What it is
A package service that records sales and expenses, raises and chases invoices, reconciles bank accounts and handles routine admin, usually using cloud accounting software.
Your first three steps
- Take a bookkeeping course or software certification if you don't already have recent experience
- Set up as a sole trader, get insurance and draft a clear service package with fixed monthly prices
- Approach local tradespeople, accountants and business groups who may refer clients who need ongoing help
Who pays
Small trades, shops, therapists and other owner-managed businesses that want one person to keep their paperwork in order.
How it makes money
Fixed monthly fee based on the number of transactions and admin hours, plus extra for catch-up work or one-off projects.
Skills that help
- Comfortable with numbers and accuracy
- Cloud accounting software such as Xero, QuickBooks or FreeAgent
- Good record keeping
- Explaining things clearly to non-experts
Watch out for
- Bookkeeping is not regulated in the same way as accountancy, but check whether you need anti-money laundering registration for the services you offer
- Professional indemnity insurance is worth checking
- Don't give tax advice unless you are properly qualified
- Register with the ICO if you process personal data, check whether this applies
- Deadlines such as VAT returns are the client's legal responsibility, so agree in writing who does what

Questions people ask
How much does it cost to start a bookkeeping business?
Startup costs are typically around £300 to £2,000, depending on your software subscriptions, equipment, training and insurance. These are estimates, so check what cloud accounting tools you need and whether professional indemnity insurance is worth having.
How much can a freelance bookkeeper earn?
Monthly revenue is typically around £800 to £4,000, depending on how many clients you take on and your fixed monthly fees. Your own hours and the complexity of each client's books will affect where you land in that range.
What rules should I check before offering bookkeeping?
Check whether you need anti-money laundering registration for the services you offer, and whether you must register with the ICO if you process personal data. Don't give tax advice unless properly qualified, and agree in writing who handles deadlines such as VAT returns.
