What is payroll implementation?

Payroll implementation is setting up new payroll software or services. It includes configuring tax codes, pension schemes, pay elements, and schedules; migrating employee data and historical records; testing thoroughly; and training users before the first live payroll run.

How long does payroll implementation take?

Payroll implementation typically takes 4-8 weeks for straightforward setups. Complex implementations with multiple pay frequencies, pension schemes, or integrations may take 8-12 weeks. Proper testing before the first live run is essential.

What are the risks of DIY payroll implementation?

Risks include incorrect tax calculations, pension contribution errors, pay frequency mistakes, and missing key deadlines. Payroll errors affect employee trust and can result in HMRC penalties. Professional implementation reduces these risks significantly.

Can we implement payroll mid-year?

Yes, mid-year payroll implementation is common. The key is accurate transfer of year-to-date figures—tax paid, NI contributions, pension contributions, and other cumulative data. Our services ensure this critical data transfers correctly.

Does Factorial include payroll?
