Native English speakers tend to overuse Italian pronouns. Since verbs are conjugated in a specific way, using most pronouns is usually overkill. A pro can write in a fluent way that really reflects your message well.
Just like English, Italian uses abundant prepositions. And also like English, there are virtually no rules and a ton of exceptions to which pronouns to use in different situations.
Italian uses a lot of double consonants in words. This is a big trap for language learners since if you omit a single consonant, you go from penna (pen) to pena (pain).
Unlike English and Spanish, plurals in Italian are not formed by adding the -s or -es. Of course, mistakes are OK when you're learning a language, but not in official company communication or emails.
Nouns, pronouns, adjectives and even verbs have to take into account whether something is male or female. If you're not careful, it’s easy to insult a potential client. Hire a pro so you Don't have to worry about it.
Italian uses of lot of harmless sounding words in ways that get learners into trouble. Instead of running the risk of losing valuable business, find a certified translator and impress your clients instead.
Translators know business terms that are confusing for amateurs.
Remember that speaking Italian and translation are different things.
