Start New Financial Year

[deep six]

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
