How do I submit a purchase order (PO) for the RC Core?
It is recommended that you provide a PO that will be active for 18 months, if possible. The HMS RC Core will accept POs only as the method of payment for labs external to Harvard. We will send invoices four times per year. Thus, we are requesting that you provide a standing PO that will be valid for several billing cycles (e.g. for at least 18 months). This will minimize future correspondence re: expiring POs.
You can submit the PO info via the PPMS RC Core system. Please use this URL https://ppms.us/harvard-hms/req/?pf=11&project=true and click "RC Billing Form - Required by EXTERNAL Customers with POs".
The PO needs to be made out to the address below:
P.O. Box 4999
Boston, MA 02212
