With a PunchOut order, the buy­er starts direct­ly in the e‑procurement sys­tem (e.g., SAP Ariba) and opens your con­nec­ted B2B shop.
There, they sel­ect pro­ducts and add them to the shop­ping cart. This is then auto­ma­ti­cal­ly trans­fer­red back to the cus­to­mer’s sys­tem, whe­re the order is com­ple­ted as usual.
This means that the enti­re pro­cess is digi­tal and the­re is no need to enter data twice.
