The “Offers” tab has been specifically designed for the bidding system.
The bidding system is part of the broadcast feature found in the Admin Panel under “Settings - Dispatch - 2. Assignment - Auto Dispatch - Broadcast” https://admin.taxicaller.net/admin/settings/dispatch.php
This allows you to have the system broadcast all jobs instead of sending them to individual drivers. The jobs get broadcast to multiple drivers at the same time. A broadcast offer will appear only in the “Offers” tab, unless you have enabled the option *”popup.” When a broadcast jobs is offered, each person gets to bid on it if interested, or decline to remove it. If you bid on a job, you are expressing interest.
