They can also publish open shifts, keep connected and stay on top of business performance on the go. Employees get more exact schedules, and can quickly and easily requests swaps, suggest unavailability, volunteer for open shifts, request time off and view payroll information, while staying connected with the business, their managers and their colleagues. Managers get out of the back office so they spend more time with their teams and customers, and employees feel happier and more engaged with the business, improving productivity, company culture and employee retention.

Placing orders, completing inventory counts and goods receiving are completed on mobile devices, saving hours of time and eliminating errors caused by re-keying data. Actual Cost of Sales (COS) is easily calculated, and the gap between actual and theoretical is effectively highlighted and can be driven down as actual COS factors in all transactional data, daily sales and other account transfers and inventory movement. The result is better inventory management, ensuring you have sufficient products to meet demand while reducing waste and removing unnecessary administration. Getting started with the Fourth App: The Fourth App requires a Fourth Account to login, your employer needs to have given you access through an activation email and if you have any problems with access you should contact your line manager.

Fourth's advantage is monetization model (free vs paid) and iOS requirement (12.0 vs 16.4). On price, update cadence, ads and in-app purchases there is nothing between them.
