Redline Version is a business term used to describe the process of marking up changes made in a document and then sealing it, so that all later versions are tracked against it. In a redline version, deletions are marked with a line through them and additions are noted in a different color. This creates an easily visible comparison between various drafts of a document, allowing collaborators to glance at what was changed without reading through the entire document. It also provides a permanent record of how a document has evolved over time. Redline Version is valuable for businesses dealing with contracts and other legal documents, where accuracy and precision is critical.
