A default VAT Exempt ID can be set in the invoice settings

Customers can be marked as VAT exempt in the Add/Edit Customer section.

When a customer is VAT exempt, their VAT rate will be automatically set to the one configured in the invoice settings.

When creating a contract invoice for a VAT-exempt customer, the exempt VAT Rate from the invoice settings is automatically applied.

Quote Notes now include the option to add private notes using double brackets, which are not visible to customers. Any text enclosed in double brackets will not appear in quote reports.
