A time clock is bought as a device and lives as a control. The record it produces will be read by whoever runs payroll every week, by a manager in a disagreement, and occasionally by somebody outside the business who is entitled to ask. Choosing on how it feels to punch in misses two of those three audiences.
Three properties that make hours evidence
The original punch is preserved, changes are attributed to a named person with a time, and the person whose hours they are cannot silently alter them. Products vary most on the third and almost never lead with it. Ask what a supervisor can do to a subordinate's week and whether the subordinate can see that it happened.
Specify for the weekly reader
Whoever runs payroll wants totals that need no arithmetic and exceptions listed in one place. Ask to see the weekly processing screen rather than the dashboard, because the dashboard is built for the buyer and the weekly screen is built for the person who will use it fifty times a year.
Specify for the outside reader
Records may have to be produced years later in a form somebody else finds credible. A product that exports a picture of a screen is not that; one that exports structured history with timestamps and edit attribution is. Retention duties are set by employment and tax rules rather than by a vendor default, so check the setting and change it.
Questions people ask about time clock for business
How long must we keep the records?
Longer than most vendor defaults, and the duty is yours. Check the retention setting or schedule your own export.
Does it need to connect to payroll?
Not strictly, and if it does not, somebody retypes hours every period. That retyping is both a cost and where errors enter.
Is one clock enough for two sites?
Only if nobody works at both, which they do. Either put a device at each entrance or choose a product handling several sites against one record.
