Questions

Frequently asked questions

Is this a full payroll product?

No. This is a free demo tool for planning and product discovery. It does not submit RTI to HMRC or replace recognised payroll software.

Does the tool store payroll or worker data?

No. The demo runs in your browser and does not save the information you enter.

Can I use the exported PDF as a real payslip?

No. The PDF is watermarked as a demo and should not be used as an official payslip or tax record.
