What does "number of scheduled posts" mean?

Depending on your Buffer plan, you will be allowed to store a certain number of posts in your queue at any one time.
  • Individual Plan: 10 posts
  • Awesome Plan: 100 posts
  • Business Plan: 2,000 posts
  • Enterprise Plan: 2,000 posts
Let’s say you are on the Awesome Plan and already have 100 posts in your queue. You will not have the option to add any more posts. However, as soon as one of your posts gets published, you’ll be able to jump in and top your queue back up to 100. If you share 10 posts per day, you would be able to schedule 10 days in advance on the Awesome Plan.
