Hi KerryG_25,
Welcome to the Community Forum!
Absolutely, you can customize your invoices. To remove the tags 'Purchase Order No' and 'Shipping Details', you'll need to edit your invoice template. You can also rearrange the layout of your business address and change the size and font of your business name and other details in the template settings. For more detailed information and steps, our help article on personalizing invoices is a good place to check out. Feel free to post again if you have other queries. We're here to assist you!
Kind regards,
Shella
