This question is in the context of selling products internationally. How should I date invoices and invoice payment dates?
Assuming we have an online shop based in Sydney, Australia. Should we always date the invoices and payment dates using our local time?
If a customer in Los Angeles purchases a product from us on
15 November 2011 10:00 AM Sydney time, their local time is
14 November 2011 3:00 PM. If we send them an automated invoice dated at our local time once the order is placed, then they would have received an invoice from the "future".
Is this acceptable practice? How would you date your invoices?
