Translation of Handelsbilanz

I wanted to tell you that we have uploaded a successful version (with Peter). In Annex I send the profile. It is very similar to the last version, just a few words less in each lesson.
Maybe we would need to say install our dictionary as a software? But I would say instead of install, use our dictionary as a software. So bottom line. If I use the singular form for newsletters and websites, I am on the safe side for both?
I am also your friend now, how nice is that. I am learning English for a year. I love this language. I already can speak Spanish, because my mother is from Mexico. Your German is really well!
