About Point of Sale POS System Project

Moving on, this POS System project in PHP CodeIgniter focuses mainly on dealing with retail transactions with respect to total sales, purchases, and so on. Also, the system displays all the available information of suppliers, customers, products, sales, transactions, etc. In addition, the system allows managing product categories too by just entering its name and category code. The project only contains an Admin Panel. In an overview of this web application, the admin has access to everything and manages them easily. The admin has the right to manage the supplier’s list. For this, an admin has to enter details like the supplier’s name, address, and contact number. The supplier records are important while maintaining the purchase transactions. Also, to insert a customer’s record, he/she has to enter naming details, address, and contact of each.

Before proceeding towards the product section, an admin first has to add a new category and then simply manage new products by entering the product’s code, name, description, category, and pricing details. After all, an admin can manage sales transactions by selecting the customer’s name, payment method, product name, quantity, and price. This will automatically generate the total amount for the customer. The admin can enter numerous product entries at a single time for the total calculation. After each and every sales transaction, the system deducts the available quantity of each product. So, in order to maintain the quantity, the user can also purchase items for adding up the quantities in stock. For this, the user has to select the available products, enter quantity, price per unit, and discount amounts. After setting up this, the system automatically adds quantities to each of the purchase items.

Dues, and Sales Return

Under this section, the system lists out all the payment dues under the dues section. For maintaining the dues list, the user has to select on “Pay Later” option during sales transactions. Also, the system displays a table list under the admin’s dashboard with a number of remaining dues with their respective customers and product details. He/she can also view details regarding the dues and mark it as paid if he/she wants to, which directly references the total sales of the system. Another feature includes displaying sales information of each customer with their product, payment details, and marks if he/she has bills dues or not. Additionally, the user can manage all the sales returns by simply selecting any of the sales made by the customers and entering a certain quantity; which also affects the total product quantity.

Purchase Returns, Monthly and Daily Sales, and Export CSV

On the other hand, all the previous purchases made by the admin can also be returned if he/she wants to. In terms of managing its record, the user just has to select the purchase items and enter a certain quantity; which will also make changes to the total available products. The system also calculates the total sum of each returned product. In addition to it, the user can also view the number of sales made in a month and per day wise under the admin dashboard. With the representation of it, the system also calculates the total sales amount; not the dues one, but the paid ones, and displays it to the user. Besides, each section contains search functionalities and pagination with it.

  1. I could not login to the system which is provided in the 01 LOGIN DETAILS & PROJECT INFO.txt file. I think password or username provided is not correct.

    1. Login credentials are correct, we’ve checked it once again. Maybe that’s a different error, which may be related to your db connection. Can you please say about the error message you’ve got?

      1. I’ve got no error message, but I couldn’t login to the system. It keeps on showing login screen, i,e ‘Please login to continue..’

        1. Please check your database connection. If everything is perfect, then the problem might occur due to your latest PHP version. This particular project operates well on PHP 5.6.3. We recommend using that version for this project (as mentioned in the project overview table)

          1. I think this bug is not from the config connection database, I think your project code. If you kindly please give us the full project without hide some thing. cause many developer found this problem. Thank you!

          2. this is it, this is all we’ve got! there’s no hiding from us. Just look at the project overview table, this project works on PHP 5.6 (as recommended) make sure about your version!

      2. i have a similar problem i entered the given credentials but it doesn’t give any response. no feedback or anything

    1. First of there are other settings that need to be maintained and secondly, these projects are not targeted for Live productions. These are only meant to be for educational purposes.

      1. What can of settings should maintained for it to run on live web server I have made a few tweaks to the project to suite my needs but have failed to launch on a live server please kindly assist

      1. You can simply have a different PHP version either by installing a particular version or having apache and PHP files from a certain PHP version and replacing it with the current ones.

  2. Hi. Thank you for this. You are awesome! However, there are missing dependencies like raphael-min.js, jquery.sparkline.min.js etc. It’s no longer available in the new AdminLTE theme.

  3. An uncaught Exception was encountered

    Type: RuntimeException

    Message: Unable to locate the model you have specified: Auth_model

    Filename: /var/www/site/system/core/Loader.php

    Line Number: 344

    Backtrace:

    File: /var/www/site/application/controllers/Home.php
    Line: 7
    Function: model

    File: /var/www/site/index.php
    Line: 292
    Function: require_once

    The website is not starting, caught this error…

        1. That’s due to your current PHP version. Seems like you’re using PHP 7, but the recommended PHP version for this particular project is 5.6!

  4. It’s an awesome project I must commend it!
    Have managed to login and interact with all the modules and would suggest these;
    1. Can’t you allow entering of a specific amount of money when clearing a customer’s due instead of clearing it all at once coz a customer might not have brought the full amount for his or her due.

    2. Have also observed that the logic on the sales returns works in the opposite way. When you select yes for return of goods, I expect the right accounting entry to increase the stock of that product and not reducing it.

    It’s a good project that implements real life scenarios, kudos! Though I’ll have to rewrite it in CodeIgniter 4 and extend some functionalities of your source code. However, your code naming convention is also not easy to understand but figure it out.

    Thanks once again!!

  5. Hello, it is really important what you do, you help a lot of people, thank you sincerely.

    Me, if possible I would like you to tell me the name of the project in which you used a checkbox, thank you in advance

  7. I can’t login when I create new account. Error message is “ERROR! Your account is not active, Please contact administrator”. How can I solve and make all new account can login to your website ?

    1. There’s no option that will let you create a new account from the system. Seems like you’ve added that yourself. In that case, please check the database values!

  8. Hi admin, do you have warehouse management with module.
    1. Goods in and out?
    2. Multiple warehouse?
    3. Stock report and stock ledger ?

  9. Hey Admin … I want to create the app users directly from database.. I want to know which methode you use to encrypt the password…

  10. So if someone edits the code and makes it work on live server, can he use it for that purpose?
