The method of reading invoices in the billing system is as follows:

1. After purchasing a new invoice, log in to the VAT invoice fiscal invoicing (Golden Tax Edition) software.

2. In the VAT invoice tax-controlled invoicing (Golden Tax Edition) software, click Invoice Collecting Management-Online Ticket Collecting Management-Invoice Collecting.

3. After coming in, select the time period for purchasing invoices, and then click Query-Invoice Download.

4. When downloading the invoice, you no longer need to read the invoice separately. You can directly click "Fill in Invoice" to issue an invoice, so that the invoice will be automatically read.
