Steuer program POD

[Kaufy]

Moin! 
I have a new shop on Shopify, doing POD. 

Currently delivering in the EU and a bit INT. 
I would like to find a good steuerprogram that can support me with Umsatzsteuervoranmeldung, Gewerbesteuer, Steuererklärung, etc. I looked for several programs, but I cant find the one that supports my business perfectly. 
e.g.: Taxdoo - doesn't support POD or sales outside of the EU

Accountable - don't support POD it seems or lacking integrations 

Does anyone has experience with LEXOFFICE, WISO BÜRO, SEVDESK, ACCOUNTABLE, etc. and can recommend? 

1. EU + International sales 
2. POD business  

Thanks!
