Your JSS reflects your overall contract history with your clients on Upwork and is based on your (or your agency's) relationships and feedback. It takes into consideration a number of different factors, including public and private feedback, contract-ending history, dispute history, and long-term customer relationships
We calculate JSS daily based on your 6-, 12- and 24-month history in the marketplace and calculate a score for each timeframe. The best score out of these will display on your profile.
At a high level, we look at JSS this way:
(successful contract outcomes - negative contract outcomes) / total outcomes
