3.1.36 Invoice ID

An Invoice ID is an invoice-issuer-assigned identifier for an invoice encapsulating charges in the corresponding billing period for a given billing account. Invoices are commonly used for scenarios like tracking billing transactions, facilitating payment processes and for performing invoice reconciliation between charges and billing periods.

InvoiceId adheres to the following requirements:

• InvoiceId is RECOMMENDED to be present in a Cost and Usage FOCUS dataset.
• InvoiceId MUST be of type String.
• InvoiceId MUST conform to StringHandling requirements.
• The sum of BilledCost for a given InvoiceId MUST match the sum of the payable amount provided in the corresponding invoice with the same id generated by the InvoiceIssuerName.
• InvoiceId nullability is defined as follows:
  • InvoiceId MUST be null when the charge is not associated either with an invoice or with a pre-generated provisional invoice.
  • InvoiceId MUST NOT be null when the charge is associated with either an issued invoice or a pre-generated provisional invoice.
• InvoiceId MAY be generated prior to an invoice being issued.
• InvoiceId MUST be associated with the related charge and BillingAccountId when a pre-generated invoice or provisional invoice exists.
