I mean version of VM Invoice. Do you have 2.0.16 OR any older version?
Some calculations for your invoices. Subtotal is 12.50 and it is right. You can also show subtotal excluding tax, if you set it in configuration. But last column will be always subtotal with tax. We can make this as a new feature for next release.
12.50 is price for 5 items, so 1 item costs 2.50. Item price excluding tax is 2.358 rounded to 2.36.
Subtotal excluding tax is 11,792 and rounded it is 11,79
Only tax is wrong (should be 0.71 as a rounded number), but your template on printscreen doesn't look same as I checked it in the newest version. So maybe update for your VM Invoice will repair old bug? You can check it.
If you need modifies for your installation of VM Invoice immediately, you can write to
