Accounting in Lisburn & Belfast that lets you sleep at night

We provide proactive, plain-English accountancy support for business owners across Lisburn, Belfast and Northern Ireland, so you can feel confident, stay compliant, and grow with clarity.

Who We Help

For business owners who want more than “once-a-year” accounting

If you’re:

  • just getting started,
  • switching from an accountant who doesn’t communicate,
  • or trying to scale and need better visibility…

…you’re in the right place.

We don’t wait until year-end to tell you what happened, we help you understand your numbers throughout the year, so you can make decisions with confidence.

What Our Clients Say

I’ve known Melanie for 10 years and would implicity trust her with my business and to give me sound and sensible advice. As a Xero certified partner, she recently showed me Xero’s hubdoc add on which will save me hours, help me understand my figures better and also help with Making Tax Digital! I would highly recommend Melanie and her team at M Squared Accountancy

Alison Matthews VirtuAli Admin Solution

Melanie was my business mentor and was so helpful, knowledgeable and easy to work with. I learned a lot during my time with her as she had already been through the process herself and was able to guide me. I really enjoyed working with her as she is so motivating and enthusiastic. Her professionalism is second to none. Highly recommend Melanie on every level.

Linda Hyde

Melanie has been incredible for our business. She takes care of all our bookkeeping, tax returns, and payroll with professionalism and accuracy, which takes a huge weight off our shoulders and allows us to focus on growing the business. She is very knowledgeable, easy to talk to, and always has a smile on her face, which makes working with her such a pleasure. We honestly don’t know what we’d do without her — she’s truly an invaluable part of our team!
