Frequently Asked Questions

I'm interested, what should I do now?

Call us and arrange a free meeting. At this meeting, we will discuss your needs, what the solution is, how we will go about it and the charges. It's an informal meeting with your very best interests at heart.

I'm switching from another accountant, will you help me?

Absolutely! We take care of everything. It's as simple as a standard letter called a "professional clearance letter" being sent from us to your existing accountant. They will then provide us with a "handover pack" containing all the information we require to set up your opening position. 

We then commence our usual services for you leaving you to focus on what matters most in your business.

I'm new to all this, help!

We are very experienced at helping people who are new to business.

We have strong internal processes that will take you through registering for self assessment as well as complying with all legal requirements as you go forward. We will guide you at each step of the way and will always be there to take your phone call queries.

Do I really need an accountant?

Some people have friends who offer to help them complete their tax return. Others feel they can tackle it themselves.

Given that obtaining an accounting qualification is 6 years hard studying along with extremely difficult exams and years of practical, it's unlikely that any route other than using an Accountant is going to be successful for you. Wanting to dodge accounting fees doesn't make someone an expert. It may seem like you are saving money, but at what other costs?

Is your tax bill higher than it should be? Or your accounting records just plain wrong? Is a liability to the taxman building up in the background only to erupt at the most inconvenient moment?

Whoever you choose, make sure they are suitably qualified and able to look after your best interests...
