Unfortunately, correct spelling, grammar and impeccable style are in danger of extinction. At the same time, they are an essential element of corporate life. Here’s a solution to this dilemma: just hire a language purist who is allergic to spelling and grammar mistakes as well as stylistic atrocities, but who will polish your copy without lecturing you.
Choose between these two options: grammar and spell check, including punctuation, sentence structure, verb tenses, tense consistency, etc. (proofreading) or all of the above plus content editing: improvement of style, correction of redundancies and repetitions, syntax, improvement of comprehensiveness, etc. (editing).
When proofing or editing German-language texts, I observe the new German spelling rules (final reform as of August 1, 2006, with minor changes as of 2024). I will also be happy to include client-specific wording, e.g. women-friendly language.
