Translation work varies widely by client, language pair, and scope, yet many tools force rigid billing models. Platforms like Upwork handle payments but limit flexibility and ownership. Tympi gives translators full control over how they bill: by word, hour, or project. Each assignment becomes a project with separate time logs for translation, review, and revisions. This level of detail makes invoices clearer and more defensible, especially for international clients. Compared to Upwork, Tympi keeps translators independent, professional, and in control of client relationships. The result is simpler billing, clearer communication, and fewer disputes across borders.
