Invoice System Using jQuery PHP MySQL And Bootstrap

PHP Invoice System

1. When user enters product name or product Id, it will shows auto suggestion of product name/id using jQuery autocomplete and then automatically fills the selected product id, product name, price and product quantity in their respective fields.

2. User can able to add delete any number table rows to add/delete product in the invoice system.

3. Calculation of total Line item price i.e. number item * unit price

4. Tax calculation.

5. Calculation of payment paid and payment due.

6. This invoice system has nice interface sample invoice form.

I had will add invoice print, invoice preview, invoice template, invoice emailing and some of the new features in the coming tutorial. Here is the invoice sample.


Invoice System Using jQuery AutoComplete


Create Sample Invoice System Database:

Before continuing this tutorial please create sample database with tables. For example I had created sample database in the name of ‘Invoice’ and it’s table products.

Use the following sample SQL queries to create your sample database with tables.

-- Database: `invoice`
USE `invoice`;

-- --------------------------------------------------------

-- Table structure for table `products`

  `productCode` varchar(15) NOT NULL,
  `productName` varchar(70) NOT NULL,
  `productLine` varchar(50) NOT NULL,
  `productScale` varchar(10) NOT NULL,
  `productVendor` varchar(50) NOT NULL,
  `productDescription` text NOT NULL,
  `quantityInStock` smallint(6) NOT NULL,
  `buyPrice` double NOT NULL,
  `MSRP` double NOT NULL,
  PRIMARY KEY (`productCode`),
  KEY `productLine` (`productLine`)

Insert some dummy data to test.

Add jQuery, jQuery UI and Bootstrap CSS Files To design This Sample Invoice System:

Create index.php file and add the following css files in it.

<link href="" rel="stylesheet">
<link href="" rel="stylesheet">
<link href="css/datepicker.css" rel="stylesheet">
<link href="//" rel="stylesheet">
<link href="css/sticky-footer-navbar.css" rel="stylesheet">
<link href="css/style.css" rel="stylesheet">

Please ensure following js files are added in your index.php file.

<script src=""></script>
<script src=""></script>
<script src=""></script>
<script src="js/bootstrap-datepicker.js"></script>
<script src="js/auto.js"></script>

Design Invoice Template Using HMTL and Bootstrap CSS:

Design your own invoice template using html and css. I had used html and twitter bootstrap to design this free invoice template.

Invoice System Table Row Add and Delete using jQuery:

I had done this dynamic table row add and remove functionality using jQuery. This functionality will helpful for user to do bulk deletion of product in this invoice generator.

Please refer my prevoius tutorial on this dynamic table row add and delete using jQuery.

  1. Add & Remove Table Rows Dynamically Using jQuery
  2. Dynamically Add and Remove Textbox Using jQuery

Here is the my jQuery script to add and remove tables rows dynamically.


//adds extra table rows
var i=$('table tr').length;
	html = '<tr>';
	html += '<td><input class="case" type="checkbox"/></td>';
	html += '<td><input type="text" data-type="productCode" name="itemNo[]" id="itemNo_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
	html += '<td><input type="text" data-type="productName" name="itemName[]" id="itemName_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
	html += '<td><input type="text" name="price[]" id="price_'+i+'" class="form-control changesNo" autocomplete="off" onkeypress="return IsNumeric(event);" ondrop="return false;" onpaste="return false;"></td>';
	html += '<td><input type="text" name="quantity[]" id="quantity_'+i+'" class="form-control changesNo" autocomplete="off" onkeypress="return IsNumeric(event);" ondrop="return false;" onpaste="return false;"></td>';
	html += '<td><input type="text" name="total[]" id="total_'+i+'" class="form-control totalLinePrice" autocomplete="off" onkeypress="return IsNumeric(event);" ondrop="return false;" onpaste="return false;"></td>';
	html += '</tr>';

//deletes the selected table rows
$(".delete").on('click', function() {
	$('#check_all').prop("checked", false); 

jQuery AutoComplete for Invoice Module:

I had integrated jquery UI autocomplete in this easy invoice software. Please refer my previous tutorial on this jQuery autocomplete.

  1. jQuery Autocomplete Multiple Fields Using jQuery, Ajax, PHP and MySQL
  2. jQuery Autocomplete Search using PHP, MySQL and Ajax
  3. jQuery Autocomplete Post Tagging System Like In WordPress

In my previous tutorial i had written hundreds of lines of code for this jquery UI autocomplete. I had over simplified number lines required for this jquery UI autocomplete in this tutorial.

Here is the my over simplified jQuery UI autocomplet script.

//autocomplete script
	type = $(this).data('type');
	if(type =='productCode' )autoTypeNo=0;
	if(type =='productName' )autoTypeNo=1; 	
		source: function( request, response ) {
				url : 'ajax.php',
				dataType: "json",
				method: 'post',
				data: {
				   name_startsWith: request.term,
				   type: type
				 success: function( data ) {
					 response( $.map( data, function( item ) {
					 	var code = item.split("|");
						return {
							label: code[autoTypeNo],
							value: code[autoTypeNo],
							data : item
		autoFocus: true,	      	
		minLength: 0,
		select: function( event, ui ) {
			var names ="|");						
			id_arr = $(this).attr('id');
	  		id = id_arr.split("_");
	  		element_id = id[id.length-1];
			$('#total_'+element_id).val( 1*names[2] );

Database Configuration For This jQuery Autocomplete Invoice System:

It always comfortable to keep database configuration and site level configuration in a separate config file. So please create config.php file and define your database connections details and site wide configuatation.


Site :
Author :muni
define('DB_HOST', 'localhost');
define('DB_NAME', 'invoice');

$con = mysqli_connect(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_NAME);
if( mysqli_connect_error()) echo "Failed to connect to MySQL: " . mysqli_connect_error();

Create Ajax Handler PHP File For This jQuery Autocomple Invoice Module:

Please create ajax.php file which is going to handle autocomplete ajax request. This will make connection to MySQL database and fetches the matched records from database, then finally sends that response to the client side to show suggestion to user.

Here is the my Ajax Handler PHP script.

Site :
Author :muni
require_once 'config.php';
	$type = $_POST['type'];
	$name = $_POST['name_startsWith'];
	$query = "SELECT productCode, productName, buyPrice FROM products where quantityInStock !=0 and UPPER($type) LIKE '".strtoupper($name)."%'";
	$result = mysqli_query($con, $query);
	$data = array();
	while ($row = mysqli_fetch_assoc($result)) {
		$name = $row['productCode'].'|'.$row['productName'].'|'.$row['buyPrice'];
		array_push($data, $name);
	echo json_encode($data);exit;

  • balu k

    its just my opinion .. i thought another one functionality like sending invoice pdf by email..

  • yes i already in the process to add those functionalities… i will add it soon… Thank you 🙂

  • Jim

    Excellent development, many thanks Muni, i just wonder if i want to add a discount value before calculation of every line.

  • Hi Jim,

    Yes You can … pls modify following script to add discount value..

    //price change
    $(document).on(‘change keyup blur’,’.changesNo’,function(){
    id_arr = $(this).attr(‘id’);
    id = id_arr.split(“_”);
    quantity = $(‘#quantity_’+id[1]).val();
    price = $(‘#price_’+id[1]).val();
    if( quantity!=” && price !=” ) $(‘#total_’+id[1]).val( (parseFloat(price)*parseFloat(quantity)).toFixed(2) );

  • jonah

    Excellent development and big thanks to you. I just wonder how possible it could be to have a quantity type field for example i can sell out drugs as tablets or as sackets with the price varying.

  • yes you can, add quanity type field as drop down in the table..based dropdown selection you change the price…

  • jonah

    I have tried implementing with a drop down but then the challenge I have is that it cant pick the price of the exact product. All it does is, it picks for me the quantity type and in my ajax script i am doing a SELECT but then I need to know how to filter in my WHERE clause so that i can pick the price of that product for that quantity type.

  • pls check on ajax request you are sending selected quantity type… if it yes .. then add add that quantity_type in where clause like that WHERE QUANTITY_TYPE = ‘selected quantity type’;

  • jonah

    this is how it is; $qtype=$_POST[‘qtype’]; //get the selected quantity type $mj=mysql_query(“SELECT * FROM productlist WHERE qtype=’$qtype'”);
    // the above statement does do what i want as it doesn’t filter records based on the chosen quantity type and product name;
    Also i wonder how possible it is to pass two different values with the onchange attribute such that my code can as below;

    $pname=$_POST[‘productName’];// product name passed through ajax $qtype=$_POST[‘qtype’]; //get the selected quantity type $mj=mysql_query(“SELECT * FROM productlist WHERE qtype=’$qtype’ AND product_name=’$pname'”);
    //this query would filter results based on the quantity type selected and the product selected

  • Ghufran Javed

    Hi Muni,

    First thanks for this wonderful invoice system script, i want to add extra field in it i.e. Other Charges/Courier Charges.

    So how can i add this and get the sum.

  • Roberto

    I found a problem while adding/deleting rows, here:

    //adds extra table rows
    var i=$(‘table tr’).length;

    Lets assume the first row has the id itemNo_1. We fill that row and proceed to add a second row, which will have the id itemNo_2. If we delete the first row, itemNo_1, and add a second row, we will end up with two rows with the same id, itemNo_2.
    To search for unassigned ids, I modified the code with this:

    //adds extra table rows
    for (i=1; i<=100; i++) {
    if (!$('#itemNo_'+i).val()) break;

    This will search for the next free id , from 1 to 100.

  • Amit Mishra
