Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
For a missing fa piao or tax invoice:
- Sign in to Order history with the same Microsoft account used for the purchase.
- Find the order and select Order detail.
- Check whether Tax invoice is available there.
- Tax invoices are not available in real time and typically appear within 48 hours up to 5 days.
Since the fa piao was requested on 4 Oct and still has not appeared, this likely needs Billing Support to review the order.
Use Microsoft Support to contact them:
- Go to Contact Microsoft Support.
- Select the product related to the purchase.
- Use Get Help or Contact Support for billing assistance.
