Yes, you may submit more than one invoice for the same billing period if expenses were missed on the original submission. Please ensure that the billing period entered in PCORI Online matches the billing period on the physical invoice attached to the submission. Note that PCORI Online will show a warning message alerting the user that an invoice for the same billing period has already been submitted, however the system will not prevent the user from submitting the invoice.
