    At the point of a sale, the transaction receives cash or allows payment on account in exchange for goods and stuff. This creates the inflow of cash or revenue and a corresponding outflow of product inventory. The primary objective of an extensive sales and inventory system is to optimize efficiency in recording each factor in the exchange.

    1. im not at coding sir… whats this?

      Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in C:\xampp\htdocs\GCCentrum\include\function.php on line 37

    2. how can I “unlock” remove function?
      I could add new employee/customer/product … etc. but in “action” column there is no “remove” button. only “Details” and “Edit” can be selected.

      Thank you

      • Hello Sir Raymond, As our requirement we don’t put delete on records but if you want I can provide you the the line of code to that.

    3. Dear sir,
      since i am new to PHp . can you tell me where to find the password? or how to add new user and decrypt thats hash password?

      • Good day sir, If you’re looking for the password that has been set in this post you have to use mysql for that. and to add users to you can either run the system and add user in it by using the admin account or you can use mysql to insert a query. And last, for decrypting I used Sha1 for that which you can’t decrypt it unless you’re going to change the encryption. I hope it helps.

    4. sir i want o know that when i buy item from the pos it does not updated the inventory and please tell what is the mean of on hand
