Invoice templates for freelance medical writers billing pharmaceutical companies, agencies, and healthcare organisations.
A medical writer invoice is issued by a freelance or contract medical writer to a pharmaceutical company, CRO (contract research organisation), medical communications agency, medical device company, or healthcare publisher for professional medical writing services. Medical writing encompasses clinical study reports, regulatory submissions (CTD, ICH guidelines), medical education content, journal manuscripts, healthcare professional communications, and patient information materials. Medical writers in the UK typically hold scientific or medical degrees (BSc, MSc, PhD, or MBChB) and many are members of the European Medical Writers Association (EMWA) or the American Medical Writers Association (AMWA). Good Clinical Practice (GCP) training is standard for those working in clinical trial documentation. Medical writing is a high-value specialist service. Regulatory writing for pharmaceutical submissions demands the highest rates, reflecting the scientific expertise, regulatory knowledge, and precision required.

Invoice at project milestones for large documents (clinical study reports, regulatory dossiers). A common structure is 30% on project commencement, 30% on delivery of first draft, and 40% on final delivery after revisions. For time-and-materials work (supporting ongoing regulatory programmes), invoice monthly for all hours worked. Keep detailed time records and attach a timesheet to your invoice. For medical communications agencies, confirm their invoicing requirements. Agencies often have specific project codes and PO systems. Ensure your invoice references the correct project code to avoid payment delays. Medical writing for regulated documents is subject to strict version control and audit trail requirements. Retain all draft documents and communication records as part of your project file.
