Joe Dowling – Managing Director
Joe Dowling Transport Limited

“Finlay-Mulligan & Co have been a great help to our renewable energy business not just as accountants but as advisors on our initial corporate structure and how to structure our business in the most tax efficient way. They also helped to get us set up with our online accounting software which is seamless and makes it easy for us to keep on top of our accounts throughout the year. Very professional and friendly service and always reasonable on price”.

Conor McAllister – Managing Director
Meridiem Renewables Limited

“Initially Finlay-Mulligan & Co began as providing a bookkeeping service to us. As we grew, we needed a full time bookkeeper which Finlay-Mulligan & Co assisted with providing. Finlay-Mulligan & Co then helped us get set up on cloud accounting via Sage50 cloud which has enabled our financial processes to operate more efficiently. As we continue to grow as a business, Finlay-Mulligan & Co have become outsourced financial controllers which has contributed to the success of the business.”
