In Taiwan, the government requires business establishments to issue a tax invoice for every transaction. To meet this compliance requirement, you must configure the tax invoice function for your restaurant.

In this article, you’ll learn how to generate and delete invoice numbers, issue a tax invoice for transactions, and reprint past tax invoices.

Generate Invoice Numbers for tax invoice

Before you get Invoice Numbers on the Eats365 mPOS, you must first generate Invoice Numbers on the e-Invoice platform’s portal. After generation, use the mPOS to import Invoice Numbers from the e-Invoice platform for use in transactions.

To import Invoice Numbers into mPOS, follow the steps below:

1. Open the mPOS app. 
2. On the left panel, tap Menu .
   
3. Tap Settings . 
   Tip: You can also access the settings by tapping Settings  at the top right of the mPOS table map screen.
   
4. Navigate to the "Taiwan e-invoice Setting" section.

6. To generate invoice numbers, tap Invoice Number.
   
7. Tap Click to Get 50 Invoice Number to load 50 Invoice Numbers into the mPOS system.
   

Doing this generates 50 Invoice Numbers that you can use for transactions.
