What our customers are saying

It has been a pleasure partnering with ARKK Solutions to deliver our ESEF tagged Annual Reports since 2021. ARKK are extremely supportive and responsive partners, ensuring that we are kept up to date on new reporting requirements, participating in meetings with our auditors and delivering to agreed timelines. We plan to continue working closely with ARKK as our ESEF journey continues.
Janette Moriarty , Group Financial Reporting Director at Kerry Group

Over the last year and a half, ARKK has been instrumental in launching our ESEF offer. They have been hugely supportive and responsive to our team providing clear, friendly advice and expertly guiding them through the new reporting requirements. Simply outstanding service and a real pleasure to work with them.
Chris Parsons , Production Director at Radley Yeldar.

ARKK has truly been an invaluable partner to us. In addition to their technical expertise and knowledge of the regulations, what I valued the most was their flexibility and reactivity throughout the whole process. I now feel much more comfortable with this topic and would not consider doing another ESEF project without ARKK to support us.
