Each application can upload up to 8 attachments. If the number of attachments exceeds, the following methods can be adopted:

1. Take multiple invoices with one picture, and the invoices overlap, so as to ensure that the invoice code and number of each invoice are clear.

2. Make it into a PDF file format and upload it. Choose a shorter issuance cycle and submit applications in multiple times to reduce the number of attachments for each application. This is how the tax bureau uploaded many pictures.
