The sale of mobile phones belongs to the collection scope of the IRS and belongs to the sale of goods. According to the different ways of issuing invoices, invoices can be divided into machine-made invoices and manual invoices. As the name implies, machine invoicing is a process in which the drawer inputs the relevant data into the computer according to a fixed format, then puts the blank invoice into the needle printer, and the printer prints the invoice after clicking OK. Handwritten invoice means that the drawer now receives the invoice from the tax bureau, and one invoice is generally 25 copies. When the buyer applies for issuing an invoice, the seller takes out the invoice book, finds out a blank invoice that has not been issued, puts a hard voucher separator in the third copy of the invoice, then manually fills in an invoice according to the customer's requirements, and then sends the second copy, that is, the invoice, to the customer. This manual invoice is a handwritten invoice.
