1. Invoicing system failure or maintenance: the invoicing system may be undergoing maintenance or trouble-shooting, resulting in the inability of normal invoicing. At this time, you can consult the customer service staff of the invoicing service platform to understand the specific progress of invoicing and the expected time of resolution.
2. Incorrectly filled in information such as invoice header, amount, content, etc.: If the invoice header, amount, content, etc. are incorrectly filled in, you need to make corrections and check them. This may lead to delay in invoicing. In this case, you should contact the customer service staff of the invoicing service platform in time in order to correct the relevant information and get the correct invoice.
3. Invoices take longer to review or need to be double-checked: In some special cases, invoices may take longer to review or need to be double-checked, which may lead to delays in invoicing. In this case, you need to wait patiently and pay attention to the relevant notifications and updates pushed by the invoicing platform. Once the review is approved, you will receive the result of e-invoicing.
In addition, there may be other unknown factors that prevent normal invoicing. If the above methods do not solve the problem, we recommend that you contact the customer service staff of the invoicing service platform for further assistance.
