I am an IT contractor and sell my services through my Ltd company QDOS is managing. E.g. all sort of tax payments, expense tracking, etc. are handled by them with minimal work for me left. Also always providing suggestions for the best on my side. QDOS is handling my requests in less then 3 hours and are always helpful in explaining certain processes, no matter when and what I ask. I am very happy and can only recommend their services. I use also insurances of them which can also be individualised!
