There really isn't much! The team at DHiG has been very friendly towards our business over many years of working together; I have never had any issues with them in this regard ever since we started doing work for one another about 10 or so year ago now (when they were still called "KPM). They are great people who understand what you do as an organisation well enough not be too pushy/overbearing like some accountancy firms can sometimes feel when trying their best but just get it done quick without going overboard themselves - which makes sense considering how busy DH&L normally gets during January &[2]-March time period each financial yr due mostly from end-of month bookings / payments being made by clients wanting accounts up before new Xmas etc..
