What our clients say

"Pat of Addup has looked after our accounts since we started Safewise 14 years ago. Throughout that time, she has always been reliable, approachable and quick to help whenever we’ve needed advice or support. She understands our business, explains things clearly and has played an important part in helping us grow. After 14 years of consistently excellent service, we wouldn’t hesitate to recommend her."

Gary Milligan Assoc (CIPD)

Director

"Working with Pat at Addup Consultancy helped in the running of our electrical business. Their deep understanding of the construction sector and SME's accounting means they speak our language and anticipate our needs. They handle everything from CIS and payroll to management accounts and year-end compliance, allowing us to focus on running our contracts and serving our clients. Their advice is always clear, practical and commercially focused, helping us to make confident decisions and plan ahead with real numbers rather than guesswork."

"I have been supported by Addup for the last 4 years. I have had invaluable help setting up my business, keeping track of finances, assistance with invoicing, VAT returns, HMRC enquiries as well as staff pay and end of year accounts. Of the utmost importance to me is trust, openness, and honesty. Pat has always given honest advice, taking time to guide and explain where necessary, minimising costs whilst maximising benefits to my company. I couldn't ask for more."

Addup has been excellent to work with across our group of companies. They're responsive, professional and have made managing our bookkeeping simple and stress free. I'd highly recommend them to any business looking for a reliable bookkeeping partner.
