Time in queue
You may confirm a deal with your buyer now and start working on the project later.
For example, buyer is ready to confirm the order today, but you are free to this project in a few days.
With this setting you can specify a "time in queue" to prepare for this project.
1. Zero (0)
You will start to work on this project immediately - right after buyer confirms the project
2. More than zero
Buyer will be notified that you enqueued this project and you are preparing for work. Make sure to start working on this project before the deadline. Because if you don't, buyer has a right to request a refund.
