How do pharmaceutical companies charge for invoicing?

Pharmaceutical companies generally have the following steps to collect invoices. First of all, the information such as the amount, content and tax rate of the invoice should be made clear and registered in the system. Secondly, after receiving the customer's payment and checking the bill, the corresponding invoice can be generated. When generating invoices, tax accounting is required, and relevant information is filled in, such as taxpayer identification number, buyer information, commodity details, etc. Finally, the invoice will be sent to the customer by express delivery or electronic transmission to complete the billing and charging process. The whole process needs to pay attention to ensure the authenticity and compliance of invoices, strictly abide by the provisions of the tax law and avoid any problems.
