Supplier Invoices

View the OpenAPI Specification

Supplier invoices are invoices sent to the University by external suppliers, usually in conjunction with Purchase Orders.

Though there is no suppliers resource, the supplierId attribute is comparable to the supplierReferenceId attribute of Supplier Contracts. The reason their names differ is because of the upstream column names they were fetched from. This difference will likely be reconciled in the future.

For invoices the University issues for goods/services it provides to external customers, see Customer Invoices.
