Shortcode

Hello,

Thank you for your excellent plugin, well designed!
Unfortunately, this VAT plugins must be integrated (on connection) with invoices plugins, due to tax law.
I read on your website “Upcoming features: … integration with PDF Invoices and Packing Slips plugin.

I am wondering if this plugin can work with other invoices plugins, it’s possible to shortcode the vat number as [vat_number]. And how, I tried and didn’t work.

What is the shortcode for the vat number ?

Thanks for all
