The government has defined additional conditions under which in the notice on implementation of purchase and (or) the draft contract the customer has the right not to establish the requirement to provide providing the contract. New rules almost don't differ from former.
The customer can not demand providing the contract, for example, if he carries out electronic auction among small business entities, and also socially oriented non-profit organizations. At the same time payment of advance payment shouldn't be provided in the draft contract.
