There are two types of Tasks on Hyer, Hourly and Fixed-Fee. Fixed-Fee Tasks have a fixed price and an estimated completion time. This estimation is based on experienced Taskers, so as you start learning it may take longer to complete these Tasks then the estimated time listed. You are being paid for a specific number of deliveries or activities, not for the time spent accomplishing them. These Tasks are not subject to any increase in pay if the Task goes on longer than the estimated time listed.
