Для начала участники ООО назначают руководителя и вместе с этим устанавливает капитал и регистрируют юридический адрес,тот адрес, по которому ведомства будут связываться с компанией: присылать запросы, письма, требования и уведомления. Затем необходимо выбрать коды видов деятельности: название и цифровой код для дальнейшего обращения в налоговую службу. До регистрации ООО нужно определиться с системой налогообложения и собрать все учредительные документы. В течение 10 дней после передачи документов в налоговую службу ООО должен быть присвоен ОГРН - основной государственный регистрационный номер. "
