We offer a free revision of a text that we have translated, if it receives criticism related to language problems, on the condition that you have not made any additions or updates that involve grammatical errors on the file checked by a native speaker editor. We guarantee revisions within this scope. However, if phrases, sentences, and/or paragraphs with grammatical errors are added to the text or significant updates with such errors are made after we deliver it to you and this article is rejected because of these linguistic errors, this extra work is outside the scope of the guarantee, and we will charge you an extra payment for these parts since these added or updated parts will have to undergo a first check Native-speaker editors also regard such text as a new project and will need to be paid for it.
