If you are an iPay vendor, you must reference either a Purchase Order (PO) or a user ID on the face of your invoice. Any paper invoice (iPay) received without either of these references will be auto rejected. If you are an epayables vendor, you must submit your invoice against either a Purchase Order (PO) or the Contract Outline Agreement (OLA) number. Note that it is only employment agencies who submit their invoice against a Contract OLA.

If you are an iPay client, please mail your paper invoice to the Bill To name and address as stated on the Purchase Order. Please note that the company has different U.K. legal entities, so it is imperative that you refer to the PO for the correct Bill To company name for your invoice.


If you are an ePayables client, please submit your invoices electronically through our ePayables system. If you or your company have not been trained to submit using this system, then you or your company are an iPay client. Please remember that an ePayables invoice submission must reference either a PO number or for employment agencies only, an OLA number in 46000xxxxx format. For those submitting against an OLA, a Reviewer ID must be included along with cost coding if this has been provided.
