I need to create web page, with inventory table. I'm doing bussines in gaming places with slots and bar. I need my employees to login to a web page, after login they will see a table with their starting stock and starting money. Through the shift they sell stock and create profits and pay out slots. I want them to input everything to my system and at the end of shift,the system will calculate the profits plus money they paid throughout the day or night. Once they click save and leave button, they cannot do any changes. Once the new shift start, the new employee will login and see the new starting stock plus starting money for the slots. Meaning the system should automatically show new starting stock and the money from previous shift. I have four businesses, so the login system need to be customazible so I can add each employee to different business location if I need. From the backend or admin page I should see which place make which profit plus how much money the paid out. Also it should record, where each employee worked, so I can see how many shifts they made a month. I'd also like to see reports for each moth for each business (alltogether four locations). I need it to be fully customazible as the stock and the slots are changing frequently. I also need it to be translatable from the back end, as I need this webpage to be in czech language. I don't mind to translate it myself, if you are czech native or speaking I don't mind if you do it yourself.
