Then ask your local tax software staff to install billing software for your tax-controlled computer (we have space tax here, so we buy a golden tax plate and plug it into the computer).
After you install it, log in to the billing software, set the administrator, company name, commodity name, select the tax rate, and you can invoice.
Before invoicing, it is recommended to print a blank sheet of paper, and adjust the printer settings according to the invoice, so that the position of good words can be moved to the left or right.
When invoicing, look at the invoice number issued by the system and put in the paper invoice with the same number, which can't be wrong.
Pay attention to whether the amount includes tax when invoicing.
Stamp the invoice special seal after printing.
