The problem it solves
Payroll is unusual among business software in that "mostly right" is not a category. An error is not a defect to fix next release — it is somebody's rent, and frequently a regulatory matter as well.
How Qeet approaches it
Employee records, leave, attendance and payroll in one place, including the statutory contributions and filings Indian employers are required to get exactly right, on fixed dates, to several different authorities on several different schedules.
Generic international systems handle those obligations poorly or not at all, which is why so many organisations here end up running payroll beside their HR system instead of inside it.
