log”. The file imported fine and I can see the entries in the new table, but wp-invoice does not see them. Is there a way to get them to show.

The answer to your question is above. Add-on does it in proper way. Otherwise you have to import whole database to make it work.
