How do I add in taxes and where do I put my tax number so it’s in every invoice?
You can add taxes using the “Manage rates” link on the invoice creation page.
The tax number can either be stored in the VAT or ID number field in the Company Details (https://www.invoiceninja.com/company/details) or in the invoice footer (https://www.invoiceninja.com/company/notifications).
Does VAT have to be selected from the drop down for every invoice to apply it? Would be nice to be able to have VAT applied as default.
