It's a 3 year old issue but in case anyone sees it and doesn't know:

invoice = Invoice(client=client, provider=provider, creator=creator)
invoice.number = "MY-INVOICE-23"

You can see all the available parameters for the invoice class in the docs: https://invoicegenerator.readthedocs.io/en/latest/modules.html#InvoiceGenerator.api.Invoice
