Posting to Indeed is free with AvaHR. Indeed is one of the 50+ free job boards your job goes out to when you publish, so you do not need to post there yourself.
Free vs. sponsored
A free listing works well, but if you want more visibility you can feature or sponsor your job. There are two ways to do that in AvaHR.
Ava Select Boost
On the Distribution step when you post a job (or a job's Advertise menu), turn on Ava Select Boost. It is $99 one time for 30 days of featured placement.
Paid job boards
On the same Distribution step you can add individual paid boards, each running 30 days. Add the ones that fit your role and budget, review the Boost Summary, and post.
So basic posting to Indeed is free, and boosting for extra reach is a paid add-on you control.
