Our Fees

We charge €239 per month for our services.
All services above are included and we will get you up to date and keep you there as long as you send us the information.

Before we get year end accounts ready we need to get 12 monthly payments from you after you register with us. There are no extra costs when you join us as a client or for leaving.

You can claim all our fees against tax, which is up to 55% for sole traders and 12.5% for companies. Fees are paid by 12 Standing Orders so you have full control.

  • We are accountants but we specialise in applying technology to your accounts.
  • The most popular services we provide are:
  • 1. Set up a company in Ireland – we charge €199 to incorporate a company. This is for advice on your company in a face-to-face meeting or phone call with an accountant, plus formation of your company if that is the best solution for you.  These add-on services are also popular:
  • (a)  First Annual Return due within 6 months of registering a company €160.
