Purchase to Pay


Welcome to the supplier support page for Knight Square’s Purchase to Pay (P2P) system, powered by Coupa. This page will provide you with all of the necessary training materials, guides and FAQs that you will need to use the new system and processes. Please note that we are currently in the process of rebranding with Knight Square being the new name for the Peverel Group. As such we are working through a period of transition which will mean that some of the training documentation as well as the system itself may reference Peverel.

Our new P2P system and processes will make the Knight Square group of companies , as customers, much easier to work with.

The following are just some of the benefits that you, as one of our suppliers, will enjoy:

  • All of your orders will be received electronically
  • The ability to invoice us electronically, by turning the purchase order into an invoice (PO flip)
  • The ability to be able to view when invoices have been approved for payment
  • A very transparent and seamless P2P process which will help you better financially manage your business
