hi looking to see if it would be possible to wipe all invoices in and out on my account as i was using it for demonstration purposes and now i would like to use it going forward many thanks Seán

Sure. Are you a limited company?

Great. In the top bar beside your name you'll see a drop down. If you click that you can create a new company.
Click the cog and in this old company and in company info change this company name to "delete".
I'll delete it tomorrow.

Coolio. All the best is Biz Sean.
