Make sure that the bank information entered is your institution's and not the publisher (as they have already been paid!)
Invoices and requests for reimbursement should always mention our VAT number, but can under no circumstance contain VAT.
Regardless of whether the invoice has already been paid, a funding request should always be submitted through the central system for any payment to be made from the FP7 Post-Grant OA Pilot."
