I’m using v4.5.5 on my self-hosted system. I started testing the application and therefore I created 2 invoices. Then I added my real clients and generated real invoices. The problem now is that I have the wrong invoice numbers in the application.
I’ve found no way to delete/reset the invoices. The only way that I see it to completely remove all data (delete DB?) and import the backups from the customers, products, and so on (except the invoices). Then I would have to manually create each invoice (which would not be a big problem). I would only use this option if there is no other way to reset/delete every invoice completely from the system.
What are my possibilities to start with 0 in the invoice counter?
