# Concurrency SLA

> Learn how concurrency is calculated in Paragon.

Paragon's concurrency SLA is the number of [step executions](/workflows/viewing-workflow-executions#detailed-task-execution) that can run at a given time across all of your [Connected Users](/billing/connected-users). For example, if you have a concurrency SLA of 20, you can have up to 20 step executions running in the background at a given time.

### Concurrency Levels

Our Concurrency SLA for our standard plans is as follows:

| Plan           | Concurrency SLA                 |
| -------------- | ------------------------------- |
| **Trial**      | **5** step executions           |
| **Pro**        | **20** step executions          |
| **Enterprise** | Up to **1,000** step executions |

Enterprise customers may contact their Customer Success Manager to configure their Concurrency SLA.

### What happens if I reach my Concurrency SLA?

When you exceed this SLA, new step executions will be queued up for execution and show as `Not Started` on the [Monitoring](/workflows/viewing-workflow-executions) page, under the Workflows tab. Paragon accepts and stores all executions and will only execute them once the concurrent workflows drop below the SLA limit.

  To upgrade your Paragon subscription to a higher usage tier for concurrent workflows, [contact Sales](mailto:sales@useparagon.com) or reach out to your Customer Success Manager.
