1. Confirm whether the tax bureau to which each invoice belongs has successfully issued your golden tax receipt information (it can be issued from 1 to 15 every month, except holidays).
2. If it has been published successfully, you can try to calibrate the clock in the billing software (click the summary processing menu-Golden Tax Equipment Management-Golden Tax Number Plate Clock Calibration for manual calibration).
3. If you can't solve your problem in steps 1 and 2, you can try to re-insert the golden tax plate into the computer, or re-calibrate the clock after restarting the computer. If the above methods fail to solve your problem, it is recommended that you contact the aerospace information service personnel or the golden tax board service unit for consultation.
I hope the above information can help you solve the problem. Please feel free to let me know if you have any other questions.
