I have explained Russian Armed Forces for what state procurements the payment term established on 44-FZ for small business works

The term of payment of contracts with small business entities and socially oriented non-profit organizations provided by the Law N 44-FZ is applied when contracts are concluded following the results of purchase only among these persons. Procurement documentation has to limit participation in purchase of all, except SMP and COHKO.
Inferior courts have considered that this term is applied under all contracts concluded with SMP and COHKO. The Supreme Court hasn't agreed with such approach.
Please note that tells Russian Armed Forces about the 30-day term of payment which was applied until the end of April. Since May 1 for the contracts concluded with SMP and COHKO, the specified term shouldn't exceed 15 working days from the date of signing by the customer of the document on acceptance. Other contracts should be paid no more than 30 days in time.
