Invoicing and Payment
Shirley Contracting and its associated companies use the Coupa Supplier Portal (Coupa) to manage transactions with its suppliers. The portal improves the accuracy and speed of the payment process and gives suppliers instant access to payment information. Since Shirley Contracting is a subsidiary of Clark Construction Group, the portal and communication from the portal will be from Clark.
Coupa allows you to:
- Submit invoices electronically
- Review invoice status
- Receive notifications when invoices are paid
- Resolve invoicing disputes
- View purchase orders
- Send shipping/tracking information for orders
- Grant other employees access and configure their permissions
- Coupa is the most efficient way to get your invoice paid. However, you can also submit your invoices by cXML transmission. This option lets you send invoice information through an Invoice Detail Request in cXML and post the file directly to Coupa via an HTTP post.
Shirley has a “No PO, No Pay” Policy in effect. Please click here for the full Company Invoicing Standards. Failure to meet these invoicing requirements will cause payment delays and may result in your invoice being rejected.
