I work with https://shifton.com/shift-scheduling in one of the large restaurant businesses, so I can tell you how it works in practice. Regarding the automation of shifts - this is one of the strongest points in Shifton. The software really allows you to not only build schedules, but also skillfully take into account such things as vacations, illnesses, overtime, and even employee preferences regarding their work shifts. For example, if someone asks for a day off on a certain day, Shifton can automatically take this into account when creating a new schedule, without requiring manual work. Particularly convenient is the scheduling mechanism, which uses algorithms to optimize schedules. The system can automatically create shifts based on the needs of the business and employee availability. By the way, this is ideal for companies with high staff turnover, because you can easily adapt the system to changes. Regarding integration with other services: Shifton supports quite wide capabilities for connecting to external systems, for example, for accounting of working hours or payroll. If you already have a system for accounting of working hours, this will not be a problem. Integration is done via API, and for most popular services everything is set up quite simply. For example, you can integrate with systems such as Time Doctor, Clockify and others that track employees' working hours.
