Every business needs an accountant, my business being a new business, most of all. I was introduced to Emma and the Mercury team back in January 2021 and from the start of the engagement they have made me feel completely at ease. Not having the knowledge around accounting, the team have walked me through every step, advised and educated along the way. As a new business you need to feel confident and comfortable with the company looking after your business’s accounts. Over the last year I have found Mercury to be exactly that, they have improved my businesses efficiency, while educating me throughout the process. They are a really friendly, honest and trustworthy team and I would recommend them to any other businesses looking for someone to look after and run their accounts for them.”
