HRMS vs HRIS: what is the difference?
An HRIS (human resources information system) stores the employee record, while an HRMS (human resources management system) runs the day-to-day HR processes on that record, such as attendance, leave and time. In practice the two labels overlap heavily, and many vendors use them for the same product.
Think of the split as noun versus verb. An HRIS answers "who works here, in which role, reporting to whom?" An HRMS answers "who is in today, who is on leave next week, whose hours are still unapproved?"
Older writing drew a hard line between the two, with the HRIS as a database for HR staff and the HRMS as the wider suite. That line has mostly gone. Buy either label today and you'll usually get a record plus some processes. Pay is where definitions still split: some vendors put payroll inside the HRMS, others sell it as a separate product.
So the label tells you little. The module list tells you everything. In a demo, ask to see three screens: the employee profile, a leave request going through approval, and an attendance report for last month.
One more test is worth running. Ask who uses the system every day. If only HR logs in, you're looking at a record. If every employee checks in, requests leave and logs time there, it is running processes.

Questions people ask
Is an HRMS better than an HRIS?
Neither label is better, because vendors use both for similar products. An HRMS usually implies more daily processes, such as attendance and leave. Judge by the modules, not the acronym.
Which does a small company need, an HRIS or an HRMS?
A small company usually needs both jobs: one employee record and the daily processes on it. One system that does both saves a second login and a second copy of every person.
Are HRIS and HRMS the same as HR software?
Yes, in everyday use. HR software is the umbrella term, and HRIS and HRMS are two of the names vendors put on it. The acronym matters less than what each screen actually does.
