About this guide

Prepare a project brief with the source and target languages, intended audience, file types and required delivery date. Explain whether the material is for internal use, publication or submission to a particular organisation. For repeated work, share approved terminology and existing translations that the agency should follow. Ask how the agency handles specialist subject matter, revision and quality checks. Confirm whether desktop publishing, formatting and updates are included in the quote. If an organisation requires a particular form of certification, obtain its requirements before ordering and ask the agency to confirm that it can meet them. Discuss confidentiality and file transfer arrangements before sending sensitive documents.

Some agencies offer both, but availability differs. State the languages, subject, event format and document requirements so the agency can confirm its scope.
