Today I am going to show you a software that I just made with Laravel. It is a sales system, point of sale, POS or whatever you call it, which is used to keep track of the products that are sold, the sales, and so on.

It is a totally free and open source system; which means that you can use it at no cost, and modify it to your needs or customize it. Among its features we find:

1. It Uses Laravel in its latest version (as of this writing)
2. Bootstrap is used for styles
3. FontAwesome Icons
4. Fully responsive system, that is, it works on mobiles, tablets and computers
5. Inventory control with sale price, purchase price, profit, stock, etc.
6. Option to make sale, adding products
7. Checking inventory stock when selling
8. Subtraction of stock when selling
9. Printing of sales tickets on thermal printer
10. Sales report
11. User login and registration
12. User management
13. Customer registration
