How to escape from VAT with services

This text is more a question than an answer. And even more warning.

We are an IT company, we are developing software, there are several legal entities on the UPDF, there are with VAT. Our customers are in the West, so the question of VAT did not arise and we worked and work with them in different legal entities, depending on the need for production.

Now we are carrying out a large (for us) software development project in Russia. And it had to be carried out through a legal entity with VAT.
And we do not have suppliers with VAT, computers, furniture bought long ago, rent without VAT, costs only salary - where to put it? And now also the end of the year.
But most of all, the accountant killed, saying that we can credit the VAT only within a quarter. That is, during the year we had some expenses with VAT, but now we can’t accept them. Cool invented, yes?

There is a wild desire to buy something unnecessary with VAT, and then sell it next year, and so on in a circle, but this is not our profile. Maybe there are some other options for which we are developers, so our state has something ... For the Merikos, it means it is more profitable for us to write than for ours.
