Do I need a an accountant near me?

Meeting with your tax accountant was essential, in the past. We use online platforms to book calls with our qualified (ACCA/ATT/EA) tax specialists when you want them. These meetings are hosted live and recorded so that you can replay them anytime. This is not possible with face-to-face meetings. So now we do not believe you need “an accountant near me?”.
