Switching is easy

Whatever your business goals or company size, we make switching accountants as easy as three simple steps.
  • 1
    Contact our office to arrange an exploratory call or meeting

    We’ll meet with you to discuss your accounting needs and together choose the package that best suits you.

  • 2
    Complete our simple online switcher programme

    If you’re happy to make the switch, we’ll ask you to sign a standard letter informing your current accountant.

  • 3
    Focus on running your business and let us take care of the rest

    We will then liaise with the accountant to retrieve all your past files and bring your accounts up to date.
