We have been running our marketing business for a few years and thought we were doing okay for ourselves until David introduced us to a Xero Add-On called FATHOM, which was a real game changer for us. We discovered that with a few tweaks to our pricing packages, reducing our debtor days and overheads, our cash flow improved and we were making a healthier profit. David has a wealth of knowledge and is very professional - we have no hesitation recommending him!
