OpenAIRE has now signed pre-payment agreements with BioMed Central, BMJ, Copernicus, Ubiquity Press and Wiley on behalf of the EC FP7 Post-Grant Open Access Pilot. These will allow APCs for eligible articles published in any of their fully Open Access journals to be charged to the pre-paid account upon manuscript acceptance. In case the publisher has them in their portfolio, submissions in hybrid journals will not be accepted. 

Some publishers share information with us on submitted manuscripts which have acknowledged FP7 projects, but not all of them are able to do it. To ensure that your request will be processed and transferred to the publisher pre-paid fund, it is advised to submit a request through our system, but you don't need to upload an invoice. Upon revision, the reviewer will notify the publisher that the publication can be moved to the pre-paid fund. 

The same requirements apply to this type of funding than through the regular system.
