A clear statement of your requirements

A quality text; it will always be harder to make a good translation of a poor original

Information, documented where possible, regarding your in-house terms and titles

Recognition that quality work requires reasonable deadlines; time for translation needs to be factored into your lead times

Availability to answer questions, clear up ambiguities, explain and clarify where necessary

Confidence that our native speakers will not fail you; we would turn down the work rather than take that risk.
