Commercial License CreationYou can create your own commercial license package through the Steamworks partner site by navigating to your titles landing page and selecting "Create Commercial Package" under the "Store Presence" tab.
Note: This option is only available if you're already selling a regular end user version of the app on Steam. You won't see the Create Commercial Package button until after you launch your game.

If your Steamworks partner has already signed the Cafe Distribution Addendum, you'll be able to proceed and create the package. If not, you'll see the requirement to sign that Addendum.
The Addendum covers the licensing and agreement terms to sell a Commercial package. It's necessary because the initial Steam Distribution Agreement only covers personal, non-commercial copies that you sell to normal end users.
Please note: only the Actual Authority account from your Steamworks partner will be able to complete the agreement signing process.
Once the Cafe Distribution Addendum is signed, you will be able to create a Commercial package, and continue with the process of setting a price.
We recommend offering the commercial license at the same price as the regular end user version.

Prices will then get approved by Valve.

As soon as the prices are approved, you will be able to publish the license by selecting "Release" next to the commercial license package.

Your game's commercial license will now be displayed right under the regular end user purchase option and will only be visible to licensees of the Steam PC Café Program.
Special Content for Commercial PackagesSteam allows publishers and developers to add special features or additional content just for Cafés by making a new package and defining the content to be included in the package. We encourage developers to consider this as a way to tailor their game for use in a Café. The commercial version should, at a minimum, include the same game content as the regular end user version.
