Accounting & Tax

Accountant or software — which do you actually need?

Cloud accounting software has made it realistic for very small businesses to handle their own books, but it doesn't replace the judgement an accountant brings once your affairs get even slightly complex. The right setup depends on your structure, not just your size.

Key points
  • Simple sole traders can often manage with software plus an annual review
  • Limited companies almost always need an accountant for statutory filings
  • A hybrid of software plus quarterly accountant review suits most growing businesses
  • Persistent missed deadlines are a clear signal to get help

When software alone is enough

A sole trader with simple income, no VAT registration and no staff can often manage with software plus an annual check before Self Assessment. The software handles the record-keeping; you still want a second pair of eyes once a year.

When you need an accountant too

Limited companies have statutory accounts, corporation tax and Companies House filings that carry real penalties if done wrong. VAT-registered and employing businesses add quarterly returns and payroll compliance that most owners don't have time to master properly.

What a good hybrid setup looks like

Most growing UK businesses land on cloud software for day-to-day bookkeeping, with an accountant reviewing quarterly and handling the statutory filings. This keeps monthly fees down while still covering the parts that carry legal risk.

Signs you've outgrown DIY

Missed VAT deadlines, uncertainty about what's tax-deductible, or spending more than a couple of hours a month untangling the books are all signs it's time to bring in professional help, even part-time.
