About WP ERP

WP ERP is an open-source enterprise resource planning plugin for WordPress, developed by weDevs. It turns a WordPress site into a back-office system by bundling core modules for human resource management, customer relationship management and double-entry accounting.

A project management component is also included, and a long list of add-ons extends the plugin: custom field builder, employee recruitment, document manager, payroll, attendance management, payment gateway, HR frontend, WooCommerce integration, email campaign, deals, workflow, reimbursement, inventory, SMS notification, asset manager and Gravity Forms support, plus contact sync with Salesforce, HubSpot and Mailchimp. The documentation covers setup, and a WordPress Playground link lets you try it in the browser.

It requires PHP 5.6 and WordPress 4.4 or later, and building from source involves composer and npm steps. The repository metadata does not state a license, so check the plugin's terms, and note that it runs inside a WordPress installation you host yourself.
