Upgrading or Downgrading between Clockwork Pro and Free apps

Clockwork Automated Time Tracking & Timesheets can be purchased with all features, or used as a limited Free version. See this page for a comparison of available features.

You can move between Clockwork versions without losing your worklogs data. Worklogs will be available on the timesheet once the upgrade/downgrade is complete.
Settings that available in both versions will be preserved when moving between versions.
Upgrading or downgrading between versions can be performed an unlimited number of times.
If your Jira instance is up to 10 users, Clockwork Pro will be free of charge for you although Atlassian will still display you’re in trial for the first 30 days as this is how it works for paid apps.

Upgrading from Free to Pro

Navigate to Jira Settings > Apps > Find new apps and search for Clockwork
Automated Time Tracking & Timesheets Pro.
Install the app. (Two Clockwork panels will be displayed on issue pages while both the Pro and Free versions are installed.)
Navigate to Jira Settings > Apps > Manage apps and uninstall Clockwork Automated Time Tracking & Timesheets Free.

Clockwork Pro is free for Jira instances up to 10 users. You will not be charged if you have 10 or less users. However, you should be aware that you might see a message from Atlassian saying you’ll be charged after the trial period - this message is displayed only because the app is Paid in all other user tiers. To check that you won’t be charged, click on Manage Subscriptions.

In Subscription details, you’ll be able to see your current subscription details. In case of any issues or concerns about your billing, you can reach out to https://support.atlassian.com/contact/#/.
