How invoices are paid and saved

This page covers how the game pays and saves the invoices a mod sends.

Things to know

• The player pays an invoice by putting the bill into a payment machine. The game has no other way to pay one: no bank page, computer or phone pays an invoice. The game checks the money, takes it from the player’s wallet, runs the invoice’s follow-up action, and removes the invoice from the open list. (The only path is InvoicePaymentMachine.Select, which calls InvoiceController.PayInvoice.)
• The open invoices are saved with the rest of the game. The bill item in the player’s mail or bag is a separate thing that carries the same data. Cancelling or paying an invoice does not remove that item from the mailbox or inventory. (InvoiceController is a SavableScript, and its public invoices list is saved with the global save. The item is a mail item that carries the same ItemInvoiceData object.)
