Create dedicated pools, import codes from TXT or CSV files, distribute available codes through a controlled workflow and keep track of inventory and operational activity from the WordPress administration area. #### Key Features * Pool Management – organize One-Time Codes in dedicated pools for products, campaigns or other use cases. * Inventory Overview – review available and distributed codes with filters and inventory context. * TXT and CSV Import – import One-Time Codes into selected pools. * Import Rollback – undo eligible imports when no One-Time Codes from the import have been distributed. * Controlled Distribution – One-Time Codes are issued through a controlled workflow designed to help prevent duplicate issuance. * Activity History – review important operational events without storing distributed One-Time Code values in the activity history. * Retention Management – configure automatic activity retention and scheduled cleanup. * WordPress Roles and Capabilities – administrative access follows the native WordPress permission system. * Localization Ready – uses the WordPress localization system and supports translations provided through WordPress.org. #### Data-Minimal by Design Voucher Manager stores only the information required for its core functionality. One-Time Code values are not stored in Activity history. #### Simple Workflow 1. Create a pool. 2. Import One-Time Codes. 3. Distribute one available code. 4. Review inventory and operational activity. Voucher Manager is a complete, usable plugin designed to provide real value for everyday One-Time Code management. ## Screenshots [⌊Dashboard with inventory overview, quick actions and recent activity.⌉⌊Dashboard with inventory overview, quick actions and recent activity.⌉[ Dashboard with inventory overview, quick actions and recent activity.

Voucher Manager stores available codes in pools and provides a controlled workflow for distributing them. ### What file formats can I use to import One-Time Codes? Voucher Manager supports TXT and CSV files for importing One-Time Codes. ### Can I organize codes for different products or use cases? Yes. One-Time Codes are organized in separate pools, allowing different products, campaigns or other use cases to be managed independently. ### Can an import be undone? Yes, when the import is still eligible for rollback. An import can only be undone when no One-Time Codes from that import have been distributed. ### Are distributed One-Time Codes stored in the activity history? No. Distributed One-Time Code values are not stored in the activity history. ### Can activity history be cleaned up automatically? Yes. Voucher Manager provides configurable activity retention and automatic cleanup through WordPress-Cron. ### Does Voucher Manager support translations? Yes. Voucher Manager uses the WordPress localization system and supports translations provided through WordPress.org. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “MJS-Productions Voucher Manager” is open source software.
