What Our Clients Say

  • "Izzi has been with us since just after our inception. We really could not have done it without him. Initially there was so much to learn and he was there every step of the way."

    Tracy - Kitchenality Ltd

  • "Izzi and his team have been invaluable and a core reason for our success and continued growth. Would highly recommend ProsperFi to anyone."

    Beth & Maddy - Up The Anti Ltd

  • "Izzi is proactive, always on-hand, understanding and very knowledgeable. Having previously used another accountancy firm for many years, ProsperFi have changed the game for me."

    James - Js Power Services Limited

  • Richard - Rickards Oliver Limited - Chartered Surveyors and Valuers

    We run a small family firm of Chartered Surveyors. We came to Izzi with a financial plan for a business that we had not yet built - he helped us to bring it to life and to show us a route to making it profitable to support our family needs.

    Many people view accountancy as dull, or as a distraction from doing business. The real value that a good accountant provides is in the advice they give. Izzi is a master at interpreting the numbers so that they tell a story. From that comes the basis for a sound financial plan and being able to understand what we need to do to help our business to grow. 

    Izzi has shown us how to use Xero technology to keep our records in the right way so that compliance for VAT and HMRC are built into our financial planning and business practices. This means that the accountancy work is relatively simple and Izzi and his team can focus on giving brilliant advice tailored to the needs and growth stage of our business.

  • Oksana and Richard - R S C Technology

    We've been working with ProsperFi for 3 months, and as a limited company, we couldn't be more impressed with the level of service and expertise they provide. From day one, Izzi and the team have been proactive, responsive, and incredibly knowledgeable.

    Recently we had a pricing strategy with him which resulted in cutting down quoting from 3 days to 3 hours. Absolutely blown away how knowledgeable Izzi is and how the changes he proposed made such a big difference!

    It's a huge relief knowing our accounts are in such capable hands. Highly recommend to any business looking for reliable and professional accountancy support!
