Estimates for a small start in the UK, not guarantees.

What it is

You advise small and medium-sized businesses on one specialist area you already know well, such as operations, pricing, HR, sales processes or finance. Most work is done by video call, phone and written reports from your home office.

Your first three steps

  1. Pick one narrow problem you can solve (for example, pricing for trades firms) and write a one-page description of what you offer
  2. Tell your past colleagues, employers and LinkedIn contacts what you now offer and ask for introductions
  3. Set up as a sole trader with HMRC, draft a simple client agreement and agree your first paid project or trial session
Who pays

Owners of small and medium-sized businesses, charities and start-ups who need expert help but cannot justify a full-time hire.

How it makes money

Day rates, fixed project fees or a monthly retainer for ongoing advice. A few regular retainer clients make income steadier than one-off projects.
