Please note, Xero doesn't guarantee the service of any one advisor

We don’t review advisor listings and we don’t recommend or guarantee the service provided by any one advisor, so make sure you check them out yourself and get comfortable with them yourself.

Xero certification means that some or all team members have completed courses and been assessed by Xero as proficient in the use of the Xero application.

Xero specialisation means that some or all team members have completed several short learning modules to develop skills in that area.

Xero doesn’t assess any individual advisor’s or firm’s proficiency as an accountant, bookkeeper or financial advisor. And Xero certified advisors and advisors with industry or bank specialisations are not employees of Xero.
