How to submit reports of a non-operating LLC on the simplified tax system without spending a lot of money and time?

Question

Electronic accounting

Is there a service for submitting financial statements for an LLC on the simplified tax system that is temporarily not operating with adequate prices?

I opened an LLC for a project, the project was completed, now there is no activity. There are no employees except for the general director (on unpaid leave). I hand over financial statements through Kontur.Elba. She has a zero reporting promotion for an LLC on the simplified tax system. But even taking into account the discount, the price is still horsey, 11,900 instead of 18,000. And the promotion is in fact suitable for organizations who either do not have a current account, or who have a current account for free and no interest is charged on the balance.
