Is it okay to write the name of the billing account for the project appropriation to Party B?

Of course.

In the field of construction, if the money collected by taxpayers for providing construction services is advance payment, it is generally issued in the name of advance payment or advance payment, and there is no dispute; If it is a project progress payment, you can choose more names. Such as project payment, project progress payment, labor cost, subcontracting payment, construction service fee, project service fee, installation fee, installation fee, etc. As long as you choose the correct code and the displayed code is abbreviated as construction service, these invoices are all compliant.

The current policy does not clearly specify the name of the invoice. Generally speaking, it is paid according to the nature of the expense items, commodity names and agreed habits, such as meals, accommodation fees, consulting fees, computers, commercial concrete and so on. The product name itself is not the decisive factor of invoice compliance.
