The system is very user friendly and it has the ability to hold multiple contracts at once so you can manage several projects without having too many tabs open in your browser window! It also allows me easy access from my mobile device which makes life much easier when I am out on site visits etc. There are some features that could be improved but they don't seem overly important overall - maybe just minor cosmetic things rather than functional issues? We have been able use buy manager since we started using BIM software about 2 years ago now and there was no other way back then (we used an antiquated program called Sage X3). This allowed us better control over our budgeting process by being more efficient and effective managing all aspects related to our project spendings including cost management & reporting. In addition this made sure everything went through one centralised source making.
