Setting realistic expectations about project timelines, deliverables, and revisions is crucial to building trust and ensuring smooth collaboration. Many freelancers use contracts or service agreements to outline project scope and avoid misunderstandings. Additionally, they may collaborate with frontend developers, designers, or other freelancers, making strong communication and organizational skills essential for successful project delivery.
