Here's what some of our clients have to say

  • Dolores Connolly (JF Smyth Tiling)

    Liz helped our family business on many occasions. I wasn't surprised when she decided to extend this knowledge to other SME's in Ireland through SISgate pro. Liz acted as a friend, advisor and great support to us through many good bad and indifferent times. Without support our business and ultimately our personal life would have been a lot more difficult.

  • Marie Therese (EAM Group)

    We engaged with SISgate pro for business planning advice but got much more. The SISgate team are friendly, open and honest and strive to support while helping business owners like myself get back to what we do best. Just knowing that we have this support and the vast amount of experience of SISgate at our fingertips helps put our minds at ease.

  • Eugene and Roxana (Canvas Cafe and Primo Chef)

    We are a small chain of cafe/restaurants, and being a family business, it means we both work within the business full-time. Our livelihoods and those of our team depend on it. SISgate has helped us reduce our costs without compromising on quality and have helped us actually improve quality. Since we started working with them, we've got back to concentrating on our passion for our business and we are happy to say we are getting stronger everyday. We are currently embarking on an expansion plan, we are looking forward to growing with the continued support of SISgate.
