Hangzhou Metro app shows that enterprise users can't invoice because there is a problem with background export. You can follow these steps:

1. Download the "Hangzhou Metro" APP.

2. Click "My" and "Bus Card" to bind Alipay account.

3. Click "Electronic Invoice" (it takes about half an hour to bind for the first time, and records need to be synchronized in the background).

4. Fill in the invoice information as required, and it will be sent to the designated mailbox.

5. In some special circumstances, such as incomplete travel records and reimbursement for non-Alipay consumption, you can call this number for manual service consultation.
