The ability of seatriss web app for restaurants, it's very easy use with no need any experience in IT systems or programming language like PHP etc., It has all features that are required by most modern companies who want their customers can make reservations easily without human intervention which saves time as well money. There nothing I dislike about this product but if you looking forward your business requirements then go ahead otherwise there will be many other products available out here so why waste much resources? We have used seattris only because we were already using its competitor service called Open Table at first place however after some months we realized our mistake & switched back from open table to seat trism since now everything working fine even more better than before!
