**"When will I receive it?"**
For online payments, the invoice details will be sent to your provided email address within 1 hour after payment.
For cash on delivery (COD), the invoice details will be sent to your provided email address the day after pickup.
If you choose a paper invoice, it will be sent along with the product, and you do not need to provide a separate address for the invoice.
**"How can I check my electronic invoice details?"**
Please check the email address you provided when placing the order.
If you chose to use a mobile barcode or Natural Person Certificate barcode as the electronic invoice carrier, please visit the Ministry of Finance's Electronic Invoice Integration Service Platform to check your invoice by using the "Invoice Carrier Query" feature.
**"How will I know if I won a prize and how can I claim it?"**
Please check the winning numbers published by the Ministry of Finance for the **non-requested original invoices / non-donated / non-invalidated / non-registered invoices** by using the computer for prize matching. If your invoice is a winning one, **This is us** will send you a prize notification via email. Winners should go to a **FamilyMart** store to claim the prize. Details about the prize redemption process will be provided in the notification.
If you have chosen to donate or have used a universal carrier for the winning invoice, the Ministry of Finance will notify you separately.
**"Can I change or reissue the invoice type after it's been issued?"**
In accordance with the National Taxation Bureau's policy, once an invoice is issued, it cannot be changed or reissued. Please confirm whether you need a **two-copy electronic invoice** (for personal consumption) or a **three-copy invoice** (for company reimbursement, requiring the company’s tax ID) at the time of signing the contract. If you have chosen a carrier or donation option, paper invoices cannot be provided.
**"Can I request multiple invoices or specify the date, item, and amount on the invoice?"**
**This is us** uses an automated system for issuing invoices, so it is not possible to issue multiple invoices or specify different items, amounts, or dates.
**"What should I do if the tax ID is incorrect on the three-copy invoice?"**
If the three-copy invoice has incorrect information and needs to be changed, please contact our customer service hotline or LINE within three days of receiving the electronic invoice notification (no later than the 3rd of the following month), and provide the **correct name and tax ID**. This will help us void the old invoice and reissue a new one (processing time is about 7 business days).
**"What should I do if I lose a paper invoice?"**
For customers who choose paper invoices, the original paper invoice will be sent to the address provided when placing the order. Each invoice is issued only once, and no reissuance will be made if it is lost.
**"If I need to return or exchange goods, do I need to send back the paper invoice?"**
If a **two-copy invoice** requires a "sales return or credit note," there is no need to return the invoice. When the customer requests a paper invoice, they agree that **This is us** will handle the sales return or credit note on their behalf to speed up the refund process. At that time, **This is us** will directly issue a credit note and upload it to the Ministry of Finance's Electronic Invoice Integration Service Platform.
If it is a **three-copy invoice**, after **This is us** issues the credit note, a notification email will be sent. Please download and print the four-copy credit note, stamp the invoice, and send the first and second copies by registered mail to **This is us Accounting Department, 313 Qianjia Road, East District, Hsinchu City** for processing.
