How to organize the operational activities of an online advertising agency?

Question

Electronic accounting

Good afternoon!
I have an individual entrepreneur working under the simplified tax system without a current account in the field of sales.
I want to add additional activities to my sole proprietorship such as website development / online advertising and work with clients under contracts.
As far as I am poorly versed in such issues, the following points are not clear to me:
1. How to report to the tax office, how will the tax be calculated?
2. How to make settlements with clients? Do you need an account for this? Is it possible without a current account for cash
?
4. How can I then work under contracts / settle accounts with clients / pay taxes / report to the tax office?
I would be grateful if someone could advise me!

Answer 1

Hire an accountant
==
1) There is such a thing as a “book of income and expenses” and a “USN declaration”
2) I don’t know how for individual entrepreneurs, but it will be much more convenient for your legal entities to work with non-cash, unless of course you don’t want to blackmail. white legal entities do not like cash very much.

Answer 2

according to p2 they can fuck for the cashier, usually if the individual entrepreneur is all non-cash
