Can Research, Supplemental Funding and Peer Review expenses be invoiced together in one submission through PCORI Online?

All funding categories can be invoiced at the same time in one submission through PCORI Online. The system has three designated boxes/areas for entering Research, Supplemental Funding and Peer Review expenses se. However, the billing period can only be entered once in the system per submission; therefore, if the billing periods of the three funding categories differ, this should be noted on the actuals invoice(s) or in a separate note uploaded along with the invoice submission.
