We have project managers deployed in Europe, America, and Asia; this enables us to respond to your inquiry around the clock. The turnaround time for copyediting a manuscript will depend primarily upon its original quality and length. The majority of standard scientific manuscripts are returned within 3 – 5 days after completing the payment of your order; 24- or 48-hour express service is also available. For translation, the majority of standard scientific manuscripts are returned within 7-10 days after completing the payment of your order, and express service is not available. We work seven days a week (excluding US federal holidays) and try to accommodate your needs and wishes as much as possible. If you have an imminent deadline, we will make every effort to expedite the copyediting procedure.
