About this plugin
CostHarbor Supplier Updates for WooCommerce imports supplier CSV price lists through a safety-first workflow: upload, map, configure, preview, apply, and review results. It matches both product and variation SKUs. It never creates products. Invalid, duplicate, and unmatched rows are blocked. Large proposed price changes are highlighted using a configurable threshold. Every apply stores the prior supplier cost and regular price for rollback. All processing and data storage stays in WordPress and WooCommerce. The plugin sends no telemetry, analytics, CSV content, or store data to external services. Privacy CostHarbor Supplier Updates for WooCommerce processes CSV content locally and stores import summaries, rollback snapshots, and supplier cost metadata in the site’s WordPress database. It does not transmit data externally. Import history is retained for the 20 most recent imports. By default, uninstalling preserves supplier costs and import history as business data while removing temporary data. Administrators can explicitly opt into permanent data deletion before uninstalling.
