For a worker paid per piece, the count is the salary. Type each worker's pieces at the end of the shift, keep one rate card, and the month's pay is pieces times rate with nothing typed twice.
The app is called Piece Work. It has three screens.
The sample is Umiya Engineering Works, Ahmedabad, the one demo company on this site.
Piece rate disputes are about the count, not the rate. So the count is typed every day, and each worker can see their own on their phone page.
Attendance, salary and compliance in one place, with 32 apps you open as you need them.
