Hello Reidsinger, 

Thanks for your feedback, we will note your comment. Following what Emma has previously advised, We can advise of two options for you as a workaround if you wish to use them.

You can run a sales by customer detail report(from the reports section on the left hand side) and use the customise in the top right of the report>then in rows /columns>change columns>put a tick in the vat code box>run report. You can then export this to excel

You can also export from the all sales>all sales,then use the filter above the word date,filter the type to just invoices you can then export that to excel in the arrow on the right right side next to the print symbol. However this section does not have the ability to add in a vat code column. Thanks
