In my country there are many softwares for construction and projects budgets, the most well known is Presupuestos S10, but at the same time it has a lot of disadvantages, from my point of view. Since 2013, I am learning and writing VBA macros in order to use only Microsoft Excel for Mac 2011 to process my budgets. Hopefully this year I will finish this personal project, which I develop as a hobby on my free time (when my daughter Sofia is sleeping)
