Hi I want to know localization available in EU countries product like Austria, Holland, Hungary, Luxembourg, Germany, Spain

There is no specific feature for those countries. You have setup the tax rate manually.

Company only offers 3 specific versions for Europe

https://quickbooks.grsm.io/France

https://quickbooks.grsm.io/Ireland

Hi 

Thanks for replying So will the setups would be customized by QBO for all those EU entities which do not have separate versions or do we have to take up on our own. Are their 3rd party providers who would integrate those entities with the level of localization required for such EU entities. Please advise

To record the sales tax/VAT/GST, mostly we can use apply this reference

To record the Withholding tax, you should carefully learn the following reference

https://quickbooks.intuit.com/learn-support/global/tax/how-do-i-record-tax-withheld-by-my-customer/0...

Frankly it is not applicable for many countries due to we have to record it as liability.

You may explore any tax management application available in your countries. If it doesn't support QuickBooks, you may utilize a 3rd party importer tool.
