I am self-employed, and my business scope is: photo painting, advertising design and exhibition. How should I write the invoice? Can I write advertising fees or promotional materials?

First of all, it depends on what tickets you have: service industry (local tax) and advertising industry (national tax), and also depends on your stamped name.

Service industry: the cost of text production is basically summarized, depending on the requirements of customers. Photo production costs, exhibition shelf production costs and so on. Your seal can be production center, studio, printing department and so on.

Advertising: You can only write the advertising fee-your stamp should be the name of the advertising company.

It's best not to write promotional materials, so you need to print pages of tickets. You can write a single page and change the production fee.

Now it's all mechanical, and some of them are frozen hotels. The chapters are different and strict, but they are probably the same.
