It is suggested to look at the network configuration in the parameter settings first, and click Test Connection to see if it can be connected normally. As long as it can be connected normally, you can upload the invoice that has not been uploaded. If it cannot be connected successfully, it may be that the server is maintaining it.

The specific reasons and methods are as follows:

1. When the tax control equipment is just upgraded, the system is very unstable, and the tax authorities always can't keep up with it. Sometimes the invoices are still being submitted after half a day, and the invoices that have not been submitted or are being submitted can't pass the authentication;

2. If the invoice is basically issued and submitted immediately, you can safely close the invoicing software. If it takes too long, it is estimated that there is something wrong with the tax department, so we can only wait. If the other party is not in a hurry to authenticate, leave it alone and close it directly, and the system will automatically save the invoices that have not been submitted or are being submitted;

3. When you open the billing software the next day, you will upload it again. If it is really not good, you will upload it again. Normally, it will show that it has been submitted soon.

4. You can exit the billing system and enter it later. Furthermore, after repairing the invoice, exit the system and enter the viewing state later.

Impact of invoices that have not been uploaded:

1. When the tax control panel is initially issued, the offline limited time and offline invoicing amount have been set accordingly. If the number of invoices that have not been uploaded reaches a certain time and amount, new invoices will not be issued, and the billing point will prompt that the offline invoicing amount and limited time are exceeded after printing;

2. After the invoice has not been uploaded to the buyer, the other party cannot query the invoice information, which will affect the authenticity and authentication;

3. If there are invoices that have not been uploaded during the tax filing period, you will be prompted when copying the newspaper online that there are invoices that have not been uploaded during the tax collection period, and you need to upload the invoices issued before you can report them for summary;

4. When collecting and purchasing new invoices in the tax hall, it is necessary to check the information of invoices that have been opened before. If it is not uploaded, it will be impossible to check the old invoices.

to sum up, whether it's invoicing, voiding or negative red-offset, it needs to be uploaded.
