Sometime ago, I made a google sheet to keep track of my POS materials and thought it would be nice if anyone could use it !
So I reproduced it as a web application, really easy to use.
Here is a screenshot of the app:
The only thing you have to do is editing the "Have" column.
Data are saved in your localStorage and can be exported / imported if needed.
