Is it possible to use an account agreement instead of a regular agreement with acts and other crap in the Russian Federation?

Question

Freelance

Now I work with two customers not from the Russian Federation and use the "agreement-account" for making payments, before that in the Russian Federation they always made these stupid Contract -> TK -> Act, etc. for any sneeze. I understand that if I'm doing a big project, it's in my own interests to draw up a clear statement of work and work on it. But sometimes there is small work for 15-20 thousand in 1-2 days, and then even if there is some kind of template contract, you will have to mess around for a couple of hours, plus all these transfers back and forth. Will the tax invoice pass in this case when the declaration is closed?

Answer 1

This is individual for each tax.
For example, I worked on the DSA, being an individual entrepreneur, and this did not cause problems for a client from Rostov-on-Don, but a client from Moscow considered this piece of paper a flimsy letter.
Now I am self-employed at the NPA and everyone takes the DSA without any problems.
