What does your Tax advisor use, post mail?

"extremely complicated to use" well, that is something that you hear often from Tax advisors or tools for less than €30. Same FUD tactics.

Germany has ELSTER, which is a free government provided online service. I use it every year to fill in my tax declaration. It's not perfect but it works pretty good. Not so friendly for expats since it doesn't have internationalisation, so you need to know a bit of german (I use G translate).
