Many companies and organizations believe that their bilingual employee is capable of completing their translation job. However, it’s difficulty for them to be their go-to translator. Case after case proves this usually results in a poor translation. A professional translator makes sure that the tone of your document is communicated appropriately. It won’t be too casual or too formal, and at the same time matching the tone of the source document. S/he can also assure you that words have been spelled correctly. Furthermore, they don’t have other responsibilities at your company that are being neglected because they’re trying to do your translation job (which they often feel unqualified for).
