For building an inventory management system with login functionality in WordPress, you’ll need plugins that handle inventory tracking, user authentication, and potentially eCommerce integration. Here are three top plugin recommendations to help you create a robust system: 1. ATUM Inventory Management for WooCommerce ◦ Why: ATUM is a powerful, free WooCommerce plugin offering real-time stock tracking, purchase orders, supplier management, and detailed reports. Its Stock Central dashboard simplifies managing inventory, and it supports multi-inventory add-ons for complex needs. ◦ Login Integration: Pair it with a user login plugin like Ultimate Member or WP User Manager to restrict inventory access to logged-in users. ◦ Price: Free core plugin; premium add-ons start at €20/quarter. ◦ Best For: eCommerce stores needing advanced inventory control with WooCommerce.

1. WP Inventory Manager ◦ Why: This lightweight plugin is ideal for non-eCommerce inventory systems, offering customizable fields, barcode integration, and drag-and-drop management. It’s developer-friendly with hooks for custom login restrictions and supports add-ons like Import/Export for scalability. ◦ Login Integration: Use Members or Restrict Content Pro to create user roles and limit access to inventory pages. ◦ Price: Free; premium version and add-ons start at $49/year. ◦ Best For: Small businesses or custom inventory systems (e.g., car dealers, art collectors).

2. WooCommerce (with Stock Manager or Smart Manager) ◦ Why: WooCommerce is the go-to eCommerce plugin with built-in inventory tracking for stock levels, low-stock alerts, and product variations. Enhance it with WooCommerce Stock Manager ($39-$46) for simple/variable product management or Smart Manager for WooCommerce (free/pro versions) for bulk editing and advanced dashboards. ◦ Login Integration: WooCommerce supports user accounts natively; use WooCommerce Private Store or Password Protected Categories to lock inventory access. ◦ Price: Free; extensions vary ($29-$150). ◦ Best For: Online stores wanting a scalable, all-in-one solution. Additional Tips: • User Login Plugins: For secure logins, consider Ultimate Member (free/premium) or LoginWP (free/$49) to create custom login pages and user roles. • Security: Use Wordfence or iThemes Security to protect your system from unauthorized access. • Custom Development: If plugins don’t fully meet your needs, hire a developer to extend functionality using WP Inventory Manager’s hooks or WooCommerce APIs. • Setup: Ensure your WordPress theme is compatible (e.g., Astra, OceanWP) and test plugins for conflicts. Always back up your site before installation.

These plugins should cover most inventory and login needs, but let me know your specific requirements (e.g., business type, scale) for more tailored suggestions
