A customer's invoice.

The Invoice is the central mechanic upon which the entire WHMCS billing process is built upon. Orders request Services based on Products, which are turned into Invoices to handle payments. Future payments are then made against invoices until such time as the Client makes a CancellationRequest for the Product.

Each Invoice is attached to a specific clientId, and contains one or more invoice line items which actually define the products and prices paid on the invoice.

Tax Rules are configured in Setup -> Payments -> Tax Rules.

Multiple tax rules from each level may be valid for an Invoice, but only the lowest-numbered-ID tax rule will actually be applied to the Invoice.

Note that $id and $invoiceNumber are completely separate entities. The $id is used internally to track the invoice, while the $invoiceNumber is provided to the client and may be used for other tracking purposes; for example, VAT tax compliance.
