Advantage Accountancy & Advisory Ltd, Cardiff

Having experienced the preparation and submission of several R&D submissions in the past, I knew how onerous and time-consuming the process could be. I was only too pleased to meet with the team and be reassured that he would simplify the process and could provide advice and direction as to how the submission should be put together. We were happy with the size of the claim as it was larger than we anticipated, and due to the quality of the submission HMRC quickly processed the claim.
