The conclusion follows from the clarification of Economic Development. Office states: legislation does not set the number of times you can change the terms of the contract in the case where the quantity of goods (volume of works or services) is increased or reduced by no more than 10%.
The new contract price at the same time should not differ by more than 10% of the price, which was established as a result of the definition of the supplier (contractor, executor).
Earlier the Ministry of Economic Development noted: Law N 44-FL does not provide, it is permissible to repeatedly increase or decrease, in particular, quantity, volume of work or services under the same contract.Document: Letter of the Russian Ministry of Economic Development from 20.06.2016 N OG-D28-8176
