This page explains how to manage Complementary activities in KA151 and KA153 projects, using a KA153, call 2023 project as an example. 

Complementary activities are side activities adding a value to the project and contributing to increase its impact (e.g. seminars, conferences, coaching) and can be added and managed under the specific tab in your project.

The indirect costs of complementary activities cannot be higher than 7% of the direct costs. The grant covers up to 80% of the total costs (direct + indirect), and the amount of the total eligible cost cannot be higher than 10% of the project costs. The total eligible amount is displayed in the project budget and the Complementary activities will also be available in the Final report.

Complementary activities can only be managed by associated persons with edit rights in the project if the project status is Project ongoing
