  1. What is the role of employees? You don’t mention it … 

    And what is the exact meaning of reverse bid? 

    1. In a system where the options are the same for both the administrator and employees, it means that both the administrator and employees have access to the same set of features or functionalities. Administrator is having full authority and employees having limited authority.

      In a reverse bid auction, the customer or buyer specifies the item or service they need, and potential sellers or suppliers compete by submitting unique bids. Unlike a traditional auction where bids increase, in a reverse bid auction, suppliers strive to offer the lowest unique bid. The customer then evaluates the bids and selects the supplier with the lowest unique bid as the winner.

  2. I’m looking for a similar system, but bidding at a lower price. Where the buyer customer posts an order. schedule day and time to open the electronic trading session. Then the customer supplier bids the lowest price. Your system is able to do this

    1. The card details you entered in that is only for testing purpose. In haraaj project (Project Type 3) – it has live payment gateway. But you need to purchase payment gateway from paykun providers. They given one api key. you need to integrate that.
