How to cange default VAT rate in Billing module

[adrigen]

How can I change the default VAT rate?
I found a thread saying to do this in MYSQL:

UPDATE invoice_item_template SET vat = 15 WHERE vat = 19;

However 0 rows are effected when I do that. Is that info out of date?

You must set the VAT for each item template in ISPConfig.
