  • We are a local charity who started to use Vicki and her team a few months back. How lucky we are to have found them! The wonderful Chelsey looks after us on a daily basis and Vicki visits us and provides advice as needed. Over the past few months we have benefited from their professionalism and our accounts are now presented in a way that assists us with our applications to grant giving trusts. We can also clearly see which fundraising activities are most effective and how to better manage our costs. Numerical have proved a real asset to date and to show how much they care, both Vicki and Chelsey now do some volunteer work for us!

  • Numerical took over our accounts around a year ago as we were in formed of their professional and helpful attitude towards businesses with complicated structures, we can confirm that all we heard was true and that all staff members at numerical are friendly and willing to help, no matter if the issue is big or small. I highly recommend Numerical to all business small and large.

  • We are a relatively small home care business that is continually expanding, so decided to use an accounts package. We needed to know where are business was at any given time and to foresee any difficulties around cash flow, to ensure that our business was stable at all times. Our bookkeeper was not familiar with Xero so we enlisted the assistance of Numerical to work alongside us. From our very first meeting with Vicki Sanders we were extremely impressed with her proactive attitude and drive. Vicki worked closely with myself and our bookkeeper ensuring that we had weekly phone calls, in-between email contact and skype calls. The high level of service and professionalism that Vicki and her team gave us, we decided to move over to Numerical for all our bookkeeping needs. Vicki worked tirelessly to get our us up to date, so our accounts were spot on (Vicki doesn’t do, anything but spot on).
    Working closely with Vicki since August 2016 I can honestly say that her down to earth, common sense, no jargon directness has been a god send. Through Vicki’s patience, I have a much clearer understanding and base knowledge of Xero, it’s potential and what the figures mean. I cannot recommend Vicki and her team at Numerical enough, we feel totally in control of our accounts and where the business is and how to drive it forward.
