Standard Orders

Each laboratory orders their own supplies and equipment via B2P (Buy-To-Pay). The B2P system is an online eProcurement tool where Harvard purchasers can access over 200 vendors through punchouts and catalogues. B2P combines eProcurement functionality for shopping and selecting items for purchase orders with a supplier portal. 

In order to access B2P, please contact your grant manager who can assist you with obtaining access to B2P. New users must complete a training session prior to using B2P. For additional information and resources, please visit the following website:
