What it is

You run payroll for small businesses using payroll software: calculating pay, tax, National Insurance, pensions and payslips, and submitting reports to HMRC on time.

Your first three steps

  1. Take a recognised payroll course or brush up your knowledge, and compare payroll software designed for bureaus
  2. Set up as a sole trader, then price your service per employee per pay run after checking what local bureaus charge
  3. Approach local accountants, bookkeepers and small employers, and offer to take on one or two clients to start
Who pays

Small employers such as cafés, tradespeople, care providers, shops and nurseries, plus sole traders who have taken on their first employee.

How it makes money

A monthly fee per client, or a fee per employee per pay run, with extras for pension submissions, year-end work and new starter set-up.

  • Hard deadlines for HMRC submissions and pension contributions, so plan cover for holidays and illness
  • Agree in writing who is responsible for supplying correct information and for any penalties
