Computer invoices can be divided into actual uploading and limited uploading. "Real-time upload" means that users upload the invoice information to the tax authorities immediately after issuing invoices, and users can only issue invoices online. If the data can't be transmitted due to lack of Internet access or poor network connection, and the user can't continue to issue invoices, it will be automatically uploaded in real time. After filling in the invoice content, the user will automatically upload the invoice content to the tax authorities by clicking the "Invoice Print" software.

"Time-limited upload" can issue invoices within the time limit stipulated by the tax authorities. If the time limit is exceeded, the previously issued invoice must be "uploaded" first. After the upload is successful, the software will automatically lift the restrictions and users can continue to issue invoices. You can also consult the local tax authorities for details.
