Do I need payroll software for a small business?
Yes, if you employ anyone, including yourself as a director. HMRC requires every employer to report pay through Real Time Information (RTI) on or before each payday, and payroll software is the simplest way to do it. Nxsys Payroll files RTI automatically every time you run payroll.

Yes. Nxsys works out the tax, National Insurance and pension contributions for you and checks every pay run before it reaches HMRC. If you get stuck, in-app support and our human support team by chat or phone are included in your £2.00 per employee price.
