Procure to Pay (P2P)

– Invoice Mitie

Coupa is Mitie’s new Purchase to Pay (P2P) system and changes the way we do business with our suppliers.

Depending on the volume and frequency of transactions there are multiple ways you can invoice via Coupa, you can either choose

a) Coupa Supplier Portal (CSP) – An email invitation will need to be received to register on the CSP. We recommend using the CSP to: Manage your company information; Configure your company PO transmission preferences; View all POs; and Create & Transmit electronic invoices & credit notes. Benefits of using the CSP are a faster invoice-to-pay process with convenient, real-time visibility of invoice/payment status


b) Supplier Actionable Notifications (SAN) – It allows you to act on POs directly from email notifications for POs created in Coupa, having the options to acknowledge, create an invoice from, or add a comment to a PO, or create a CSP account if they want to take advantage of the benefits of working with their customers through the CSP.

Tax Exempt or under the CIS scheme?

If you are a Supplier who is Tax Exempt or registered under the CIS scheme, please refer to the Quick reference guide on how to manage Invoices.

* Note: Suppliers under the Construction Industry Scheme (CIS) please refer to this Guide.

Disputed Invoices?

If your invoices are displaying a Disputed status, please refer to this Quick reference guide on how to resolve this,

*Note: Mitie workwise email address will not accept emails with Coupa PO related invoices and they will be a Return to vendor process.
