Yes, you can sell tickets by tables using the ticket type "Table".
Table ticket types allow you to set the number of seats available for each table and each seat on the table sold will be given a ticket. Seats can only be sold together for example a table size of five seats must all be purchased at the same time.
By giving each person at the table their own ticket, you can also request extra guest informantion for each seat at the table. You can view more about requesting extra guest information
here. It also helps you keep track of your event capacity as each seat is counted as one ticket.
Table ticket types work with all other functionality on OutSavvy including the Waiting List and Ticket Resell.
