You can create one or more blacklists – or one for every call for bids if you want. You can save and re-use blacklists. The blacklist has to be created before your call for bids is published. Then when you publish your offer you can choose the blacklist.
Want to create a blacklist?
Step 1: Click on ADD COMPANY BLACKLIST under ADVERTISE JOBS.
Step 2: Name your list and click on CREATE LIST.
Step 3: Add companies and click on SAVE.
You can edit your blacklist at any time and remove companies from the list, or add new companies.
