Alongside traditional accounting, the company offers audit and assurance, corporate finance, tax planning, outsourced finance support, payroll, forensic accounting, and business growth services. It’s particularly appealing for companies looking for more of an advisory approach.

Pros:

  • Comprehensive accounting, tax, audit, and business advisory services.

MHA is one of the UK’s largest independent accountancy groups, providing audit, tax, consulting, outsourced accounting, and advisory services to companies ranging from SMEs to multinationals. As part of an international accounting network, the firm combines national resources with local expertise.

This makes it well-suited to businesses with ambitious growth plans or overseas interests. But, the service here can feel less boutique than some of its alternatives, leading to a less personalised service.

  • Broad range of specialist tax services.
  • Experienced sector specialists in several industries.

As recommended as each of these can be, many business owners could still be a little confused, especially when it’s their first time using these kinds of firms. They mightn’t be sure of what they should expect.

Thankfully, this doesn’t need to be nearly as complicated as it could seem. While there’ll be differences from firm to firm, entrepreneurs can typically expect similar services, like:
