Yes, receivables and payments are automatically created for all orders that were received before the plugin was installed. Receivables are created if an invoice has been created for this order in the system. Payments are always created when the order has the payment status Fully paid. Please note, however, that for old orders it cannot be guaranteed that every business transaction is mapped correctly. When exporting an old order, only what is currently visible in the Line Items tab can be exported. This is not necessarily the content of the invoice, as this data is unfortunately not available for evaluation.
