I have used express invoice for some years now. really only to keep inventoria stock levels correct as it is not my main book keeping software.
However, it has a 10 year history of every sale I have made and is starting to run slow, would like to just start a new financial year so it doesn't have to troll through every invoice every time I make a new entry.
Thought of doing a back up and just deleting all previous invoices but is there a better way?
Thanks in advance
