Hiring Settings
First of all please enable the hiring from Theme Settings.
Then go to Product/Packages section and create a hiring product for payments.
Please make sure you have checked the Hire Freelancer. Then set the price to 1 or what you want, this price will be overridden by the project price while hiring.
For example when an employer will hire a freelancer for the bid $100 then this product price will be overridden with the $100 and WooCommerce order will be placed with that custom price
No need to setup this checkbox for each product or package for freelancer or employers
