Experienced freelancers have long been used to the fact that English is the foundation of client communication. All major platforms like Upwork, Fiverr, Freelancer, and 99designs are English-speaking. The main language of clients is English, as technical tasks are written in English and communication is conducted in English. According to Upwork data, over 85% of orders on the platform are published in English, and freelancers with high English proficiency earn 30-40% more than their colleagues.
Grammar mistakes, incorrect tone, awkward phrasing, all of this can cost you clients and reputation.
