All PLR and Commercial products from Simply Couture Designs PLR include Commercial License rights.
This means that you can customize the planner template source file and re-brand it to sell the finished flattened planner PDF as your own product.
The only thing is that you cannot sell the template source file itself and you cannot sell the finished planner with re-sell right.
For detail of the license, please refer to the License File that comes with each PLR and Commercial product download.
Thank you.
