You can submit as many design requests as you need, and every plan includes unlimited revisions. What isn’t unlimited is how many requests can be in production at the same time, and that’s determined by the number of slots in your plan.
One slot keeps one piece of work in production at a time and typically delivers 15 to 20 tasks per month. The exact number depends on the complexity of your requests, the clarity of your briefs and how quickly feedback is provided.
If your workload grows, you can add more slots or use an Overdrive week for a temporary capacity boost.
