status	string	Current state of an invoice, one of: `open` - Invoice is no longer a draft. It has been processed and/or sent to the customer. In this state, it will impact the ledger. It also has no payments made against it (amountDue == totalAmount). `partiallyPaid` - The balance paid against the invoice is positive, but less than the total invoice amount (0 < amountDue < totalAmount). `paid` - Invoice is paid in full. This includes if the invoice has been credited or overpaid. (amountDue == 0). `void` - An invoice can become void by being deleted, refunded, written off, or cancelled. A voided invoice may still be partially paid and so all outstanding amounts on voided invoices are removed from the accounts receivable account. `draft` - Invoice is yet to be authorized and sent to the customer, and will not be used in any reports. It may contain incomplete line items. `unknown` - Unable to recognize the status of the invoice. This can be due to missing values in the accounting service provider or unavailable in the data we received.
