I have an inquiry regarding the use of third-party premium plugins for theme requirements.
Let’s say I submit a WP theme that requires the Gravity Forms plugin (3rd party premium plugin). However, I don’t include the Gravity Forms license with my theme.
Instead, my theme buyer needs to use or purchase their own license for the Gravity Forms plugin.
Is this allowed? or has any theme implemented this approach on Themeforest before?
It would be probably rejected if your theme depends on the plugin and even if the reviewer misses it, you will have bad rating/complaints about the problem and at some point, your theme will be disabled.
If you’re using a third party plugin that would require purchase, you will have to have the proper licence to sell it within your theme.
Does this mean it is not allowed? Is there documentation that mentions this? I have only found information for third-party free plugins but not for premium plugins.
This is a similar case to some Elementor template kits that require Elementor Pro, but this time for WordPress themes. On the template kit, the buyer needs to use or purchase their own Elementor Pro license.
The features you’re offering with the theme has to be included/covered by the plugins and you have to add the “premium” version if you’re including the features to your theme.
Have you ever seen any theme with “Slider Revolution” but not included to the download? Question your logic.
I think same thing for your one. You have to get license permission to use the Gravity Forms plugin in your theme. and you have to clearly mentioned in your theme page that customer of your theme must have to purchase the Gravity Forms plugin license to use the plugin and this plugin is mandatory. But it will negative effect for your theme and may cause negative ratings, refund request etc.
