This a simple calculator based POS.
Want to design a calculator based software , which is as responsive (speed) as a simple calculator. Sales will be calculated, should be saved with date and time , biller panel should not be able to access daily sales , manager should be able to calculate daily sales and tally it , a button should be there on manager side when he tallies the sales with received amount.
A printout should come out on a thermal printer when biller finalizes the bill, an option should be their of "Wholesale" , when biller taps it , it should add a editable column of wholesale prices , which is Rs. 2 discount on products below 100 , Rs. 5 discount on products between Rs.200 and Rs. 100 and Rs. 10 on products above Rs. 200 , this is a general formula , which should apply automatically but is an editable manner , if a product has more or lesser discount on any specific product seller can change it. Then the bill get finalized.
Option should be there for adding customer name and contact number , if biller wishes to add, otherwise bills should be made as "Walking Customer".
Wholesale sales should be shown separately on manager side.
Thier should be a backup download option , and and option to clear all records when Admin wishes, but with a multiple prompt option.
Multiple billers can operate at separate systems and a biller can hold any biller on separate tab and start a new bill on a new tab.
Please give a quote. I think Laravel be a better option. Tell me what do you suggest.
