We receive invoices and pay vendors using the Invoice Processing Platform (IPP).
The Prompt Payment Act ensures we pay vendors in a timely manner—we must pay late interest penalties if we pay vendors after the payment due date.
Below is an explanation of the different payment terms. These terms define how we pay vendor invoices.
| Term | Definition |
| ADV N/30 Prompt Pay | Paid 30 days from either the start of service period/receipt of goods or the invoice log date, whichever is later. |
| ADV Immediate Prompt Pay | Paid immediately following the start of the service period. |
| ADV Due Upon Receipt | Paid immediately on receipt of invoice, but no more than 30 days before the beginning of the service period/scheduled delivery date (unless noted otherwise in the contract). |
| Net 30 | Paid 30 days from either the end of service period/receipt of goods or the invoice log date, whichever is later. |
| Due Upon Receipt | Paid immediately after the end of the service period/receipt of goods. Interest is added to the amount due if we don't receive payment within 30 days. |
| Immediate Prompt Pay | Paid immediately after the end of the service period/receipt of goods. Interest is added to the amount due if we don't receive payment within 30 days. |
