HR and Payroll Software Glossary and Key Terms
The HR and payroll vocabulary in plain words, written for buyers. Each term defined, and where it maps to cost or a specific tier, we say so.
The HR and payroll vocabulary, in plain words
HR and payroll buying gets harder when vendors and reviewers use the same words to mean different things, and when a single term, like PEO or full service, quietly decides whether your bill is a flat per employee fee or a percentage of payroll. This glossary defines the terms that actually affect your decision, written for a buyer rather than a vendor. Where a term maps to cost or to a specific tier, we say so.
Use it alongside our how to choose and pricing guides, where these terms do the real work of separating tools.
Glossary of HR and payroll terms that matter
An HRIS, or human resources information system, is the central record of your people, jobs, pay rates, and documents. HRMS adds broader management features such as performance and learning. Many modern tools fold the HRIS, payroll, and benefits into one platform.
A single cycle of calculating and paying wages, including deductions and taxes, for one pay period. How easily you can run, preview, and correct a run is the daily test of any payroll tool.
Payroll where the provider also files and pays your federal, state, and local payroll taxes on your behalf, rather than only producing the numbers. It is the line that separates a true payroll service from a calculator, and it shapes the price.
A professional employer organization shares employer responsibilities with you under a joint model, handling payroll, benefits, and compliance while you stay the day to day employer. It usually needs you to have a legal entity, so it suits domestic teams. Priced per employee or as a percentage of payroll.
An employer of record becomes the legal employer on paper in a given country, which lets you hire abroad without your own entity there. The provider owns contracts, statutory contributions, and severance. Per worker fees run well above a PEO, reflecting that infrastructure.
The tools to offer and manage health insurance, retirement, and other benefits, including enrollment and payroll deductions. Whether you can bring your own broker or must use the vendor's plans is a common point of lock in.
The structured flow of bringing a new hire into the system, collecting tax and bank details and documents, and the reverse when someone leaves. Strong onboarding is where an HR platform earns its keep beyond payroll.
Tracking hours worked and managing paid time off and leave balances. Often a paid add on or a higher tier feature, and essential if you employ hourly staff whose hours feed each payroll run.
Paying independent contractors, often in other countries, with the right forms and currencies. Many vendors price contractor payments separately from employee payroll, so count both when you compare.
The interval over which wages are earned and the calendar on which they are paid, such as weekly, biweekly, semimonthly, or monthly. Some plans cap how many pay schedules or off cycle runs you can use without extra cost.
The federal payroll tax under the Federal Insurance Contributions Act that funds Social Security and Medicare. It is split between employee and employer, with Social Security capped at an annual wage base the government sets each year and Medicare uncapped. As of June 2026, the Social Security rate is 6.2 percent each side and Medicare 1.45 percent each side.
Unemployment taxes paid by the employer, federal under FUTA and state under SUTA. As of June 2026, the FUTA rate is 6.0 percent on the first 7,000 dollars of each employee's wages, with a credit of up to 5.4 percent for paying SUTA on time. A full service payroll tool files and pays these for you.
A court ordered deduction taken from an employee's pay before it reaches them, for things like child support, defaulted loans, or a tax levy. Whether the tool automates the calculation and remittance, or leaves it to you, matters for compliance.
The standard HR and payroll pricing model, often shown as PEPM: a monthly base fee plus a charge for each active employee. Total cost is base plus employees times the per person rate, plus add ons. Active contractors may count too.
A one time charge for setup, data migration, and training, separate from the subscription. Common on enterprise platforms and larger PEO deals; many small business tools waive it. As of June 2026, confirm with the vendor, since it is often negotiable.
Where the vocabulary meets the bill
A general map of which HR and payroll concepts unlock at which class of plan as of June 2026. Exact gating differs by vendor; check the vendor for current packaging and pricing.
HRIS stands for human resources information system: the central record of your people, jobs, pay, and documents. Many modern HR and payroll tools combine the HRIS with payroll, benefits, and time tracking in one platform.
A PEO shares employer responsibilities with you under a joint model and usually needs you to have your own legal entity, so it suits domestic teams. An EOR becomes the legal employer on paper, which lets you hire in countries where you have no entity. EOR fees per worker are typically much higher than PEO fees. Check the vendor for current pricing.
Full service tax filing, benefits administration, contractor and global payroll, time and attendance, and PEO or EOR service are the features most often gated to higher tiers or priced as add ons. Knowing which you truly need tells you the tier to budget for. Check the vendor for current packaging.
