Imagine: your WordPress store manually uploads orders to 1C every morning. One day you forget — and the client leaves. Ready integration plugins either don't support your 1C version or cost as much as half the site. We wrote a custom plugin in 3 days: it automatically sends data to 1C on a schedule, logs errors, and doesn't charge for updates. This approach saves your budget and time — a custom plugin typically pays for itself in 2-3 months by eliminating license fees. Contact us for a free evaluation of your task within 1 day.
Our team has 8+ years of experience in WordPress plugin development, with over 200 projects of varying complexity. We guarantee compatibility with the latest WordPress and PHP 8.x. A custom WordPress plugin solves exactly your business tasks, without unnecessary code.
Use Cases for a Custom WordPress Plugin
Ready plugins from the marketplace often contain redundant code that slows down the site. For example, a caching plugin may add hundreds of lines of CSS you don't need. A custom plugin runs 2-3 times faster because it has no bloat. Also, ready solutions rarely account for your architecture specifics: custom post types, metaboxes, integrations with corporate APIs. We write the plugin strictly for your task, using only the necessary WordPress hooks and filters.
Creating a WordPress plugin starts with requirements analysis and architecture design. We use modern design patterns and SOLID principles.
How a Custom Plugin Solves Performance Issues
A typical problem is N+1 queries due to suboptimal WP_Query. A custom plugin can implement pre_get_posts and transients, reducing the number of database queries. For speed-critical tasks we attach Object Cache (Redis), cutting TTFB by 30-40%. For instance, to display popular products we use pre_get_posts filtering and store the result in a transient for an hour. This reduces queries from 5 to 1. With Redis enabled, TTFB drops by 30-40%. A custom plugin lowers site hosting costs — hosting savings can reach 30%.
Comparison of ready vs custom plugin:
| Parameter | Ready Plugin | Custom Plugin |
|---|---|---|
| Code size | 10+ MB (often) | 0.5-2 MB |
| Unnecessary DB queries | Yes | No |
| Load time | +200-500 ms | +50-100 ms |
| Adaptation to architecture | Difficult | Full |
Common problems with ready plugins and their solution via custom development:
| Ready Plugin Problem | Custom Solution |
|---|---|
| Bloated code, 10+ MB | Only needed logic, 0.5-2 MB |
| N+1 DB queries | Optimized pre_get_posts |
| Conflicts with other plugins | Isolated namespace |
| Slow support | Direct access to developer |
How a Custom Plugin Ensures Security
Security is a key development aspect. We follow WordPress Coding Standards and recommendations from the WordPress Plugin Handbook. Specifically, all AJAX handlers check nonces, SQL queries are escaped via $wpdb->prepare, and output is escaped through esc_* functions. As stated in WordPress Plugin Handbook, any user input must be sanitized. This eliminates XSS and SQL injection.
How We Develop Custom Plugins
The standard plugin structure includes folders includes, admin, public, and a main file. We follow the WordPress Plugin Handbook standards. The main file contains a header and bootstrapping:
<?php
/**
* Plugin Name: My Custom Plugin
* Plugin URI: https://example.com/my-plugin
* Description: Description of the plugin functionality.
* Version: 1.0.0
* Requires at least: 6.0
* Requires PHP: 8.1
* Author: Company Name
* Text Domain: my-plugin
*/
if (!defined('ABSPATH')) {
exit;
}
define('MY_PLUGIN_VERSION', '1.0.0');
define('MY_PLUGIN_DIR', plugin_dir_path(__FILE__));
define('MY_PLUGIN_URL', plugin_dir_url(__FILE__));
require_once MY_PLUGIN_DIR . 'includes/class-my-plugin.php';
function my_plugin_init(): void {
$plugin = new My_Plugin();
$plugin->run();
}
add_action('plugins_loaded', 'my_plugin_init');
Loader pattern — register all hooks in one place:
class My_Plugin {
private array $actions = [];
private array $filters = [];
public function __construct() {
$this->define_admin_hooks();
$this->define_public_hooks();
}
private function define_admin_hooks(): void {
$admin = new My_Plugin_Admin();
$this->add_action('admin_enqueue_scripts', $admin, 'enqueue_styles');
$this->add_action('admin_menu', $admin, 'add_plugin_admin_menu');
}
private function add_action(string $hook, object $component, string $callback, int $priority = 10): void {
$this->actions[] = compact('hook', 'component', 'callback', 'priority');
}
public function run(): void {
foreach ($this->actions as $hook) {
add_action($hook['hook'], [$hook['component'], $hook['callback']], $hook['priority']);
}
foreach ($this->filters as $hook) {
add_filter($hook['hook'], [$hook['component'], $hook['callback']], $hook['priority'], $hook['accepted_args'] ?? 1);
}
}
}
For custom tables we use dbDelta on activation:
register_activation_hook(__FILE__, function () {
global $wpdb;
$table = $wpdb->prefix . 'my_plugin_data';
$charset = $wpdb->get_charset_collate();
$sql = "CREATE TABLE {$table} (
id bigint(20) NOT NULL AUTO_INCREMENT,
user_id bigint(20) NOT NULL,
data_key varchar(255) NOT NULL,
data_value longtext,
created_at datetime DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (id),
KEY user_id (user_id),
KEY data_key (data_key)
) {$charset};";
require_once ABSPATH . 'wp-admin/includes/upgrade.php';
dbDelta($sql);
add_option('my_plugin_db_version', MY_PLUGIN_VERSION);
});
Settings page via Settings API:
class My_Plugin_Admin {
public function add_plugin_admin_menu(): void {
add_options_page(
'My Plugin Settings',
'My Plugin',
'manage_options',
'my-plugin',
[$this, 'display_plugin_setup_page']
);
}
public function __construct() {
add_action('admin_init', [$this, 'register_settings']);
}
public function register_settings(): void {
register_setting('my_plugin_options', 'my_plugin_api_key', [
'type' => 'string',
'sanitize_callback' => 'sanitize_text_field',
]);
add_settings_section('my_plugin_main', 'Main Settings', null, 'my-plugin');
add_settings_field('api_key', 'API Key', function () {
$value = get_option('my_plugin_api_key', '');
printf('<input type="text" name="my_plugin_api_key" value="%s" class="regular-text">', esc_attr($value));
}, 'my-plugin', 'my_plugin_main');
}
public function display_plugin_setup_page(): void {
if (!current_user_can('manage_options')) {
return;
}
echo '<div class="wrap"><h1>' . esc_html(get_admin_page_title()) . '</h1>';
echo '<form method="post" action="options.php">';
settings_fields('my_plugin_options');
do_settings_sections('my-plugin');
submit_button();
echo '</form></div>';
}
}
For AJAX handlers, always check nonce:
add_action('wp_ajax_my_action', function () {
check_ajax_referer('my_nonce', 'nonce');
// processing
wp_die();
});
What's Included in Development
The development cost includes:
- Requirements analysis and technical specification.
- Architecture design: hooks, tables, settings.
- Coding with WordPress Coding Standards and strict PHP 8.0+ typing.
- Custom database tables via dbDelta.
- Settings page via Settings API.
- AJAX handlers with nonce protection.
- Integration with external REST and SOAP APIs.
- Unit testing with WP_Mock.
- Complete documentation: all hooks, shortcodes, methods.
- Source code with unlimited usage license.
- 2 months of free support and bug fixes.
Work Process
- Analysis — gather requirements, prototype, approve TOR.
- Architecture — design code structure, database, hook system.
- Development — write code with WordPress standards, strict typing.
- Testing — unit tests via WP_Mock, integration tests, compatibility check.
More about testing
We use WP_Mock for unit tests and run integration tests on a staging server with real data. - Documentation — describe all hooks, shortcodes, methods, settings pages.
- Support — 2 months free support after handover.
Estimated Timelines
Cost is calculated individually based on complexity. Typical timelines:
- Simple plugin (shortcode + settings page) — 2–3 days.
- Medium (custom tables, AJAX, API integration) — 5–8 days.
- Complex (metaboxes, custom tables, intricate logic) — from 10 days.
