Accounting costs vary enormously. For accounting software, you could pay around £20-30 a month as a sole trader but this can increase to several £100 as your business expands. Similarly, an accountant might charge a monthly fee as low as £60 or as high as £1000+ depending on your size and needs. A bookkeeper can look after your day-to-day accounts which may be cheaper, but you’ll still need an accountant to prepare year-end accounts.
