A few concerns:

- Different businesses have different business rules (for overtime,
part-time employees, vacations, sick time, etc. etc.) which would mean
that any template would require modification, perhaps extensively.

- Access is NOT sufficiently secure that I would want to face the
liability of employees' personal and payroll data getting hacked.

- Payroll involves complex tax and legal issues; a template might or
might not handle these correctly, or at all.

- There are good third-party payroll management services and payroll
software available. It may be worth the extra cost to save possibly
many hours' work building an Access application which might not work
as you wish.

I'd really suggest either getting a commercial service (or commercial
software such as QuickBooks or Peachtree), or hiring a developer with
payroll experience; creating your own Access database may be penny
wise and pound foolish.
