Asking for a contract extension is generally allowed on most freelance platforms, and many clients are open to it when the request is honest and reasonable. The issue is how you go about it. If both sides agree to extend the timeline, the platform usually supports that change without any penalty. But if a freelancer keeps asking for extensions without making real progress, the client may lose trust and it could affect your review. Have you ever had to ask a client for more time, and how did they respond?
