Just a few kind words from our lovely clients and associates

Sarah and her team have worked very hard for Mezze Restaurants since our business opened in 2009. I have found them to be highly competent, with an eye for accuracy and detail. They have proven to be honest, reliable and capable.

Codex Absolute has kept our books since 2009. From starting, their staff have become part of the WSI team and fit in well with the rest of the office staff. They run the bookkeeping including invoicing and any chasing of payments. Their work is accurate and they have the right balance between working autonomously and seeking the advice of one of the directors when required. They pro-actively recommend ways to improve our systems. I have no hesitation in recommending Sarah and her team to any other business.

Codex Absolute Ltd came to us highly recommended by our accountants and, since working on our accounts, Sarah and her team have lived up to their billing. It’s always a pleasure to see them and thanks to their work, we now have a greater insight into our financial situation than at any time in the last 9 years without them. Their attention to detail and ability to quickly sort through our monthly transactions has meant I can concentrate on running the company and look after our clients. I would recommend them without hesitation.
