What makes Carpenter Box really stand out is their attention to detail and personal involvement in our business. They understood our requirements and were there to continually support us. Carpenter Box have helped us to tailor their service by understanding what we need. We have a relationship with the team at Carpenter Box we can really rely on. We’ve had the same account manager since the outset, so they really understand our business and how we’ve grown. If we have any questions I feel we get an almost instant response, which is really important to a business like ours. Carpenter Box have absolutely excelled for our business. We refer to them as our accounts department, which I think says a lot. I wouldn’t hesitate to recommend them to any other start-up or small business.

With Carpenter Box we have seen a dramatic improvement in the way in which we produce our monthly reporting which has really allowed us to be more transparent and efficient when planning ahead. Chris has been fantastic in advising on a wide range of accounting and tax issues in the motor industry and I really value his sector insight and enthusiasm. The team at Carpenter Box are incredibly helpful and always on hand when I’ve had any pressing issues or queries. Chris and his team have been a real asset to our business which reassured me in my decision to switch services from our previous firm of accountants. The support that Carpenter Box provides to our business has helped me to continue our growth path with confidence.

Carpenter Box provide us with a complete service. They look after everything from audit and payroll to sorting out our pension schemes and personal tax planning. We really value the range and depth of expertise that they have under one roof, because property and construction can be a complex industry, but the team have excellent knowledge of the sector.
