What it is

A small practice preparing year-end accounts, Self Assessment returns, company tax returns and VAT returns, often with bookkeeping and payroll help alongside. Most work and client contact is done online.

Your first three steps

  1. Check which accountancy qualification or professional body membership suits you and what your future clients will expect
  2. Set up cloud accounting software, professional indemnity insurance and a simple engagement letter and fee list
  3. Tell your network, local business groups and online communities, and offer a free chat to your first few clients
Who pays

Sole traders, landlords, contractors and small limited companies who want someone to handle their accounts and tax.

How it makes money

Fixed annual or monthly fees per client, with extra charges for one-off jobs such as company set-up or tax advice. Clients tend to stay year after year.
