How are Document Translation Services billed?
Document translations are commonly billed on a per word basis with a minimum fee that covers up to ~350 words. For most languages, it is the word count of the target language (i.e. the word count of the completed translation) that applies. However, if the target language(s) are character-based (Japanese or Chinese, for example), the word count is based on the number of English words regardless of the direction of the translation. This is also the case if the target language is particularly compound-rich, such as German or Hungarian. At ASTA-USA Translation Services, Inc., we include the editing/proofreading and certification fees in the per word rate quoted to the client, since our thorough document translation process consists of three stages (translation, editing/proofing, final review/certification). If you have an already translated document and would like it reviewed, please see the answer to Do you provide editing and proofreading services? below.
It depends upon the translation service provider. Some companies bill according to the length of your data. These charges are different from language to language that is translated. While the other companies follow their own rules. The Translation Excellence Inc. charges minimum for document translation. For more details visit.
