The second invitation, especially at the marriage ceremony, is sent to Lord Vishnu and Maa Lakshmi. In events such as weddings or a newcomer, the blessing of the duo is especially important, because they both bless the couple with love, wealth, balance and more.
It is believed that Lord Vishna convinced that the ritual or the event is protected from the damage, and Maa Lakshmi guarantees that there is no shortage in this event. Maa Lakshmi brings a wealth of money, happiness, love and much more, and thus the second invitation is given.
