๐ Hi, I just complete studying base for building web application by Typescript, want to learn and improve more then i realize my dad's side job is being messed up with a lot of bills and orders, so i decided to build an app to help my daddy manage them easier.
There are many kind of order but 3 are main and some other. We can add, edit, change state of order and it will automatically calculate the revenue.
In addition, we can manage other things like customer list, material list and service list, there is a password div block user to interact, a small protection.
Finally, the revenue calculated from all the order and material list.
